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.

Answer:

120°

Step-by-step explanation:

The two angles are alternate angles and has same measurement.

Answer:

Dimensions are:

Length = 4 ; width = 10

or

Length = 10 ; width = 4

Step-by-step explanation:

let the length = L

let the width = W

we are given the following:

area of rectangle = L × W = 40 m² - - - - - - ( 1 )

perimeter of a rectangle = 2L + 2W = 28 m - - - - - ( 2 )

from equation (2)

2L + 2W = 28

2L = 28 - 2W

dividing both sides by 2

(2L = 28 - 2W) ÷ 2

L = 14 - W  - - - - - - (3)

Next, let us replace the value of L in equation 1 with equation 3

L × W = 40 - - - - (1)

where L = 14 - W

(14 - W) × W = 40

14W - W²  = 40

0 = W² - 14W + 40

solving the quadratic equation

using completing the squares method

W² - 14W + 40

W² [-4W - 10W] + 40 =  0

(W² - 4W) - (10W + 40) = 0

W(W - 4) - 10(W - 4) = 0

W - 10 = 0; ∴ W = 10

or

W - 4 = 0 ;  ∴ W = 4

putting the values of W into equation (3)

L = 14 - W

where W = 10 or 4

L = 14 - 10 = 4

or L = 14 - 4 = 10

∴ Dimensions are:

Length = 4 ; width = 10

or

Length = 10 ; width = 4

Answer:

2.215=2 43/200

Step-by-step explanation:

Showing the work

Rewrite the decimal number as a fraction with 1 in the denominator

2.215=2.215/1

Multiply to remove 3 decimal places. Here, you multiply top and bottom by 103 = 1000

2.215/1×1000/1000=2215/1000

Find the Greatest Common Factor (GCF) of 2215 and 1000, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 5,

2215÷5/1000÷5=443/200

Simplify the improper fraction,

=2 43/200

In conclusion,

2.215=2 43/200

Answer:

[tex]\frac{731}{330}[/tex]

Step-by-step explanation:

We require 2 equations with the repeating numbers placed after the decimal point.

let x = 2.2151515... ( multiply both sides by 10 and 1000 )

10x = 22.1515.... → (1)

1000x = 2215.1515.... → (2)

Subtract (1) from (2) thus eliminating the repeating decimal

990x = 2193 ( divide both sides by 990 )

x = [tex]\frac{2193}{990}[/tex] = [tex]\frac{731}{330}[/tex]

Thus

2.2151515..... = [tex]\frac{731}{330}[/tex]

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.

Answer:

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:

Answer is C

Step-by-step explanation:

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.
