The answer is B because when you solve for x that is what you get
Answer: 67.5 meters
Step by step explanation
I think you meant the scale drawing is 9 cm so all you have to do is multiple 9 times 7.5 because 1 cm is 7.5 so if you multiple 9 times 7.5 you get how much it is in real life which is 67.5
Answer:
Step-by-step explanation:
The interior angles of a heptagon add up to 5*180 = 900
So
x + 143 + 116 + 135 + 135 + 116 + 155 = 900 Add up the known angles
x + 800 = 900 Subtract 800 from both sides
x + 800 - 800 = 900 - 800 Combine
x = 100

were the five is how much times you multiply the number by it self
Answer:
0.667 feet
Step-by-step explanation:
To get the total distance travelled, we would integrate the velocity v(t) equation with respect to time t.
Given that the particle moves from t = 0 to t = 2 seconds
Integrating v(t) = t2 - 1
we get
= t^3/3 - t
substituting the boundaries from t = 0 to t = 2 seconds, we get
= 2^3/3 - 2 - (0^3/3 - 0)
= 8/3 - 2 - 0
= 0.667 feet
