Answer:
Mike made $ 200.63 last Friday.
Step-by-step explanation:
Since Ms. Peralta's friend Mike is a construction worker who gets paid $ 15 an hour, and after working 9 hours he gets paid 1.25 times his hourly rate, and last Friday Mike worked for 5 hours - took an 1 hr and 15 minute break for lunch (does not count toward his work hours) - and worked for an additional 7.5 hours, to determine how much money did Mike make last Friday the following calculation must be performed:
5 + 7.5 = 12.5
12.5 - 9 = 3.5
9 x 15 + (3.5 x (15 x 1.25)) = X
135 + 3.5 x 18.75 = X
135 + 65.625 = X
200.63 = X
Therefore, Mike made $ 200.63 last Friday.
Assuming the time changes at a constant rate, the equation for this is linear (so has the equation y=mx +c)
8am = -2
9am = -0.5
10am = 1.0
11am = 2.5
12pm = 4
<span>m = change in each value </span>or the slope , <span>for this it is m=1.5
</span>c = the y intercept, we find this by: when x=8 y must = 1.5 , which it isn't , y has to = -2 . So c = -3.5
The equation then is: <span>y= 1.5*x - 3.5
</span>
The gradient/slope/m value is 1.5. <span>The answer is 1.5</span>
Answer:
b.
Step-by-step explanation:

The value of x is 21.
To find this one, we need to know the formula with intersecting lines outside of the circle.
It is that if you subtract the smaller arc from the larger arc and divide by 2, you will have the exterior angle.
Therefore, we can write and solve the following equation:
(5x - 63) / 2 =x
5x - 63 = 2x
3x = 63
x = 21
