Marissa is going food shopping with her mother for a variety of items. In order to save money, they must decide which food is the best buy. $ 4.75 for 18 oz. And 11.29 for 40 oz. $________ per ounce $________ per ounce
Answer:
$0.26388 per oz ; $0.28225 per oz
Step-by-step explanation:
Given :
Option 1:
$4.75 for 18 oz
Option 2:
$11. 29 for 40 oz
The price per ounce (oz) for each option is :
Price / number of ounce
Option 1:
4.75 / 18 =
Price per ounce = $0.26388 per oz
Option 2:
$11.29 / 40 oz
= $0.28225 per oz
Please Answer! This is urgent!
Step-by-step explanation:
If the perimeters could be equal,
then 4(x + 3) = 2(x + 4 + x + 1).
=> 4x + 12 = 2(2x + 5)
=> 4x + 12 = 4x + 10
However 12 =/= 10 for all real values of x. Hence their perimeters can never be equal.

Linear and nonlinear definition please help!!!
Answer:
Linear means something related to a line. All the linear equations are used to construct a line. A non-linear equation is such which does not form a straight line. It looks like a curve in a graph and has a variable slope value
Step-by-step explanation:
Please brainiest
Answer:
Linear means something related to a line that makes a straight line.A non-linear equation is such which does not form a straight line aka makes a curved or zigzag line.
3. Find the slope and y-intercept of the graph of the following equation.
2y + 4 = -6x
Answer:
slope= -3,y - intercept y = -2
Step-by-step explanation:
- Make y the subject by taking four on the opposite side of the equal sign.
2y = -6x - 4
- Divide throughout by 2 and from there you get the gradient which is also the slope.
- To get the y - intercept,the value of x =0. Thus you get y =-2.

Answer:
It will be 57-2.5h=32
This is because you're starting with 57 degrees. 2.5 is constant so that is why you need a variable for it.
Answer:
I would say 57 - 2.5h = 32
Step-by-step explanation:
Because the temperatures is dropping so that why we are subtracting and we don't no how many hours are theirs every time it drops for 2.5 that why we put the h with the 2.5

Answer:
About 527.79
Step-by-step explanation:
formula is A=2πrh+2πr^2
Answer:
[tex]527.52\:\mathrm{in^2}[/tex]
Step-by-step explanation:
The surface area of this cylinder consist of two circles and a 3D outer edge with respect to the circumference. The area of a circle is given as [tex]r^2\pi[/tex]. Using [tex]\pi=3.14[/tex] as requested in the problem, the area of both these circles is:
[tex]2\cdot6^2\cdot 3.14=226.08\:\mathrm{in^2}[/tex].
The area of the outer edge is the circumference of the circle multiplied by the height. The circumference of a circle is given by [tex]2r\pi[/tex].
Therefore, the circumference's 3D outer edge is:
[tex]8\cdot2\cdot6\cdot 3.14 = 301.44\:\mathrm{in^2}[/tex].
Adding these up, the total surface area is:
[tex]226.08+301.44=\fbox{$527.52\:\mathrm{in^2}$}[/tex].
Cora went on a shopping trip to Lowell. She purchased a calculator originally priced at $75 but discounted 20%. If sales tax in Lowell is 15%, what was the total cost?
Answer: $69
Step-by-step explanation:
Sales tax is charged after the discount.
The calculator was originally $75 and there is a 20% discount.
The discounted price is:
= 75 * (1 - 20%)
= 75 * 0.8
= $60
Now the sales tax applies. Total cost is:
= 60 * (1 + 15%)
= 60 * 1.15
= $69

A salesman has a car for sale for $5000. He decides to increase the price by 40%. When no one buys the car, he decreases the new price by 10%.
What is the final price of the car?
Answer:
$6300
Step-by-step explanation:
original price: $5000
increase price by 40%: $5000×1.4=$7000
decrease new price by 10%: %7000×0.9=$6300

Solve the following systems by Elimination
1) 4x+6y=32
3x-6y=3
2) -3+5y=-11
3x+7y=-1
Answer:
The solutions for both system of equations are as follows:
(5,2)(2,-1)Step-by-step explanation:
The first set of equations is:
[tex]4x+6y=32\\3x-6y=3\\[/tex]
It can clearly be seen that the coefficients of y are already same in magnitude with different signs so we have to add both equations
So adding both equations, we get
[tex]4x+6y+3x-6y = 32+3\\7x = 35\\\frac{7x}{7} = \frac{35}{7}\\x = 5[/tex]
Putting x=5 in equation 1
[tex]4(5)+6y = 32\\20+6y = 32\\6y = 32-20\\6y = 12\\\frac{6y}{6} = \frac{12}{6}\\y = 2[/tex]
The solution is (5,2)
The second set of simultaneous equations is:
[tex]-3x+5y=-113x+7y=-1[/tex]
We can see that the coefficients of x in both equations are same in magnitude with opposite signs so
Adding both equations
[tex]-3x+5y+3x+7y = -11-1\\12y = -12\\\frac{12y}{12} = \frac{-12}{12}\\y = -1[/tex]
Putting y= -1 in first equation
[tex]-3x+5(-1)=-11\\-3x-5=-11\\-3x=-11+5\\-3x=-6\\\frac{-3x}{-3} = \frac{-6}{-3}\\x = 2[/tex]
The solution is: (2,-1)
Hence,
The solutions for both system of equations are as follows:
(5,2)(2,-1)Whats the value? of this equation
Answer:
Option (4)
Step-by-step explanation:
Given equation of the linear graph is,
[tex]y=-\frac{5}{8}x+\frac{2}{3}n[/tex]
By comparing this equation with the slope-intercept form of the linear equation,
y = mx + b
m = [tex]-\frac{5}{8}[/tex]
And b = [tex]\frac{2}{3}n[/tex]
Since, y-intercept 'b' = -12 [given]
[tex]\frac{2}{3}n=-12[/tex]
n = [tex]-12\times \frac{2}{3}[/tex]
n = -8
Therefore, Option (4) will be the answer.
Given that

leah makes a guaranteed salary of $200 per week. but is paid commission of 15% of total sales per week. how much would leah make in a week in which she made $225 in sales?how much would leah make in a week if she made x dollars in sales
Answer:
Total earned with $225 sales = $233.75
Total earned with x sales = 0.15x+200
Step-by-step explanation:
Given that:
Base salary of Leah per week = $200
Commission paid = 15%
Sales made by Leah = $225
Commission = 15% of 225
Commission = [tex]\frac{15}{100} * 225[/tex]
Commission = 0.15 * 225
Commission = $33.75
Total earned = 200 + 33.75 = $233.75
Commission when sales are x
Commission = 0.15x
Total earned = 0.15x+200
Hence,
Total earned with $225 sales = $233.75
Total earned with x sales = 0.15x+200
