Answer:
Step-by-step explanation:
Let n represent the number of nickels in the jar.
The jar contains only pennies, nickels, dimes, and quarters. There are 14 pennies, 28 dimes, and 16 quarters. This means that the total number if pennies, dimes and quarters would be
14 + 28 + 16 = 58
This means that the number of coins that are not nickel is 58
The total number of coins in the jar is 70. Therefore, the equation that can be used to find n is
n + 58 = 70
n = 70 - 58
n = 12 nickels
B. 1 12⁄7
C. 1 7⁄12
D. 7 1⁄2
two places to the left
B.
two places to the right
C.
three places to the left
D.
three places to the right
your answer would be C, cause 1,000 has three zeros;
60.8 ÷ 1,000 = 0.0608
The answer is 3 places to the left
Answer:
3.14 ft² or 2,917 cm²
Step-by-step explanation:
To do this, we need to know the expression to calculate the area of a circle.
The area of any circle is:
A = πr²
Where:
π: value of pi, which is 3.14
r: radius of the circle, in this case 1 ft
Calculating the area in units of ft:
A = 3.14 * (1)²
A = 3.14 ft²
Now, if you convert the foot to cm we have:
1 * 30.48 = 30.48 cm
Solvinf for A:
A = 3.14 * (30.48)²
A = 2,917.15 cm²
Answer:
Pi feet squared
