Answer:
86.9 cm^3
Step-by-step explanation:
You have to find the area of every face. Since the opposite sides have the same area, you can find three areas and then multiply by 2.
2(5.3x2)=21.2
2(4.5x2)=18
2(4.5x5.3)=47.7
You then add the values together...
21.2+18+47.7=86.9

-a=2\times 6−a=2×6
-a=12−a=12
a=-12a=−12
Therefore, the value of a will be -12.

Answer:
Charlie can buy 14 hats at the sale price
Step-by-step explanation:
Let
h ----> the sale price of the hat
x ---> the regular price of the hat
we know that
----> equation A
so
Two hats at the regular price is equal to multiply 2 by x
Multiply by 2 equation A both sides
2 hats at the regular price cost the same that 14 hats at the sale price
therefore
Charlie can buy 14 hats at the sale price
Step-by-step explanation:
| v − 455 | < 23
Writing this without absolute values:
-23 < v − 455 < 23
Solving for v:
432 < v < 478
In interval notation: (432, 478)
This interval is within the range of blue wavelengths, so the fireworks will be blue.
