Answer:
Step-by-step explanation:
<u>Volume of the pyramid:</u>
<u>Find base area:</u>
- B = 1/2(20 + 30)*20 = 500 cm²
<u>Substitute value of the volume and find the height of the pyramid:</u>
- 4500 = 1/3*500*h
- h = 4500*3/500
- h = 27 cm
<u>The boxes with h > 27 can fit the pyramid: </u>
Hi there! The answer is 8y + 48.
First work out the parenthesis.
Rewrite the expression in order to collect the terms.
Next up, collect the terms.
Now we've found our answer.
The price after tax is £253.87 so to find the original price you have to deduct 6% but first you need to find 6%.
Easiest way to find 6% is by finding 10% or 2% or 1% / whatever you find easiest. For me it would be 1%
If you find 1 % you would then multiple it by 6 to give you 6%
10% is £25.38 (move the decimals 1 unit)
1% is £2.54 (move decimals 2 units)
Always round up
£2.54 X 6 = £15.24
£253.87 - £15.24 = £238.63
