Answer: 4.5 feet he can buy if he has $11.25
Step-by-step explanation:
Since we have given that
Cost of candy per foot = $2.50
Total money he spent on candy = $11.25
Let the number of feet he can bought be x
Now, According to question, we get that ,
So, 4.5 feet he can buy if he has $11.25.
Solve for h
h = [S / (2πr)] - r
It is a case about two-variable linear equations and we have to solve the equation to get the variable h.
Our main plan is to isolate the variable h alone at the end of the process on one side of the equation until the variable will be equal to the value on the opposite side.
We can set it to be like this, i.e., just swapping positions on both sides but not changing the signs.
We subtract both sides with .
We divide both sides with
We get the results as follows:
- - - - - - -
Let's check again from the beginning.
For example, r = 2 and h = 3, then we first calculate the value of S by using the initial equation.
Then, we substitute the results of S (with r = 2) into the new equation that we have compiled with h as the subject.
We get the value h = 3 and it means that the equation has been proven.
Notes:
The formula that we discussed above is a formula for calculating the surface area of a closed cylinder.
Keywords: S=2πr^2+2πrh, solve for h, subtract, divide, subject, to isolate the variable h alone, two-variable linear equations
To solve for 'h' in the equation S = 2πr^2 + 2πrh, subtract 2πr^2 from both sides, divide by 2πr, simplifying the right side of the equation.
To solve for h in the equation S = 2πr^2 + 2πrh:

Answer:
7.6 ft² ( to 1 dec. place )
Step-by-step explanation:
given 2 sides of a triangle and the angle between them, the area (A) is calculated using the formula
A = ac sin B
= 0.5 × 4 × 13 × sin 17° ≈ 7.6
The dinner check was $85.00. If Tyler gave the waiter a 20% tip, how much did Tyler spend in total?
Answer:
It is $17.
Step-by-step explanation:
Intercept of equation 2x + 3y - 6z = 30 is (15, 0, 0) , (0, 10, 0) and (0, 0, -5)
Given equation is:
2x + 3y - 6z = 30
We have to find the intercepts
Intercept are the point where equations cut the x- axis, y- axis and z- axis.
Thus, at x- axis:
y and z both are zero
So substitute y = 0 and z = 0 in given equation
2x + 3(0) - 6(0) = 30
2x = 30
x = 15
Thus at y - axis:
x and z both are zero
So substitute x = 0 and z = 0 in given equation
2(0) + 3y -6(0) = 30
0 + 3y + 0 = 30
3y = 30
y = 10
Thus at z - axis:
x and y are both zero
So substitute x = 0 and y = 0 in given equation
2(0) + 3(0) - 6z = 30
-6z = 30
z = -5
Thus, intercept of equation 2x + 3y - 6z = 30 is (15,0,0) ,(0,10,0) and (0,0,-5)
