Answer:
The value of given expression is 1.
Step-by-step explanation:
The given expression is

If a is a real number, then
.
![[\because a^0=1]](https://tex.z-dn.net/?f=%5B%5Cbecause%20a%5E0%3D1%5D)
Using exponent property we get,
![[\because a^{-n}=\frac{1}{a^n}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20a%5E%7B-n%7D%3D%5Cfrac%7B1%7D%7Ba%5En%7D%5D)


Therefore the value of given expression is 1.
Answer:
140°
Step-by-step explanation:
The value of supplement is 40 and X. We know that the sum of the sumplementary angles is 180. Therefore ,
=> x + 40° = 180°
=> x = 180° - 40°
=> x = 140°
<h3>
<u>Hence </u><u>the</u><u> </u><u>value </u><u>of </u><u>x </u><u>is </u><u>1</u><u>4</u><u>0</u><u>°</u><u> </u><u>.</u></h3>
Answer:
97.6 cm³
Step-by-step explanation:
Volume of plastic object :
Volume of cylinder - volume of cone
From. The diagram. :
Radius, r = diameter /2 = 4/2
Volume of cylinder = pi*r²h
V = 22/7 * 2² * 8 = 100.53096 cm³
Volume of cone = 1/3*pi*r²h
V = 1/3 * 22/7 * 2² * 8
V = 2.9321531 cm³
(100.53096 - 2.9321531) cm³
= 97.598 cm³
= 97.6 cm³
.666 gallons, you multiply 8/9 by 3/4
and thats how you do it.
