Answer:
60 km/hr.
Step-by-step explanation:
When Dad caught up the the time he had been driving was 4 hours and the time Mom had been driving was 1 + 4 = 5 hours.
They both drove the same distance, d km.
For Dad:
speed = d / time
75 = d / 4
d = 75 * 4 = 300 km.
Mom took 5 hours to travel this distance, so
Mom's speed was 300 / 5 = 60 km/hr.
Answer:
591.6 x 10^2
Step-by-step explanation:
There are 3 green gumballs out of 6 in total. So, the odds of Jeff pulling out a green gum ball is 3/6, or 1/2.
There are 2 blue balloons out of 5 in total. So, the odds of Jeff pulling out a blue balloon is 2/5.
Therefore, the combined odds of Jeff pulling out a green gum and a blue balloon is 1/2 multiplied by 2/5, which is 2/10, or 1/5, Making the answer C.
TL;DR: The answer’s C.
I do not know the decimal, but I know the ratio. 7/50. I am not positive about my answer as a decimal but I think it is 7.50.
Area of square painting is 400 square inches.
Let the side of square painting is = a inch
So the area of square painting is =

square inch.
So


Length of wood trim to need to go around the painting is equal to the perimeter of square painting .
So the perimeter of square painting is = 4 * (side)
= 4* 20 = 80 inch.
So the required length of wood trim is = 80 inch.
