Step-by-step explanation:
This soda can is going to be made from aluminum. How many square centimeters of aluminum are needed if the radius r = 3.5 cm and the height h = 6 cm? (Use π = 3.14 and round answer to the hundredths' place.)
208.81 square centimeters of aluminium are needed
Solution:
Given that,
Radius = 3.5 cm
Height = 6 cm
We have to find the square centimeters of aluminum needed
So we have to find the surface area of cylinder
The surface area of cylinder is given by formula:
[tex]A = 2 \pi r(h+r)[/tex]
Where "r" is the radius and "h" is the height of cylinder
Substituting the values we get,
[tex]A = 2 \times 3.14 \times 3.5 \times (6+3.5)\\\\A = 21.98 \times 9.5\\\\A = 208.81[/tex]
Thus 208.81 square centimeters of aluminium are needed
The soda can requires approximately 208.51 square centimeters of aluminum.
To determine the amount of aluminum needed to make the soda can, we need to calculate the surface area of the cylinder. The formula for the surface area of a cylinder is:
Surface Area = 2πr(h + r)
Given the radius (r) = 3.5 cm and the height (h) = 6 cm, we substitute these values into the formula:
Surface Area = 2 * 3.14 * 3.5 * (6 + 3.5)
First, calculate the term inside the parentheses:
6 + 3.5 = 9.5
Next, multiply by the radius:
3.5 * 9.5 = 33.25
Finally, multiply by 2π:
2 * 3.14 * 33.25 ≈ 208.51
So, the total surface area of the soda can is approximately 208.51 square centimeters of aluminum.
Simplify:
(x-y)/(x+y) - (x+y)/(x-y) =
Final answer:
The simplified form of the expression (x-y)/(x+y) - (x+y)/(x-y) is -4xy / (x²-y²).
Explanation:
To simplify the expression (x-y)/(x+y) - (x+y)/(x-y), we need to find a common denominator and then combine the terms.
The common denominator for the fractions is (x+y)(x-y), which is the product of both denominators and simplifies to x²-y² due to the difference of squares.
Let's go ahead and combine the fractions over this common denominator:
((x-y)² - (x+y)²) / (x²-y²)
Expanding the numerators gives:
(x² - 2xy + y²) - (x² + 2xy - y²) / (x²-y²)
Now, simplify by combining like terms:
(x² - x² - 2xy - 2xy + y² - y²) / (x²-y²)
Cancelling out the x² and y² terms, we are left with:
-4xy / (x²-y²)
Thus, the simplified form of the given expression is:
-4xy / (x²-y²)

A cone has a volume of 33 cubic inches. If
a cylinder has the same height and the same
radius as the cone, what is the volume of the
cylinder?
Answer:
The volume of the cylinder is
[tex]V=99\ in^3[/tex]
Step-by-step explanation:
we know that
The volume of the cone is equal to
[tex]V=\frac{1}{3}\pi r^{2}h[/tex]
[tex]V=33\ in^3[/tex]
so
[tex]33=\frac{1}{3}\pi r^{2}h[/tex]
Multiply by 3 both sides
[tex]99=\pi r^{2}h[/tex] ----> equation A
Remember that
The volume of a cylinder is equal to
[tex]V=\pi r^{2}h[/tex]
The cylinder has the same height and the same radius as the cone
so
Equate the volume of cylinder to equation A
[tex]V=99\ in^3[/tex]
The volume of the cylinder is 99 cubic inches and this can be determined by using the formula of the volume of the cylinder and the volume of the cone.
Given :
A cone has a volume of 33 cubic inches. A cylinder has the same height and the same radius as the cone.The formula of the volume of a cone is given by:
[tex]\rm V = \dfrac{1}{3}\pi r^2h[/tex]
[tex]\rm 3V = \pi r^2h[/tex] --- (1)
The formula of the volume of the cylinder is given by:
[tex]\rm V' = \pi (r')^2 h'[/tex] --- (2)
According to the given data, the cylinder has the same height and the same radius as the cone. That is:
h' = h
r' = r
So, from equations (1) and (2):
V' = 3V
According to the given data, V = 33 cubic inches.
V' = 3(33)
V' = 99 cubic inches
So, the volume of the cylinder is 99 cubic inches.

State your first and last name. Use the letters in your first name and last name to write an equation of a line in slope-intercept form, y=mx + b as follows:
1. Let x = the number of letters in your first name. Write down the coordinates of the x-intercept using this value for x (If your first name is hyphenated, you may use only the first or last part).
2. Let y = the number of letters in your last name. Write down the coordinates of the y-intercept using this value of y (If your last name is hyphenated, you may use only the first or last part).
3. Find the slope of your line using the x and y intercepts from #1 & #2.
Part Two (3 points): Write the equation of the line using y = mx + b. Replace the m with the slope from #3 and the b with the y value from #2. Use the equation generated to complete a table of at least four ordered pairs. You already have two ordered pairs from #1 and #2.
Part Three (5 points): Use graph paper to sketch a graph of the line in part two. Please be sure to write the coordinates of all points on the graph, label the x and y axes, place arrows on your graph.
My name has 6 letters and my last name 9
Answer:
i) b = 9
ii) m = -3/2
iii) another two ordered pairs on the graph can be (2, 6) and (8, -3).
Step-by-step explanation:
i.) equation of the line is y = mx + b
ii) x = number of letters in my first name = 6 is the x-intercept
iii) y = number of letters in my last name = 9 is the y-intercept
iv) if x = 0 then y-intercept is b. then 9 = (0 [tex]\times[/tex] m) + b. Therefore b = 9
v) if y = 0 then x -intercept is given by 0 = (6 [tex]\times[/tex] m) + 9.
Therefore 0 = 6m + 9 [tex]\Rightarrow[/tex] 6m = -9, m = -3/2
vi) another two ordered pairs on the graph can be (2, 6) and (8, -3).
y and z are whole numbers. y<80 and z less than or equal to 70 work out the largest possible value of y+z
Final answer:
The largest possible value for y + z, with y < 80 and z ≤ 70, is 149, achieved by taking the maximum whole numbers within those limits: y = 79 and z = 70.
Explanation:
To find the largest possible value of y + z given that y is a whole number less than 80 and z is a whole number less than or equal to 70, we must choose the largest whole numbers that fit these conditions. For y, the largest whole number less than 80 is 79, and for z, the largest whole number less than or equal to 70 is 70 itself. Therefore, the largest possible value for y + z is 79 + 70.
The calculation is straightforward:
79 (maximum y) + 70 (maximum z) = 149
This is the largest sum of y + z based on the given conditions.

Mother ordered 4 boxes of cupcakes for John's birthday party. As they had more guests than expected, mother ordered 2 more similar boxes of cupcakes. How many cupcakes did each box contain, if there were in total 108 cupcakes for John's birthday party?
Answer:
each box contained 18
Step-by-step explanation:
because 108 divided by the total number of boxes = 18
Final answer:
To determine how many cupcakes were in each of the 6 boxes for John's party with a total of 108 cupcakes, simply divide 108 by 6, resulting in 18 cupcakes per box.
Explanation:
The question asks us to determine how many cupcakes each box contained if there were a total of 108 cupcakes for John's birthday party, and 6 similar boxes were ordered in total. To find the answer, we divide the total number of cupcakes by the total number of boxes.
First, we know that the mother ordered 4 boxes initially and then ordered 2 more boxes, which gives us a total of 4 + 2 = 6 boxes. Then, we are given the total number of cupcakes, which is 108. To find out how many cupcakes each box contained, we divide the total number of cupcakes by the number of boxes:
108 cupcakes ÷ 6 boxes = 18 cupcakes per box
Therefore, each box contained 18 cupcakes.

What is the solution to the system of equations?
Answer:
C.
Step-by-step explanation:
Final answer:
To solve the system of equations x + 14y = 38 and x + 2y = 5, we used the elimination method to find x = -0.5 and y = 2.75.
Explanation:
Solving the System of Equations
The question requires solving a system of linear equations. The given equations are:
x + 14y = 38 (Equation 1)
x + 2y = 5 (Equation 2)
We can solve this system using the substitution method or elimination method. Let's use the elimination method:
Multiply Equation 2 by 7 to make the coefficient of x the same in both equations:
7x + 14y = 35 (Equation 3)
Subtract Equation 3 from Equation 1 to eliminate x:
(x + 14y) - (7x + 14y) = 38 - 35
-6x = 3
x = -0.5
Substitute x = -0.5 in Equation 2 to find y:
-0.5 + 2y = 5
2y = 5.5
y = 2.75
The solution to the system of equations is x = -0.5 and y = 2.75.

William has 24 24 cans of fruit and 60 60 cans of vegetables that he will be putting into bags for a food drive. He wants each bag to have the same number of cans of each type of food. He uses all the cans.how much of each of this bigs will have and how much cans of fruitwill they have and how much cans of vegetables will they have
Answer:
William will make 12 bags of food and each of the bag will contains 2 cans of fruit and 5 cans of vegetables.
Step-by-step explanation:
Given:
Number of fruits cans = 24
Number of veggies cans = 60
William will have to distribute them in equal bags with equal cans of fruits and vegetables respectively.
For this:
We have to find the GCF (greatest common factor) of 24 and 60.
GCF by listing out the factors method.
Factors of 24 : [tex]1,2,3,4,6,8,12,24[/tex]
Factors of 60 : [tex]1,2,3,4,5,6,10,12,15,20,30,60[/tex]
So,
The greatest common factor of [tex]24[/tex] and [tex]60[/tex] is [tex]12[/tex].
The number of bags William will used for equal distribution = [tex]12[/tex]
Now,
We have to distribute the veggies and fruits in equal number of cans to these [tex]12[/tex]bags.
Number of fruits cans used in each bag = [tex]\frac{24}{12} = 2[/tex]
Number of vegetables can used in each bag = [tex]\frac{60}{12} =5[/tex]
We can say that:
William will make 12 bags of food and each of the bag will contains 2 cans of fruit and 5 cans of vegetables.
Final answer:
By computing the greatest common divisor (GCD) of 24 and 60, it is determined that William can create 12 equal bags with each bag having 2 cans of fruit and 5 cans of vegetables.
Explanation:
The student is asking how to divide 24 cans of fruit and 60 cans of vegetables into bags such that each bag contains the same number of cans without any leftovers. This requires finding the greatest common divisor (GCD) of 24 and 60, which is 12. Therefore, William can make 12 bags, with each bag containing 2 cans of fruit and 5 cans of vegetables.
