Your calculator should give you the answer to both.
3^3 = 3 * 3 * 3 = 27
∛(125) = ∛(5 * 5 * 5) = Three equal factors under a cube root sign give 1 factor on the left of the cube root sign. The other 2 are discarded.
∛(5 * 5 * 5) = 5∛1 = 5
Answer:
yes it is, it's best to look at a graphing calculator for future reference
Step-by-step explanation:
Answer:
45:56.25:78.75
Step-by-step explanation:
a triangle=180º total
4+5+7=16
180÷16=11.25
Answer:
19-(-8)-(-14) = 41
Step-by-step explanation:
First, we have to solve what is in parentheses
by law of signs ( - . - = +)
19 + 8 + 14 = ?
Then, we only have to sum the number to obtain the result
19 + 8 + 14 = 41
Answer:
9) 28% decrease
13) 100% decrease
15) $9.90
17) 272 pages
18) 42 members
19) $27,840
20) 1,863 songs
Step-by-step explanation:
9) Subtract 68 from 95 and you get 27.
Divide 27 by 95 and you get 0.284...
Multiply 0.284... times 100 and you get 28.4.
Round to 28%
13) If a number goes from itself to zero, it's a 100% decrease
15, 18, 20) Divide percent by 100.
Multiply the percent by the initial number.
Add the new number to the initial number
17 and 19) Do everything you did in 15, 18, and 20, but instead of adding the new number to the initial number, subtract it to the initial number
