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.

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]

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:

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.

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:

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.
