A parallelogram is a _____ polygon in which both pairs of opposite sides are parallel.

Answer: 16%

Step-by-step explanation: If 80% of customers purchased regular gas and 10% of those who purchased regular gas paid in cash, then 8% paid in cash. If 100-80=20% of customers purchased something other than regular gas and 40% of those who did paid in cash, than another 8% paid in cash. 8+8=16, so (c 16 is the answer.

Step-by-step explanation:

1) 2t + 5t + 2 = 0

Add 2t + 5t = (2+5)t = 7t

7t + 2 = 0

Substract 2 from both sides

7t + 2 - 2 = 0 - 2

7t = -2

Divide both sides by 7

7t/7 = -2/7

9−36x=36x2

Step 1: Simplify both sides of the equation.

−36x+9=36x2

Step 2: Subtract 36x^2 from both sides.

−36x+9−36x2=36x2−36x2

−36x2−36x+9=0

For this equation: a=-36, b=-36, c=9

−36x2+−36x+9=0

Step 3: Use quadratic formula with a=-36, b=-36, c=9.

Answer:

Equation 1: (500×5)+75

Equation 2: (20×5)×7

Total Revenue: $1,875

Step-by-step explanation:

For equation 1 we multiply the companys $500 an hour flat rate by the number of hours the party was (5), then add the company's $75 set up fee for a total of $2,575.

For equation 2 we multiply the company's hourly pay (20) by the number of hours worked (5), after that we multiply the number of employees (7) for a total of $700.

Finally to figure out the actual revenue from the event we subtract the amount the company paid the employees ($700) from the total paycheck for hosting the party ($2,575) for a final total of $1,875.

In arithmetic, a chain is an enumerated series of gadgets in which repetitions are allowed and order matters. Like a hard and fast, it consists of contributors (additionally referred to as elements, or terms). The quantity of elements (possibly endless) is called the duration of the series.

Unlike a fixed, the same factors can appear a couple of times at distinct positions in a chain, and unlike a fixed, the order does be counted. formally, a chain can be described as a function from herbal numbers (the positions of elements inside the collection) to the factors at each position.

For x^2 * 5x to end in 5, x must be an odd number.

The last digit of a number is determined by its units digit. For example, the last digit of 123 is 3, the last digit of 789 is 9, and so on.

When you multiply two numbers, the last digit of the product is determined by the last digit of each factor. For example, the last digit of 3 * 4 is 2, the last digit of 6 * 7 is 2, and so on.

In this case, x^2 * 5x is a product of two numbers, x^2 and 5x. To find the units digit of x^2, we can square the units digit of x. The units digit of 5x is the units digit of x.

So, since we want x^2 * 5x to end in 5 , the last digit of x^2 * 5x has to be 5. The last digit of x^2 is the square of the last digit of x, and the last digit of 5x is 5 if x is odd and 0 if x is even.

Answer:

The point is in the second quadrant.

Substitute 6 for r.

The value of y is approximately 5.196.

Step-by-step explanation:

To convert polar coordinates (r,θ) to rectangular coordinates (x,y), we use the following formulas:

x = r * cos(θ)

y = r * sin(θ)

The point is in the second quadrant.

-This statement is true because the polar angle (120°) is in the range of 90° < θ < 180° which correspond to the second quadrant in the cartesian plane.

Start by adding 180° to θ.

This statement is False, because when converting from polar coordinates to rectangular coordinates we don't need to add 180° to the angle, we use the given angle as it is.

Substitute 6 for r.

This statement is true. In this case, the given polar coordinates are (6, 120°), so we substitute 6 for r in the formulas.

The value of x is 3.

This statement is False, to calculate x we use the formula x = r * cos(θ), so in this case x = 6 * cos(120°) = -3, which is not equal to 3.

The value of y is approximately 5.196.

This statement is true, to calculate y we use the formula y = r * sin(θ), so in this case y = 6 * sin(120°) = 6 * 0.866 = 5.196, which is approximately equal to 5.196

The multiplication rule example is calculating the probability that both the balls drawn are red from an urn containing 30 red and 10 blue balls. Two balls are pulled from a bag one after the other without replacement.

As per the multiplication rule, the probability of events A and B happening is equal to the product of the probability of B happening and the conditional probability that event A happens if event B occurs.

If A and B are dependent events, then the probability of both events happening simultaneously is given by:

P(A ∩ B) = P(B).P(A|B)

If A and B are two independent events in an experiment, then the probability of both events happening simultaneously is given by:

P(A ∩ B) = P(A).P(B)

Let's solve our given example

Let A and B represent the events that the first and the second balls are pulled, which are red balls. Now, we have to calculate P(A∩B) or P(AB).

P(A) = P(red balls in first draw) = 30/40

Now, only 10 balls of blue colour and 29 balls of red colour are left in the bag. The probability of pulling a red ball in the second draw is also an example of conditional probability, where the drawing of the second ball depends on the drawing of the first ball.

Hence Conditional probability of B on A will be,

P(B|A) = 29/39

By multiplication rule of probability,

P(A∩B) = P(A) × P(B|A)

P(A ∩ B) = 30/40 × 29/39 = 29/52

The number that should be added to the expression x²+4x to change it into a perfect square trinomial is 4.

The general form of a perfect square trinomial is (x + y)^2, where x and y are the roots of the trinomial. To check if a trinomial is a perfect square, we can try to factor it into the square of a binomial. We can also complete the square method, which involves adding and subtracting the square of half of the x-coefficient of the linear term and then grouping the resulting terms.

It is important to note that for a trinomial to be a perfect square trinomial, the constant term must be a square of an integer and the linear term must be an even number.

Answer: Goran will run at most 27 miles this week, and he has already run 13 miles, so the number of additional miles he will run is given by the difference of 27 - 13 = T.

Therefore, T = 27 - 13 = 14 miles

We can express this as an inequality:

T <= 14

This inequality represents that T, the number of additional miles he will run, can be any number less than or equal to 14.

Another way to express this is T <= 27-13

So the possible numbers of additional miles he will run are T <= 14.

For the equation -6x + 3y = -7 , the x-intercept and y-intercept is obtained as (1.167,0) and (0,-2.333) respectively.

What is an equation?

A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").

The given equation is -

-6x + 3y = -7

To find the x-intercept, substitute the value of y = 0.

-6x + 3(0) = -7

-6x + 0 = -7

-6x = -7

Use the arithmetic operation of division -

x = -7/-6

x = 1.167

To find the y-intercept, substitute the value of x = 0.

-6(0) + 3y = -7

0 + 3y = -7

3y = -7

Use the arithmetic operation of division -

y = -7/3

y = -2.333

So, the x-intercept is obtained as x = 1.167 and y-intercept is obtained as  y = -2.333.

A graph can also be plotted to find the intercepts.

Therefore, the intercepts are x = 1.167 and y = -2.333.

To determine the value of an unknown variable that represents an unknown quantity, equations can be solved. The statement is not an equation if there is no "equal to" sign in it.

Equations can be divided into three categories based on their degree. The three categories of mathematical equations are as follows:

Linear Equations

Quadratic Equations

Cubic Equations

Pedro's Elevation in feet equation

E = 4200 - 800h

So, initial elevation at h = 0 is

E = 4200 ft for Pedro

Now Naomi's Initial Elevation is 3500 ft.      

So, Pedro is 4200 - 3500 = 700 ft higher than Naomi                                            

at h = 1hr

Pedro's Elevation = 4200 - 800*1 = 3400 ft

and Naomi's Elevation = 2900 ft

Speed of desending of Pedro is = total distance/ total time

= (4200 - 3400)/1 = 800 ft/hr

Speed of desending of Naomi is = total distance/ total time

(3500 - 2900)/1 = 600 ft/hr

For Elevation = 0 for Pedro

0 = 4200 - 800h

h = 4200/800 = 5.25 hr
