Answer:
expression for total cost is given by
Step-by-step explanation:
Here we need to find the expression for the total cost
Let us find the cost for x pounds of peanut , y pounds of cashews and z pounds of almonds
cost of 1 pound of peanut = $3.95
cost of x pounds of peanut = $3.95x
cost of 1 pound of cashews = $4.25
cost of y pounds of cashews = $4.25y
cost of 1 pounds of almonds = $5.99
cost of z pounds of almonds = $5.99z
total cost =
cost after 20% off = total cost - 20% of total cost
= 80% of total cost
cost after 20% off =80%
cost after 20% off =
now we can plug x= 2 , y= 3 and z=1
so we have
cost after 20% off = =$ 21.31
Solution-
Capacity of the spherical tank = 800 gallons.
1 gallon = 0.1337 ft³,
Volume of 800 gallons = 800 × 0.1337 = 106.96 ft³
Formula for the volume of sphere
Equating both the volumes
⇒ = 106.96
⇒ = 25.53
⇒
⇒ r = 2.94
∴ Radius of the sphere is 2.94 ft
