Answer:
b=8.5cm
Step-by-step explanation:
tanx (this represents tan theta, it's just easier to type) is equal to 0.6 and since the tanx ratio is opp/adj, we know that opp/adj = 0.6
To find what b is (adjacent as it is adjacent to the angle being used and it is not the hypotenuse), we just have to rearrange.
0.6=5.1/adj
to solve for adj, we can switch 0.6 and adj. (This works because to get adj by itself on one side you would multiply it to the other side and then divide 0.6 from both sides --> simple algebra)
so then you have
adj=5.1/0.6
adj=8.5cm
(if you want to check your solution you can use pythagoeran theorem, a^2+b^2=c^2) and sub everything in and make sure all the numbers equal the right thing!
The answer is 80 because of 16 times 5 that's how you get your answer
hope this helps :)
Answer:
12 =x
Step-by-step explanation:
We can use proportions to solve
6 x
---- = -------
10 10+10
Using cross products
6 ( 10+10) = x*10
6*20 = 10x
120 = 10x
Divide by 10
120/10 = x
12 =x
What are you trying to work out?
If Deshawn’s goal was to raise three-fifths of $1000 you need to fond out what a fifth of 1000 is. You divide 1000 by 5 to get 200. Since it is three fifths you multiply that by 3 which equals $600. Now if Deshawn only reached five-sixths of $600 you need to find out what a sixth of 600 is so divide 600 by 6 which equals 100. Now you multiply that by five as it is 5 sixths of the goal which equals $500. So the answer would be - Deshawn raised $500.
