Answer: 60 in
Step-by-step explanation:
Hi, to answer this question, first we have to calculate the diameter of one flotation device:
Circumference of a circle C = (3.14) (diameter)
Replacing with the values given:
62.8 =3.14 d
Solving for d (diameter)
62.8 /3.14 =d
20in = d
Now, since the three flotation devices are identical, we simply have to multiply the diameter of one device by 3 , to obtain length of the flotation devices lined up.
20x3 =60 in

If you mean the measure of angle A then the answer is 28°
Answer:
125
Step-by-step explanation:
that would be , by proportion. 5 * 800 / 32
= 125 students
(A) because a right angle is 90 degrees and has a equal eqivalent to get to 100
Answer:
-31.2x + 28.7y + 10.5
Step-by-step explanation:
Step 1: Write expression
2.5(4.2 + 7.4y) - 3.6(8x - 4.5y) - (2.4x + 6y)
Step 2: Distribute
10.5 + 18.5y - 28.8x + 16.2y - 2.4x - 6y
Step 3: Combine like terms
-31.2x + 28.7y + 10.5
