Answer:
I just learned this about a few weeks ago I hope this helps.
Step-by-step explanation:
Since it's cosine you're only looking at Adjacent and the hypotenuse which the adj is 20 and the hyp is 25 so since cosine is adj/hyp you do 20/25 then simplify it to 20/25 divide both by 5 so it's simplified to 4/5.
Then you do Cos-1(4/5)=36.869 which is rounded to the tenth 36.9 but rounded to the hundredth 36.87.
Hope this helps
Answer:
21.2 yd
Step-by-step explanation:
8 + 6 + 7.2 = 14 + 7.2 = 21.2
a) 9/212 = #mph
b)0.000142045 Miles / 0.000277778 hours = # mph
Step-by-step explanation:
a) 9/212 = #mph
b)
1)9 inches divide the length value by 63360 is 0.000142045 Miles
2) 1 hour 3600 seconds in ones hour so 1/3600 =0.000277778
3) take miles/hour
0.000142045 Miles / 0.000277778 hours = # mph
The signs of the numbers in the problem matter because if a number is negative in the equation than you're answer could be negative. ex. -3/9= -3 but if the negative sign wasn't there than the answer would be wrong bc the answer would be positive.
hope thats what you need hope it helps.
Answer:
C, x ≥ 14.96
Step-by-step explanation:
Step 1: Add 3.408 to both sides.
2.2x − 3.408 (+ 3.408) ≥ 29.504 (+ 3.408)
2.2x ≥ 32.912
Step 2: Divide both sides by 2.2.
2.2x (÷ 2.2) ≥ 32.912 (÷ 2.2)
x = 14.96
