Answer: 300.3858/ maybe 300.385
Step-by-step explanation: 4 2/7 as decimal= 4.29 x (-18) = -77.22 x -3.89= 300.3858 (3.89 = decimal form of -3 8/9) 300.3858 x 1 = 300.3858
Answer:
3/4
Step-by-step explanation:
28 total but 12 are boys so girls = 28 - 12 = 16
Ratio of boys to girls
= 12/16
= 3/4
The answer would be:
3q x (2q + 1) x (q^2 - 4)
Hope this helped :)
12^2 is 144 and 13^2 is 169. 151 is between those two numbers, so the answer is 12 and 13.
Answer:
25/24
Step-by-step explanation:
sin x = O/H = -7/25
cot x = A/O = -24/7
sec x = H/A
if sin x = -7/25, the opposite side is 7, and the hypotenuse is 25
if cot x = -24/y, the adjacent side is 24 (and the opposite side is still 7)
since H = 25 and A = 24, sec x = 25/24
Also, you know it's positive because when sin x is negative, the angle is in quadrants 3 or 4, and when cot x is negative, the angle is in quandrants 2 or 4, so the only quadrant that satisfies both is 4. In quadrant 4, sec x is positive.
