Answer:
The answer is 51
Step-by-step explanation:
p +d = 74 coins
rewrite as p =74-d
0.01p + 0.10d = 4.61
0.01(74-d) +0.10d = 4.61
0.74 - 0.01d +0.10d =4.61
0.74 +0.09d =4.61
0.09d = 3.87
d = 3.87/.09 = 43
p = 74-43 = 31
43 dimes and 31 pennies

Answer:
9.42 cubic inches
Step-by-step explanation:
In order to find the volume for a sphere, we use the formula V = πr. For the sake of simplicity, we will be using 3.14 for π. Before we plug anything in, let's get our radius. Remember, the radius is half of the diameter.
Equation: d = 2r
Replace: 6 = 2r
Divide: 3 = r
Now that we have our radius, let's plug in what we have and solve.
Equation: V = 3.14r
Replace: V = 3.14(3)
Multiply: V = 9.42
Remember, volume is measured in cubic units, so use cubic inches for the unit here.
