Answer:
7,200
Step-by-step explanation:
If you start with a ratio in the form p/q and want a ratio with a denominator of 1, simply divided p by q.
So suppose you are given the ratio 35/10 (so that p = 35, q = 10).
Then divide 35 by 10 which gives 3.5.
<span>So the units ratio is 3.5:1 or (7/2):1</span>
Answer:
The prime factorization of 450 = 2•3 2 •5 2 . The prime factors of 450 are 2, 3 and 5.
Step-by-step explanation:
"Supplementary" angles add up to 180°.
Opposite angles are supplementary, so . . .
(12x - 4) + (19x - 2) = 180°
Clear the parentheses: 12x - 4 + 19x - 2 = 180°
Add up all the x's on the left side: 31x - 4 - 2 = 180°
Add up the plain old numbers on the left side: 31x - 6 = 180°
Add 6 to each side: 31x = 186°
Divide each side by 31 : <em>x = 6°</em>
Well ! Now that you know that x = 6° . . .
Angle EPC is (12x - 4)°
That's (12·6 - 4)°
Which is (72 - 4)°
Which is <em>68°</em>
