A car is purchased for £11 500 In its first year, the value of the car will depreciate by 15%. Each year after that, the value of the car will depreciate by 10%. What is the value of the car at the end of 3 years?
Answer:
Value of the car at the end of 3 years is £7917.75
Step-by-step explanation:
The car is purchased for £11500.
In the first year, 15% depriciation.
So, depreciation on first year =11500 *[tex]\frac{15}{100}[/tex] =1725
After first year depreciation the value of car =11500-1725 =£9775
Now, second year depreciation is 10%
So, 10% of 9775 =0.10*9775 =977.5
Value of car after 2 years = 9775 -977.5 =8797.5
Now, for third year depreciation is 10%.
So, depreciation on 3 year = 10% *8797.5
=0.10*8797.5
=879.75
So, value of car after 3 years = 8797.5 -879.75 =£7917.75
Solve the system of equations by substitution.
3x+2y=10 y=3x-4
x= y=
Answer:
x=2; y=2
Step-by-step explanation:
3x+2y=10
y=3x-4
We can substitute y from the first equation with the second equation:
3x+2(3x-4)=10
3x+6x-8=10
9x=18
x=2
Now plug this in to any of the equations (i used second equation):
y=3(2)-4
y=6-4
y=2
Check your answers:
y=3x-4
2=3(2)-4
2=6-4
2=2

and some granola bars for $2.50
each. How many granola bars did he
buy if he spent $11 total?
Answer:

Step-by-step explanation:
x is the number of granola bars
1 + 2.5x = 11
2.5x = 10
x = 4
James buys a shirt and a pair of socks on sale for 20% off. If the price of the shirt
before the sale was $26 and he spent a total of $26, what was the original price of
the socks? Round to the nearest hundredth, if necessary.
Answer:
The Price of socks is
=
$
8
Explanation:
Given -
Discount 25%
Price of shirt before discount
=
$
24
Amount spent on both shirt and socks after applying discount
=
$
24
Assume the price of socks
=
$
x
Then Shirt + Socks before discount =

(

After discount one has to pay 75% of the article.
Then -

How to verify your answer -
One way
Price of shirt =$24
Price of socks =$8
Total =$32
Discount =25%
Discount for $32 is

Amount one has to pay after discount

Another way is -
Discount 25%
It means after discount it is enough if he pays 75% of the price.
In our case - Actual price is

Step-by-step explanation:
p(x)= 4x^3 -3x^2+5x-2
Answer:
p=4x^3−3x^2+5x−2/x
Step-by-step explanation:
Let's solve for p.
px=4x^3−3x^2+5x−2
Step 1: Divide both sides by x.
px/x=4x^3−3x^2+5x−2/x
p=4x^3−3x^2+5x−2/x
Answer:
p=4x^3−3x^2+5x−2/x

Can you answer plz
у = х + 3
у =-2x-3
Answer:
x = - 2, y = 1
Step-by-step explanation:
Comparing both the equations,
→ y = y → x + 3 = - 2x - 3
=> x + 3 = - 2x - 3
=> x + 2x = - 3 - 3
=> 3x = - 6
=> x = - 6/3 = - 2
Substitute the value of x in any of these:
=> y = x + 3 = - 2 + 3 = 1
Answer:
Step-by-step explanation:
If a solution exists for the system of equations y=y so we can say
x+3=-2x-3 Add 2x to each side
3x+3=-3 Subtract 3 from each side
3x=-6. Divide each side by 3
x=-2, since y=x+3
y=-2+3
y=1
So the solution to the system of equations is the point (x,y)=(-2,1)
The set for a school play needs a replica of a historic building painted on a backdrop that is 20 feet long and 16 feet high. The actual building measures 320 feet long by 256 feet high. A stage crewmember writes (x, y) arrow right ( 1/20 x, 1/20y) to represent the dilation. Is the crewmember's calculation correct if the painted replica is to cover the entire backdrop? Complete the explanation.
Answer:
Stage crewmember's calculation is incorrect
Correct = 1/16x 1/16y
Step-by-step explanation:
Given that:
Dimension of backdrop : 20 feets long ; 16 feets high
Actual dimension of building : 320 feets long ; 256 feets high
The correct scale factor can be obtained thus :
Ratio of backdrop dimension to the actual dimension of building
Length : 20 / 320 = 1 /16
Height : 16 / 256 = 1/16
Hence, stage crewmember's calculation of (1/20x ; 1/20y) is incorrect.

Answer:
31.5
Step-by-step explanation:
First we want to find what side NP is equal to. To do that we divide 4 by 12
12/4=3 so side mp=3
next we want to find the scale factor of the rectangles. to do that we divide 4 from 9
9/4=2.25
next we want to find what side st is equal too
to do that we multiply 3 by 2.25
3x2.25=6.75
finally we want to find the perimeter and to do that we do 2(6.75)+2(9)
2(6.75)+2(9)=31.5 so the perimeter of rectangle RSTU is 31.5
hope this helps :)
