Answer:

3 15/18

Step-by-step explanation:

well, 4 5/18 can't take away 8/18 with the fraction itself. so, you take 5 from 8 and get -3. then, take one whole number away and subtract the 18 from 3 (this was the negative 3) and you have the answer. so to conclude it 5 cant take away 8 so its like carrying. you take one whole number that is 18/18 and you subtract the 18 from 3.

Farmer Brown grows corn on his 110 acre farm. The yield for his farm is 17,600 bushels of corn. Farmer Diaz grows wheat on his farm. He plants 250 acres of wheat and has a yield of 13,750 bushels. What is the difference in the density per acre of the wheat and the corn?

A.35
B.105
C.140
D.3850

Answers

Answer:

Difference of density per acre of wheat and corn = 105

Step-by-step explanation:

Given:

Yield in 110 acre farm = 17,600 Bushes of corn

Yield in 250 acre farm = 13,750 Bushes of wheat

Find:

Difference of density per acre of wheat and corn

Computation:

Yield per acres Bushes of corn = 17,600 / 110

Yield per acres Bushes of corn = 160

Yield per acres Bushes of wheat = 13,750 / 250

Yield per acres Bushes of wheat = 55

Difference of density per acre of wheat and corn = Yield per acres Bushes of corn - Yield per acres Bushes of wheat

Difference of density per acre of wheat and corn = 160 - 55

Difference of density per acre of wheat and corn = 105

Alberto ran at a speed of 3 m/hr. After he ran 6 miles, Omar ran in the same direction with a speed of 4.6 m/hr.
How many hours will it take Omar to catch up to Alberto.

Answers

Answer:

1.3 Hours (1 Hour and 18 Minutes)

Step-by-step explanation:

It took Alberto 2 hours because he ran 3 miles an hour and the total distance he ran was 6 miles.

Now, you have to divide 6 (Alberto's distance) by 4.6 (Omar's rate) and you get 1.3043.

60=70-h I can't seem to find my answer and it a bit hard

Answers

Answer:

10

Step-by-step explanation:

We need to solve the equation . The equation is z

→ 60 = 70 - h

Subtracting 70 both sides .

→ 60 - 70 = 70 - h - 70

→ -10 = -h

Dividing both sides by -1 .

→ -h/-1 = -10/-1

→ h = 10

• Hence the value of h is 10 .

Two mechanics worked on a car. The first mechanic worked for 10 hours, and the second mechanic worked for 15 hours. Together they charged a total of $2475 . What was the rate charged per hour by each mechanic if the sum of the two rates was $200 per hour?

Answers

Answer:

1st: 105/h

2nd: 95/h

Step-by-step explanation:

10A+15B=2475 (1)

A+B=200 |*10 => 10A+10B=2000 (2)

From (1) - (2), we have 5B=475, so B=95

then A+95=200 so A is 105
