Answer:
Store C, Store B, Store A
Step-by-step explanation:
If you were to buy 1 pound of pears at Store A, It would be $1.29
If you were to buy 1 pound of pears at Store B, It would be $1.00
If you were to buy 1 pound of pears at Store C, It would be $0.89
Step-by-step explanation:
![\cos \theta = \frac{1}{ \sec\theta } = - \frac{3}{ \sqrt{30} } = - \frac{3 \sqrt{30} }{30} = - \frac{ \sqrt{30} }{10}](https://tex.z-dn.net/?f=%20%5Ccos%20%5Ctheta%20%20%3D%20%20%5Cfrac%7B1%7D%7B%20%5Csec%5Ctheta%20%7D%20%20%3D%20%20-%20%20%5Cfrac%7B3%7D%7B%20%5Csqrt%7B30%7D%20%7D%20%20%3D%20%20-%20%20%5Cfrac%7B3%20%5Csqrt%7B30%7D%20%7D%7B30%7D%20%20%20%3D%20%20-%20%20%5Cfrac%7B%20%5Csqrt%7B30%7D%20%7D%7B10%7D%20)
![\cos( \frac{\pi}{2} - \theta )= \cos \frac{\pi}{2} \cos \theta + \sin \frac{\pi}{2} \sin \theta](https://tex.z-dn.net/?f=%20%5Ccos%28%20%5Cfrac%7B%5Cpi%7D%7B2%7D%20-%20%20%5Ctheta%20%29%3D%20%20%5Ccos%20%5Cfrac%7B%5Cpi%7D%7B2%7D%20%20%5Ccos%20%5Ctheta%20%20%2B%20%20%20%5Csin%20%5Cfrac%7B%5Cpi%7D%7B2%7D%20%20%5Csin%20%5Ctheta%20)

Answer:
611 square miles
Step-by-step explanation:
Area of triangle = (1/2)*a*b*sinC (formula when u are not given the height of the triangle, but u are given with the angle.)
= (1/2)*30*47*sin(60°)
= 610.54 square miles (2 d.p)
≈611 square miles (rounded to nearest mile)

Answer:
No
Step-by-step explanation:
Answer:
The answer is 256
.
Step-by-step explanation:
To solve for the volume of the sphere, start by using the sphere volume formula, which is V =
. However, in this formula, 3 will be used instead of (
).
Next, plug in the information given from the problem, and the formula will look like V =
(3) (
).
Then, solve the equation, and the answer will be 256
