If we rewrite this equation, it would look like this:
, which is the equation for a straight line with a slope of -4/3 and a y-intercept of 20. The y-intercept exists when x = 0. "x" represents the number of minutes he drives, "y" represents the number of laps he drives. Slope is rise/run, or y/x, which gives us that he drives 4 laps in 3 minutes (the slope of our line). The y-intercept, when x = 0, tells us that when he has driven 0 minutes, or hasn't driven at all yet, he still has 20 laps to go. When y = 0, the x-intercept is
, and
. Multiply both sides by 3 to get that -60 = -4x and that means that x is 15. This means that from start to finish, it takes him 15 minutes to drive the 20 laps.
The answer is : $36.36
Step-by-step explanation:
The given box is a rectangular box. To find the felt needed to cover the box, we need to find the surface area of the rectangular prism.
Surface area of a rectangular prism = 2(l*w + w*h + h*l), where "l" is the length, "w" is the width and "h" is the height of the rectangular prism.
Given: l = 11 inches; w = 8 inches; and h = 6 inches.
Now plug in these given values in the above formula, we get
Surface area of the rectangular prism = 2 (11* 8 + 8*6 + 6*11)
= 2(88 + 48 + 66)
= 2(202)
= 404
The surface area of the rectangular prism = 404 square inches.
The felt cost 9 cents square inches.
Convert 9 cents to dollar.
9 cents = $0.09
To find the cost of the felt needed to cover prism multiply 404 by 0.09
The total cost = 404*0.09 = $36.36
Hope this helped :)))
There are 86,400 seconds in one day so in d days, there will be 86,400d seconds

Answer:
A por tiene todo la respuesta en tus ojos mi querido amigo
Answer: a:b:c:d = 16:24:30:40
You can also divide the ratio by 2 because all terms have 2 in common. Which would be a:b:c:d = 8:12:15:20
