The millers drove 150 miles in 3 hours. At a rate, how long does it take to drive 400 miles?

8 hours

Step-by-step explanation:

We can use ratios to solve

150miles         400 miles

=

3 hours           x hours

Using cross products

150x = 400*3

150x = 1200

150x/150 = 1200/150

x =8

8 hours

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
