Answer:
If the hands are at 12 and 3 you would have 1/3
Step-by-step explanation:
At 12 and 3 the hand will take up a third of the clock because at 12 and 3 the clock hands will have a portion of the clock taken up
The fraction of the clock represented when the hands are at 12 and 3 is 1/4.
What is Fraction?A fraction is a mathematical term that represents a part of a whole. It is written in the form of a numerator over a denominator, separated by a horizontal line. The numerator represents the part of the whole that is being considered, while the denominator represents the total number of equal parts that make up the whole.
If the hands of a clock are at 12 and 3, then the hour hand is pointing directly at the 3, while the minute hand is pointing directly at the 12.
The fraction of the clock represented by this configuration is the fraction of the total circumference of the clock that is between the 12 and the 3.
Since there are 12 hour markings on a clock face, each hour marking represents 1/12 of the total circumference. Therefore, the distance between the 12 and the 3 is 3/12 or 1/4 of the total circumference.
So, the fraction of the clock represented when the hands are at 12 and 3 is 1/4.

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]

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

Angle QPU = 110
Step-by-step explanation:
Since angle QPU & RPQ are supplementary angles, they add up to 180 degrees. So take 180 - 70 which gives you 110.
Answer:
Step-by-step explanation:
Note, line UPR is a straight line
Also, angle on a straight line is 180
Therefore,
<QPU and <QPR are supplementary
<QPU+<QPR=180
Given that <QPR=70°
<QPU+70=180
Subtract 70° from both sides of the equation
<QPU=180 -70
<QPU=110
What is the area of the figure?
Enter your answer in the box.
The area of the figure is 112 square inches.
Step-by-step explanation:
Step 1:
To calculate the value of the composite shape we first divide it into shapes that we know.
In this case, the composite shape consists of a triangle and a square attached below it.
If we can calculate the individual areas of the two shapes we should be able to calculate the area of the composite shape.
Step 2:
The triangle has a base length [tex]=10-6=4[/tex] inches and the height is [tex]16-10=6[/tex] inches.
The area of the triangle [tex]= \frac{1}{2} (b)(h) = \frac{1}{2} (4)(6) = 12.[/tex]
The area of the triangle is 12 square inches.
Step 3:
The area of a square is the square of its side length. The given square has a side length of 10 inches.
The area of the square [tex]= a^{2} = 10^{2} = 100.[/tex]
The area of the square is 100 square inches.
Step 4:
Now we calculate the area of the entire figure by adding the areas of the triangle and the square.
Area of the figure [tex]= 100 + 12 = 112.[/tex]
So the area of the figure is 112 square inches.

Step-by-step explanation:
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.
Complete Question:
Given: 2x+3y=6. When x has a value of zero, the y value is 2.
(a) True
(b) False

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]

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 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.
