Answer:
Speed of car is 78 mph which travels the distance in 6 seconds.
Step-by-step explanation:
Given:
Speed of the car R = 52 mph
Time t = 9 seconds
We need to find the speed of a car that travels the given distance in 6 seconds.
Now first we will find the distance traveled by the car in 9 seconds.
Distance can be calculated by multiplying speed and time.
Distance =
Hence Total distance travel by car is 468 miles.
Now we will find the speed of a car that travels the given distance in 6 seconds.
Speed can be calculate by dividing Distance by time.
Hence;
Speed =
Hence Speed of car is 78 mph which travels the distance in 6 seconds.
Slope: 7 given point: (1,8)
y = 7x + b step 1 - plug in the slope in the formula
8 = 7(1) + b step 2 - plug in the given point
8 = 7 + b step 3 - simplify the expression
b = 1 step 4 - solve for b
y = 7x + 1 step 5 - plug in b
formula: y = 7x + 1
5 times the quotient of 2 numbers is 5(r/t)
Answer is the third option
5(r/t)
Answer:
5/12
Step-by-step explanation:
1/4 of the cakes is 60 divided by 4 which is 15. That goes to Helen
20 go to Sue
so far, he has given away 35 cakes out of the 60
he is left with 25 cakes
that is 25/60 which can be simplified to 5/12
