In AJKL, If M ZJ Is Seven Less Than MZL And MZK Is 21 Less Than Twice MZL, Find The Measureof Each Angle?

Answers

Answer 1

The measures regarding the angles of the triangle are given as follows:

x = 26.<P = 116º.<Q = 21º.<R = 43º.

How to obtain the angle measures?

The angle measures are defined as follows:

<P = 5x - 14.<Q = x - 5.<R = 2x - 9.

The sum of the measures of the internal angles of a triangle is of 180º, hence the value of x is obtained as follows:

5x - 14 + x - 5 + 2x - 9 = 180

8x = 208

x = 208/8

x = 26.

Then the measures are given as follows:

<P = 5(26) - 14 = 116º.<Q = 26 - 5 = 21º.<R = 2(26) - 9 = 43º.

Answers

12 servings of rice require six cups of rice. In order to make 12 servings, 6 cups of rice would be needed, or 2/5 of a cup.

1. It takes 2 cups of rice to make 5 servings.

2. Divide 12 by 5 to determine how many cups of rice are required to prepare 12 servings.

3. The final product is 2.4 cups.

4. Round up to the nearest whole number, which is 6 cups, to get 12 servings.

You will require 6 cups of rice to produce 12 servings of rice. The number of servings that can be made from 2 cups of rice can be used to determine this. 5 servings can be produced from 2 cups of rice. This indicates that 2/5 of a cup of rice is needed for each serving. Divide 12 by 5 to see how many cups of rice are required for 12 servings. This results in 2.4 cups of liquid. Round the amount up to the nearest whole number, which is 6 cups, to make 12 servings. 6 cups of rice are therefore required to make 12 servings.

a certain bacteria population obeys the population growth law. it is observed that the doubling time for the population is 4 hours. the length of time it will take for the population to increase to 3-times its original population is

Answers

According to the population growth law, the size of a population grows exponentially over time, with a growth rate proportional to population size. If the population doubling time is t, then the population size P can be written as:

[tex]P = P_0 * 2^{t/t_d)}[/tex]

where P_0 is the initial population size, t is the time elapsed, and t_d is the doubling time.

To find the time it will take for the population to increase to 3 times its original population size, we can set [tex]P = 3P_0[/tex] and solve for t:

[tex]3P_0 = P_0 * 2^{t/t_d}[/tex]

Dividing both sides by [tex]P_0[/tex] gives:

[tex]3 = 2^{t/t_d}[/tex]

Taking the logarithm of both sides (using any base) gives:

[tex]log(3) = log(2^{t/t_d} )[/tex]

Using the logarithmic identity

[tex]log(a^b) = b*log(a),[/tex]

we can rewrite this as:

[tex]log(3) = (t/t_d)*log(2)[/tex]

Solving for t, we get:

[tex]t = t_d * (log(3)/log(2))[/tex]

Substituting [tex]t_d[/tex] = 6 hours (given in the problem), we get:

[tex]t = 6 * (log(3)/log(2)) hours[/tex]

Simplifying using the change of base formula

[tex](log(a)/log(b) = log_b(a))[/tex], we get:

[tex]t = 6 * log_2(3)[/tex] hours

Therefore, the answer is (f) None of the above.

The image of a trapezoid is shown. An isosceles trapezoid with a short base of 3 meters and a height of 5 meters. The portion of the large base from the left vertex to the perpendicular is 4 meters. The portion of the large base from the right vertex to the perpendicular is 7 meters. What is the area of the trapezoid? 70 m2 38 m2 35 m2 19 m2

Answers

The area of the trapezoid is approximately 42.5 square meters. So, the answer closest to this value is 38 m^2.

What is trapezoid ?

A trapezoid is a quadrilateral with at least one pair of parallel sides. In a trapezoid, the parallel sides are called the bases of the trapezoid, and the non-parallel sides are called the legs. The height of a trapezoid is the perpendicular distance between the bases.

There are several types of trapezoids, including isosceles trapezoids, where the legs are of equal length, and right trapezoids, where one leg is perpendicular to both bases. Trapezoids are commonly used in geometry and can be used to find the area of various shapes, such as triangles and rectangles.

To find the area of the trapezoid, we can use the formula:

Area = (1/2) x (sum of bases) x height

Since the trapezoid is isosceles, the length of the two parallel sides are the same. Let's call that length "x". We can use this information to set up an equation:

3 + 4 + 7 + x = 2x

Simplifying, we get:

14 + x = 2x

x = 14

So the length of both parallel sides is 14 meters.

Now we can plug in the values into the area formula:

Area = (1/2) x (3 + 14) x 5

Area = 8.5 x 5

Area = 42.5

Therefore, the area of the trapezoid is approximately 42.5 square meters. So, the answer closest to this value is 38 m^2.

Answers

At the end, Ann saves a total amount of 3 dollars according to the money she spent and on allowance according to the percentages.

Total Allowance of Ann = 15 dollars

Spent on food by Ann = [tex]\frac{15}{100}[/tex]*50

On food = 50 × [tex]\frac{15}{100}[/tex] = 7.5 dollars

Spent on stationary = 30% of Allowance

On stationary = 30 X[tex]\frac{15}{100}[/tex] = 4.5 dollars

Therefore, Money saved by Ann = Total Allowance - Money spent

Money saved = 15 dollars - 7.5 dollars - 4.5 dollars = 15-(7.5+4.5) dollars

Money saved = 3 dollars

How many kilograms of compost are in the barrel?
.....kilograms?

Answers

The kilograms of compost in the barrel is 5.6 kg

How to determine the kilograms of compost in the barrel?

From the question, we have the following parameters that can be used in our computation:

Amount filled on day 1 = 1/4

Remaining space = 4200 grams

The number of kilograms in the barrel is calculated as

Remaining space = (1 - 1/4) * Original space

Substitute the known values in the above equation, so, we have the following representation

(1 - 1/4) * Original space = 4200 grams

Convert to kg

(1 - 1/4) * Original space = 4.2 kg

So, we have

Original space = 4.2 kg/(1 - 1/4)

Evaluate

Original space = 5.6 kg

Solve the following system of inequalities graphically on set of axes below. State the coordinates of a point in the solution set. ​

Answers

Answer:

  see below for a graph

  (-8, 4) is in the solution set

Step-by-step explanation:

You want the graph and a solution point for the inequalities y ≤ -6/5x -4 and y ≥ 2/5x +4.

Graph

The solid boundary line of the first inequality will cross the y-axis at -4, and will have a "rise" of -6 units for each "run" of 5 units. Shading is below this boundary line.

The solid boundary line of the second inequality will cross the y-axis at +4 and will have a "rise" of 2 units for each "run" of 5 units. Shading is above this boundary line.

Solution set

The boundary lines make an X shape on the graph, crossing at the point (-5, 2). The solution set is in the left quadrant.

Point (-5, 2) is in the solution set, as are points in the doubly-shaded space to its left. (-8, 4) is one of those.

__

Additional comment

The boundary lines are solid because the "or equal to" case is included in each.

The ≤ symbol tells you y-values that satisfy the first inequality will be less than (or equal to) those on the boundary line.

The ≥ symbol tells you y-values that satisfy the second inequality will be greater than (or equal to) those on the boundary line.

I get 64% off a table the sale price is $72, what is the original price?

Answers

The original price of the table was $200 before the 64% discount was applied.

What is the percentage?

Percentage is a way of expressing a fraction or proportion out of 100. It is commonly used to compare two quantities, indicate the change or growth of a quantity over time, or express the probability or chance of an event occurring.

If you received a 64% discount on the sale price of a table, and the sale price is $72, we can calculate the original price of the table as follows:

Determine the percentage of the original price that corresponds to the sale price after the discount:

If the sale price is 100% - 64% = 36% of the original price, after the 64% discount.

Use the percentage found in step 1 to calculate the original price:

Let x be the original price

x * 36% = $72

0.36x = $72

x = $72 / 0.36

x = $200

Therefore, the original price of the table was $200 before the 64% discount was applied.

For given linear equations, 27hx -9y = -18 and y = 1 - 6x

h will be 2.

What is a linear equation, exactly?

When the greatest power of a variable is 1, the equation is said to be linear. Another term for it is a one-degree equation. The standard form of a linear equation with one variable is Ax + B = 0. There are three variables in this equation: x, A, and B. A denotes a coefficient. A linear equation with only two variables is commonly written as Ax + By = C. There are three more constants in addition to the constant C: the variables x and y, the coefficients A and B, and the variables.

Now,

As general equation of a line is y=mx + c where m=slope and c=constant

and here given lines are  27hx -9y = -18 and y = 1 - 6x

transforming these into general equations

y=-3hx+2 where m=-3h

person a starts walking north at 4 ft/s from a point p. five minutes later, person b starts walking south at 5 ft/s from a point 500 feet due east of p. at what rate are the people moving apart 15 minutes after person b starts walking?

Answers

The rate at which the people are moving apart 15 minutes after person B starts walking is √2660 feet per second. To the nearest tenth of a foot per second, this is 51.3 feet per second.

Let's call the rate at which the people are moving apart "d".

15 minutes after person B starts walking, person A has been walking for 15 + 5 = 20 minutes, for a total distance of 20 * 4 = 80 feet north from point P.

At the same time, person B has been walking for 15 minutes, for a total distance of 15 * 5 = 75 feet south from point 500 feet due east of P.

The distance between the two people is the square root of the sum of the squares of their north-south and east-west separations, or:

d = √(80^2 + (500)^2) = √(80^2 + 250000) = √250100 = 500

Since the rate at which they are moving apart is the derivative of their separation with respect to time, we can find it by taking the derivative of the above equation with respect to time:

d/dt = √(2 * 80 * 4dt / dt + 2 * 500 * 5dt / dt) = √(160 + 2500) = √2660

To the nearest tenth of a foot per second, this is 51.3 feet per second.

Solve 2 ―8―33 = 0 by factoring.

Answers

Answer:

the equation 2 - 8 + 33 = 0 can be factored as 27 = 0, which is a verified answer

Step-by-step explanation:

To factor the equation 2 - 8 + 33 = 0, we start by collecting all the terms on one side of the equation:

2 - 8 + 33 = 0

becomes

33 - 8 + 2 = 0

Next, we can rewrite this as:

33 - 6 = 0

Finally, we factor the left-hand side of the equation to get:

33 - 6 = (33 - 3) - 3 = 30 - 3 = 27 - 0

So the factored form of the equation 2 - 8 + 33 = 0 is 27 = 0.

Verification: We can verify that the factored form of the equation is correct by substituting 0 for 27 and checking that the equation holds. So, if we replace 0 for 27 in equation 27 = 0, we get:

27 = 0, which is true.

Therefore, the equation 2 - 8 + 33 = 0 can be factored as 27 = 0, which is a verified answer.

What is the area of the compound figure?

The area of the compound figure given is calculated by subtracting the small area of the  figure from the big figure.

A (total) = 9 cm x 15 cm

A (total) = 135 cm²

The area of the small figure is calculated as follows;

A (small) = ( 9 cm - 4 cm ) x ( 15 cm - 5 cm )

A (small) = ( 5 cm ) x ( 10 cm )

A (small) = 50 cm²

The area of this compound figure = ( 135 cm² - 50 cm² ) = 85 cm²

En una empresa líder en investigación se quiere estimar la proporción de personas a favor de una nueva reforma política en el distrito A. ¿A cuántas personas se necesitará para la estimación, si de una muestra piloto se obtuvo que el 64. 1% de las personas están a favor de la reforma política, se desea estar seguro con un 97% de confianza y tener a lo más 4. 7% de error de estimación?

Answers

A sample of at least 870 people is needed to estimate the proportion of people in favor of the political reform in District A with a 97% confidence level and a maximum estimation error of 4.7%

To estimate the sample size, we can use the following formula:

n = (Z^2 * p * (1-p)) / E^2

where:

n = sample size

Z = the Z-score for a given confidence level (for 97% confidence, Z = 2.33)

p = the proportion in the pilot sample (0.641)

E = the maximum allowed error of estimation (0.047)

Plugging in the values, we get:

n = (2.33^2 * 0.641 * (1 - 0.641)) / 0.047^2

n = (5.3929 * 0.359) / 0.00222009

n = 1.928 / 0.00222009

n = 869.75

Since the sample size must be a whole number, we round up to the nearest whole number.

n = 870

Therefore, a sample of at least 870 people is needed to estimate the proportion of people in favor of the political reform in District A with a 97% confidence level and a maximum estimation error of 4.7%

over the course of a year, malachi gets 2 haircuts at a price of $12.00 each, 3 haircuts at a price of $15.00 each, and 1 haircut at a price of $25.00. for malachi,what is the weighted mean cost of a haircut?

Answers

The weighted mean cost of a haircut for Malachi is $15.67, divided by the total number of haircuts, which comes to 6, to yield a total cost of $94.00.

We must compute the total cost of all haircuts and divide it by the total number of haircuts in order to determine the weighted mean price of a haircut for Malachi. The expense of each haircut must be weighed according to the frequency with which it occurred, though, because they varied in price.

To begin, let's figure out how much each haircut will cost overall:

2 haircuts at $12.00 each = $24.00

3 haircuts at $15.00 each = $45.00

1 haircut at $25.00 = $25.00

Total cost = $24.00 + $45.00 + $25.00 = $94.00

Next, We must determine the total number of cuts:

2 haircuts + 3 haircuts + 1 haircut = 6 haircuts

Finally, The weighted mean cost of a haircut can be determined by dividing the total cost by the total number of haircuts:

The weighted mean cost of a haircut = Total cost / Total number of haircuts

= $94.00 / 6 haircuts

= $15.67 per haircut (rounded to the nearest cent)

Therefore, Malachi's weighted mean haircut expense is $ 15.67 , divided by the total number of haircuts, which comes to 6, to yield a total cost of $94.00.

What is the kinetic energy of a 3 kg ball that is rolling at 2 m/s

Answers

The kinetic energy of the 3 kg ball rolling at 2 m/s is 6 joules. The kinetic energy of an object is the energy it possesses due to its motion.

The kinetic energy of an object is the energy it possesses due to its motion. The formula for kinetic energy is given by:

Kinetic Energy = (1/2) * mass * velocity^2

In this case, the mass of the ball is 3 kg and its velocity is 2 m/s, so we can plug these values into the formula:

Kinetic Energy = [tex](1/2) * 3 kg * (2 m/s)^2[/tex]

Kinetic Energy = [tex](1/2) * 3 kg * 4 m^2/s^2[/tex]

Kinetic Energy = 6 J

So the kinetic energy of the 3 kg ball rolling at 2 m/s is 6 joules.
