Answer:
30 × 8.8 = 30 × (8 + 0.8) = 240 + 24 = 264
Step-by-step explanation:
I want to buy 30 calculators that cost $ 8.80 each.
So, to calculate the total price, we have to multiply 8.8 with 30.
Now, we have to calculate this multiplication mentally.
To do this, we can write the multiplication as 30(8 + 0.8).
So, we can separately multiply 30 with 8 and calculate it mentally to be 240 and then multiply 30 with 0.8 and calculate it mentally to be 24 and finally add the two products.
Therefore, 30 × 8.8 = 240 + 24 = 264 (Answer)

Answer:
Period =
Amplitude = 4
Step-by-step explanation:
To find the answer, use the form <em>a</em>cos(<em>b</em>x - <em>c</em>) + <em>d:</em>
a = -4
b = 8
c = 0
d = 0
The amplitude is the absolute value of <em>a</em>, so:
|<em>a</em>| = |-4| = 4
To find the period, use this equation:
Replace <em>b</em> with 8 in the formula and solve:
Simplify
So, the period is equal to
