Answer:
C. 10x=16
Step-by-step explanation:
3(2x-1)+4x=13
Distribute the 3 by multiplying it by 2x and -1.
6x-3+4x=13
Add same properties. 6x and 4x 6x+4x=10x
10x-3=13
Add 3 to both side get rid of the negative 3 -3+3=0 13+3=16
10x=16
Answer:
28°
Step-by-step explanation:
1. We can see that ∠GFH has two smaller angles within it: ∠1 and ∠2. Given that m∠GFH is 53° (the whole thing), and m∠2 is 25° (a part of it), we just have to subtract 25 from 53 to get the measure of ∠1.
Therefore, m∠1 = 28°.
Answer:
perimeter of the fountain = 15π ft. or 47.1 ft. to the nearest 10th
Step-by-step explanation:
The semicircles have a circumference of 1/2πd = 1/2π(10) = 5π
Both semicircles together have a length of 5π + 5π = 10π
The radius of the 1/4 circle is 10, so the diameter is 20
The length of the 1/4 circle's arc is 1/4 times the circumference of its circle
So, the length of that arc is 1/4π(20) = 5π
Now the perimeter of the fountain is 10π + 5π = 15π
