Hello! So Angie reads 60 pages in 2 hours, without the TV on. 60/2 is 30. She reads 30 pages an hour without the TV on, and 24 pages with the TV off. To find the percent of her reading rate with the TV on instead of off, we can just divide both of the reading rates. 24/30 is 0.8. Multiply that by 100 and you get 80% in percent form. There. Angie's reading rate with the TV on is 80% of her reading rate with the TV off. The answer is B: 80%.

EXTRA POINTS! FIND THE MISSING DIMENSION! NEED ASAP
yanalaym [24]

Answer:

x = 10.5 in

Step-by-step explanation:

The rectangles are similar, thus the ratios of corresponding sides are equal.

that is \frac{7}{2} = \frac{x}{3} ( cross- multiply )

2x = 21 ( divide both sides by 2 )

x = 10.5

You can put this solution on YOUR website!

we are given the following

x^2 +(x+1)^2 = 685

x^2 +x^2+2x+1 = 685

2x^2 +2x = 684

x^2 +x = 342 and

x^2 +x -342 = 0

use quadratic equation to solve for x

x = (-1 + or - square root(1 - 4*1*(-342)) / 2

x = (-1 + or - 37) / 2

the problem does not state if our consecutive integers are positive or negative

x = 18 or -19

18^2 + 19^2 = 685

324 + 361 = 685

685 = 685

now

-19^2 + -18^2 = 685

361 + 325 = 685

so our integers are 18, 19, -19, -18

The sum of the squares of two consecutive integers is 685. Find the integers.

--------

1st: x

2nd: x+1

Equation:

x^2 + (x+1)^2 = 685

x^2 + x^2 + 2x + 1 = 685
