Answers

Answer:

0.25 lawns

Step-by-step explanation:

The computation of the number of lawns each hour is shown below;

M represent the mowed

Ewan has a mango farm that is 75 feet X
50 feet, and he also purchases a 20 feet X
10 feet plot of land. Find the total area of
the farm.

Answers

Answer:

3950 feet squared

Step-by-step explanation:

So first you have to multiply 75 by 50, so that is 3750.

Next you have to multiply 20 by 10 and you get 200.

Finally you had both 3750 and 200 in order to get 3950 and that is why the total area of the farm is 3950 feet squared.

Write the equation of the line with a slope of -5/4 and a y-intercept of 2.

b) y=2x-5/4
c) y=-1/4x+2
d) y=-5/4x+2

Answers

Answer:

D, y=-5/4x+2

Step-by-step explanation:

the slope always comes before "x", and the y-intercept comes last when written in slope intercept. So y=-5/4x+2 is correct.

Answer:

8 Hours

Step-by-step explanation:

Since 4 painters painting one house takes 14 hours, then one person would take 56 hours to paint the whole house. Hence, 4 x 14 = 56. If 7 people painted the house, then 8 hours would be needed since 56 / 7 = 8.

4 people x 14 hours = House

56 hours = House

56 hours is required to paint a house.

7 people x H hours=  House

7 people x H hours = 56

(7 people x H hours)/ 7 = 56 / 7

You divide 7 on both sides to isolate H on one side.

H hours = 8

So H = 8 which is the amount of hours needed.

a. Let x be the number. Write and solve an equation to find x. Show your work.
b. Does the solution of your equation solve the original problem? Explain.

Answers

Answer:

a) x = 34

b) yes, it checks out

Step-by-step explanation:

2x - 5 = 3(4 + 1/2x)

multiply both sides by 2 to eliminate fraction

2[2x - 5 = 3(4 + 1/2x)] = 4x - 10 = 24 + 3x

x - 10 = 24

x = 34

check

2(34) - 5 = 3(4 + 34/2)

What is an Arithmetic operation?

Combining operands with a single arithmetic operator specifies an arithmetic operation. The built-in functions ADD, SUBTRACT, DIVIDE, and MULTIPLY can also be used to specify arithmetic operations. in general, we use PEMDAS for calculating various arithmetic operations.

Given 25% of the marbels ar red. and also given 45 marble are red.

Hence Total marble will be,

Total marbles = [tex]\frac{45* 100}{25}[/tex] = 180.

Therefore the total number of marbles in the jar is 180.

Step-by-step explanation:

From the equation, we are informed that Mr. Robison rides 136 miles per hour on his bike ride and that he wants to ride more than 360 miles at the same rate during his next bike ride.

The inequality that represents all possible values for b, the number of hours Mr. Robison must bike will be:

136b > 360

b > 360/136

b > 2.65
