Step-by-step explanation:
Complementary means that 2 angles equal 90 degrees. If one angle is 40 degrees, 90-40 would give you the other angle. 90-40 is 50, so the other angle should measure 50 degrees.
50 degrees

Answer:
15.78%
Step-by-step explanation:
Let x represent the fraction of pay that Alec needs to save each week. Then at the end of 6 weeks, he will have ...
159.00 = 6(x(167.91))
x = 159.00/(6·167.91) ≈ 0.157823 ≈ 15.78%
Alec will need to save 15.78% of his pay.
_____
<em>Additional comment</em>
We recognize that $159 is almost a whole paycheck of $168, so Alec needs to save approximately 1/6 of his paycheck each week. We know that 1/6 = 16.67%, so the nearest reasonable answer choice is 15.78%.
Answer:
160
Step-by-step explanation:
This is basically saying "8 is 5% of what number (total)"?
<u>Note:</u> 5% in decimal is 5/100 = 0.05
When translating a word statement into algebra, we need to note that "is" means "equal" and "of" means "multiplication".
Let's translate <u>"8 is 5% of what number (total)"</u> (letting total number of coins be n):
8 = 0.05 * n
<em>solving, gives us:</em>
<em>8 = 0.05*n</em>
<em>n = 8/0.05 = 160</em>
<em />
<em>Hence, total number of coins Mia has is 160</em>
