Answer:
a
Step-by-step explanation:
There are 42 people and 7 pizzas. That means 7 pizzas will be split for 42 people. 7 ÷ 42 = x
<h3>
Answer: angle B = 47 degrees</h3>
========================================
Work Shown:
Use law of cosines to find angle B
b^2 = a^2 + c^2 - 2*a*c*cos(B)
9^2 = 6^2 + 12^2 - 2*6*12*cos(B)
81 = 36 + 144 - 144*cos(B)
81 = 180 - 144*cos(B)
81 - 180 = -144*cos(B)
-99 = -144*cos(B)
-144*cos(B) = -99
cos(B) = (-99)/(-144)
cos(B) = 0.6875
B = arccos(0.6875)
B = 46.5674634422102
B = 47 when rounding to the nearest whole number
Make sure your calculator is in degree mode.
arccos is the same as inverse cosine often labeled on calculators.
I’m selfish, impatient and a little insecure. I make mistakes, I am out of control and at times hard to handle. But if you can’t handle me at my worst, then you sure as hell don’t deserve me at my best. ― Marilyn Monroe
Answer: 16
Step-by-step explanation:
Guests = x
5x/8 = 10
x = 16
This one is . . . (13 lbs)/(5/8 lbs / bag) = 13*8/5 = 104/5 = 20 4/5
