Answer:

H. 95°

Step-by-step explanation:

m∠BGC is 10° smaller than m∠CGD, which means that m∠BGC is x° - 10°

m∠DGE is 25° more than m∠EGF, which means that m∠DGE is x° + 25°

The sum of all angles in a placement like this will always equal 360°

So we put all the measures of all angles on one side of thee equation and set it equal to 360*

x° + x° - 10° + 2x° + 25° + 2x° + 3x° + 30° = 360°

After combining like terms we get 9x° + 45° = 360°

After some algebra we get x = 35°

Now at the start we said that m∠DGE is x + 25°

Plug in 35° for x and we get 35° + 25°

The final answer is m∠DGE = 95°

Edit: Sorry if my answer looks a bit confusing. This is actually my first answer on Brainly so I'm quite new to this experience.

Note: Enter your answer and show all the steps that you use to solve this problem in the space provided. Annika borrowed a book
ZanzabumX [31]

Answer:

Annika was 14 days late with her book.

Step-by-step explanation:

The first four days would cost Annika 1.0 dollar (4x0.25), then we need to divide the rest of the ammount by 0.30 to calculate for how many days she paid the 0.30 dollar fine.

4.00 - 1.00 = 3.00

3.00/0.30 = 10

Therefore, Annika was 4 +10 = 14 days late with her book.

shusha [124]

Answer:

50

Step-by-step explanation:

Adding up 20, 30, 40, 50, 60, 70, 80, we get 350.  There are 7 numbers in this set, so divide this 350 by 7.  We obtain the mean, 350/7 = 50 (Answer B)

Recipe asks for 4 1/2 pounds of chicken
ohaa [14]
Since a whole recipe asks for 4 1/2 pounds of chicken, then for a 1/2 recipe, you divide 4 1/2 by 2.

It’s easier to turn 4 1/2 to 4.50

4.50/2 = 2.25 or 2 1/4

You need 2 1/4 pounds of chicken for 1/2 of a recipe.

A= P+ I\\10000= 5000+ I\\I=10000-5000=5000\\I=Prt\\5000=5000*r*12\\r=5000/5000*12\\r=5000/60000\\r=0.083
