a city has two water towers. one tower holds 8.4 x 103 gallons of water and the other tower holds 9.5 x 104 gallons of water. what is the combined water capacity of the two towers in scientific notation?

Answers

Answer 1
Answer:

Total capacity the tower holds 1.034 x 10^5  gallons of water

One tower holds 8.4 x 10^3 gallons of water

Other tower holds 9.5 x 10^4 gallons of water

The combined water capacity of the two towers in scientific notation is,

Total capacity the tower holds = 9.5 x 10^4 + 8.4 x 10^3

    = 9.5 x 10^4 + 0.84 x 10^4

    = 10.34 x 10^4

    = 1.034 x 10^5

An employee worked 160.5 hours in may, 165.75 hours in June and 152.25 hours in july. What was the average number of hours you worked each month?

Answers

To find the average, you have to add everything up and divide by the amount that you have. In this case, you need to add together 160.5, 165.75 and 152.25, and then divide by 3.
160.5+165.75+152.25= 478.5
You've then got to divide this by three.
478.5/3= 159.5
Therefore, the average hour worked each month bu the employee is 159.5

x - (x *23)/100

How do i figure this out?

Answers

Answer:

Slope of function A is greater than slope of function B

Step-by-step explanation:

You calculate the gradient (slope) of function B. That is, change in y divided by change in x.

Take point (0, 1) and (2, 5) from the graph of function B.

change in y = 4

change in x = 2

gradient = 2

b(x) = 2x + 1

Therefore the function B has a lesser slope than function A

8=8p+13-3p
How do you solve this equation?

Answers

p = -1
8=8p+13-3p
Subtract 8p and 3p
Thats 5p
Now
8=5p + 13
Subtract 13 from 8
-5 = 5p
Divide -5 by 5
-1 = p
remember you can do anything to an equaiton as long as you do it to both sides

8=8p+13-3p
group like terms
8=8p-3p+13
add like terms
8=5p+13
minus 13 from both sides
8-13=5p+13-13
-5=5p+0
-5=5p
divide both sides by 5
-5/5=5p/5
-1=1p
-1=p
p=-1
