Answer:

Unit rates are expressed as a quantity of 1, such as 3 feet per second or 6 miles per hour, they are called unit rates.

In the given table shows the number of pictures taken and how much time it took.

For first camera;

Number of pictures (unit rate) per second = \frac{15}{3} =5 pictures.

For second Camera:

Number of picture per second = \frac{48}{8} =6 pictures.

For third Camera:

Number of picture per second = \frac{18}{6} =3 pictures.

The camera that takes picture the fastest is, Second Camera.

(a)

As per the given statement: At Davidson's Bike rentals, it costs $29 to rent a bike for 8 hour.

⇒ unit rate per dollar = \frac{Number of hours }{Total cost} = \frac{8}{29} = 0.2758620 hours

Therefore, 0.227 hours (nearest to hundredths) of bike use does a customer get per dollar.

(b)

Jessica bought 18 pounds of sugar for $10.

unit rate per dollar = \frac{18}{10} =1.8 pounds

therefore, 1.8 pounds of sugar did she get per dollar.

130 apples at the party. There were 3 times as many yellow apples as green apples, there were twice as many red apples as yellow
kipiarov [429]

Answer: There were 78 red apples at the party.

Step-by-step explanation:

This situation can be represented by the equation  

x + 3x + 2(3x) = 130    where x is the number of green apples, 3x is the number of  yellow apples and 2(3x) is the number  of red apples.

Now solve for x

x +3x +2(3x) =130

4x + 6x = 130

10x  = 130

x =  13  

Now we know that x is 13 so put it into the expression for red apples and solve for the actual number of red apples.

2 * (3*13)  = ?

2 * 39 = 78
