1.40 is 140/100 = 7/5
7/5 divided by 4 is 7/5 multiplied by 1/4 so the solution will be 7/20
It's .00009, right? So 9.0 x 10 to the -5
Average speed of Ashley = 15 miles per hour
Time she has = 6 hours
Distance can be covered = speed × time = 15×6 = 90 miles
But the distance of her friend's house is 96 miles.
So she will not be able to make it.
Answer:
z = 4xy
Step-by-step explanation:
IF Z varies directly with the product of x and y, then;
Z = kxy
k is the proportionality constant
If x=2,y=0.5, z=4,
4 = k(2)(0.5)
4 = k * 2 * 1/2
4 = k
Swap
k = 4
Substitute into the original expression
z = kxy
z = 4xy
This gives the required expression
