Answer:

The answer is C because how much each girl paid for each pound of cherries has the variable C attached, and the rest of the money spent added to it. Also looking in the equation the sign tells us that they paid the same price for everything totaled in all.

Kevin and Randy Muise have a jar containing 41 coins, all of which are either quarters or nickels. The total value of the coins

Aleks [24]

Answer:

There are 27 quarters and 14 nickles

Step-by-step explanation:

Step 1: Make a system of equations

n + q = 41

0.05n + 0.25q = 7.45

Step 2: Solve for n in the first equation

n + q - q = 41 - q

n = 41 - q

Step 3: Plug in n into the second equation

0.05(41 - q) + 0.25q = 7.45

2.05 - 0.05q + 0.25q - 2.05 = 7.45 - 2.05

0.2q / 0.2 = 5.4 / 0.2

q = 27

Step 4: Find the amount of nickels

n = 41 - 27

n = 14

Answer: There are 27 quarters and 14 nickles

PLEASE HELP The following table gives the heights and weights of 10 friends

ohaa [14]

Graph is attached.

Based on the graph (with height on the independent axis and weight on the dependent), there is a negative correlation between height and weight; as the height increases, the weight decreases.

If we were to graph this with weight on the independent axis and height on the dependent, there would still be a negative correlation.

9 m 3 m 3 m What is the area, in square meters, of the shaded region in the diagram?

NeTakaya

Answer:

Notice that the side length of the square is 38 m.

area of square = (side length)2 = (38 m)2 = 1444 m2

Notice that the diameter of the circle is 38 m .

And its radius = diameter / 2 = 38m / 2 = 19 m

area of circle = pi * radius2 = pi * (19m)2 = pi * 361 m2 ≈ 1133.54 m2

So......

area of shaded region = area of square - area of circle

area of shaded region ≈ 1444 m2 - 1133.54 m2

area of shaded region ≈ 310.46 m2

Step-by-step explanation:

Notice that the side length of the square is 38 m.

area of square = (side length)2 = (38 m)2 = 1444 m2

Notice that the diameter of the circle is 38 m .

And its radius = diameter / 2 = 38m / 2 = 19 m

area of circle = pi * radius2 = pi * (19m)2 = pi * 361 m2 ≈ 1133.54 m2

So......

area of shaded region = area of square - area of circle

area of shaded region ≈ 1444 m2 - 1133.54 m2

area of shaded region ≈ 310.46 m2
