A jar contains only​ pennies, nickels,​ dimes, and quarters. There are 14 ​pennies, 28 ​dimes, and 16 quarters. The rest of the coins are nickels. There are 70 coins in all. How many of the coins are not​ nickels? If n represents the number of nickels in the​ jar, what equation could you use to find​ n?

Answers

Answer 1
Answer:

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

What is the area of a circle with a radius of 1 foot?

Answers

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

How to find cos(-19pi/6)

Answers

Use the unit circle.

-19pi/6 is the same as 3pi + pi/6
This means that it goes around the unit circle 3pi times and ends up at 7pi/6

So -19pi/6 is equivalent to 7pi/6.

Looking at the unit circle, cos(7pi/6) = -√3/2
