Answer: The speed of the car is 45.3 miles per hour.
Step-by-Step Explanation: Let 'x' be the speed of the car.
60 × 2/3 = 120/3 = 40
30 × 1/5 = 151/5
151/5 /40 = x / 60
151 / 200 = x / 60
=> x = (151×60) / 200
=> x = 45.3
Answer:
The car was traveling at an average speed of 45.3 miles per hour.
Step-by-step explanation:
We need to figure out how many minutes are in 2/3 of a hour. If we divide 60 minutes by 3 we get 20 minutes, so 2/3 of 60 minutes is (20 minutes x 2) 40 minutes.
We now know that the car traveled 30.2 miles in 40 minutes. We want to know if it traveled for 60 minutes, what would the average speed be. The ratio will be the same, so we want to solve for x (miles):
30.2/40=x/60
We then cross multiply:
30.2x60=40(x)
1,812=40(x)
Divide each side by 40
1,812/40 = x
x=45.3

Answers
Answer:
I can tell you the first one and you can figure it out from there. 70 is 40% persent of what number? Well, we can chop 40% to 20% and chop 70 in half and we get 35. So 35 = 20% So we multiply 35 by five, and get 175. So 70 is 40% of 175.
Step-by-step explanation:
16 is 25% of 54
12 is 96% of 12.50
18 is 60% of 30
5% of what number is 25 is 20
20% of what number is 96 is 19.2

Answers
Answer:
The y-intercept is positive 15
Step-by-step explanation:
Answer: y=3/2x-3, Option C
Step-by-step explanation: First off, plug this information in to the point slope form equation: y-y1=m(x-x1) then solve for y. The m would be the slope, 3/2. The point (4,3) the x1 = 4, the y1 = 3. So plugged in the equation would be: y - 3 = 3/2 (x - 4). Then distribute and add 3 to both sides to solve for y.
