I just heard Naomi turned down the deal so Nina can't really buy the car no more. Looks like Nina just gotta find some other car or go on foot now :(
Answer:
7+5 first because of pemdas
7+5 = 12
12+4 x 13-2
then 4 x 13
4 times 13 = 52
12+52-2
then add
12+52 = 64
64-2
then subtract
64-2 = 62
Step-by-step explanation:
Pemdas
If there is 30 acres and it was completed in 10 days they completed 3 acres per day. meaning each worker completed 3/24 or 1/8 acres per day. therefore if they have 45 acres and 12 days they need to complete 3.75 acres per day. if each worker completes 1/8 per day then it will take 30 workers to complete the whole site. as it asks for how many extra workers the answer would be 6.
The overall volume is the sum of the volume of a cylinder of height 5'9" and diameter 3'6", and a sphere of diameter 3'6" (two hemispheres = full sphere).
Volume of the cylinder = (area of the base) x (height) = pi * (diameter/2)^2 * 5.75ft = 3.1415 * (3.5ft/2)^2 * 5.75 ft = 55.32 ft^3
Volume of the sphere = 4/3 * pi * (3.5ft)^3 / 8 = 22.45 ft^3
Total volume = (Volume of cylinder) + (Volume of sphere) = (55.32 + 22.45) ft^3 = 77.77 ft^3
