Perpendicular lines form 90 degree angles.
Letter C.
Answer:
79/10
Step-by-step explanation:
When making an improper fraction, you have to do the number on the outside times the bottom number of the fraction. So 7 x 10 is 70. Then we add the top number of the fraction, 70+9 = 79. You keep the bottom number (10) the same and put 79 on top. Leaving you with 79/10
Answer: 1.5 inches
Step-by-step explanation:
If two quantities are directly proportional, it means that an increase in the value of one quantity would cause a corresponding increase in the other quantity. Also, a decrease in the value of one quantity would cause a corresponding decrease in the other quantity.
Given that the amount a spring will stretch,S varies directly with weight, F, if we introduce a constant of proportionality, k, the expression becomes
S = kF
When S = 2.22 and L = 37, then
2.22 = 37k
k = 2.22/37 = 0.06
Therefore, the equation that relates the length S that the spring stretches to the weight F is
S = 0.06F
Therefore, if F = 25 pounds, then
S = 0.06 × 25
S = 1.5 inches
Answer:
Given speed of trolley = 125 meters per minute
Now we know that
Distance= Speed x time
Thus for the first case since the time of travel is less than 450 seconds thus the distance traveled is less than
Distance < 2.083 x 450 =937.5 meters
hence depending on the given information we cannot come to any conclusion weather the distance travelled is less than 800 m or greater than 800 m.
For the second case
since the time of travel is greater than 400 seconds
Thus the distance traveled is
which is greater than 800 meters.
Answer:
105 degrees
Step-by-step explanation:
since both sides of a line will add up to 180 we must subtract 75 from 180 since we already have 75 on the triangle side we subtract and get 105
