There are two numbers. Their GCF is 5. Their LCM is 150. The first number is 25. What is the second number?

There are no choices

Answers

Answer:

6

Step-by-step explanation:

Answer:

if 150 is a multiple, then all of the factors of the second number must also be factors of 150 which are: 5 (twice), 2 and 3.

Since 150 is the LCM, all of those factors must be either in our number or 25. Since 25 has just 5 (twice) as a factor, both 2 and 3 must be factors.

The remaining question is how many 5s we have. Since the GCF with 25 is 5, our number must exactly one 5.

So the factors of our number are: 2, 3, and 5. There is one number with exactly these factors = 2*3*5 = 30.

What is 20% of 85?



n = 20 • 85; 1,700


n = 0.2 • 85; 17


n = 20 • 0.85; 17


n • 0.2 = 85; 425

Answers

Answer: n= 0.2 * 85; 17

Step-by-step explanation: I guess what you're asking is which one of these is accurate. In that case mulitply the percent by the whole to find the part so 85 times 20% is 0.2 as a decimal so 85 times 0.2 = 17. 20% of 85 is 17 :)

20/100 x 85
Reduce the fraction with 20
1/5 x 85
Reduce the numbers with the greatest common factor 5

HELP!!! PLEASE WRITE A DETAIlED EXPLANATION OF HOW YOU GOT YOUR ANSWER!!!

Answers

Answer:

80 cm

Step-by-step explanation:

first i cut the shape into two small rectangles and one big rectangle the width of the two rectangles would be two because if you look across from the 8cm is says 4cm so take 4 cm subtracted from 8cm to get 4cm divide that by 2 because there are two rectangles to get 2cm. So to find the are for the rectangles I did 2cm times 12cm to get 24 cm. I multiplied that by 2 because there are two rectangles and got 48cm and set that number off to the side. For the big rectangle in the middle I did 4 cm multiplied by 8 cm because 4 cm is already provided but in order to get 8 cm i have to subtract 4 cm from 12 cm to get 8 cm. So I did 4 cm multiplied by 8 cm to get 32 cm. Then i added the total area of the small rectangles and the big rectangle and got 80 cm

one cubic foot of chemical weighs 60 pounds. How many pounds of the chemical can a container withe these dimensions hold? Picture Below!

Answers

Answer:

3600 pounds

Step-by-step explanation:

One cubic foot of a chemical weighs 60 pounds.

1 ft³ of chemical = 60 pounds

We need to find how many pounds in the container whose dimension 6 ft, 4 ft and 2.5 ft

l = 6 ft

b = 4 ft

h = 2.5 ft

Volume of box = lbh

                        = 6 x 4 x 2.5

                        = 60 ft³

As we are given

1 ft³ of chemical = 60 pounds

60 ft³ of chemical = 60 x 60 = 3600 pounds

Answer:

3600 pounds

The $XYZ$ company has to pay $5,000 for rent each month. In addition, their monthly electricity bill is $1.45 per kilowatt-hour of electricity used. If the total cost for both rent and electricity in January was $16,520.25, how many kilowatt-hours of electricity did they use?

Answers

Answer:

7,945 kilowatt-hours

Step-by-step explanation:

Since the monthly rent is $5,000, first subtract 5,000 from the total cost so that you only have the cost for the electricity bill:

16,520.25 - 5,000 = 11,520.25

Then, since the electricity bill is $1.45 per kilowatt-hour used, divide the new total by 1.45:

11,520.25 ÷ 1.45 = 7,945

Hope this helped!

7,945 kilowatt-hours
