we know that
--------> equation 
and

substitute the equation
in the inequality

Step 
<u>Convert
to F</u>
substitute in the formula

Step 
<u>Convert
to F</u>
substitute in the formula

therefore

the answer is the option
B. −30 < 5 over 9 (F − 32) < 130; −22 < F < 266
(100% - 7%) × 7,500
= 93% × 7,500
= 93 ÷ 100 × 7,500
= 93 × 7,500 ÷ 100
= 697,500 ÷ 100
= 6975
hope this helped
240%
Step-by-step explanation:
if there is 240 grams then you just put a percent sing but are you asking What is the percentage of sugar in each cup? by spoons?
Answer:
-1.
Step-by-step explanation:
1) according to the DeMoivre's theorem:

2) if cos(π)=-1 and sin(π)=0, then cosπ+i*sin(π)=-1.
There is two ways to attempt this problem. The first is that you could prove that angle CDE is congruent to angle DAB (of which I'm not totally sure is possible) or option two. Your second choice is to prove that Line segment DE is a flat line because line segment AB is also a flat line.
