A student saves money to buy a laptop. The student already has 307.50 saved and puts aside $100 each month to help pay for the laptop. After 5 months, the total amount saved is 75% of the total cost of the laptop. How much more does the student need to save to buy the laptop rounded to the nearest cent.
Answer:
The amount the student needs to save is approximately $269.167
Step-by-step explanation:
The amount the student already has saved for his laptop = $307.50
The amount the student puts aside each month to pay for the laptop = $100
The total amount saved after 5 months = 75% of the total cost of the laptop
Therefore, we have;
The total amount the student has after 5 months = $307.5 + 5 × $100 = $807.5
The total amount saved after 5 months = 75% of the total cost of the laptop
Therefore;
$807.5 = 75% of the total cost of the laptop
The total cost of the laptop = $807.5/75% = $807.5/75 × 100 = [tex]\$ \ 1076\frac{2}{3}[/tex]
The total cost of the laptop ≈ $1076.67
Therefore;
The amount the student needs to save = $1076.67 - $807.5 = [tex]\$ \ 269\frac{1}{6}[/tex]
The amount the student needs to save ≈ $269.167.

Which equation best represents the line graphed above?
A) y=2
B) y= x + 2
C) y=2x
D) x= 2
Answer:
x = 2
Step-by-step explanation:
The line goes straight through the x axis
Answer: x=2
Step-by-step explanation:
The line goes up and down, which is, Horizontal and Vertical Lines
Vertical lines go up and down and have a slope that is undefined. Graphs of horizontal lines are parallel to the x-axis. Graphs of vertical lines are parallel to the y-axis.

Sam can make 15 pizzas in two and a half hours. At this rate, how many pizzas can Sam make in 8 hours
Answer:
Sam can make 48 pizzas.
Step-by-step explanation:
Sam is making three pizzas every thirty minutes. Since eight hours is equivalent to 16 sets of 30 minutes, you have to multiply 3x16, which equals 48.
(4) Abdi has two electric train sets: A and B. Each train is on its own circular track. He starts both trains at the same time. Train A returns to its starting point every 12 seconds. Train B returns to its starting point every 9 seconds. If the trains continue traveling, what is the least amount of time, in seconds, that both trains will arrive at the starting points at the same time?
Answer:
The least amount of time both trains will arrive at the starting points at the same time is 36 seconds.
Step-by-step explanation:
From the question, Train A returns to its starting point every 12 seconds and Train B returns to its starting point every 9 seconds.
First, we will determine the times the trains will return to the their starting points.
For Train A,
The second time Train A will return to its starting point will be at 24 seconds,
The third time will be at 36 seconds
The fourth time will be at 48 seconds and so on.
For Train B,
The second time Train B will return to its starting point will be at 18 seconds,
The third time will be at 27 seconds
The forth time will be at 36 seconds and so on.
Since both trains arrive at their starting points at 36 seconds,
Hence, the least amount of time both trains will arrive at the starting points at the same time is 36 seconds.

expand and simplify 3(2x+1)+2(x+4)
Answer:
8x+11
Step-by-step explanation:
1. 6x+3+2x+8
2. 8x+11
Answer:
8x + 11
Step-by-step explanation:
3(2x+1)+2(x+4)
distribute the 3 & 2 within the parentheses. first, multiply 3 and 2x, then multiply 3 and 1 to get 6x + 3. next, multiply 2 and x, then multiply 2 and 4 to get 2x + 8. this gives you:
6x + 3 + 2x + 8
then add like terms (6x + 2x and 3 + 8) to get your simplified final answer:
8x + 11

Juan's class is going to construct an outdoor garden. The garden will be in the shape of a square, Juan's teacher gave the class three
options for the area of the garden: 30 square feet, 40 square feet, or 50 square feet.
Part A
Without using a calculator, approximate the side length, to the nearest tenth of a foot, for the garden with an area of 30 square fet. Show
your work.
Part B
The other two garden options have approximate side lengths of 6.3 feet and 7.1 feet. Locate and graph the three points on a horizontal
number line to show the approximation of the side length for each option.
Answer:
Part A: 5.5
Part B: Kindly refer to the attached image for the number line representation.
Step-by-step explanation:
Given that:
Possible area of the first garden = 30 sq ft
Possible area of the second garden = 40 sq ft
Possible length of the second garden = 6.3 ft
Possible area of the third garden = 50 sq ft
Possible length of the third garden = 7.1 ft
To find:
Part A: Side length of the square with area 30 sq ft to the nearest tenth.
Part B: Locating and graphing the three points on a horizontal number line.
Solution:
Formula for area of a square:
[tex]Area =(Side)^2[/tex]
Part A: Given that area = 30 sq ft
Putting in the formula to find the value:
[tex]30=Side^2\\\Rightarrow Side = 5.477 \approx \bold{5.5\ ft}[/tex]
Part B:
Kindly refer to the attached image for the number line representation of the given two lengths and the length calculated for the first square.
The three lengths are 5.5, 6.3 and 7.1 respectively.
The three numbers to located on the graph are = 5.5, 6.3 and 7.1

Dante is making a necklace with 18 rows of tiny beads in which the number of beads per row is given by the series 2 + 8 + 14 + 20 + ...
a. Use sigma notation to write the series. Explain what the numbers in the sigma notation represent in this situation and how you found the expression used in the summation.
b. Find the total number of beads in the necklace. Explain your method for finding the total number of beads.
Answer:
Step-by-step explanation:
Well, first we are going to add the beads together.
2 + 8 + 14 + 20 = 44
Next, let's multiply the sum by 18 because there are 18 rows of 44 beads.
18 x 44 = 792
I hope this answer helps. I not sure how to solve the sigma notation part, but there is the solving part. ;)
4y + 3x = 5 solve for x
Answer:
Move all terms that don't contain x to the right side and solve.
x = 5 /3 − 4 y /3
Answer:4y+3x=5
Step 1: Add -4y to both sides.
3x+4y+−4y=5+−4y
3x=−4y+5

pearl will put wire around a rectangular lot with a width of 20m and a length that is two times its width.how many mters of wire will she need?
Answer: 120m
Step-by-step explanation:
Width = 20m
Length = 2 × width
= 2 × 20m
= 40m
We've to calculate the perimeter
Perimeter = 2(length + Breadth)
= 2(20m + 40m)
= 2(60m)
= 120m
