A local hamburger shop sold a combined total of 518 hamburgers and cheeseburgers on Tuesday. There were 68 more cheeseburgers sold than hamburgers.
How many hamburgers were sold on Tuesday?
hamburgers
Final answer:
To find the number of hamburgers sold, we set x as the number of hamburgers and x + 68 as the number of cheeseburgers, given that the total sold was 518. The equation x + (x + 68) = 518 is solved to find that 225 hamburgers were sold.
Explanation:
To solve this problem, let's use algebra. Let x be the number of hamburgers, then the number of cheeseburgers would be x + 68 since there were 68 more cheeseburgers sold than hamburgers. Given that the total number of hamburgers and cheeseburgers sold is 518, we can set up the following equation:
x + (x + 68) = 518
Solving for x we get:
2x + 68 = 518
2x = 518 - 68
2x = 450
x = 225
So, the hamburger shop sold 225 hamburgers on Tuesday.

A 1,000 gallon pool (no top) with a rectangular base will be constructed such that the length of the base is twice the width. Find the dimensions (length, width, and height) of the pool that minimize the amount of material needed to construct it.
Answer:
W = 4.646 ft
L = 9.292 ft
H = 3.097 ft
Step-by-step explanation:
Let's say the L is the length, W is the width, and H is the height.
The volume of the pool is:
V = LWH
The area of the pool is:
A = LW + 2LH + 2WH
L = 2W, so substituting:
V = (2W)WH
V = 2W²H
A = (2W)W + 2(2W)H + 2WH
A = 2W² + 4WH + 2WH
A = 2W² + 6WH
Solving for H in the first equation and substituting into the second:
H = V/(2W²)
A = 2W² + 3V/W
Find dA/dW and set to 0.
dA/dW = 4W − 3V/W²
0 = 4W − 3V/W²
4W = 3V/W²
4W³ = 3V
W = ∛(¾V)
V = 1000 gallons or 133.7 ft³.
W = ∛(¾(133.7 ft³))
W = 4.646 ft
So L = 9.292 ft and H = 3.097 ft.

A container is in the shape of a cylinder with a hemisphere on the top. The cylinder has radius 5 cm and height 8 cm. The hemisphere has the same radius as the cylinder.
What is the total surface area of the container? Give your answer in cm2 correct to 3 significant figures.
The total surface area is given by:
The base of the cylinderThe lateral surface of the cylinderThe surface of the hemishpereThe base of the cylinder is a circle with radius 5cm, so its area is
[tex]A=\pi r^2=25\pi[/tex]
The lateral surface of the cylinder is a rectangle whose base is the circumference of the base circle, and whose height is the height of the cylinder. So, its area is
[tex]A=b\cdot h=2\pi r\cdot h = 10\pi\cdot 8=80\pi[/tex]
Finally, the surface of a sphere is given by
[tex]A=4\pi r^2[/tex]
so, half that surface will be
[tex]A=2\pi r^2=50\pi[/tex]
And the total surface area will be the sum of the three areas:
[tex]A=25\pi+80\pi+50\pi = 155\pi[/tex]
Answer:
Total surface area of the figure[tex]=486.7cm^2[/tex]
Step-by-step explanation:
Total surface area of the figure= Surface area of cylinder + Area of the top hemisphere
[tex]r= 5cm\\\\h= 8cm[/tex]
Area of the cylinder with the side walls and the the bottom:
[tex]A=(2*\pi* r*h)+(\pi *r^2)[/tex]
[tex]=(2*3.14*5*8)+(3.14*5*5)\\\\ =251.2+78.5\\\\ = 329.7 cm^2[/tex]
Area of the top hemisphere:
[tex]2*\pi *r^2[/tex]
[tex]=2*3.14*5*5[/tex]
Area of the top hemisphere= [tex]157 cm^2[/tex]
Total surface area of the figure [tex]= 329.7+157\\\\[/tex]

a right rectangular prism is made with 8 small cubes. Each cube has an edge length of 1/5 inch.
What is the volume in cubic inches?
Final answer:
The volume of a right rectangular prism made from 8 small cubes with an edge length of 1/5 inch each is 8/125 cubic inches.
Explanation:
The question asks for the volume of a right rectangular prism made up of 8 small cubes, with each cube having an edge length of 1/5 inch. To find the volume of the right rectangular prism, we must first understand the volume of a single cube, which is found by multiplying the length, width, and height of the cube. Since each side of a cube is equal, the volume of one cube is (1/5 inch) × (1/5 inch) × (1/5 inch), which equals 1/125 cubic inches.
Next, the volume of the entire prism, which consists of 8 such cubes, is calculated by multiplying the volume of one cube by 8. Therefore, the total volume of the prism is (1/125 cubic inches) × 8, which equals 8/125 cubic inches.
The sum of four consecutive even integers is-28
Answer:
-10, -8, -6, -4
Step-by-step explanation:
Perhaps you want to know what they are.
__
The odd number between the middle two is their average value: -28/4 = -7.
The integers are -10, -8, -6, -4.
Answer: The even integers are -10, -8, -6 and -4
Step-by-step explanation:
Let the smallest of the even integers be represented by x, the other three will therefore be x +2, x +4 and x+6
Thus, x + (x+2) + (x+4) + (x+6) = -28
4x + 12= -28
Make x the subject of the equation
4x= -28 - 12
4x= -40
x = -10,
since the x = -10,
x + 2= -10 + 2= -8
x + 4= -10 +4 = -6
x + 6= -10 + 6= -4

Which set of steps will NOT get you to the point (112,4)?
A. Starting at the origin, go 112 units up and then 4 spaces to the right.
B. Starting at the origin, go 4 spaces up and then 112 spaces to the right.
C. Starting at the origin, go 112 spaces to the right and then 4 spaces up.
D. Put one finger halfway between 1 and 2 on the x-axis, and put another finger at the 4 on the y-axis. Move the first finger up and the second finger to the right until they meet.
Option A and D will not get to the required point
Step-by-step explanation:
Step 1 :
a)
Start at origin, go 112 units up and then go 4 unit to the right.
Starting at the origin, 112 units up gives y = 112
then 4 spaces to the right gives x = 4
So the point obtained is (4,112)
Hence option A will not get to the required point
Step 2 :
b)
Starting at the origin, go 4 spaces up and then 112 spaces to the right.
Starting at the origin , 4 spaces up gives y = 4
112 spaces to the right gives x = 112
So we get the point as (112,4)
Option B goes to the required point
Step 3:
c)
Starting at the origin, go 112 spaces to the right and then 4 spaces up.
Starting at the origin, 112 spaces to the right gives x = 112
4 spaces up gives y = 4
We get to the point (112,4)
Hence option C gets to the required point
Step 4:
d)
Doing the procedure in option D gives y = 4, and x as between 1 and 2
Hence this will not get to the required point
Step 5 :
Option A and D will not get to the required point

Which of the following is a solution of x^2 + 5x = -2?
Answer:
x= -0.4385 or -4.5615
Step-by-step explanation:
x²+5x+2=0
Using almighty formula;
a=1, b=5, c=2
x = [ -b± √( b^2 - 4ac)]/2a
x= -5±√(25-8)/2
x=(-5±4.123)/2
Therefore x=(-5+4.123)/2 or (-5-4.123)/2
x= -0.4385 or -4.5615
The solutions are [tex]\(x = \frac{{-5 + \sqrt{17}}}{2}\) and \(x = \frac{{-5 - \sqrt{17}}}{2}\).[/tex]
To find the solution of the equation [tex]\(x^2 + 5x = -2\), we need to solve for \(x\).[/tex]
Let's rearrange the equation to bring all terms to one side:
[tex]\[x^2 + 5x + 2 = 0\][/tex]
Now, we can solve this quadratic equation by factoring, completing the square, or using the quadratic formula. Let's use the quadratic formula:
[tex]\[x = \frac{{-b \pm \sqrt{{b^2 - 4ac}}}}{{2a}}\][/tex]
In our equation, [tex]\(a = 1\), \(b = 5\), and \(c = 2\).[/tex]
[tex]\[x = \frac{{-5 \pm \sqrt{{5^2 - 4(1)(2)}}}}{{2(1)}}\]\[x = \frac{{-5 \pm \sqrt{{25 - 8}}}}{2}\]\[x = \frac{{-5 \pm \sqrt{{17}}}}{2}\][/tex]
So, the solutions are:
[tex]\[x_1 = \frac{{-5 + \sqrt{{17}}}}{2}\]\[x_2 = \frac{{-5 - \sqrt{{17}}}}{2}\][/tex]
Thus, [tex]\(x = \frac{{-5 + \sqrt{{17}}}}{2}\) or \(x = \frac{{-5 - \sqrt{{17}}}}{2}\). These are the solutions to the equation \(x^2 + 5x = -2\).[/tex]

Jordan is cutting a 2 meter by 1 1/4 meter into two pieces by its diagonal line
Question:
Jordan is cutting a 2 meter by [tex]1\frac{1}{4}[/tex] meter piece of rectangular paper into two pieces along its diagonal. what is the area of each of the pieces?
Answer:
Area of each piece of paper is [tex]1 \frac{1}{4} \ m^2[/tex].
Solution:
Length of the paper = 2 m
Width of the paper = [tex]1\frac{1}{4}[/tex] m = [tex]\frac{5}{4}[/tex] m
Area of the rectangle = length × width
[tex]$=2\times \frac{5}{4}[/tex]
[tex]$= \frac{5}{2} \ m^2[/tex]
Diagonal of a rectangle divides it into two equal parts.
Area of each piece = Area of the rectangle ÷ 2
[tex]$=\frac{ \frac{5}{2}}{2}[/tex]
[tex]$=\frac{5}{4} \ m^2[/tex]
[tex]$=1 \frac{1}{4} \ m^2[/tex]
Area of each piece of paper is [tex]1 \frac{1}{4} \ m^2[/tex].

Given: 2x + 3y = 6. When x has a value of zero, the y value is 2.
The statement is true. When x has a value of zero, the y value is 2. So option (a) is correct.
To determine whether the statement is true or false, let's first analyze the given equation:
2x + 3y = 6
We're given that when x = 0, y = 2. We can use this information to solve for y:
2(0) + 3y = 6
0 + 3y = 6
3y = 6
y = 6/3
y = 2
This confirms that when x = 0, y does indeed equal 2. So, the given information is consistent with the equation. Therefore, the statement "When x has a value of zero, the y value is 2" is true.
To summarize:
Given the equation 2x + 3y = 6, when x = 0, y = 2.
Proof:
2(0) + 3(2) = 6
0 + 6 = 6
6 = 6
Thus, when x is 0, y is indeed 2, verifying the statement as true.
