Answer: 29 feet.
Step-by-step explanation: The formula for the circumference of a circle is C = π d. In order to calculate the diameter of the tree we will use the same formula and solve for d.
91 = 3.14 x d
In order to solve for d you need to divide both sides for 3.14:
D = 28.98, rounded to the nearest foot is 29 feet.
0.4 is 100% - because it's the output value of the task. <span>If 0.4 is 100%, so wyou can write it down as 0.4=100%. </span><span>We know, that x is 15% of the output value, so we can write it down as x=15%. so your anser is 15</span>
terms: -5x, 4, -x, -1
like terms: 4 and -1, -5x and -x
coefficients: -5 and -1
constants: 4 and 1
(depending on your teacher, the - could not be considered part of the coeficient, meaning the coefficents would be -5 and 1, as well as just x, not -x)
Answer:
C
Step-by-step explanation:
Complementary means that the angles have a sum of 90° so we can write:
m∠A + m∠B = 90° → 3x + 2 + 8x = 90
11x + 2 = 90
11x = 88
x = 8 which means that m∠B = 8x = 8 * 8 = 64°.
Supplementary means that the angles have a sum of 180° so m∠C = 180° - m∠B = 180° - 64° = 116°.
