and the width is increased by 40%. Calculate
the percentage change in the area of the
rectangle.
Answer:
Step-by-step explanation:
given.quesion.
The length of a rectangle is decreased by 25% and the width has increased by 40% calculate the percentage change in the area of the rectangle
to. find.
area of the rectangle
given
decreased. 25•/•
increased.40•/•
solusion
Length = L
Breadth = B
Original area = L x B
New area = A = L x (1 - 25%) x B x (1 + 40%)
A = L x B x 0.75 x 1.40 = L x B x 1.05
Therefore the area of the rectangle has increased by 5%.

AAS
Previous
Answer:
AAS
Step-by-step explanation:
Answer:
Angle-side-angle is a rule used to prove whether a given set of triangles are congruent.
The ASA rule states that:
If two angles and the included side of one triangle are equal to two angles and included side of another triangle, then the triangles are congruent.
Angle-Angle-Side (AAS) Rule
Angle-side-angle is a rule used to prove whether a given set of triangles are congruent.
The AAS rule states that:
If two angles and a non-included side of one triangle are equal to two angles and a non-included side of another triangle, then the triangles are congruent.
In the diagrams below, if AC = QP, angle A = angle Q, and angle B = angle R, then triangle ABC is congruent to triangle QRP.

Step-by-step explanation:
Al precio de un producto se le aplica un descuento del 30% y al nuevo precio otro descuento del 30% cual es el descuento total?
Answer:
The total discount is 51%.
Step-by-step explanation:
A 30% discount is applied to the price of a product and another 30% discount to the new price. What is the total discount?
Let the price is p.
After first discount, the price is
= 70% of p = 0.7 p
After second discount, the price is
= 70% of 0.7 p
= 0.7 x 0.7 p
= 0.49 p
So, let the total discount is d.
[tex]d = \frac{p - 0.49 p}{p}\times 100 = 51%[/tex]

25+ POINTS WILL MARK BRAINLIEST
Answer:
Step-by-step explanation:
perimeter of rectangle=a+b+c
=3x+3x+15
=6x+15
if perimeter of rectangle is 90,
perimeter=a+b+c
90=3x+3x+15
90-15=6x
75/6=x
12.5=x
Answer:
X=12.5
Step-by-step explanation:
3x+3x+15
If it equalls 90 then write it as 6x+15=90
Now isolate X.
6x+15=90
6x=75
x=12.5
CHECK UR WORK
(3*12.5)+(3*12.5)+15=90
37.5+37.5+15=90
75+15=90

Given:
A figure of a rectangular prism with length l, width w and height h.
To find:
The surface area of the rectangular prism.
Solution:
The product of twice of the length l and the width w is:
[tex]2\times l\times w=2lw[/tex] ...(i)
The product of twice of the length l and the height is:
[tex]2\times l\times h=2lh[/tex] ...(ii)
The product of twice of the width w and the height h is:
[tex]2\times w\times h=2wh[/tex] ...(iii)
The surface area of the prism is the sum of (i), (ii) and (iii). So, the expression for the surface area is:
[tex]A=2lw+2lh+2wh[/tex]
[tex]A=2(lw+lh+wh)[/tex]
Therefore, the required expression is [tex]2(lw+lh+wh)[/tex].

Step-by-step explanation:
2w+2019 = 15w + 1838
Answer:
181/13 =w
Step-by-step explanation:
2w+2019 = 15w + 1838
Subtract 2w from each side
2w-2w+2019 = 15w-2w + 1838
2019 = 13w + 1838
Subtract 1838 from each side
2019 -1838 = 13w
181 = 13w
Divide each side by 13w
181/13 = 13w/13
181/13 =w

Complete question is;
Craig went to an auction and bought five different items. Use the clues below to determine the price he paid for each item.
1. the chair was the most expensive item, which sold for $95.
2. The range of the prices of the five items was $75.
3. The stereo was the least expensive item.
4. Craig bought the TV for $25.
5. The video game player was $20 more than the TV.
6. The bed was $60 more than the stereo.
Answer:
Cost of chair = $95
Cost of stereo = $20
Cost of TV = $25
Cost of video game player = $45
Cost of bed = $80
Step-by-step explanation:
We are told the chair was the most expensive item which was $95.
the range of the prices of the five items was $75. This means;
Highest price - lowest price = $75
Since highest price is $95, then lowest price = 95 - 75 = $20
stereo is the least expensive item. Thus, stereo will cost $20.
TV was bought for $25
video game player was $20 more than the TV. Thus, video game player cost = 25 + 20 = $45
Bed was $60 more than stereo. Thus,
Cost of bed = $20 + $60 = $80

Jaiver bought a new TV for 479.76. He will make equal payments each month for 2 years . Estimate each payment.
Answer:
$19.99
Step-by-step explanation:
There are 12 months in a year, so in 2 years, there are 24 months.
Find how much each payment will be by dividing the cost by 24:
479.76/24
= 19.99
So, each payment will be $19.99
A hotel manager records the number of bookings made at various prices during July.
Answer:
C. strong negative correlation
Step-by-step explanation:
A hotel manager records the number of bookings made at various prices during July.
What type of correlation does the graph show?
A. strong positive correlation
B. weak positive correlation
C. strong negative correlation
D. weak negative correlation
Correlation is a statistical measure used to measure the relationship that exists between two variables.
1. Positive correlation : it mean that the two variables move in the same direction. If one variable increases, the other variable also increases.
For example, there should be a positive correlation between quantity supplied and price
When there is a positive correlation, the graph of the variables is upward sloping
2. Negative correlation : it mean that the two variables move in different direction. If one variable increases, the other variable decreases.
For example, there should be a negative correlation between quantity demanded and price
When there is a negative correlation, the graph of the variables is downward sloping
3. Zero correlation : there is no relationship between the variables
help with this question please and thanks in advance
A T.V. is regularly priced at $600, but it is on sale for 20% off. What's the sale price?
Answer:
$480
Step-by-step explanation:
multiply the normal price $600 by 20 then divide it by one hundred
the discount is $120
the sales price is subracting the discount of $120 from the original price of $600 then get $480 as the sales price.
Answer:
Step-by-step explanation:
Method 1: Subtract 20% from 100%, obtaining 80%, and then multiply the regular price ($600) by the decimal equivalent 0.80. We get $480 as the sale price.
Method 2: Calculate the amount of the discount by multiplying $600 by 0.20, obtaining $120. Then subtract this discount from the regular price, $600, obtaining $480.

Corresponding parts of similar triangle have the same proportions
Answer: A) [tex]\frac{AB}{XY} =\frac{AC}{XZ}[/tex]
Step-by-step explanation:
OK so if a figure is a dilation of another figure that means that is has the same angles but the sides are going to be smaller or bigger. Even though the sides are a different size they are proportional. So if I divided the length of AB over XY I'd get 5 since that is the scale factor. If I did that with AC over XZ I'd get 5 again because that is the scale factor. That's because they were proportional. Let's say this wasn't a dilation and AB over XY was 5 but AC over XZ was 4 that would mean it isn't proportional because AB would be 5 times bigger but XZ is only 4 times bigger.
