Answer:
-1
Step-by-step explanation:
I think
Perimeter = 2base + 2base
82 - 2(32) = 18 : 2 = 9
area = 9*32 = 288mm^2
Answer:
Step-by-step explanation:
Composite number
a whole number that has factors other than just 1 and itself
Divisible
able to be divided by a given whole number without a remainder
Factor
a whole number that divides into another number without a remainder
Factor tree
a tree-like structure that uses branches to show the factors of a number
Multiple
the product of a given number and another whole number
Prime factorization
an expression that shows a number expressed as a product of prime numbers
prime number
a whole number that has only two factors, 1 and itself
product
the answer to a multiplication problem
GCF
greatest common factor of a set of numbers
2/3 x + 1 = 27
subtract 1 from each side
2/3 x = 26
multiply by 3/2
3/2 * 2/3 x = 26 * 3/2
x = 39
Answer:
729 in³
Step-by-step explanation:
Fill in the given numbers in the formula and solve for V.
... A = 6V^(2/3) . . . . . . the given formula
... 486 = 6V^(2/3) . . . . with the given area filled in
... 81 = V^(2/3) . . . . . . . divide by 6
... 81^(3/2) = V . . . . . . . raise to the 3/2 power. (2/3)·(3/2) = 1, so we have V on the right
... 729 = V . . . . in³
_____
You may have noticed that (81 in²)^(3/2) becomes 729 in³. The exponent operations work on the units, too.
