You can make an equation with the information given: Earnings = 6 * r + (1.5*6)o + (6*2) h = 6r + 9o + 12h. Where r is the number of regular hours worked, o is the number of overtime hours and h is the number of holiday hours. Now r = 40, o = 6.5, and h = 8. So, Earnings = 6(40) + 9(6.5) + 12(8) = 39405. <span>Answer: $394.5</span>

I need help finding M and B please
QveST [7]
Hey there!
In our slope-intercept equation, b is the y-intercept, where the line crosses the y-axis. In our case, that happens to be -5, because that's where the line intersects the axis.
Now, we're finding m, or the slope. The slope is defined as rise over run. We can use our slope given two points formula, y2-y1/x2-x1 to find the slope.
For our two points, we'll use the intercept: (0,-5) and the other intercept: (6,0)
Let's plug in our values:
0-(-5)/6-0 =
5/6
Therefore, 5/6 is the slope.
Hope this helps!

Solve - 3 [ ( x + 2 ) ( x - 1 ) - x ^ { 2 } + 1 ] + 3 ( x - 1 ) (and could you please explain it to me?? I really don't get it.
Mazyrski [523]

Answer:

Step-by-step explanation:

(x+2)(x-1)= x^2+2x-x-2= x^2 +x -2\\\\( x + 2 ) ( x - 1 ) - x ^ { 2 } + 1 =x^2+x-2-x^2+1=x-1\\\\- 3 [ ( x + 2 ) ( x - 1 ) - x ^ { 2 } + 1 ] =-3(x-1)=-3x+3\\\\- 3 [ ( x + 2 ) ( x - 1 ) - x ^ { 2 } + 1 ] + 3 ( x - 1 ) =-3x+3+3x-3=6x\\

Tyler has a baseball bat that weighs 28 ounces. Find this weight in kilograms and in grams.
brilliants [131]

Answer

28 ounces = 793.79 grams

28 ounces = 0.79 kilograms.

Step by step explanation

1 ounce = 28.3495 grams

Now let's convert 28 into grams.

Here we have to multiply 28 by 28.3495

28 x 28.3495 = 793.787 grams

Now let's convert 793.787 into kilograms

1 kilograms = 1000 grams

793.787 grams = 0.79 kilograms

myrzilka [38]

Answer:

44.

Step-by-step explanation:

Since the mean of 14, 16, 16, 13, 23, x is 21, then we have 14 + 16 + 16 + 13 + 23 + x is equal to 126. Summing we have 14 + 16 + 16 + 13 + 23 = 82. 82 + x is equal to 126. X = 44.
