0.9 of 20:
You could also think of 0.9 as 9/10.
9/10, if you multiply by 2/2, is 18/20.
So therefore, you would then know that it would be 18, because 20 was the whole number, so what over 20 is equal to 9/10? 18.
A simpler method is just to multiply. 0.9 * 20 = 18.
Hi there
Total cost of job=
Retail price of goods+labor cost+OH
First find the labor cost
Labor cost=worker A+worker B+worker C
Worker A=13×1.5=19.5
Worker b=9.5×(1+3÷4)=16.63
Worker C=5×(2+3÷4)=13.75
Total labor cost
=19.5+16.63+13.75=49.88
Overhead cost49.88×0.75=37.41
Total cost of job is
74.5+49.88+37.41=161.79
So it's option d
Hope it helps
We have that
(x + 3)² = -20(y − 1)
<span>This is actually the vertex form, so we can obtain the vertex already
</span>the vertex is the point (h,k)------------> (-3,1)
4p=-20------------> p=-5
Focus is at (-3,1-5)---------> (-3,-4)
Directrix is at <span>y = 1-(-5)----------> y=6
</span>
the answer is
the directrix is y=6
see the attached figure
A solid machine part is to be manufactured as shown in the figure. The part is made by cutting a small cone off the top of a larger cone. The small cone has a base radius of 3 inches and a height of 5 inches. The larger cone has a base radius of 9 inches and had a height of 15 inches prior to being cut. What is the volume of the resulting part illustrated in the figure?
