Answer:
Ezra will have 5 ounces of water leftover
Step-by-step explanation:
I first divided 4,005 by 16 to get 250.3125, which I rounded to 250. Then I multiplied 250 by 16 to get how many ounces Ezra used, which is 4,000. Then I subtracted that value from how many ounces she had to get how many she had leftover.
I believe the answer to your question is C
a) Due to you have a right triangle, in order to calculate the value of d, use the Pythagorean thorem:
![d=\sqrt[]{(60m)^2+(20m)^2}=\sqrt[]{4000m^2}\approx63.2m](https://tex.z-dn.net/?f=d%3D%5Csqrt%5B%5D%7B%2860m%29%5E2%2B%2820m%29%5E2%7D%3D%5Csqrt%5B%5D%7B4000m%5E2%7D%5Capprox63.2m)
Hence, the distance d is approximately 63.2m
b) To find the angle of elevation, use the sine function of θ, as follow:
![\begin{gathered} \sin \theta=\frac{opposite}{hypotenuse}=\frac{20m}{60m}=\frac{1}{3} \\ \theta=\sin ^{-1}(\frac{1}{3})\approx19.8 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Csin%20%5Ctheta%3D%5Cfrac%7Bopposite%7D%7Bhypotenuse%7D%3D%5Cfrac%7B20m%7D%7B60m%7D%3D%5Cfrac%7B1%7D%7B3%7D%20%5C%5C%20%5Ctheta%3D%5Csin%20%5E%7B-1%7D%28%5Cfrac%7B1%7D%7B3%7D%29%5Capprox19.8%20%5Cend%7Bgathered%7D)
Hence, the angle of elevation is approximately 19.8°
630 acres
Since 1 cow takes
of an acre for grazing that means you can have 3 cattle per acre so simply do 210×3 to get 630
Answer:
x = 124.5
Step-by-step explanation:
adjacent given 88 and asked us to find x, which is a hypotenuse.
using the cosine formula:
![\frac{adjacent}{hypotenuse} = cos(y)](https://tex.z-dn.net/?f=%5Cfrac%7Badjacent%7D%7Bhypotenuse%7D%20%3D%20cos%28y%29)
![\frac{88}{hypotenuse} = cos(45)](https://tex.z-dn.net/?f=%5Cfrac%7B88%7D%7Bhypotenuse%7D%20%3D%20cos%2845%29)
![hypotenuse = \frac{88}{cos(45)}](https://tex.z-dn.net/?f=hypotenuse%20%3D%20%5Cfrac%7B88%7D%7Bcos%2845%29%7D)
![hypotenuse = 124.5](https://tex.z-dn.net/?f=hypotenuse%20%20%3D%20124.5)
