Answer: Priya enjoyed a 40% discount

Step-by-step explanation:

The key information in the question:-

*** The normal cost of a pair of earrings is $22

*** Priya eventually purchased the pair of earrings for only $13.20

*** We are required to calculate the percentage discount.

Discount generally refers to the reduction from the usual price of something. In this scenario, since Priya bought the pair of earrings for only $13.20 instead of the usual $22, the discount that Priya enjoyed =

$22.00 - $13.20

= $8.8

To calculate the percentage discount that Priya enjoyed, we divide the discount by the normal price and then multiply the result by 100

= (8.8/22) × 100

= (88/220) × 100

= 0.4 × 100

= 40%

Therefore, Priya enjoyed 40% discount on the price of the pair of earrings.

What is the solution to this system of linear equations 3x 2y 14 5x y 32

Leya [2.2K]

After simplification, the solution of this system of linear equation is (3.85, 12.75).

In the given question we have to find the solution to this system of linear equations 3x-2y=14 or 5x+y=32.

The given system of linear equations is:

3x-2y=14.......................(1)

5x+y=32.......................(2)

Multiply equation 2 by 2, we get

10x+2y=64.......................(3)

Add equation 3 by 1, we get

10x+2y+3x-2y=64-14

13x=50

Divide by 13 on both side, we get

x=3.85

Now put the value of x in equation 2

5(3.85)+y=32

19.25+y=32

Subtract 19.25 on both side, we get

y=12.75

So, the solution of this system of equation is (3.85, 12.75).

Triangle MNP has side lengths 3.5 cm, 4.1 cm, and 4.3 cm. A triangle with what side lengths would be similar to triangle MNP?

atroni [7]

Answer:

Option 1,

The triangle MNP is similar to the triangle with side lengths 35 cm, 41 cm, 43 cm

Step-by-step explanation:

Given triangle MNP has side lengths 3.5 cm, 4.1 cm, and 4.3 cm. we have to find the similarity triangle sides from the given option.

As we know, the two triangles are similar if the measures of the corresponding sides of two triangles are proportional.

For the first option: 35 cm, 41 cm, 43 cm

$\frac{3.5}{4.1}=\frac{4.1}{41}=\frac{4.3}{43}=\frac{1}{10}$

which shows that the sides are proportional.

we have to choose only one option ∴ we needn't have to check the others

Hence, the triangle MNP is similar to the triangle with side lengths 35 cm, 41 cm, 43 cm
