Answer:
43.82 mph
266.67 feet
Step-by-step explanation:
Given :
S = √30fl
S = speed of car
f = drag Coefficient
l = Length of skid mark
If f = 0.8 ; l = 80 feets
s = √30fl
s = √(30*0.8*80)
s = √1920
s = 43.817
s = 43.82 mph
B.)
s = 80 mph
f = 0.8
s = √30fl
80 = √30*0.8*l
80 = √24l
Square both sides
80² = 24l
6400 = 24l
l = 6400/24
l = 266.67 feets
1. Would be 58/11
Because we convert the mixed number to an improper fraction, 5x11+3/11. We then would multiple the numbers with gives us 55+3/11. We add that giving us 58/11
Hi!
1. Your answer should be the first option. (It looks the best to me)
2. it is the last option because it's the only one that's identical to the original picture.
3. It should be the third option since there are 10cm on the top of the shape.
4. a total of 39
Hope that helps, good luck! :)
Answer: F (False)
Step-by-step explanation:
Jointly variation has the following form:
y=kxz
Where k is a constant of propotionality.
Substitute values:
If y=16, x=4 and z=2, then k is:
If x=-8 and z=-3 the the value of y is:
Then the answer is FALSE.
Answer:
p/q = x
