Kent worked in the houseware section of a department store. This year he set a record high for vacuum sales with567 vacuum sold.
Gemiola [76]
First subtract the original high from the new high:
567 - 540 = 27 more vacuums sold.

Now divide the increase amount by the original high and multiply that by 100 to get the percentage:

27 / 540 = 0.05

0.05 * 100 = 5% Increase.

Two trains are traveling towards each other at a constant speed. The trains are currently 714 miles from each other. The speeds
shutvik [7]
55mph.

you can solve it using the equation distance=speed x time

your total distance is 714, and you have 2 trains, one traveling some speed, x, and one traveling x+8, both traveling for 7 hours. 
your equation would look like this
714 = x(7) + (x+8)(7)
and you can then solve for x, which would be 47. this is the speed of the slower train, but 47+8=55 with give you the speed of the faster train.

Stella [2.4K]

Answer 16.

Step-by-step explanation:

First you replace the xs with 1/2

(√2•1/2+3)/(6•1/2-5)

Then you solve the multiplications

2•1/2=1

6•1/2=3

Now write them in

(√1+3)/(3-5)

Simplify

(√4)(-2)

Root of 4 equals to

2/-2

And the answer is -1

Answer 17:

Replace x with 8

1/2•8^2-(1/4•8+3)

Solve parenthesis, multiplication first

1/2•8^2-(2+3)

1/2•8^2-(5)

1/2•8^2-5

Solve the 8^2 and the 1/2

1/2•64-5

32-5

The answer is 17

Which of the following expressions has a value of 26.48?
gulaghasi [49]

Answer:

26.48=\dfrac{662}{25}

Step-by-step explanation:

The given expression is 26.48. We need to write the equivalent expression for it. There are two numbers after decimal. It means that we can divide 2648 by 100 i.e.

26.48=\dfrac{2648}{100}

We know that, 2648 = 662 × 4 and 100 = 25 × 4

\dfrac{2648}{100}=\dfrac{662\times 4}{25\times 4}\\\\=\dfrac{662}{25}

Hence, 26.48=\dfrac{662}{25} is the equivalent expression.
