Answer:
Approximately 13.41
Step-by-step explanation:
First do square root of each, which is finding what number multiplies by its self to get the number.
For example: The square root of 80 is approximately 8.94, and the square root of 20 is approximately 4.47.
So: 8.94 + 4.47 = 13.41 (Add normally, but remember to put the decimal in the right place).

22.6 x 6 = 135
3/4 pages in 2 minutes how many pages in 1 minute
Answer:
3/8
Step-by-step explanation:
you can't split 3 in half to get a whole number, so you need to make it a different fraction with the same meaning to make it possible to divide by 2.
6/8 is the same as 3/4
divide by two to get 3/8 Don't divide the bottom number, just the top.
3/8 pages in one minute.

Step-by-step explanation:
An oil tanker can be emptied by the main pump in 5 hours. An auxiliary pump can empty the tanker in 7 hours. If the main pump is started at 7 PM, when should the auxiliary pump be started so that the tanker is emptied by PM?
Suppose you have entered 103 -mile biathlon that consists of a run and a bicycle race. During your run, your average velocity is 5 miles per hour, and during your bicycle race, your average velocity is26 miles per hour. You finish the race in 8 hours. What is the distance of the run? What is the distance of the bicycle race?
Answer:
so the answer will be 1
Step-by-step explanation:
An oil tanker can be emptied by the main pump in 5 hours.
An auxilary pump can empty the tanker in 14 hours.
If the main pump is started at 7pm, when should the auxilary pump be started
so that the tanker is emptied by 11pm?
:
Let t = no. of hrs to run the Aux pump
:
The main pump will run 4 hr (7 - 11 pm)
:
Let the completed job = 1; (an empty Tanker)
:
The shared work equation
4%2F5 + t%2F14 = 1
Multiply equation by 70 to get rid of the equation, results:
14(4) + 5t = 70
56 + 5t = 70
5t = 70 - 56
5t = 14
t = 14%2F5
t = 2.8 hrs to run the aux pump
:
2.8 hr = 2 + .8(60) = 2 hrs 48 min
:
Subtract 2:48 from 11:00 = 8:12 PM start the aux pump
;
;
Check solution
4/5 + 2.8/14 =
.8 + .2 = 1

Step-by-step explanation:
A company makes a profit of $1.38 million. This is $2.54 million more than last year. What was the profit last year?
The answer also asks for us to fill in the blank; "The profit last year was $__ million, so I need help filling in the blank.
The "million" part is already taken care of by your teacher.
====================================================
Explanation:
x = profit last year (millions of dollars)
x+2.54 = profit this year, which is 2.54 million more than last year
x+2.54 = 1.38
x = 1.38-2.54
x = -1.16
The profit last year was -1.16 million dollars
This is the same as writing -1,160,000 dollars of profit.
A negative profit indicates that the company lost money. This is when the company is spending more than what they earn (i.e. they are in some kind of debt).

f(x)=3x-7 input is 3
Answer:
The answer is f(x)=2
Step-by-step explanation:
When the input is given it means that the x is substituted by that number.
so 3x3-7.
3x3-7
9-7=2.
The f of x is equivalent to 2.

What is the area of a circle if the circumference is 29
Answer:
67 square units
Step-by-step explanation:
Circumference/pi = diameter
29/3.14 = 9.24
Radius = 9.24/2 = 4.62
A = pi * r^2
A = 3.14 * 4.62^2 = 67 square units
