Step-by-step explanation:
Standard form is a way of writing a small number or a large number easily.
We should give the final answer in standard form.
1) (1.7 × 10⁴) × (8.5 × 10⁻²)
We enter this directly into the calculator to obtain a solution.
= 1445
We write this in standard form we have :
1.445 × 10³
Unit conversion is a way of converting some common units into another. The cost of buying 0.45 pounds of Lily's tea is $144.93.
<h3>What is Units conversion?</h3>
Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimetre is equal to 10 mm, though the real measurement is still the same the units and numerical values have been changed.
As it is given that one gram is equivalent to 0.035273 ounces, while 1 pound is equal to 16 ounces. Therefore, if we convert 0.45 pounds to grams,
Pounds to Ounces
![\rm 1\ pound = 16\ ounces\\\\0.45\ pounds = 0.45 \times 16 = 7.2\ ounces](https://tex.z-dn.net/?f=%5Crm%201%5C%20pound%20%3D%2016%5C%20ounces%5C%5C%5C%5C0.45%5C%20pounds%20%3D%200.45%20%5Ctimes%2016%20%3D%207.2%5C%20ounces)
Grams to Ounces
![\rm 1\ gram = 0.035273\ ounces\\\\1 ounce=\dfrac{1}{0.035273} = 28.35\ grams\\\\7.2\ ounces = 7.20 \times 28.35 = 204.12\ grams](https://tex.z-dn.net/?f=%5Crm%201%5C%20gram%20%3D%200.035273%5C%20ounces%5C%5C%5C%5C1%20ounce%3D%5Cdfrac%7B1%7D%7B0.035273%7D%20%3D%2028.35%5C%20grams%5C%5C%5C%5C7.2%5C%20ounces%20%3D%20%207.20%20%5Ctimes%2028.35%20%3D%20204.12%5C%20grams)
Since it is given that the cost of 1 gram of tea is $0.71, therefore, the cost of 204.12 grams of tea can be written as,
![\rm Total\ cost= 204.12 \times \$0.71 = \$144.93](https://tex.z-dn.net/?f=%5Crm%20Total%5C%20cost%3D%20204.12%20%5Ctimes%20%5C%240.71%20%3D%20%5C%24144.93)
Hence, the cost of buying 0.45 pounds of Lily's tea is $144.93.
