Answer:
4 and a half hours
Step-by-step explanation:
12 times 4 is 48 and to get to 54 he worked for another half hour which got him 6 dollars
For each ounce of the product, let
x = ounces of moisturizing lotion used,
y = ounces of self-tanning lotion used.
The sum of the two lotions per ounce is equal to one ounce. Therefore
x + y = 1 (1)
Moisturizing lotion costs $0.70 per ounce.
Self-tanning lotion costs $22 per ounce.
Because the product costs $1.30 per ounce. Therefore
0.70x + 22y = 1.30 (2)
From (1), obtain
y = 1 - x (3)
Substitute (3) into (2).
0.70x + 22(1 - x) = 1.30
0.70x - 22x + 22 = 1.30
-21.3x = -20.7
x = 0.9718 ounces
From (3), obtain
y = 1 - 0.9718 = 0.0282 ounces.
A batch of the product is 700 ounces. Therefore the amount of self-tanning lotion used is
700*y = 700*0.0282 = 19.74 ounces
Answer: 19.74 ounces
It would be D: 181
3 17
---- = ------
32 X
Then you would cross multiply and divide.
I'll try to help you round these numbers
37 rounded to Tens will be 40
because 7 is bigger than 3 so the 7 will change the 3 to a 4 and the 7 will be a 0.
29 rounded to Tens will be 30
because the 9 is bigger than 2 so it will change the 2 to a 3 and the 9 will be a 0. Just like 37 rounded into a 40.
669 rounded to Hundreds will be 700
Its 700 because the 9 is bigger and it will change the 6 beside it to a 10 which means that the 9 will be a 0. The 6 that turned to a 10 will turned will be a 0 because your carry the 1 to the other 6 which would turn to a 7 and the two numbers behind 7 will be 0's which makes that be 700.
9,492 rounded to Thousands will be 9,000
Ok this is 9,000 because the 4 is smaller than 9 which the 9 will become the bigger person and turn all the little numbers thats behind it to 0's and even that 9 between the 4 and the 2. So thats why its 9,000.
Hope this helps!
