Answer:
![=49.5cm^3](https://tex.z-dn.net/?f=%3D49.5cm%5E3)
so B is the answer ![49\frac{1}{2} cm^3](https://tex.z-dn.net/?f=49%5Cfrac%7B1%7D%7B2%7D%20cm%5E3)
Step-by-step explanation:
![V=whl=2.75*6*3=49.5cm^3](https://tex.z-dn.net/?f=V%3Dwhl%3D2.75%2A6%2A3%3D49.5cm%5E3)
9.286
[To change to mixed number, count the number of digits after the decimal point. There are 3 digits, so the denominator will be 1000]
![9.286 = 9 \frac{286}{1000}](https://tex.z-dn.net/?f=9.286%20%3D%209%20%5Cfrac%7B286%7D%7B1000%7D%20)
Then we simplify the fraction
(286 ÷ 2)/(1000÷2) = 143/500
Therefore,
![9.286 = 9 \frac{286}{1000}](https://tex.z-dn.net/?f=9.286%20%3D%209%20%5Cfrac%7B286%7D%7B1000%7D%20)
1/y = -3x /2 + 3
mulytiply each term by 2y:-
2 = -3xy + 6y
y = 2 / -3( (x - 2)
y = -0.667 (-2 + x)
Answer:
4 + ( -7 X 2 ) = -10
Step-by-step explanation:
Check work:
-7 times 2 is -14.
4 + -14 = -10
X^4=256
x^4-256=0
(x^2)^2-(16)^2=0
(x^2+16)(x^2-16)=0
either x^2+16=0
it gives complex roots.
or x^2-16=0
or x^2-4^2=0
(x+4)(x-4)=0
either x+4=0,x=-4
or x-4=0
x=4
