The formula to find the volume of a cylinder is v= hㅠr*2, so you can sub the measurements into the formula.
V = (6)ㅠ(2)*2
V = 6ㅠ4
V= 75.4 (approx)
Answer: x = 0
y = 2
z = -1
Step-by-step explanation:
The system of equations are
x+y+z=1 - - - - - - - - - - 1
-2x+4y+6z=2 - - - - - - - - - 2
-x+3y-5z=11 - - - - - - - - - 3
Step 1
We would eliminate x by adding equation 1 to equation 3. It becomes
4y -4z = 12 - - - - - - - - - 4
Step 2
We would multiply equation 1 by 2. It becomes
2x + 2y + 2z = 2 - - - - - - - - - 5
We would add equation 2 and equation 5. It becomes
6y + 8z = 4 - - - - - - - - - 6
Step 3
We would multiply equation 4 by 6 and equation 6 by 4. It becomes
24y - 24z = 72 - - - - - - - - 7
24y + 32z = 16 - - - - - - - - 8
We would subtract equation 8 from equation 7. It becomes
-56z = 56
z = -56/56 = -1
Substituting z = -1 into 7, it becomes
24y - 24×-1 = 72
24y + 24 = 72
24y = 72 - 24 = 48
y = 48/24 = 2
Substituting y = 2 and z = -1 into equation 1, it becomes
x + 2 - 1 = 1
x = 1 - 1 = 0
Answer:
1.6 kids
2.6
3.6
4.6
5.6
Step-by-step explanation:
if you count by 6 then you will see that im right
Question 1:
We are going to add.
1/5 + 1/2
2/10 + 5/10
7/10
Note that we are going DOWN so the number will be negative.
Therefore, the answer is A.) -7/10
Question 2:
We are going to subtract.
4 1/2 - 1 2/3
9/2 - 5/3
27/6 - 10/6
17/6 or 2 5/6
Note that we are still BELOW sea level so the number will be negative.
Therefore, the answer is C.) -2 5/6
Question 3:
We are going to subtract.
2 2/3 - 1 1/5
8/3 - 6/5
40/15 - 18/15
22/15 or 1 7/15
Therefore, the answer is B.) 1 7/15
Best of Luck!
Answer: 99 and 97
Step-by-step explanation: If you make a numberline and write the numbers 90 through 100. 98 is in between integers 99 and 97.
