Side BC is 4 meters long. Side CD is twice the length of the side BC. What is the length of side LM. Explain your reasoning.

Mathematics
1 answer:
Misha Larkins [42]2 years ago
4 0

Answer:

LM = 18

Step-by-step explanation:

BC = 4

CD is twice that, so CD is 8

Now, remembering that the area of ABCD = 32 and JKLM = 72, divide 72 by 32.

You get 2.25. This is how much bigger JKLM is than ABCD.

Using that, multiply the length of CD (which is 8) by 2.25 to get the length of LM.

You'll get 18.

Hope this helps!

You make $7 an hour. You work 40 hours a week for a year. (52 weeks) How much will you make?
valina [46]

If you made $7 an hour and worked for 40 hours, every day for a year, you would make $14,560 a year and about $1,213.33 a month.

Because 7 x 40 = 280 (which is how much money you make a week.)

And 280 x 52 = 14,560 (because you would work for 52 weeks).

I hope this helped! Good luck and have a great night!

sherrie opened 5 bags of peanuts and counted a total of 75. At this rate, how many peanuts would be in 8 bags.
Alenkasestr [34]

Answer:

There should be 120 peanuts

Step-by-step explanation:

We can use ratio's to solve this problem

5 bags

75 peanuts


5 bags           8 bags

---------------  = ------------------

75 peanuts      x peanuts

Using cross products

5x = 75*8

5x = 600

Divide each side by 5

5x/5 = 600/5

x = 120
