A model car is 8 inches long and 5.2

Sphinxa [80]

Use proportions here - 8/5.2 = 96/width of actual car. using cross multiplication, 5.2*96 = 8x. this gives you 499.2 = 8x. divide both sides by eight to get x=62.4. the width of the actual car is 62.4 inches.

Joy is making a fruit salad. For every 2 cups of blueberries that Joy uses in the fruit salad, she uses 3 cups of strawberries.

Igoryamba

Joy will need to use 9 cups of strawberries for 6 cups of blueberries.

Step-by-step explanation:

Given,

Cups of blueberries used for 3 cups of strawberry = 2

Ratio of cups of blueberry to strawberry = 2:3

Joy wants to use 6 cups of blueberries.

Let,

x be the cups of strawberry for 6 cups of blueberries.

Ratio of cups of blueberries to strawberries = 6:x

Using proportion;

Ratio of cups of blueberry to strawberry :: Ratio of cups of blueberries to strawberries

$2:3::6:x$

Product of extreme = Product of mean

$2*x=3*6\\2x=18$

Dividing both sides by 2

$\frac{2x}{2}=\frac{18}{2}\\x=9$

Joy will need to use 9 cups of strawberries for 6 cups of blueberries.

The position function for the movement of a particle is given by s=(t^3+1)^2 where s is measure in feet and t is measured in sec

Ray Of Light [21]

Answer:

The position of particle at 1 second is 4 feet.

Step-by-step explanation:

We are given the following in the question:

$s(t)=(t^3+1)^2$

where s is a position function and measure in feet and t is measured in seconds.

We have to evaluate the position at 1 second.

Putting t = 1 in the position function, we get.

$s(1)=((1)^3+1)^2\\s(1) = 4$

Thus, the position of particle at 1 second is 4 feet.
