m<1 + m<O + m<P = 180°

m<1 + 70° + 38° = 180°

m<1 + 108° = 180°

m<1 = 72°

Due to a bad crop year, the cost of cherries is projected to increase 133% this year. A pound of cherries currently costs $2.16.

aliya0001 [1]

To solve this problem, or one of sorts, you can multiply the current price (2.16) by 1.33 (the percentage as a decimal).

2.16*1.33 = 2.8728

Round to two decimal places (and that’s the number of decimal places for money), and you can expect the new price per pound of cherries to be about $2.87.

How did the temperature change if: at first it decreased by 60% and then increased by 80%. PLEASE NEED HELP!

Sergio039 [100]

The temperature decreased by 28%

Step-by-step explanation:

How did the temperature change if :

At first it decreased by 60%
Then increased by 80%

Assume that the temperature before decreasing is 100%

∵ The temperature before decreasing = 100%

∵ It decreased by 60%

→ Before decreasing : decreasing : after decreasing

→ 100% : 60% : 100% - 60% = 40%

∴ The temperature after decreasing = 40%

Assume that the temperature after decreasing is 100%

∵ The temperature after decreasing = 100%

∵ It increased by 80%

By using the ratio method

→ After decreasing : increasing : after increasing

→ 100% : 80% : 100% + 80% = 180%

→ 40% : : x%

By using cross multiplication

∴ 100% × x% = 40% × 180%

- Divide both sides by 100%

∴ x% = $\frac{(40)(180)}{100}$

∴ x% = 72%

∵ At first the temperature = 100%

∵ At last the temperature = 72%

∵ The first the temperature > the last the temperature

∴ The decreasing in temperature = 100% - 72% = 28%

The temperature decreased by 28%
