Answer:

1. 11

2. 7

3. 4

4. 10

.

5. 17.2

6. 2.2

7. 3.3

8. 7.9

Step-by-step explanation:

When calculating square root, you always need to find a number multiplied by itself twice that gives the number

Example: \sqrt{64}

What number multiplied by itself twice gives 64? Number 8! because 8 × 8 = 64

Now cube root is a little bit different. This time, you will need to find a number multiplied by itself three times that gives that number.

Example: \sqrt{125}

What number multiplied by itself three times gives 125? Number 5! because 5 × 5 × 5 = 125

Hope this helps!

Anna-Maria has added 4 quarts of an alcohol in water solution to 1 quart of water and her ending product is a 36% alcohol in wat
fomenos
The concentration of solution would be the amount of the molecule divided by the volume. In this case, the solution concentration is 36% and the volume is 4 quarts + 1 quarts= 5 quarts. You are asked the concentration before 1 quarts added. The alcohol content should be same for both solutions. The answer should be:

concentration = alcohol content/ volume
alcohol content =concentration * volume
alcohol content1 =alcohol content2
36% * 5 quarts = concentration2 * 4quarts
concentration2= 36% * 5 quarts / 4 quarts= 45%

At the moment a hot cake is put in a cooler, the difference between the cake's and the cooler's temperature is 50° Celsius. This
dybincka [34]

Answer:

D(t)=50(0.8)^t

Step-by-step explanation:

We are given that

Initially the difference between the cake's and the cooler's temperature ,a=50 degree Celsius

r=\frac{1}{5}/min

We have to find the function that gives the temperature difference in degrees Celsius D(t).

We know that

D(t)=a(1-r)^t

Substitute the values

D(t)=50(1-\frac{1}{5})^t=50(1-0.2)^t

D(t)=50(0.8)^t

This is required function that gives the temperature difference in degrees Celsius.
