Answer:
7 Hours 12 Minutes
Step-by-step explanation:
So they one of the printer increases at a rate of 1/12 and the other increases at a rate of 1/18. Since you don't know the time it actually takes, you will replace both numerators with and x. (x/12 and x/18). You want to set these up so that they are adding. (x/12 + x/18=1). Since you're adding, you want to change it to the same denominator. The lowest is 36 so you multiply x/12 by 3/3 (so you don't unbalance the equation) and x/18 by 2/2. You'll end up with 3x/36 + 2x/36= 1 which will simplify to 5x/36=1. Multiply each side by 36 to leave the variable by itself. It becomes 5x=36 and when you divide it by 5 you get 7.2. So it's seven and .2 hours, which is equivalent to7 and 1/5 of an hour or 7 hours and 12 minutes.
Answer:
It’s the third choice : x ≥8
Step-by-step explanation:
the third choice means he made equal to or greater than $8 an hour.
185-25=160
160÷20=8
Answer:
(a) seems to be the closest to being correct of these five statements.
Step-by-step explanation:
Let's go through the list of possible descriptors:
a) There are no outliers. This seems to be the response most likely to be correct.
b) The distribution is not skewed left. It's skewed right.
c) The center is not 44. From what I see, the center is 48.
d) This distribution is not bimodal; it does not have two peaks.
d) The spread is not 38 to 67; it's 29 to 67.
10/25 = 2/5 Because you divide both sides by 5
