Answer:
r = 15
Step-by-step explanation:
10(8r + 23) = 1430
Divide both sides by 10.
8r + 23 = 143
Subtract 23 from both sides.
8r = 120
Divide both sides by 8.
r = 15
Anything that is inside the perenthasis are just like a regular math problem, so your answer should be:
C. 5
Answer:
$12.96
Step-by-step explanation:
determine what the decimal form of 8% is
⇒ 8% = 0.08
multiply $12 by 0.08
⇒ $12 x 0.08
⇒ $0.96
add $0.96 to $12
⇒ $12 + $0.96
⇒ $12.96
new price
⇒ $12.96
Answer:
122.7792 sq. m
Step-by-step explanation:
diameter= 8.4 m
therefore, radius = r = 4.2 m.......( as radius is 1/2 of diameter)
height = h= 12 m
only the exterior is to painted so the total surface area of the cylinder is taken,
total surface area of cylinder = 2π r( h+r)
=2* 3.14* 4.2*(12+4.2)
=122.7792 sq. m
The answer is A, 1. In the statement x^2 >x, if we try 4, 5 and 8 for x, we get 16, 25 and 64 for x^2. The statement is true. But if we try x = 1, when we square it we still have 1. Therefore for x=1, x^2>x is false.
