Which set of numbers could represent the side lengths of a right triangle?
sveticcg [70]

Answer:  D) 8, 15, 17

<u>Step-by-step explanation:</u>

In order for three side lengths to represent a right triangle, they must satisfy the Pythagorean Theorem: a² + b² = c²    where c is the largest side.

A) 2² + 3² = 4²

   4  +  9   = 16      

       13      = 16      FALSE

B) 4² + 5² = 6²

  16  + 25 = 36

       41     = 36       FALSE

C) 6² + 9² = 12²

   36 + 81 = 144

       117    = 144       FALSE

D) 8² + 15² = 17²

  64 + 225 = 289

       289    = 289     TRUE!

Please help and Thank you whoever you are.
LiRa [457]

Answer:

Whole #'s: All natural numbers plus 0

Integers: Whole numbers and their opposites

Rationals: Can be expressed as ratios, repeating numbers, decimals, so on.

1.

-2/5 is a fraction or ratio, meaning it doesn't belong in whole NOR integer.

-2/5 belongs in the rationals box.

-7.8 is negative, but it is a decimal, so it belongs in the rationals box.

1/10 is not a whole, not an integer, but a rational number.

13 is a whole number, integer, and rational, so it belongs in the whole box.

10 is also a whole number grouped under the categories given.

-5 is the opposite of 5, and whole numbers aren't negative, so -5 belongs in the integers box.

-8/4 is a fraction, not considering its simplified form that would give -2, so it belongs in the rationals box.

2.

We know there are 208 pages in total. On Monday, she read 3/8 of the pages. This can be demonstrated as 208 * 3/8, which is 78. 208-78 = 130.

We know there are 130 pages left. On Tuesday, she reads 28 pages. 130-28=102

We know there are 102 pages left. On Wednesday, she read 1/4 of the total pages. 1/4 (of) 208 is 1/4*208, that is 52.

To know how many pages are left, we subtract her read pages from the remaining pages. 102-52 = 50.

Amanda has 50 pages left until she finishes the novel.

Hope this helped.

Line p has an equation of y=-8x+6. Line q, which is perpendicular to line p, includes the point (2,–2). What is the equation of
Arturiano [62]

Answer:

y =  \frac{1}{8} x - 2  \frac{1}{4}

Step-by-step explanation:

<u>Slope-intercept </u><u>form</u>

y= mx +c, where m is the slope and c is the y-intercept

Line p: y= -8x +6

slope= -8

The product of the slopes of perpendicular lines is -1. Let the slope of line q be m.

m(-8)= -1

m= -1 ÷(-8)

m= ⅛

Substitute m= ⅛ into the equation:

y= ⅛x +c

To find the value of c, substitute a pair of coordinates that the line passes through into the equation.

When x= 2, y= -2,

-2= ⅛(2) +c

- 2 =  \frac{1}{4}  + c

c =  - 2 -  \frac{1}{4}

c =  - 2 \frac{1}{4}

Thus, the equation of line q is y =  \frac{1}{8} x - 2 \frac{1}{4}.
