42 + 5 * 32 - 42 ÷ 23
I am going to use the PEMDAS order. Parenthesis, Exponents, Multiply, Divide, Add, Subtract
Multiply ⇒ 5 * 32 = 160
42 + 160 - 42 ÷ 23
Divide ⇒ - 42 / 23 = -1.83
42 + 160 - 1.83
Add ⇒ 42 + 160 = 202
202 - 1.83
Subtract ⇒ 202 - 1.83 = 200.17
42 + 5 * 32 - 42 ÷ 23 = 200.17

<span>mass of one helium atom x 250 </span>
Express 250 as 2.50.
(6.65 x 10−24)(2.50 x 102)
16.625 x 10<span>−22</span>
1/u = 1/f -1/v
1/v = 1/u + 1/f
Answer:
57.60
Step-by-step explanation:
If the coat is marked up 28%, then the cost is increased by 28% to produce the selling price.
SP = 45 + 28/100 * 45
SP = Selling Price
SP = 45 + 28*45 / 100
SP = 45 + 1260 / 100
SP = 45 + 12.60
SP = 57.60
Answer: The selling price is 57.60
