Answer:
V = (2/9)s³
Step-by-step explanation:
The general formula for the volume of a pyramid is:
V = (1/3)(base area)(height).
Here, the length of a side of the square base is s, and so the area is A = s². For the height we use (2/3)s. Then the volume of the pyramid is:
V = (1/3)(s²)(2/3)s, or V = (2/9)s³
Answer:
22%
Step-by-step explanation:
1000-780=220
220/1000=0.22, or 22%
<span>-2x^2-x+7=0
Variable with the highest degree's (exponent) constant, -2 is a, next variable's constant, -1 is b, the constant or number without a variable, 7 is c
using substitution put the numbers into the formula
</span>(-b±√(b^(2)-4ac))/(a^(2))
(-(-1)±√((-1)^(2)-4(-2)(7))/((-2)^(2)) simplify
(1±√(1+56))/4
1±√(57)/4 is your answer
Answer:
I believe Commercial Mathematics is the kind of mathematics for the bussiness world. Where you calculate: There are 12 productions and three companies. Two companies already took 8 productions. How many productions will the last company take? Stuff like that.
Total weight=number of pennies times weight of 1 penny
total weight/weight of 1 penny=number of pennies
636.3/3.03=210
210 pennies
