Mary earns $12 per hour, plus 10% commission on all her sales. Mary worked 10 hours and her sales were $1,500. How much money
did Mary earn?
First, you multiply 12 and 10 to get how much money she earned in 10 hours. She earned 120 dollars in 10 hours. Next, you multiply 10% and 1500. You turn 10% into 0.10, and multiply by 1500 to get 150. Finally you would add 150 and 120 to get $270. Mary earned $270.
Once the child in the sample problem reaches the bottom of the hill, she continues sliding along the flat, snow-covered ground until she comes to a stop. If her acceleration during this time is -.392m/s^2 how long does it take her to travel from the bottom of the hill to her stopping point
Sample problem is;
A child slides down a steep, snow covered hill with an acceleration of 2.82 m/s². Her initial speed is 0.0 m/s² and her final speed is 15.5 m/s travelling from top to bottom of the hill.
Answer:
t = 39.54 s
Step-by-step explanation:
We are told that her acceleration is now -0.392 m/s²
Thus; a = -0.392 m/s²
From the sample problem, we have;. Initial velocity = 0 m/s
Final velocity = 15.5 m/s
However, in this question, we want to find the time from the bottom of the hill to her stopping point.
This means her initial velocity will now be; u = 15.5 m/s and final velocity since she will come to rest will be v = 0 m/s
To find the time it takes her to travel from the bottom of the hill to her stopping point, we will use Newton's equation of motion and so, we have;
v = u + at
making t the subject, we have;
t = (v - u)/a
t = (0 - 15.5)/(-0.392)
t = 39.54 s

Which of the following equations could represent the points in the table? Select all that apply.
Answer:
Options (A) and (C)
Step-by-step explanation:
From table attached,
Let the equation of a linear equation that represents the input-output values in the table is,
y - y' = m(x - x')
Where (x', y') is a point lying on the graph.
And m = slope of the line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Slope of the line passing through (0, 11) and (1, 5) will be,
m = [tex]\frac{11-5}{0-1}[/tex]
m = -6
Therefore, equation of the line passing through (0, 11) and slope = -6 will be,
y - 11 = -6(x - 0)
Equation of a line passing through (1, 5) and slope = -6 will be,
y - 5 = -6(x - 1)
Equation of a line passing through (2, -1) and slope = -6 will be,
y + 1 = -6(x - 2)
Equation of a line passing through (3, -7) and slope = -6 will be,
y + 7 = -6(x - 3)
Therefore, Options (A) and (C) are the correct options.
write an equation of a line passing through point p(4, 0) that is parallel to the line -x+2y=12
Answer:
y = [tex]\frac{1}{2}[/tex]x - 2
Step-by-step explanation:
Given parameters:
Coordinates = p(4,0)
Equation of the line -x+2y=12
Solution:
A line parallel to the given line will have the same slope as it is;
-x+2y=12
2y = x + 12
y = [tex]\frac{1}{2}[/tex]x + [tex]\frac{12}{2}[/tex]
Since this conforms to y = mx + c where;
x and y are the coordinates
m is the slope
c is the intercept
Our slope is [tex]\frac{1}{2}[/tex]
The equation of the line is
y = mx + c
let us find c;
c = y - mx
c = 0 - ([tex]\frac{1}{2}[/tex] x 4)
c = -2
Now the equation of the line parallel to the line given is;
y = [tex]\frac{1}{2}[/tex]x - 2
I need the answer!!!! The original price of Doritos is the same at both Wal-Mart and Kroger. Jon found out that Wal-Mart had Doritos on sale at $0.50 off per bag and bought four bags. Later that day, he found out that Kroger had Doritos on sale at $1 off per bag and bought six bags. If he paid the same amount at both stores, what was the original price of Doritos?
write an equation and solve by using the distributive property, combining like terms, and eliminating the variable on one side of the equation. You must SHOW YOUR WORK!!!!
Answer:
I believe it would be $2 per bag normally.
Step-by-step explination:
If you take $2 and subtract $.50 it is $1.50. Take that multiplied by the number of bags he bought (4), would mean he spent $6 at Wal-mart.
Now $2 subtracted my the sale of $1, is $1 per bag. If he bought 6 bags at Kroger, 1 multiplied by 6, would equal 6. Meaning he spent $6 at both stores if the price was $2.

Write an equation of the line passing through point P(4,3) that is parallel to the line y = 12(x+4).
Answer:
y=12x-45
Step-by-step explanation:
First we want to get y=12(x+4) into Slope intercept form which is y=mx+b and we do that by multiplying 12 by x so we get 12x and multiplying 12 by 4 so we get 48.
Now we have:
y=12x+48
where the slope is 12.
Parallel lines have the same slope. so the line that goes through (4,3) will have the same slope.
Now that we have a slope and a point we want to write an equation in point-slope form: y-y1=m(x-x1)
Step 1 for this: y-3=12(x-4)
Step 2: we will distribute and solve for y so our answer is in slope intercept form.
Step 3: we now have the equation y-3=12x-48 after distributing now we add 3 to -3 so it cancels out and we add 3 to -48 and we get -45
Our answer is y=12x-45

John has two coupons to use at a clothing store. One is for $20 off and
the other is for 20% off. John wants to purchase a shirt with one of the
coupons and wants to pay the least amount that he can. Choose the
answer that BEST describes the situation.
A. The shirt will have the lowest price with the $20 off coupon
B. The shirt will have the lowest price with the 20% off coupon.
C. The shirt will cost the same with either coupon.
D. It depends on the cost of the shirt as to which coupon will help John pay the lowest
price
Answer: D. It depends on the cost of the shirt as to which coupon will help John pay the lowest price.
Step-by-step explanation:
You do not know how much a 20% discount is unless you know the price of the shirt. This can be more or less than $20, so you don’t know.
Hope this helps!
Answer:
D.
Step-by-step explanation:
For example if a shirt was $100 dollars, 100-20 = 80 and 100 x .8 = 80
But if the shirt cost $35, 35-20 = 15 while 35 times .8 = 28
This shows that the cost of the shirt is important in discovering which coupon is better.

On the map the distance between two towns is 10.5 centimeters. If 3 centimeters represents 90 miles what is the actual distance between the cities in miles?
Answer: 315 miles
Step-by-step explanation: First divide 10.5 and 3.
10.5 / 3 = 3.5
Then multiply that by 90.
3.5 x 90 = 315
The actual distance in miles between the cities is 315 miles.
Given,
On the map the distance between two towns is 10.5 cm.
If 3 cm represents 90 miles what is the actual distance between the cities in miles?
How to compare two quantities?We need to multiply in such a way that we get the required expression in one side of the equation.
Example:
If 9 apples in 3 baskets.
9 apples = 3 basket.
In 2 basket we have,
3 basket = 9 apples
Multiply 2/3 on both sides.
2/3 x 3 basket = 2/3 x 9 apples
2 basket = 6 apples.
We have,
Distance between two towns = 10.5 cm
3 cm represents 90 miles.
We can write it as:
3 cm = 90 miles
Multiply 10.5/3 on both sides
10.5/3 x 3 cm = 10.5 / 3 x 90 miles
10.5 cm = 10.5 x 30 miles
10.5 cm = 315 miles
Thus the actual distance in miles between the cities is 315 miles.

The initial pressure inside a closed container is 200 psi. As the temperature inside the container increases, the pressure increases. If the pressure increases 7.5 psi for each degree Fahrenheit of increased temperature, which equation best represents p, the pressure inside the container after the temperature has increased t degrees?
Answer:
p = (200 + 7.5t) psi
Step-by-step explanation:
The initial pressure inside a closed container is 200 psi. Since the container is closed, the pressure inside it can not be less than 200 psi.
The pressure increases 7.5 psi with a degree rise in temperature (t) = 7.5t
so that;
p = 200 + 7.5t
= (200 + 7.5t) psi
If the temperature increases by [tex]1^{o}[/tex] F, then;
p = 200 + 7.5(1)
= 200 + 7.5
= 207.5 psi
If the temperature increases by [tex]10^{o}[/tex] F, then;
p = 200 + 7.5(10)
= 200 + 75
= 275 psi

Moretti's Ristorante & Pizzeria has two different soda sizes, Regular and Large. The Regular size soda is 22 ounces and the Large soda is 64 ounces. By what percent does the amount of soda increase between the different soda sizes? Round to the nearest percent
Answer:
280
Step-by-step explanation:
Given that:
The two different sizes of soda are:
Regular = 22 ounce
Large = 62 ounce.
The objective is to determine by what percent does the amount of the soda increase between the different soda size.
i.e. The ratio of the larger size in respect to the regular size:
So,
62/22 = 2.82
Thus in percent, the amount of the soda increase between the different soda size = 2.82 × 100%
= 282 percent
To the nearest percent, it is = 280
