Answer:

The multiplicative inverse of 7 is 1/7

Step-by-step explanation:

A reciprocal is one of a pair of numbers that when multiplied with another number equals the number 1. For example, if you have the number 7, the multiplicative inverse, or reciprocal, would be 1/7 because when you multiply 7 and 1/7 together, you get 1.

A straight line is 180°.

The sum of all the angles in a triangle is also 180°.

Let the missing angle be x°.

For the straight line:
x + 2x²+ 3x+ 6 = 180

x = 180 - (2x² + 3x + 6)

x = 180 - 2x² - 3x - 6

x = 174 - 2x² - 3x

For the missing angle in the triangle:
(174 - 2x² - 3x) + 8x + 3x² - 6x = 180

174 - 2x² - 3x + 8x + 3x² - 6x = 180

174 + x² - x = 180

x² - x + 174 - 180 = 0

x² - x - 6 = 0

(x + 2)(x - 3) = 0

x + 2 = 0 or x - 3 = 0
x = -2 or x = 3


The answer is x = -2 or x = 3

you have 4500 cubic centimeters of wax. how many cylindrical candles can you make from the wax if each candle is 15 cm tall and
ira [324]
Use the formula for the volume of a cylinder to work out how much wax you need to make one candle.

π×5²×15 = 375π

Then divide the amount of wax you have by the amount of wax you need to produce one candle to work out how many candles you can make.

4500 ÷ 375π = 3.82

However, you can't produce 82% of a candle, so you have to round down to 3 candles.
