Answer:
126
Step-by-step explanation:
First multiply 6 by 1. This equals 6. Then, multiply 6 by 20 to get 120. 6+120=126.
It depends on which number has the greatest absolute value.
Think about it as money
If you owe me $10, this is shown as -10
Now if I give you back 2 dollars (+2), How much money do I still owe you.
The equation is -10+2
I still owe you 8 dollars which is portrayed as -8
Hope this helps :)
Step-by-step explanation:
x=14-6y/3
substituting x=14-6y/3 into eqn 2
2(14-6y/3)+8y=2
multiplying through by 3
2(14-6y/3)×3 +8y×3=2×3
2(14-6y)+24y=6
28-12y+24y=6
28-12y=6
28-6=12y
22=12y
22/12=y
finding x
2x+8(22/12)=2
2x+44/3=2
2x=2-44/3
x=(-38/3)/2
×=-38/6
The formula for the volume of a cone, V, is:
V = [1/3] * π * (radius)^2 * height
Here radius = 6 feet / 2 = 3 feet
Height = 15 feet
V = [1/3] π (3 feet)^2 * 15 feet = 45π feet^3
Answer: 45π feet^3
