Step-by-step explanation:
slope(m)=(Y-Y1)/X-X1
here,
M=1
(X1,Y1)=(11,3)
NOW,
m=(Y-Y1)/(X-X1)
1=(Y-3)/(X-11)
1×(X-11)=Y-3
X-11=Y-3
X-Y-11+3=0
X-Y-8=0
X-Y=0 is the required equation.
The volume of the tank is 1570 cubic meters
<h3>How to determine the volume</h3>
The formula for determining the volume of a cylinder is expressed as;
Volume = πr²h
Where;
- radius is 10 meters
- height is 5 meters
- pi = 3. 14
Now, let's substitute into the formula;
Volume = 3. 14 × 10² × 5
Volume = 3. 14 × 100 × 5
Multiply through
Volume = 1570 cubic meters
Thus, the volume of the tank is 1570 cubic meters

Answer:
The soda costs 2.20 and the sandwich costs 7.70
Step-by-step explanation:
To find this, set the soda cost as x. We now know that the sandwich cost is 3.5x. Add these together and set equal to 9.90
x + 3.5x = 9.90
4.5x = 9.90
x = 2.20
This is the cost of the soda. Now we can multiply that by 3.5 to get the sandwich cost.
3.5 * 2.20 = 7.70
