Answer:
312.51 ft
Step-by-step explanation:
You would have to do tangent because if you add a triangle it gives you the opposite side length and you are trying to find the adjacent side lengths to the angle. It would look like this:
tan52=400/x
x*tan52=400*x
xtan52=400
xtan52/tan52=400/tan52
x=400/tan52
x=312.51 ft
Hey there!
Another word for the mean is the average. To find the mean in a set of numbers, you add up the numbers and then divide by the number of numbers!
39+82+74+96+64+52+74=481
Now, we see that we have seven numbers. So, we divide by seven!
481/7≈68.71 (rounded to nearest hundredth)
I hope that this helps!
Answer:
123.75 g
Step-by-step explanation:
You have three unknowns: protein (p), carbohydrate (c), and fat (f)
You need three equations for the three unknowns. They are
(1) p + c + f = 725
(2) 4p + 4c + 9f = 3500
(3) 4p + 9f = 0.45(3500) = 1575
Subtract (3) from (2)
4c = 1925
(4) c = 481.25
Substitute (4) into (1)
p + 481.25 + f = 725
(5) p + f = 243.75
Multiply (5) by 4
(6) 4p + 4f = 975
Subtract (6) from (3)
5f = 600
(7) f = 120
Substitute (7) into (3)
4p + 1080 = 1575
4p = 495
p = 123.75
The diet will include 123.75 g of protein.
