Answer:

a straight line passing through 0,0

Jan spent the day at the mall. She came home with $9.50. She spent $5.25 on earrings and 3 times that amount on a shirt. How muc

ki77a [65]

Answer:

She took $30.50 to the mall originally

Step-by-step explanation:

Let us solve the problem step by step

∵ She spent $5.25 on earrings

∵ The price of the shirt is 3 times the price of the earrings

∴ The price of the shirt = 3 × 5.25 = 15.75

∴ She spent $15.75 on the shirt

Find her total spending in the mall by adding the prices of earrings and the shirt

∴ She spent = 5.25 + 15.75 = 21

∴ She spent $21 on the mall

∵ She came home with $9.50

∵ She spent $21 on the mall

- Add them to find her original amount of money

∴ She took = 21 + 9.50 = 30.50

∴ She took $30.50 to the mall originally

Is QRS a right triangle? Why or why not?

Yuliya22 [10]

Answer:

Step-by-step explanation:

Using Pythagoras' identity to determine if the triangle is right

The square of the longest side should equal the sum of the squares on the other 2 sides, that is

QS² = RS² + QR² = 8² + 5² = 64 + 25 = 89 ( take the square root of both sides )

QS = $\sqrt{89}$

Δ QRS is not right as QS would have to be $\sqrt{89}$

If the length of a rectangle is 120 m and the diagonal measures 130 m what is the perimeter and area of the rectangle

Leviafan [203]

Answer:

Step-by-step explanation:

width=√(130²-120²)=√[10²(13²-12²)]=10√(13+12)(13-12)=10√(1×25)=10×5=50 m

perimeter=2(120+50)=2×170=340 m

area=120×50=6000 m²
