Answer:
$0.407291667 per ounce
Step-by-step explanation: there are 16 ounces in a pound. 16 times 3 is 48.
in order to find the price per ounce, we need to divide the total price by the number of ounces
19.55/48 is 0.407291667
First, 90 minutes will equal 1.5 hours. And I have the formula for this is distance=time×speed, so I just take 25 divided 1.5 to get the speed she is riding which equal 16 2/3 miles per hour. Hope it help!
Answer:
8a(5a - 4)
Step-by-step explanation:
To factor this expression, see what numbers and variables these two terms have in common. I can see that they both have the variable a, so a can be factored out.
40 and -32 also have 8 in common, because they are both cleanly divisible by 8.
Now we can factor 8a out of 40a^2 - 32a. Think of how many times 8a goes into 40a^2 and -32a.
8a(5a - 4)
