Thus area of parallelogram is 108 square inches
Answer: 3617.28 cubic millimeters.
Step-by-step explanation: I used the formula of a sphere since a gumball is a shape of a sphere and plugged the radius into the formula.
I got that the volume of a single gumball is 288π cubic millimeters.
Since there are 4 gumballs, i multiplied the volume by 4.
The total volume of the four gumballs add up to be 1152π .
Lastly, I multiplied 1152 by pi
and got the answer to be 3617.28 cubic millimeters
Label each nut with a variable, c = cashews, p = peanuts.....
for a 10-pound mix, you will need c + p = 10
the price for 10-pounds would become 3.29 x 10 = 32.90
You will need an unknown amount of cashews at 5.60/lb and an unknown amount of peanuts at 2.30/lbs to get your full 10 pounds valued at 32.90
5.60c + 2.30p = 32.90
Now you 2 have a system of 2 equations and 2 unknowns
c + p = 105.6c + 2.3p = 32.9utilize substitution to solve:p = 10-c
5.6 c + 2.3 (10-c) = 32.9
solve for c then substitute back into c + p = 10 to solve for P
Hope this helps!
