Answer:
$6.42
Step-by-step explanation:
It's very simple, all you have to do is subtract 13.58 by the 20.00$, so you will get that.
So the sum is:
89 + 24 + 17 = 130
Hope it helps :)
Answer:
12.71in
step explanation:
The Length of an arc given is expressed as;
A = theta/360 * 2πr
10 = 45/360 * 2 * 3.14r
10 = 1/8 * 6.28r
Cross multiply
10 * 8 = 6.28r
80 = 6.28r
r = 80/6.28
r = 12.74in
Hence the radius is 12.71in
Answer:
183
Step-by-step explanation:
Evaluate the expression, if x=12, y=8, and z=3 2xy-z3/z
![2xy - \frac{z^3}{z}](https://tex.z-dn.net/?f=2xy%20-%20%5Cfrac%7Bz%5E3%7D%7Bz%7D)
Plug in all the values in the values in the given expression
x=12, y=8, and z=3, Replace all the values
![2xy - \frac{z^3}{z}](https://tex.z-dn.net/?f=2xy%20-%20%5Cfrac%7Bz%5E3%7D%7Bz%7D)
![2(12)(8) - \frac{(3)^3}{3}](https://tex.z-dn.net/?f=2%2812%29%288%29%20-%20%5Cfrac%7B%283%29%5E3%7D%7B3%7D)
![192 - \frac{27}{3}](https://tex.z-dn.net/?f=192%20-%20%5Cfrac%7B27%7D%7B3%7D)
![192 - 9](https://tex.z-dn.net/?f=192%20-%209)
183
First you want to set this into a fraction, so it would be 18/1 because every number has an imaginery one underneath it. then when you divide a fraction you multiply by the reciprical(the opposite) so it would be 18/1 times 3/1 then you can simply cross mutiply and divide, which you can't so then you simply take 18 times 3 which is 108/1 then you divide 108 divided by 1 which is 108, your answer is 108
