## Answers

You have to do X to the power of two times X to the power of four and multiply that by itself and then multiply X to the power of 2+4 by itself to find the X

Expression Katrina drinks of water in 7 day = 8 *7 cups .

Step-by-step explanation:

Given : Katrina drinks 0.5 gallons of water per day and There are 16 cups in a gallon.

To find : Which expression shows how to find the number of cups of water she drinks in a week.

Solution : We have given that

Katrina drinks of water per day = 0.5 galoons.

1 gallon = 16 cup .

So, Katrina drinks of water per day = 0.5 * 16 cups.

Katrina drinks of water per day = 8 cups.

1 week = 7 days .

Katrina drinks of water in 7 day = 8 *7 cups.

Katrina drinks of water in 7 day = 56 cups.

Therefore, Expression Katrina drinks of water in 7 day = 8 *7 cups .

option D.) 0.5 gallons / 1 day × 16 cups / 1 gallon × 7 days / 1 week

Step-by-step explanation:

The answer is found by doing analyzing the dimensions (units) of the quantities, placing each factor in a way that leads to the cancellation of the dimensions (units) until you reach the desired units.You want to find an amount whose final (desired) units are number of cups of water per week.Therefore, you have to change the given volume of water, that is in gallons, to cups, and the given unit of time, that is in days, to weeks.To do that, you use the conversion factors derived from the equivalences of the units:16 cups = 1 gallon division property ⇒ 1 = 16 cups / gallon

1 week = 7 days

division property ⇒ 1 = 7 days / weekThe final step is multiply the given amount, 0.5 gallons of water per day, by the conversion factors that wre just built: 0.5 gallon / 1 day = 0.5 gallon / (1 day) × 16 (cups / gallon) × (7 days / week)

this math ruins my brain

Step-by-step explanation:

what is asked: katrina drinks 0.5 gallons of water per day

what are the given: 0.5 gallons of water,week=7

what is the solution:

(16)(0.5)=8

8-7=1

what is the katrina drinks 1 cup per week
