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!
Answer:
The actual formula for the circumference is 2rpi. But the radius multiplied by 2 is the diameter. They are both right. Plug it the values in the formul and you will see. Sry if it doesn't make sense

Answer:
![2w - \frac{ 7}{4}](https://tex.z-dn.net/?f=2w%20-%20%20%5Cfrac%7B%207%7D%7B4%7D%20)
Step-by-step explanation:
![\frac{1}{4} \times 8w = 2w \\ \frac{1}{4} \times ( - 7) = \frac{ - 7}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B4%7D%20%20%5Ctimes%208w%20%3D%202w%20%5C%5C%20%20%5Cfrac%7B1%7D%7B4%7D%20%20%5Ctimes%20%28%20-%207%29%20%3D%20%20%5Cfrac%7B%20-%207%7D%7B4%7D%20)
Answer:
Step-by-step explanation:
Stephan can run
3 miles in 15.75 minutes
1 miles in 15.75/3 minutes
1 miles in 5.25 minutes
Kelsha can run
5 miles in 226 minutes
1 miles in 226/5 minutes
1 miles in 45.2 minutes
Stephan can run faster, since 5.25 < 45.2
