8) v=1/3 x 6^2 x 11
= 132cm^3
10) 80ft^3
11) 72km^3
Hope this helps!!
Answer:
Step-by-step explanation:
First of all, the number before the decimal would be the whole number of the fraction.
So, 
Then, you would put 0.83 over a fraction.
So because you cannot simplify it anymore, it would be
11. y = -23x - 21
You can get this by starting with y = mx + b (slope intercept form). Then put in all the knowns and solve for the b.
2 = -23(-1) + b
2 = 23 + b
-21 = b
Then add that to the end of the equation with m = -23
12. -5
The y-intercept of an equation is always the number added on at the end of an equation. It is also the number with no x attached to it.
13. 8x^9y^6
When you use the law of exponents, you need to make sure the exponent goes to each individual term. When we cube the 2, it becomes 8. When you cube x^3, you get x^3*x^3*x^3 or x^9. And with y^2 you get y^6
Answer:
144i + 81
Step-by-step explanation:
(-3*9i)(-5 + 3i) + 9i
-27i (-5 + 3i) + 9i
FOIL
135i + 81 + 9i
144i + 81
If you're doing it mentally, you should find a common factor between the nominator and denominator that also multiplies to make 100.
So here,
Divide top and bottom by 6.
That gives you: 3/4
3/4 is 75%
3 x 25 = 75
