Charra [1.4K]3 years ago

Answer:

M<GEF=30

M<DEF=40

Step-by-step explanation:

First you want to solve for x. to do that you put both of the equations together and make it equal to 70 since M<GED=70. so you would get 2x+10+5x-10=70.

when you solve that you get x=10. next you substitute x with 10 in the other equations to solve for the unknown measure angle. So M<GEF=2(10)+10 and M<DEF=5(10)-10. When you solve that you get M<GEF=30 and M<DEF=40. you can check this by adding them together and they add up to 70 which is the M<=GED.

A city has a population of 370,000 people. Suppose that each year the
kherson [118]

Answer:

463,185

Step-by-step explanation:

3.75% of 370,000 is 13875

370,000 + 13875 = 383,875

(end of first year)

3.75% of 383,875 is 14395.312, rounding it down to 14395

383,875 + 14,395 = 385,370

(end of second year)

3.75% of 385,370 is 14451.375, rounding it down to 14451

385,370 + 14,451 = 399,821

(end of third year)

3.75% of 399,821 is 14993.287499999999, but I'm rounding it down to 14,933

399,821 + 14,933 = 414,754

(end of fourth year)

3.75% of 414,754 is 15553.275, but I'm rounding it down to 15,553

414,754 + 15,553 = 430,307

(end of fifth year)

3.75% of 430,307 is 16136.512499999999, but I'm rounding it down to 16,136

430,307 + 16,136 = 446,443

(end of sixth year)

3.75% of 446,443 is 16741.6125, but I'm rounding it up to 16,742

446,443 + 16,742 = 463,185

(end of seventh year)

Hopefully, that helped :) I rounded to make the numbers easier to work with, rounding down with numbers below 5, and rounding up with numbers 5 and above.
