Answer:
21.6 degrees
Step-by-step explanation:
the sum of angles in a triangle is 180 degrees
71 + x + (4x-11) = 180
open the brackets
71 + x +4x - 1 = 180
71 + 1 + x + 4x =180
72 + 5x =180
5x = 180 -72
5x = 108
x = 108/5 = 21.6
Answer:
m is greater than or equal to -9 the inequality sign flips when u divide by negative number
It look like that.
Diameter = 2 so the radius = 1/2 * diameter = 1in
Volume of the cylinder = pi r^2 h
where h = height of the cylinder = 9 in
so volume = pi * 1^2 * 9 = 28.27 in^2 to nearest hundredth
Answer:
1 - c
2 - A
Step-by-step explanation:
Hey There!
So for the first one we are given the dimensions of a rectangular prism and they want us to find the volume
Remember to find the volume we use the equation
V = length x width x height
so we just plug in the values
v = 2.6 x 2.1 x 3.9 = 21.294
the closest is 20 so C is your answer
For the second one we are given a triangular prism
and they want us to find the volume

b = base (10.3)
l = length (4)
h = height (7)
7x4=28
28x10.3=288.4
then we divide by 2
288.4/2=144.2
so your selected answer is correct
1 lap to ten minutes or 1:10 due to the fact that it takes ten minutes to run one lap. hope this helps, have a nice day :)
