1.5 mm is what I would think the thickness of the penny would be
<span> (-2.9a + 6.8 ) + (4.4a - 7.37)
=</span> -2.9a + 6.8 + 4.4a - 7.37
= - 2.9a + 4.4a + 6.8 - 7.37
= 1.5a -0.57
Answer: 1.5a - 0.57
Answer:
original price= $150, sale price= $105
Step-by-step explanation:
since it is on sale for 70% of original price, there is 30% off discount.
$45 is 30% of original price (original price is 100%)
1% of original price
= $45 ÷ 30
= $1.50
original price
= $1.50 × 100
=$150
sale price (70% of original price)
= $1.50 × 70
= $105

So, you get the square of the missing side by subtracting 5 squared from 13 squared, which gives 144.
Square root of 144 is the length of the missing side, i.e. 12 cm.
