Answer:

Answer:

1.2 acres of grass

Step-by-step explanation:

It takes 6.7 lb of seed to plant one acre of grass. The ratio of interest is 6.7 lb seed:1 acre of grass. We can find the acres of grass that can be planted with 8.04 pounds of seed using a conversion fraction.

8.04 lb × (1 acre/6.7 lb) = 1.2 acre

We can plant 1.2 acres of grass with 8.04 pounds of seed.

Answer: This is a proportion problem. 6.7lbs to one acre as 8.04 lbs is to x acres.

x= # lbs of seed to cover 8.04 acres

6.7/1=8.04/x

cross multiply

(6.7*x) =(1*8.04)

6.7x=8.04

divide both sides by 6.7

x= 1.2 pounds needed to cover 8.04 acres

What is Unitary Method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given:

Bonnie Armstrong earns $13.47 an hour plus time-and-a-half for weekend work.

If she worked regular 40 hours plus 8 hours of overtime.

So, the total pay she get

=$13.47 (40) + $20.21(8)

=$538.80 + $161.68

=$700.48

Hence, the total pay for the week is $700.48.

Tell how to find 81-16 using mental math

To use mental math think instead of 81 to 80 and 16 to 10 and subtract that and add the other numbers and subtract that and you will have your answer presto!

1 matches to 6 - subtract any way is 5

81-16=80-15

subtract both by 1

if there's a smaller digit, 2 numbers always add up by x-1

8-1=7

1+x=7

x=6
