0.18 multiple with 8 the answer would be 1.44 0.18x8=1.44
Answer:
$0.21
Step-by-step explanation:
Let x be the amount of money earned per hour before raise and y be amount of money earned per hour after raise.
We have been given that before raise he worked 38 hours and earned $220. We can represent this information as:
We are also told that the next week, he received a raise. After raise he worked 30 hours and made $180. We can represent this information as:
.
Let us solve for x and y.
Therefore, before raise Mike earned $5.7894 per hour.


Therefore, after raise Mike earned $6 per hour.
Now let us subtract 5.7894 from 6 to find Mike's raise.


Therefore, amount of Mike's raise to the nearest cent is $0.21.
Answer:
quadrant 4
Step-by-step explanation:
I find it helpful to remember that the cosine is positive in the right half-plane, and the sine is positive in the top half-plane. Knowing the relationship between sine and cosine and all the other trig functions, you can figure their signs in the various quadrants.
The bottom half-plane (sin < 0) and the right half-plane (cos > 0) overlap in the 4th quadrant.
Answer:
225%
Step-by-step explanation:
You can figure the percentage change from ...
percentage change = ((new value)/(old value) -1) × 100%
= (26/8 -1) × 100% = (3.25 -1) × 100% = 225%
Answer:
Opt. D.
Step-by-step explanation:
To solve this problem we need to focus our attention in the abs(x-1) function,
If x>1, then abs|x-1|= x-1, if x<1 then abs|x-1|= 1-x. And in the two intervals, the function opens upwards.
But our function has -3 multiplying abs|x-1|, This means that our function opens downward.
The vertex point can be found when x=1, since abs(x-1)=0. this gives f(1)=12
