This problem is a more like of a percentage increase problem. First, subtract 11 hours by the original hours which is 10 hours. Using mental math, subtracting 11 by 10 would be 1, obviously. Take the outcome of 1 and divide it by the hours he did last week which is 10. 1 divided by 10 would be equal to .1. Convert the decimal to a percentage and then you would get 10% and add it to 100%. So, yes, he is in fact correct.
We would have to have seen the mini lesson because that’s what it’s according too
Answer:
$144
Step-by-step explanation:
divide 272 by 17 and then multiply that answer by 9
272/17 is 16
so 16 dollars an hour
multiply that by 9
you get 144
Answer: 117 degrees
Step-by-step explanation:
Answer:
D) 1/4
Step-by-step explanation:
To solve this, first lets figure out what this variable is. We know we must multiply by t. Well, looking at it, we know that t is one. So lets plug that in.
2*1/2^3(1)
Now we need to figure out what the exponent is that 2 will be raised to. To find that, find out what 3 times one is.
2*1/2^3
Now we need to solve the exponent.
2*1/8
Remember, 2 cubed is eight.
Now we need to find out what 2*1/8 is. To solve this more easily, I am going to turn two into a fraction. This will give us 2/1*1/8. Now we cross multiply, multiplying the numerators by the numerators, and the denominators by the denominators. Remember, the numerator is the top number, and the denominator is the bottom number.
If we do that, we get:
2/8
If we simplify it, we get 1/4. So the asnwer is D) 1/4
