We know that
A bowling lane<span> is 42 inches wide and </span>60 feet<span> long
1 ft-------> 12 in
60 ft-----> X
X=60*12------> X=720 in
</span>
[the length of a circumference]=2*pi*r
for r=8.5/2------> r=4.25 in
[the length of a circumference]=2*pi*4.25---------->26.69 in
if 26.69 in represent---------------> 1 revolution
720 in (bowling lane)------------> X
X=720/26.69------> X=26.98 revolution
the answer is
26 revolutions
Answer:
complementary
Step-by-step explanation:
because angle 20 and 70degree their name is complementary
Answer:
C. x = 7
Step-by-step explanation:
All angles of a square add up to 360° and there are 4 angles in every square. Since all angles of a square are 360/4 = 90, Then 12x + 6 = 90.
12x + 6 - 6 = 90 - 6
12x = 84
12x/12 = 84/12
x = 7
