1 answer:

7 0

All you need to do to answer this question is multiply 2 (the dropping temperature) by 7 (time in hours) which is 14. Subtract 14 from 12 and your answer is -2 degrees Fahrenheit

Simplify the radical expression completely LaTeX: 3\sqrt{5}\:-\:3\sqrt{11}+2\sqrt{121}-3\sqrt{90}3 5 − 3 11 + 2 121 − 3 90 A. La

Answer:

$3\sqrt{5}\:-\:3\sqrt{11}+22-9\sqrt{10}$

Step-by-step explanation:

Given

$3\sqrt{5}\:-\:3\sqrt{11}+2\sqrt{121}-3\sqrt{90}$

Required

Simplify the expression

$3\sqrt{5}\:-\:3\sqrt{11}+2\sqrt{121}-3\sqrt{90}$

Express the square root of 121 as 11

$3\sqrt{5}\:-\:3\sqrt{11}+2 * 11-3\sqrt{90}$

$3\sqrt{5}\:-\:3\sqrt{11}+22-3\sqrt{90}$

Express 90 as 9 * 10

$3\sqrt{5}\:-\:3\sqrt{11}+22-3\sqrt{9 * 10}$

Split the surd to 2

$3\sqrt{5}\:-\:3\sqrt{11}+22-3\sqrt{9} * \sqrt10}$

Express the square root of 9 as 3

$3\sqrt{5}\:-\:3\sqrt{11}+22-3 * 3 * \sqrt10}$

$3\sqrt{5}\:-\:3\sqrt{11}+22-9 * \sqrt10}$

$3\sqrt{5}\:-\:3\sqrt{11}+22-9\sqrt{10}$

Hence, the result of the expression is

$3\sqrt{5}\:-\:3\sqrt{11}+22-9\sqrt{10}$

Which ratios are less than 8 to 10? Check all that apply. 6/20 3:5 50/100 13:15

poizon [28]

Answer:

6/20, 3:5, 50/100 are all less than 8/10

Step-by-step explanation:

It can help to give all the ratios a common denominator. (We'll use 100, and fudge the last one a bit.)

8/10 = 80/100 . . . . our reference value

6/20 = 30/100 . . . less than 8/10

3/5 = 60/100 . . . . less than 8/10

50/100 . . . . . . . . . less than 8/10

13/15 ≈ 86.7/100 . . . more than 8/10
