Option (3)

Step-by-step explanation:

Area of a circle is given by the formula,

Area = πr²

Here, r = radius of the circle

Since, radius of the circular trampoline = 8 feet

Area of the cover required for the circular trampoline = π(8)²

                                                                                         = 64π square feet

Therefore, Option (3) will be the answer.

Answer:

B)
A, B, and E.

Answer:

1. The y-intercept 8 means you start off with $8. The slope 1/4 means how much money you have to pay for the amount of tickets purchased for carnival games.

2. The y-intercept 2 means the number of chapters you started reading and the slope 5/4 means the number of chapters you read per day.

3. The y-intercept 3 means the inital (start) cost of a muffin delivery and the slope 2 means the cost of each muffin delivery for the number of muffins you ordered.

Number 3 on the slope part might be the other way around if I'm wrong :)

Answer:

to find the sons shadow you would simply multiply the length of his body by 2, therefore his shadow would be 2 meters long

The height of shadow is 2 meter long.

We have,

The father is 2 meters tall and casts a shadow 4 meters long.

let the length of shadow be x.

Using proportion

2/4 = 1/ x

2x = 4

x =4 /2

x = 2 meter

Thus, the height is 2 meter tall.

Answer: 1/12 of the box

Step-by-step explanation:

On Monday the dog ate 3/12 of the treats in the box and on Tuesday ate 2/12 of the treats in the box.

The answer to this question is the difference between both these fractions:

= 3/12 - 2/12

= 1/12 of the box

Answer:

-12

Step-by-step explanation:

2n - 6 = -30

Add both 6 on each side

2n - 6 + 6 = -30 + 6

2n = -24

Divide 2 on both sides

Answer: 10 CD's

Step-by-step explanation:

Given

Tom can  burn a CD in  [tex]\frac{4}{5}\ \text{of an hour}[/tex]

If he has 8 spare hours in the week, he can burn

[tex]\Rightarrow 8\div \frac{4}{5}=\dfrac{8}{\frac{4}{5}}\\\Rightarrow \dfrac{8\times 5}{4}=2\times 5=10\ \text{CD}[/tex]

R=8ft

Step-by-step explanation:

Calculate r using the given formula

r = , with Area = 64π

r = ← cancel π on numerator/ denominator

r = = 8

The required value of radius of circle r is 8 ft

From Figure the area of circle is = 64π, we have to find the radius of the circle.

Area of the circle is = π[tex]r^2[/tex]

since

the area of the circle is given = 64π

And,
Radius = √area/π
radius= √64π/π
Radius = √64
Radius = 8 ft

Thus The required value of radius of circle r is 8 ft.

Step-by-step explanation:

Given :

Let, capacity of small bottle is x and large bottle is y.

To Find :

How much does each bottle hold ?

Solution :

For condition 1 :

3x + 4y = 3312   ...1)

For condition 2 :

2x + 4y = 2888  ...2)

Subtracting equation 2) from equation 1), we get :

x = 424

Putting value of x in equation 1) is :

[tex]y = \dfrac{2888 - (2\times 424)}{4}\\\\y = 510[/tex]

Therefore, capacity of small bottle is 424 gram and large bottle is 510 gram.
