Answer:
$24
Step-by-step explanation:
For a markup, use the formula <em>a = ( 1 + p ) × w. </em>
!!! Remember, <em>a </em>is the selling price, and <em>w </em>is the original price !!!
!!! The <em>p </em>is the percent in decimal form. 20% as a decimal is 0.20 (move the decimal twice to the left) !!!
<em />
Inserting the values, it should look like <em>a = ( 1 + 0.20 ) × 20 </em>
<em>a = 1.20 × 20 </em>
<em>a = 24</em>
<em />
Hence, the new selling price is $24.
Hope this helps! :)
Answer:
62.8
Step-by-step explanation:
The volume of the cylinder is = base * height
base=Pi*radius*radius, where
base=3.1416*2*2 , height=5
Volume=3.1416*2*2*5
Volume =62.8 cubic units.
Answer: P=313 and C=626
Step-by-step explanation:
939=2x+x
939=3x
313=x Printer is 313 and computer is 626
626+313=939
<span>for the first part, realize that the hour and minute hands are moving at different rates; in one hour, the minute hands moves all the way around the face of the clock, and thus moves a total of 360 degrees or 2 pi radians; the hour hand moves only 1/12 away around the clock, so covers only 30 degrees or Pi/6 radians.
Now, the LINEAR distance traveled by the tip of each hand is also determined by the length of the hand. In the case of the minute hand, it sweeps out a circle of radius 10 cm, so traces out a circle of radius 10 cm. Since the circumference of a circle is 2*pi*r, the minute hand (remember it made one complete cycle) covers a distance of 2*pi*10cm=20 Pi cm
The hour hand covers only 1/12 a circle, but that circle is only 6 cm in radius, so the distance traveled by the tip of the minute hand is:
1/12 *[2 *pi*r]=1/12*[12*pi]=pi
so the difference is 19pi
for the last part, you should draw a diagram of the two hands, the minute hand is 10 cm in length, the hour hand is 6 cm in length, and they are 30 degrees apart...from that drawing, see if you can figure out the remaining leg of the triangle you can form from them
good luck</span><span>
