Reena bought a jacket for £45 . six months later ,she sold it for £34.65.What was her percentage loss?
When Reena bought a jacket for $45 and after six months later she sold it for $34.65, then the percentage loss is 25%
Given,
Reena bought a jacket for = $45
Selling price of jacket = $34.65
Here, selling price is lower than cost price, so we can consider it as loss
We know,
Loss percentage = (Loss / Initial cost)×100
Loss = Initial cost - Selling price
Loss = 45 -34.65= $10.35
Loss percentage =[tex](\frac{10.35}{45}) 100[/tex]
=0.25×100
=25%
Hence, when Reena bought a jacket for $45 and after six months later she sold it for $34.65, then the percentage loss is 25%

Given right triangle ABCABC with altitude \overline{BD} BD drawn to hypotenuse ACAC. If AD=3AD=3 and AC=12,AC=12, what is the length of \overline{AB}? AB ? (Note: the figure is not drawn to scale.)
Answer:
The answer is "6"
Step-by-step explanation:
[tex]\to x^2 = 3 \times 12 \\\\\to \sqrt{6^2 +3^2} = \sqrt{45} =\sqrt{9} \sqrt{5} = 3\sqrt{5} \\\\\to x= 6[/tex]
The value of [tex]\overline{AB} =6[/tex]
A book has a font and a back and 400 pages. The front and back cover are each 0.9mm thick, measured to 1 decimal place. Each page is 0.13mm thick measured to 2 decimal places calculate the minimum thickness of the book
Answer:
53.8 mm
Step-by-step explanation:
Front page and a back page + 400 pages.
The front and back cover are each 0.9mm thick, measured to 1 decimal place.
Total thickness of front and back page = 0.9mm × 2
= 1.8 mm
Each page is 0.13mm thick measured to 2 decimal places
Total number of pages = 400
Total thickness of the pages = Thickness of each page × Total number of pages
= 0.13mm × 400
= 52 mm
minimum thickness of the book = Total thickness of front and back page + Total thickness of the pages
= 1.8mm + 52mm
= 53.8 mm
The minimum thickness of the book is 53.8 mm

During an online sale, you buy three sweatshirts and two pairs of sweatpants for $85.50. Later you buy three more sweatshirts and four more pairs of sweatpants for $123. (You can never have too many sweats during a pandemic). What is the sale price of each sweatshirt and each pair of sweatpants?
Answer:
Step-by-step explanation:
let
x = price of a sweatshirt
y = trice of sweatpants
three sweatshirts and two pairs of sweatpants for $85.50
3x + 2y = 85.50
three more sweatshirts and four more pairs of sweatpants for $123
3x + 4y = 123
by solving the system of equations
3x + 2y = 85.50
3x + 4y = 123
we find
x = $16
y = $18.75

y = -5x
When x = -2 ; y = -5* (-2) = 10 ; (-2 , 10)
When x = -1 ; y = -5 *(-1) = 5 ; (-1 , 5)
When x = 0 , y = 0 ; (0 , 0)
When x = 1 ; y = -5 *1 = -5 ; (1 , -5)
When x = 2 ; y = -5 *2 = -10 ; (2 , -10)
Mark these points (-2 , 10) , (-1 , 5) , (0 , 0) , (1 , -5) , (2 , -10) and join them.
The price of Nintendo Switch was reduced from $300 to $240 during a
Black
Friday sale. By what percentage was the price of the gaming system
reduced?
Answer:
20% or .2
Step-by-step explanation:
First divide 240 by 300
240/300
this gives you .8, you would then subtract that from 1 to get .2
You can check your answer by multiplying 300 by .2
300*.2
this gives you 60 which is the difference between the 2 numbers

7x−3y=20
y=5x−4
x=
y=
Answer:
Step-by-step explanation:
substitute the value of y in the first equation.
7x-3(5x-4)=20
7x-15x+12=20
-8x=20-12
x=8/-8
x= -1
then you substitute the value of x on the y equation to find y
y=5×-1 -4
y= -5-4
y= -9
Answer:
x = -1, and y = -9
Step-by-step explanation:
This is done by solving one of the two equations for x or y, then substituting it in place of that variable in the other equation.
Since y is already clearly defined in the second equation let's go with that:
[tex]Given\ 7x - 3y = 20,\ and\ y = 5x - 4[/tex]
[tex]7x - 3(5x - 4) = 20[/tex]
[tex]7x - 15x + 12 = 20[/tex]
[tex]7x - 15x = 20 - 12[/tex]
[tex]-8x = 8[/tex]
[tex]x = -1[/tex]
Now we can replace x in the equation for y with -1:
[tex]y = 5(-1) - 4[/tex]
[tex]y = -5 - 4[/tex]
[tex]y = -9[/tex]
To make sure our answers are correct, let's substitute them into the original equations:
[tex](-9) = 5(-1) - 4\\-9 = -5 - 4\\-9 = -9[/tex]
Good, let's test the other equation
[tex]7(-1) - 3(-9) = 20\\-7 - (-27) = 20\\-7 + 27 = 20\\20 = 20[/tex]
So we know that our answer is correct.
