850 x 0.75^3 = $358.59
answer: $358.59
Answer: $358.59
Step-by-step explanation:
[tex]$$After one year the laptop computer's price is:$$\begin{aligned}&=\$ 850-\$ 850 \times 25 \% \\&=\$ 850-\$ 212.5 \\&=\$ 637.5\end{aligned}$$[/tex]
[tex]$$ Again two year the computer's price is:$$\begin{aligned}&=637.5-25 \% \text { of } 637.5 \\&=637.5-159.375 \\&=\$ 478.125\end{aligned}$$[/tex]
[tex]\bold{\text { So a fair price for the computer is } \$ 358.59}[/tex]
[tex]\begin{aligned}\\\bold{Or}\text { Simply Calculate as } &=(\text { Purchase price }) \times(1-25 \%)^\text{time} \\&=850 \times(1-0.25)^{3} \\&=850 \times(0.75)^{3} \\\bold{&=\$358.59}\end{aligned}[/tex]

if 6 people share 31 apples equally, how many apples should each person get ?
Answer:
5 apples
Step-by-step explanation:
[tex]\frac{31}{6}=5.16666667[/tex]
Since the problem asks for how many apples, you'll have to round down the number you get. 5.16666667 rounded down gives you 5 apples each.
The original price is $125. The sale price is $81.25. How much was the discount as a percent?
Answer: 35%
Step-by-step explanation:
Start by subtracting the original price by the sale price.
125-81.25=43.75
Now divide that amount by the original price.
[tex]\frac{43.75}{125} =0.35[/tex]
Multiply that value by 100 for the answer
0.35×100=35
35%
Answer:
Discount Percent = 35.00 %
Step-by-step explanation:
125-81.25=43.75 actual discount
43.75/125 = 0.35 actual discount / original
0.35 as percentage = 35%

Step-by-step explanation:
Given information:
Malik can spend no more than $24 to buy pecans and cashews.Malik wants to buy at least 3 pounds of nuts.Cost of pecans = $6 per poundCost of cashews = $8 per poundDefine the variables:
Let x = number of pounds of pecans Malik can buy
Let y = number of pounds of cashews Malik can buy
Create a system of inequalities from the given information:
6x + 8y ≤ 24x + y ≥ 3Graph the inequalities (see attached)
The possible solutions are any points enclosed by the shaded area where x > 0 and y > 0.
Therefore, two possible combinations are:

The algebraic expression of the SUM is n²+2n. What is the common difference and first term
Answer:
see explanation
Step-by-step explanation:
substitute n = 1, 2 into the sum rule
1² + 2(1) = 1 + 2 = 3 , then
a₁ = 3
2² + 2(2) = 4 + 4 = 8 , then
a₁ + a₂ = 8
3 + a₂ = 8 ( subtract 3 from both sides )
a₂ = 5
then
common difference d = a₂ - a₁ = 5 - 3 = 2
First term is 3 and common difference = 2

Answer:
18 kilometers
Step-by-step explanation:
if you know the perimeter, then all you have to do is add up what you have, 10+7=17 and then subtract it giving you the bits that you dont know, so 35-17=18 kilometers.
Answer:
s = 9 Km
Step-by-step explanation:
the perimeter is the sum of the 4 sides
given perimeter = 35 , then
10 + 7 + s + s = 35
17 + 2s = 35 ( subtract 17 from both sides )
2s = 18 ( divide both sides by 2 )
s = 9 Km

Answer:
9/12 (or 3/4)
Step-by-step explanation:
If you subtract the number of brownies that Brittany's brother will eat, you will have 9 remaining brownies. So, that means 9 out of the original 12 brownies will be left, or 9/12. Also, you can simplify the fraction. Both 9 and 12 can be divided by 3.
9/12 divided by 3/3 equals 3/4. 3/4 is the fraction in it's simplest form.
So, 9/12 (or 3/4) of the brownies are left.
I hope this helps! Have a lovely day!! :)

Answer:
t = 3 seconds
Step-by-step explanation:
You can think of this as a quadratic and find the zeros. i will use x and y to make it easier.
y = -16x^2 + 48x
y = (x)(-16x+48)
y = (-16)(x)(x-3)
This means your zeros are at x = 0 and x-3 = 0, so 0 and 3.
0 is when the ball leaves the ground, so 3 is when it returns.

Answer:
3/2
Step-by-step explanation:
To find the slope, choose two points.
For example, choose (2, 5) and (4, 8).
Now find the difference between the y-coordinates.
8 - 5 = 3
Find the difference between the x-coordinates.
4 - 2 = 2
Divide the difference in y by the difference in x. That is the slope.
slope = 3/2

What value of x makes this equation true?
5x+3=2x-3
Answer:
-2
Step-by-step explanation:
[tex]5x+3 = 2x -3 \\\\\implies 5x -2x = -3 -3\\\\\implies 3x = -6\\\\\implies x = -\dfrac 63 =-2[/tex]
Let's solve this equation.
Step 1
Move the numbers to the right:-
5x=2x-3-3
Step 2
Move the x's to the left
5x-2x=-3-3
Notice I use the opposite operation :)
Step 3
Combine like terms
3x=-6x
Step 4
Divide both sides by 3
x=-2
That's the value of x that makes the equation true.
note:-Hope everything is clear; if you need any clarification/explanation, kindly let me know, and I'll comment and/or edit my answer :)

Have you ever seen a photo online that did not seem to have the colors right? Perhaps the colors looked unnatural or not appropriate for the subject of the photo. Describe such a photo and what you think was wrong with it in terms of color. How did this photo with poor color values make you feel about the website it was on? How important do you think getting the color right is for images online?
Write three to five sentences that answer these questions. You should thoroughly explain every statement you make in your response. If possible, include a link to the photograph you are describing.
Answer:
Yes, I have before. The colors were pretty natural, but they didn't quite fit with the actual picture. It was a street with blue vintage contrast, and it had a rotting apple core. It was wrong because blue street didn't feel that normal and was an inaccurate portrayal because it didn't fit the apple core and all. The website actually was a website with "bad" photos, so I understood. I think it is very important to accurately convey meaning, tone, and much more.

The surface area of a cylinder is about 155.83 square feet. The height of the cylinder is 3 times the radius. What are the height and the diameter of the cylinder, to the nearest hundredth of a foot?
The radius is approximately___ feet and the height is approximately___feet.
The diameter and height of the cylinder are 4.98ft and 7.47 feet respectively
How to calculate the surface area of a cylinderThe formula for calculating the surface area of a cylinder is expressed as:
S = 2πr(r+h)
where
r is the radius
h is the height = 3r
Substitute into the expression to have:
S = 2πr(r+3r)
S = 2πr(4r)
S = 8πr²
155.83 = 8πr²
r = 2.49feet
Since h = 3r
h = 3(2.49)
h = 7.47 feet
Hence the diameter and height of the cylinder are 4.98ft and 7.47 feet respectively

Answer:
4πx² square units
Step-by-step explanation:
Area of a circle
[ A = πr² ]The formula uses the radius of the circle, but we have the diameter. Remember the relation :
Diameter = 2 x Radius4x = 2 x RadiusRadius = 4x/2 = 2xNow, we can solve.
