5. Sally is shopping for diapers and sees a box with 216 diapers for $39.98 and a box with 88
Leya [2.2K]

Answer:

The option with the best deal is 216 diapers for $39.98

Step-by-step explanation:

Sally is shoping for diapers

Sally first sees a box which contains 216 diapers at $39.98

She also sees a second box with 88 diapers for $24.99

To know which option that has the best deal for diapers we have to calculate the amount of 1 diapers in each of the boxes

Box 1

216 diapers= $39.98

1 diaper= x

Cross multiply

216x= $39.98

x= 39.98/216

= 0.19 cents for 1 diapers

Box 2

88 diapers= $24.99

1 diaper= x

Cross multiply

88x= $24.99

x= 24.99/88

= 0.28 cents for 1 diaper

Hence the option with the best deal is 216 diapers for $39.98, this is because it is more cheaper.

Triangle ABC was rotated about the origin. Which rule
Nuetrik [128]
<h3>Answer: Choice A   R_0, 90^{\circ}</h3>

The R stands for "rotation". The "O" as a small subscript means "origin" which is where the x and y axis cross. The 90 degrees means we rotate 90 degrees counterclockwise. This is equivalent to 270 degrees clockwise, but writing R_0, 270^{\circ} is not correct as we don't rotate 270 degrees counterclockwise.

The expression x2y - 2xy - 24y can be factored by first factoring out a common factor of y.
gladu [14]

Answer:

quadratic

Step-by-step explanation:

Given

x²y - 2xy - 24y ← factor out y from each term

= y(x² - 2x - 24) ← quadratic factor

To factor the quadratic

Consider the factors of the constant term ( - 24) which sum to give the coefficient of the x- term (- 2)

The factors are - 6 and + 4, since

- 6 × 4 = - 24 and - 6 + 4 = - 2, hence

x² - 2x - 24 = (x - 6)(x + 4) and

x²y  - 2xy - 24y = y(x - 6)(x + 4) ← in factored form
