Answer:

4

Step-by-step explanation:

Sum and Divide

Answer: 4

Step-by-step explanation:

First we need to find the difference of the balance.

it was -80 then it became -44. The difference is 36.

Next we divide 36 by 9 from the 9 parents.

The answer is 4

Answer:

X= -5

Step-by-step explanation:

Good luck!

Answer:

X=-5

Step-by-step explanation:

100 + 84 - 62x =494

184 - 62x =494

494-184 = -62x

310 =-62x

310/-62 =x

X= -5

Answer:

x = 5

Step-by-step explanation:

x² + (2x+2)² = (2x+3)²

x² + 4x² + 8x + 4 = 4x² + 12x + 9

x² - 4x - 5 = 0

(x - 5)(x + 1) = 0

x = -1  This can be discounted as the answer because you cannot have a negative length

answer: x = 5

Answer:

8.0meters

Step-by-step explanation:

Given data

Area of cirlce= 201 square meters

The expression for the area is

A=πr^2

Substitute our area

201= 3.14*r^2

r^2= 201/3.14

r^2= 64.01

square both sides

r= √64.01

r= 8.0 meters

Hence the radius is 8.0meters

Answer:

$18.75

Step-by-step explanation:

Determine the total hours worked by both individuals = 2.5 + 4 = 6.5 hours

Determine the fraction of hours that Eric worked = 2.5/6.5 = 0.384615

Multiply this fraction by the total amount earned = 0.384615 x $48.75 = $18.75

Answer:

192

Step-by-step explanation:

This is because its a square and all the sides on a square are equal so it would be:

top/bottom= 8*8

left/ right= 8*8

front/ back= 8*8

all equal 64 then you do 64*64*64 to get 192!

Answer:

d= 2√a/π

To calculate the diameter, rewrite the formula to isolate D

Because a negative diameter doesn’t make sense, eliminate the negative answer from the solution

Simplify further to get the solution

The formula to calculate the diameter of the circle is d = 2 √( A/π )

where d = diameter of the circle

A = area of the circle

What is a Circle?

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle

The perimeter of circle = 2πr

The area of the circle = πr²

where r is the radius of the circle

The standard form of a circle is

( x - h )² + ( y - k )² = r²,

where r is the radius of the circle and (h,k) is the center of the circle

Given data ,

Let the radius of the circle be = r

So , the diameter of the circle = 2r

Now , the area of the circle = πr²

Substituting the value for r , we get

Area of the circle = ( 1/4 ) πd²

So , A = ( 1/4 ) πd²

Now , solving the equation for diameter of circle d , we get

Multiply by 4 on both sides of the equation , we get

πd² = 4A

Divide by π on both sides of the equation , we get

d² = 4A/π

Taking square roots on both sides of the equation , we get

d = 2 √A/π

Therefore , the value of d is 2 √A/π

Hence ,

The formula to calculate the diameter of the circle is d = 2 √( A/π )

where d = diameter of the circle

A = area of the circle

Answer:

(72.5,87.5)

Step-by-step explanation:

The interval of times that represents the middle 99.7% of his finishing times in the 400 meter race is; (73.5, 87.5)

We are given;

Mean; E(X) = μ = 80 seconds

Standard Deviation; σ = 2.5

From the empirical rule, the probability of obtaining values within one deviation from the mean is 0.68; within two deviations is 0.95 and within 3 deviations from the mean is 0.997.

We have 99.7 % of the values within 3 deviations from the mean in our question and so the intervals are;

μ - 3σ = 80 - 3(2.5) = 73.5

μ + 3σ = 80 + 3(2.5) = 87.5
