Answer:
107.86 to 2 d.p.
Step-by-step explanation:
makes a triangle. 120 feet is the hypotenuse.
we want to find the opposite so we will use sine.
sin(x) = opp/hyp which means opp = sin(x)hyp.
opp = sin(64)120
opp = 107.86 to 2d.p.
The answer is (6x+1)•(x+4)•(x+3)
30 percent decrease
Step-by-step explanation:
looking at this i know its a percent decrease
so how do we find percent decrease ?
first we subtract the first value 39.39 & the final value 27.57
39.39-27.57 = 11.82
then we divide 11.82 by the first value
like this 11.82÷39.39 = 0.3000
then we multiply what we got by 100
0.3000×100= 30 percent
the way that most people mess up is when they divide sometimes they might do 39.39 divided by 11.82 instead of 11.82÷39.39.
Answer:
25 pages
Step-by-step explanation:
We know that Zakarya can read 5 pages in 8 minutes. First we divided 40 by 8, to see how many times of 8 she reads. She reads for 8 five times (40 minutes). We can multiply 5 (number of 8 minutes she reads) times 5 (pages she reads every 8 minutes) to get 25. She reads 25 pages in 40 minutes. Please tell me if this is wrong or makes no sense :).
