Answer: C

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

Varies inversely means xy = k

A. 1(-3) = -3

2(-9) = -18

-3 ≠ -18

B. 1(-6) = -6

2(-12) = -24

-6 ≠ -24

C. 1(6) = 6

2(3) = 6

3(2) = 6

6 = 6 = 6 This works!

D. 1(-3) = -3

2(2) = 4

-3 ≠ 4

The only table that has the same k-value is option C.

Write yes if the given set of lengths are side lengths of a right triangle. Otherwise write No

Amiraneli [1.4K]

Answer:

a) Yes

b) No

c) Yes

d) No

e) No

Step-by-step explanation:

Right triangle:

The square of the larger side is equals to the sum of the squares of the smaller sides.

a. 6, 8, 10

$6^2 + 8^2 = 36 + 64 = 100 = 10^2$

The answer is yes.

b. 8, 15, 16

$8^2 + 15^2 = 64 + 225 = 289 \neq 16^2 = 256$

So no.

c. 10, 24, 26

$10^2 + 24^2 = 100 + 576 = 676 = 26^2$

So yes

d. 20, 21, 28

$20^2 + 21^2 = 400 + 441 = 841 \neq 28^2 = 784$

So no.

e. 9, 35, 41

$9^2 + 35^2 = 81 + 1225 = 1306 \neq 41^2 = 1681$

A pair of ordinary dice is rolled. What is the probability that each die will show a number higher than 4. 1. (1/36) 2. (1/12) 3

mihalych1998 [28]

Answer:

the answer is 1/12

Step-by-step explanation:

it is 1/12 because if there are only a pair you would have 2 dice. and since each die has numbers all the way up to 6 all you have to do is add them. and don't count all the numbers. like add 1+2+3+4+5+6. that's just plain wrong just do add the highest number on each die (6+6)

How to find variables x- and y-

Monica [59]

It says that the triangles are congruent (same size). Also, a triangle's angles add up to 180 degrees. In both of these triangles, one angle is 90° and another angle is 52°. The other angle is 180°-90°-52°=38°.

Solve these equations to find x and y: 2x+18=38, 3y+11=38

$2x+18=38\\2x=20\\x=10$

$3y+11=38\\3y=27\\y=9$
