Answer:
13 2/5
Step-by-step explanation:
a = 2 and b = -3
so the question asks whats.... a^3 - b^3/5
First we plug in the values of a and b
(2)^3 - (-3)^3 /5
Now we solve the ones in paranthesis first
(2)^3 = 8 because 2×2×2 and
-(-3)^3 forget about the - outside the parenthesis so
(-3)^3 = (-27) because (-3)×(-3)×(-3)
now we put it back together
8 -(-27)/5
the two minus become plus so
8 + 27/5
Now we solve it like fractions
8 and 27/5
simplify
13 and 2/5
Hope that helps!
Answer:
see explanation
Step-by-step explanation:
Given the sequence
1, 4, 9, 16, ....
has n th term
= n²
(a)
Given the sequence 2, 5, 10, 17, ......
Note the terms are 1 more than the previous given sequence, thus
= n² + 1
(b)
Given 2, 8, 18, 32, ......
Note the terms are twice the original given sequence, thus
= 2n²
Hello from MrBillDoesMath!
Answer:
Choice B, 24 adults
Discussion:
From the attachment we see that 4 buses are full (they hold 4 * 40 = 160 passengers as each bus can hold 40 people) and the 5th or last bus was 4/5 full. That means the 5th bus had 4/5(40) = 160/5 = 32 passengers. So the total number of passengers on all buses is
(4 * 40) + 32 = 192
Since 1/8 of all passengers are adults, (1/8) 192, or 24, passengers are adults. This is Choice B
Thank you,
MrB
The answer would be about 98 hamburgers.
This is because you would have to divide 393 by 2 to get 196.5.
Since the number of cheeseburgers is doubled divide 196.5 by 2 to get 98.25.
Add 98.25 to 196.5 and get 294.75.
Subtract.
