Nate starts a lawn-mowing business. In his business, he has expenses and revenue. Nate's expenses are the cost of the lawn mower
Korolek [52]

The question is incomplete. The complete question is :

Nate starts a lawn-mowing business. In his business, he has expenses and revenue. Nate's expenses are the cost of the lawn mower and gas, and his revenue is $25 per lawn. At what point will Nate's revenue exceed his expense?

Cost of lawn mower = $ 200

Cost of gasoline = $ 2 per lawn

Solution :

Given :

Cost of the lawn mower = $ 200

The cost of gasoline expense for one lawn = $ 2

The revenue generated for one lawn = $ 25

So let the number of lawn to be mowed = x

Therefore the total expenses = $200+2x$

So, the total revenue = $25x$

The point for which the revenue will exceed the total expenditure will be :

$25x \geq 200+2x$

So at x=9,  \ 225 > 218

Thus the revenue exceeds the total expenditure after mowing 9 number of lawns.

The polygons are similar, but not necessarily drawn to scale. Find the value of x.
alexandr402 [8]

If the shapes are similar, the correspondent sides are in proportion:

AB\div DE = BC \div EF

Let's plug the values and solve for x:

5x \div 5 = 4 \div x \iff \dfrac{5x}{5}=\dfrac{4}{x}\iff x = \dfrac{4}{x}

Multiply both sides by x to get

x^2=4 \iff x=\pm2

The only feasible solution, though, is x=2, because it wouldn't make sense to have negative lengths.

The percentage increase in the area of a rectangle if each of its sides is increased by 20% is.
SVETLANKA909090 [29]

The percentage increase in the area of a rectangle is 44% if each of its sides is increased by 20%.

<h3>What is a rectangle?</h3>

It is defined as two-dimensional geometry in which the angle between the adjacent sides is 90 degrees. It is a type of quadrilateral.

It is defined as the area occupied by the rectangle in two-dimensional planner geometry.

The area of a rectangle can be calculated using the following formula:

Rectangle area = length x width

New length = (120x/100)  m

New breadth = (120y/100)  m

New area = (6x/5 × 6y/5) m²

The difference between the original area = xy

new area 36xy/25

Percentage increase = (11xy/25 1/xy x 100)

= 44%

Thus, the percentage increase in the area of a rectangle is 44% if each of its sides is increased by 20%.
