Answer:
Step-by-step explanation:
Given:
- radius = 7 metres
- height = 2 metres
- π = 3.14
To Find:
Solution:
Use the formulae of the volume of cylinder:
where,
- π = 3.14
- r = radius
- h = height
According to the question:
- radius = 7 metres
- height = 2 metres
Substitute the values onto the formulae in order to find out the volume:
<u>Hence,we can conclude that:</u>
The volume of the cylinder is approximately
307.7m³.
.88y +.03y = final cost or more simply .91y = final cost
100% - 12% discount leaves 88% of y (.88y)
3% tax = .03y
.88y + .03y = .91y
Answer:
What are the bases and heights?
It doesnt make sense because i got 104 but thats not one of the options.
Answer:
solve for x in the second equation is correct
Step-by-step explanation:
Here is the complete question
Which first step for solving the given system using substitution results in an equation without fractions?
(2x+6y=7
(6x + 18y = 24.... 2
Solve for x in the first equation,
Solve for y in the first equation,
Solve for x in the second equation
The best equation to she will be equation 2 since all the coefficients are end numbers
Let us make x t subject f the formula from equation 2;
From 2: 6x+18y = 24
Subtract 18y from both sides
6x+18y-18y = 24-18y
6x = 24-18y
Divide through by 6
6x/6 = 24/6 - 18y/6
x = 4-3y.
You can see that the resulting expression of x is not a fraction. Hence solve for x in the second equation is correct
