1). Aziz has a job mowing lawns in the summer. The graph below shows the amount of earnings, in dollars, based on the number of lawns Aziz mows. Enter an equation to represent the amount of earnings, e, in dollars, that Aziz makes in terms of the number of lawns, n, that he mows.
Answer:
The equation that represents the amount that Aziz earns for the number of lawn he mows is e = 15.875 × n
Step-by-step explanation:
From the graph, we have;
For the point where n = 4, we have e ≈ 63.5
Therefore, we have;
The slope = Δn/Δe = 63.5/(4) = 15.875
The coordinates of the points plotted on the graph are as follows;
n = 0, e = 0, therefore, the y-intercept is 0, and y = slope × x
n = 1, e = 1 × 0.79375 = 15.875
n = 2, e = 2 × 15.875 = 31.75
n = 3, e = 2 × 15.875 = 47.625
n = 4, e = 4 × 15.875 = 63.5
We have, e = 15.875 × n
Where, n represents the number of lawns Aziz mows, and n represents the amount of earnings Aziz makes in dollars
Therefore, the equation that represents the amount that Aziz earns for the number of lawn he mows is e = 15.875 × n

A piece of cardboard has the dimensions (x + 15) inches by (x) inches with the area of 60 in 2 . Write the quadratic equation that represents this and show your work. Then find the possible value(s) for x, and find the actual dimensions of the postcard.
Answer:
[tex]x^2 + 15x - 60 = 0[/tex]
The actual dimension is 18.28 by 3.28
Step-by-step explanation:
Given
Dimension:
[tex](x + 15)\ by\ x[/tex]
[tex]Area = 60in^2[/tex]
Required
Determine the quadratic equation and get the possible values of x
Solving (a): Quadratic Equation.
The cardboard is rectangular in shape.
Hence, Area is calculated as thus:
[tex]Area = Length * Width[/tex]
[tex]60= (x + 15) * x[/tex]
Open Bracket
[tex]60= x^2 + 15x[/tex]
Subtract 60 from both sides
[tex]x^2 + 15x - 60 = 0[/tex]
Hence, the above represents the quadratic equation
Solving (b): The actual dimension
First, we need to solve for x
This can be solved using quadratic formula:
[tex]x = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}[/tex]
Where
[tex]a = 1[/tex]
[tex]b = 15[/tex]
[tex]c = -60[/tex]
So:
[tex]x = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}[/tex]
[tex]x = \frac{-15 \± \sqrt{15^2 - 4*1*-60}}{2*1}[/tex]
[tex]x = \frac{-15 \± \sqrt{225 + 240}}{2}[/tex]
[tex]x = \frac{-15 \± \sqrt{465}}{2}[/tex]
[tex]x = \frac{-15 \± \21.56}{2}[/tex]
Split:
[tex]x = \frac{-15 + 21.56}{2}[/tex] or [tex]x = \frac{-15 - 21.56}{2}[/tex]
[tex]x = \frac{6.56}{2}[/tex] or [tex]x = \frac{-36.36}{2}[/tex]
[tex]x = 3.28[/tex] or [tex]x = -18.18[/tex]
But length can't be negative;
So:
[tex]x = 3.28[/tex]
The actual dimensions: [tex](x + 15)\ by\ x[/tex] is
[tex]Length =3.28 +15[/tex]
[tex]Length =18.28[/tex]
[tex]Width = x[/tex]
[tex]Width =3.28[/tex]
The actual dimension is 18.28 by 3.28

Eduardo mixed 5 pounds o cashews and almonds. Cashews cost $8 per pound and almonds cost $6 per pound. The total cost of the mixture was $33. How much of the mixture was almonds?
Answer:
3.5 pounds of the mixture was almonds
Step-by-step explanation:
Assume that the mixture contains x pounds of cashews and y pounds of almonds
∵ x represents the amount of cashew
∵ y represents the amount of almond
∵ Eduardo mixed 5 pounds of cashews and almonds
∴ x + y = 5 ⇒ (1)
∵ Cashews cost $8 per pound
∵ Almonds cost $6 per pound
∵ The total cost of the mixture was $33
→ Multiply x by 8 and y by 6 and equate their sum by 33
∴ 8x + 6y = 33 ⇒ (2)
Now we have a system of equations to solve it
→ Multiply equation (1) by -8 to eliminate x
∵ -8(x) + -8(y) = -8(5)
∴ -8x - 8y = -40 ⇒ (3)
→ Add equations(2) and (3)
∵ (8x + -8x) + (6y + -8y) = (33 + -40)
∴ -2y = -7
→ Divide both sides by -2
∴ y = 3.5
∵ y represents the amount of almond
∴ 3.5 pounds of the mixture was almonds
Evaluate:
(4/25)^1/2 in fraction
Answer:
As
[tex]\left(\frac{4}{25}\right)^{\frac{1}{2}}=\frac{2}{5}[/tex]
Therefore, option C is true.
Step-by-step explanation:
Given the expression
[tex]\left(\frac{4}{25}\right)^{\frac{1}{2}}[/tex]
as
[tex]\mathrm{Apply\:exponent\:rule}:\quad \left(\frac{a}{b}\right)^c=\frac{a^c}{b^c}[/tex]
so the expression becomes
[tex]\left(\frac{4}{25}\right)^{\frac{1}{2}}=\frac{4^{\frac{1}{2}}}{25^{\frac{1}{2}}}[/tex]
[tex]=\frac{4^{\frac{1}{2}}}{25^{\frac{1}{2}}}[/tex]
[tex]=\frac{2}{25^{\frac{1}{2}}}[/tex]
[tex]=\frac{2}{5}[/tex]
Hence,
[tex]\left(\frac{4}{25}\right)^{\frac{1}{2}}=\frac{2}{5}[/tex]
Therefore, option C is true.

A pair of boots are $94.99. They are 25% off. With this
discount, what is the sale price? Round to nearest
cent if necessary.
If there are 25% discount on the pair of shoes, then the sale price of boots are, $71.24
What is the sale price ?Sale price refers to the price at which a product or service is offered for sale after a discount or reduction from its original or regular price. Sale price is a promotional tool used by retailers to encourage customers to purchase products or services by offering them at a lower price than their regular price. The purpose of a sale price is to increase sales and generate revenue, as well as to clear inventory, attract new customers, and increase brand awareness. The calculation of sale price is typically performed by subtracting a certain percentage or dollar amount from the original or regular price.
Given that,
The boots are $94.99 and are 25% off,
so the discount amount is
⇒ $94.99 x 0.25 = $23.75.
The sale price of the boots is
⇒ $94.99 - $23.75
⇒ $71.24
Rounded to the nearest cent, the sale price is $71.24

A bathtub contains 12 gallons of water. With these 12 gallons, the bathtub is only 30% full. How many gallons of water can the bathtub hold when it is completely full?
Answer:
40 gallons
Step-by-step explanation:
Let the number of gallons that would completely fill the bathtub be represented by N.
Since 12 gallons of water gives 30% of the number of gallons to fill the bathtub, then;
30% of N = 12
[tex]\frac{30}{100}[/tex] x N = 12
30N = 12 x 100
30N = 1200
divide both sides by 30,
N = [tex]\frac{1200}{30}[/tex]
= 40
The number of gallons that would completely fill the bathtub is 40 gallons.

The scale factor of two similar polygons is 2:3. The perimeter of the larger polygon is 150 centimeters. What is the perimeter of the smaller polygon?
The perimeter of the smaller polygon from the given ratio is 100 centimeters.
What is scale factor?A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).
The basic formula to find the scale factor of a figure is expressed as,
Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape.
Given that, the scale factor of two similar polygons is 2:3.
The perimeter of the larger polygon is 150 centimeters.
Let x be the perimeter of the smaller polygon.
Now, 2/3 =x/150
⇒ x=100 centimeters
Therefore, the perimeter of the smaller polygon is 100 centimeters.

Answer:
7/15
Step-by-step explanation:
find a common demonator for example 15
you would do 4x3 for 12 and 5x3 for 15 so your first fraction would be 12/15
for the second fraction you will do 1x5 and 3x5 so your fraction would be 5/15
then you just subtract.
Answer:
7/15
Step-by-step explanation:
4/5 - 1/3. Change the denominators to 15, do they same to the numerators which is multiply by 5. You then have 12 minus 5 = 7. So 7/15.

A lifeguard is in an observation chair and spots a person who needs help. The angle of depression to the person is 22°. The eye level of the lifeguard is 10 feet above the ground. What is the horizontal distance between the lifeguard and the person? Round to the nearest foot.
Answer:
The horizontal distance between the lifeguard and the person is approximately 24.751 feet.
Step-by-step explanation:
At first we include a geometrical representation of the statement, which is shown in the image attached below. We can determine the horizontal distance between the lifeguard and the person by means of the following trigonometrical relationship:
[tex]\tan \theta = \frac{OL}{OP}[/tex] (1)
Where:
[tex]\theta[/tex] - Angle of depression to the person, measured in sexagesimal degrees.
[tex]OL[/tex] - Height of the lifeguard above the ground, measured in feet.
[tex]OP[/tex] - Horizontal distance between the lifeguard and the person, measured in feet.
If we know that [tex]OL = 10\,ft[/tex] and [tex]\theta = 22^{\circ}[/tex], then the horizontal distance between the lifeguard and the person is:
[tex]OP = \frac{OL}{\tan \theta}[/tex]
[tex]OP = \frac{10\,ft}{\tan 22^{\circ}}[/tex]
[tex]OP \approx 24.751\,ft[/tex]
The horizontal distance between the lifeguard and the person is approximately 24.751 feet.
