The floor of a round hut has a diameter of 4 yards. What is the floor's area?

Answer:

x = 20

Step-by-step explanation:

Corresponding angles are congruent (have the same measurements).

5x + 15 = 115  Subtract 15 from both sides

5x + 15- 15 = 115 - 15

5x = 100   Divide both sides by 5

x = 20

Answer:

22

Step-by-step explanation:

Range : Maximum - Minimum

Minimum = 6

Maximum = A (Let maximum be A)

Hence,

16 = A - 6

A = 22

Maximum = 22

The value of x on the diagram is given by the following option:

D) 50º.

When two parallel lines are cut by a transversal line, the corresponding angles are the angles that are in the equivalent position for each parallel line.

The parallel lines for this problem are given as follows:

L1 and L2.

Hence the corresponding angles are given as follows:

The bases of the rectangle are also parallel, hence two extra pairs of corresponding angles are given as follows:

As all these angles are corresponding, they have the same measure, hence:

4a = 100º

a = 100º/4

a = 25º.

The angle x is twice the measure of these angles, hence:

x = 2 x 25º

x = 50º.

Meaning that option D is correct.

The number of children and adults that swan at the public pool that day would be = 208 and 209 respectively.

The number of people that swam on the summer day = 485 people.

The price paid for children = $1.25

The price paid for adults = $2.00

The total amount of money paid for the admission = $677.50.

The amount paid only for adults;

= 2/2+1.25 × 677.50/1

= 1355/3.25

= $416.92

The number of adults that swam ;

= 416.92/2

= 208.46

= 209 (approximately).

The amount paid for children;

= 1.25/3.25 × 677.50/1

= 846.875/3.25

= $260.58

The number paid for children alone;

Answer:

Step-by-step explanation:

Given-: Y= -X+1  (1)

            3X-Y=3  (2)

we will put the value of Y from equation (1) in equation (2)

  3X-(-X+1)=3

   3X+X-1=3

   4X-1=3

Taking -1 to R.H.S

  4X=3+1

 4X=4

 X=4/4

 X=1

Now put the value of X in equation (1)

Y=-X+1

Y=-1+1

Y=0

So the option will be B (1,0)

Answer: The inequality that can be used to determine the maximum number of days Alyssa can afford to rent for while staying within her budget is:

43d + 0.1(275) <= 100

Step-by-step explanation: The rental car company charges $43 per day to rent a car and $0.10 for every mile driven.

Alyssa wants to rent a car for d days, and she plans to drive 275 miles.

The cost of renting the car for d days is 43d, and the cost of driving 275 miles is 0.1(275)

To determine the maximum number of days Alyssa can afford to rent for while staying within her budget, we can write the inequality:

43d + 0.1(275) <= 100

This inequality represents the total cost of renting the car and the cost of driving, which should be less than or equal to $100 (Alyssa's budget)

On solving the inequality we can determine the maximum days Alyssa can afford.

Step-by-step explanation:

Using the decay constant on the exponential function, the mass of the sample that will be left in 2013 is 35g

An exponential function is a function that can be expressed in the form     f(x) = b^x, where b is a positive real number and x is a real number. The graph of an exponential function is a curve that increases or decreases rapidly as x increases or decreases.

In the exponential decay, the decay function can be given as;

y = ae⁻ⁿˣ

The disintegration constant is also know as the rate of decay and we can calculate it as;

260 = 470e⁻ⁿ⁽³⁾

n = 0.197

n = 0.2

The disintegration constant is 0.2

The amount left in 2013 will be;

y = 470e⁻⁽⁰.²⁾⁽¹³⁾

y = 34.90

Answer:

To solve this problem, we will use the following steps:

Step 1: Let's assume that the number of adult tickets sold is x and the number of senior/child tickets sold is y

Step 2: We know that the number of senior/child tickets sold was 27 less than twice the number of adult tickets sold, so we can write the equation: y = 2x - 27

Step 3: We also know that the total value of tickets sold was $2,647.50. Since adult tickets sold for $10 each and senior/child tickets sold for $7.50 each, we can write the equation: 10x + 7.5y = 2,647.50

Step 4: Now we have two equations with two unknowns, we can substitute one equation into another to find the value of x and y.

y = 2x - 27

10x + 7.5(2x - 27) = 2,647.50

10x + 15x - 405 = 2,647.50

25x = 3,052.50

x = 122

Step 5: We can substitute the value of x in one of the equation, to find the value of y

y = 2(122) - 27

y = 245

Final Answer: 122 adult tickets and 245 senior/child tickets were sold.

Note: We can check our solution by multiplying the number of adult tickets by $10 and the number of senior/child tickets by $7.5 to check if the total money is $2,647.50 which is true.

Step-by-step explanation:

Given a table of ages and weights, you want the average rate of change (per month) for consecutive pairs of table values.

The average rate of change is the change in weight divided by the change in age. For example, in the interval 0–6 months, it is ...

  (17.4 -7.8)/(6 -0) = 9.6/6 = 1.6 . . . . . pounds per month

The calculations are conveniently done for the rest of the table by a spreadsheet. The results are attached. The value on each line is the average over the interval from that age to the next.

Answer: The function f(x) = || is the absolute value function of x, which is defined as f(x) = |x|. The graph of this function is a "V" shape, with the vertex at the origin (0,0) and the lines x = 0 and y = 0 as the asymptotes. The graph of f(x) starts at the origin and increases as x increases or decreases, but never reaches x-axis.

The function g(r) = (-1)|r| is the absolute value function of r, multiplied by -1. The effect of multiplying the function by -1 is to reflect the graph of f(x) across the x-axis. So the graph of g(r) will be a "V" shape, with the vertex at the origin, and the lines x = 0 and y = 0 as the asymptotes. The graph of g(r) starts at the origin and decreases as r increases or decreases, but never reaches x-axis.

In summary, the effect of the change on the graph of f(x) = || is that it will be reflected across the x-axis.

The equation is solved and the values of a and b is simplified as

a) The possible values of ab = 4

b) The possible values of a + b = 4

c) The possible values of a and b = 2

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

(a)

To find all possible values of ab, we can use the identity:

a⁴ + b⁴ = (a² + b²)² - 2a²b²

Substituting the given values, we have:

16 = (a² + b²)² - 2a²b²

We also know that a + b=4, which means that b = 4 - a.

Substituting this into the equation above, we have:

16 = (a² + (4-a)²)² - 2a²(4-a)²

Simplifying, we get:

16 = (2a² - 8a + 16)² - 32a² + 64a³ - 32a⁴

Expanding, we get:

16 = 4a⁴ - 64a³ + 288a² - 512a + 272

Rearranging and factoring, we get:

4a⁴ - 64a³ + 288a² - 512a + 256 = 0

Dividing by 4, we get:

a⁴ - 16a³ + 72a² - 128a + 64 = 0

This is a quartic equation, which can be factored as:

(a-2)⁴ = 0

Therefore, the only possible value of a is 2, which means that the only possible value of b is 2 as well.

So, ab = 2 x 2 = 4

(b)

We know that a + b = 4, and since a = 2, we have b = 4 - a = 2

Therefore, the only possible value of a + b is 4

(c)

From part (b), we know that the only possible value of a + b is 4. From part (a), we know that the only possible values of a and b are both equal to 2.

Therefore, the only possible solution is a = 2 and b = 2

Answer:

you could fit 7776 people on the gym floor for an event.

Step-by-step explanation:

The Locust Grove gymnasium has an area of 54 yd x 40 yd = 2160 square yards. To find the number of people that can fit on the gym floor, we need to convert the area of the gym floor to square feet and divide it by the number of square feet each person takes up.

We know that 1 yard = 3 feet, so we have to convert the area of the gymnasium in square yards to square feet by multiplying it by (3*3) = 9.

So the area of the gymnasium in square feet is 2160*9 = 19440 square feet.

To find the number of people that can fit on the gym floor, we divide the area of the gym floor by the number of square feet each person takes up.

19440 square feet / 2.5 square feet/person = 7776 people
