Answer:
160 square feet
Step-by-step explanation:
For this problem you are required to find the unit rate.
420 square feet / 2 ⅝ or 2.625 pounds =
160 square feet = one pound of wild flower seeds

Answer:
9 and 10
Step-by-step explanation:
The side length is the square root of the area, √90.
9² = 81
(√90)² = 90
10² = 100
The square root of 90 is between 9 and 10.
Variance is given by s^2 = [summation (x - mean)^2] / n.
mean = (90 + 75 + 72 + 88 + 85) / 5 = 82
Variance = [(90 - 82)^2 + (75 - 82)^2 + (72 - 82)^2 + (88 - 82)^2 + (85 - 82)] / 5
= [8^2 + (-7)^2 + (-10)^2 + 6^2 + 3^2] / 5
= (64 + 49 + 100 + 36 + 9] / 5
= 258 / 5
=258.
A. 2.5 laps is 1 km
It takes Angel 5 minutes to run a km
Jayden ran 1.2 laps in 5 minutes, so if you subtract 1/5 of the time that it took him to run that, then you would see how long it took him to go 1 km.
.2 × 5 = 1
So it took him 4 minutes to go 1 km
B. Half of what Angel ran in 2 minutes would give you what she ran in 1 minute, so half of 1 lap (2/5 km) is 1/5 km. So, Angel can run 1/5 km in 1 minute.
For Jayden, find 1/5 of the 6/5 km that he ran. 1/5 × 6/5 = 6/25 = .24 km in 1 mintue.
C. Jayden is running faster. Jayden can go 3 times the length that Angel can go in less than 3 times the amount of time
