Answer:
B. 121
Step-by-step explanation:
Complete the square.
Take half of the middle term, 22, and square it.
So 11^2 = 121.
First take 400 and divide it by 2.5 to find the hourly rate. Then divide 600 by the hourly rate (160) to get 3.75 hours. My work is listed below.
Answer:
m= 4.5 miles
Step-by-step explanation:
Let the number of miles Evelyn can run be m and can be modeled by the equation below
m= kx
Where x Is the Minutes
When m= 3
x= 40
3= k40
k= 3/40
If x= 60
m=3/40(60)
m = (60*3)/40
m= 180/40
m= 4.5 miles
The answer is 88 Bc 8 x 11 is 88
3/7 = 0.43 (approx.)
4/9 = 0.44 (approx.)
Hence, 4/9 is bigger.
