Step-by-step explanation:
2. To find area, you use this equation: A = l*w
Let's input the values we do know to find the width.
96 = 12 * w
Divide both sides by 12 to isolate the w.
8 = w
The width is 8 cm.
3. We need the find the area of the floor to figure out how many square meters they need. to find area, we multiply the length by the width.
3 * 2 = 6
You need 6 sq. m.
4. To find the circumference, use the equation: C = 2 * pi *r
To find the radius, divide the diameter by 2.
3/2 = 1.5
C = 2pi(1.5)
C = 3pi
The circumference is 3pi. This can also be simplified to 9.42 or 9.4
5. To find the amount of square cm. it covers, multiply the length and width.
40 * 35 = 1,400
The surface covers 1,400 sq. cm.
6. To find circumference, use this equation: C = d * pi
Input the values you do know to find the diameter
15.7 = d * pi
divide both sides by pi to isolate d
4.77 = d
The diameter is approximately 4.8 cm.
7. To find area, multiply length by width. Since we know all sides of a square are the same, you can multiply 15 by 15 to get the answer.
15 * 15 = 225
The area is 225 sq. cm.
8. To find area, use this equation: A = l * w
put the values you know into the equation to find the length.
60 = l * 6
divide both sides by 6 to isolate the l
10 = l
The length is 10 cm.
9. To find the area of a square, the equation is: A = s^2
Input the values you know to find the length of a side.
81 = s^2
Find the square root of both sides to isolate the s.
9 = s
The length of one side is 9 cm.
10. To find the area of a circle, use this equation: A = pi * r^2
Input the values you know and solve for r.
201 = pi * r^2
Find the square root of both sides and divide both sides by pi to isolate the r.
7.998 = r
The radius is approximately 8 cm. Multiply this value by 2 to find the length of the diameter.
8 * 2 = 16
The diameter is approximately 16 cm.
find the product of 3 and 2y-4x=8
Answer:
Step-by-step explanation:
3 * (2y - 4x) = 8
6y - 12x = 8
divide by 2 throughout
3y - 6x = 4
-6x + 3y -4 = 0
To find the product of 3 and the expression 2y - 4x, we multiply both sides of the equation by 3, resulting in 6y - 12x = 24.
The student's question asks us to find the product of 3 and the expression 2y - 4x = 8. Multiplying both sides of the equation by 3 we get:
3 * (2y - 4x) = 3 * 86y - 12x = 24The product of 3 with each term on the left side of the equation has been calculated, resulting in a new equation: 6y - 12x = 24. It is important to carry out the multiplication operation carefully, ensuring that each term within the parentheses is multiplied by 3.

Find the value of x in the figure.
Answer:
x = 27
Step-by-step explanation:
Using the information in the figure, we can conclude that the 3x - 17, x + 40, and 2x - 5 would be the measures of the three interior angles of the triangle. The sum of the interior angles of a triangle is 180° (use the equation: (n-2) × 180°).
By using this information, we can conclude that (3x - 17) + (x + 40) + (2x - 5) would equal 180. We can put this into the equation:
(3x - 17) + (x + 40) + (2x - 5) = 180
To find the value of x in this equation (solve for x), we would have to get the equation into the form x = _.
(3x - 17) + (x + 40) + (2x - 5) = 180
3x - 17 + x + 40 + 2x - 5 = 180
Combine like terms.
6x + 18 = 180
Subtract 18 from both sides to get rid of the +18 on the left side.
6x = 180 - 18
Simplify.
6x = 162
Divide 6 form both sides to get rid of the coefficient of 6 on the left side.
x = 162 ÷ 6
Simplify.
x = 27
x = 27

n a drawer, there are 12 pairs of socks, 6 of which are white. If you randomly select two pairs of socks, what is the probability that both are white? Express your answer as a reduced fraction.
The probability that both pairs of socks selected from a drawer containing 12 pairs, 6 of which are white, are white, is 5 out of 22.
Explanation:The subject of this question is the probability in mathematics, specifically dealing with combinations. In the problem, there are 12 pairs of socks and 6 of them are white. When we are drawing two pairs, we want both to be white which defines our event space.
To find the answer, we need to divide the number of favorable outcomes by the total number of outcomes. The favorable outcome is the probability of choosing 2 white socks out of 6 which can be calculated by combinations (represented by the formula C(n, k) = n! / [k!(n - k)!]). So, C(6, 2) = {6! / [2!(6 - 2)!]} = 15.
The total number of outcomes is the number of ways to pick 2 pairs out of 12, calculated by combinations as well, C(12, 2) = {12! / [2!(12 - 2)!]} = 66.
Now, the probability is favorable outcomes divided by total outcomes = 15/66 = 5/22.

The value of b which satisfies the given quadratic equation is both: A. b = (-3 + 2√3)/2 and (-3 - 2√3)/2.
How to solve a quadratic equation?
In this exercise, you're required to solve for the value of b which satisfies the given quadratic equation. Thus, we would simplify the quadratic equation as follows:
3(2b + 3)² = 36
Dividing both sides by 3, we have:
(2b + 3)² = 12
Taking the square root of both sides, we have:
2b + 3 = ±√12
2b + 3 = ±√4 × √3
2b + 3 = ±2√3
2b = -3 ± 2√3
b = (-3 + 2√3)/2 and (-3 - 2√3)/2.

________+ 1 1/10=3 1/2
Answer: 12/5 or 2 2/5
Step-by-step explanation:
From the question: ________+ 1 1/10=3 1/2
Let the missing value be x
Convert the improper fraction to proper fraction
1 1/10 = 11/10
3 1/2= 7 /2
Therefore, x + 11/10 = 7/2
Subtract both sides of the equation by 11/10 to get the value of x
x + 11/10 - 11/10 = 7/2 - 11/10
x = 24/10
x = 12/5 or 2 2/5
Answer:
2.4 or 2 2/5
Step-by-step explanation:
1. Creating the Equation
This problem is meant to have you work backwards from the information given. In this case, there is no reason to organize information, as this is not a word problem.
Instead, a simpler approach would be to replace the blank space with the variable x.
Once x replaces the blank space, the equation should appear as shown:
x + 1 1/10 = 3 1/2
2. Solving for x
Now that the equation was created, use the order of operations to solve for x.
Firstly, convert all the mixed numbers into improper fractions to simplify the solving process.
x + 11/10 = 7/2
Next, convert the 7/2 fraction into the same denominator as the 11/10 fraction. To do this, multiply both the numerator and the denominator by 5/5.
x + 11/10 = 7/2
x + 11/10 = 5/5(7/2)
x + 11/10 = 35/10
Finally, subtract the 11/10 fraction from both sides of the equation to find the solution to x.
x + 11/10 = 35/10
x + 11/10 - 11/10 = 35/10 - 11/10
x = 24/10
x = 2 4/10
(Simplify the fraction if needed)
x = 2 2/5
As said earlier, x was meant to represent the final answer.
x + 1 1/10 = 3 1/2
x = 2 2/5
2 2/5 + 1 1/10 = 3 1/2

What is the density of a 50-gram pyramid with rectangular base 4 x 8 cm and height 10 cm?
The density of the pyramid is calculated by first finding the volume using the formula for a pyramid's volume, and then dividing the mass by this volume, resulting in a density of approximately 0.469 g/cm³.
Explanation:To find the density of a pyramid with a rectangular base, we first need to calculate its volume. The formula for the volume of a pyramid is V = (1/3)Bh where B is the area of the base and h is the height. In this case, the base has dimensions of 4 cm by 8 cm, so its area is 4 cm * 8 cm = 32 cm². The height of the pyramid is given as 10 cm, so the volume can be calculated as V = (1/3)*32 cm²*10 cm = 106.67 cm³.
With the mass of the pyramid given as 50 grams, the density (ρ) can be calculated using the formula ρ = mass/volume. Thus, the density is 50 grams / 106.67 cm³ = 0.469 g/cm³. Therefore, the density of the pyramid is approximately 0.469 g/cm³.

x + y > 8
x + y ≤ 8
x + y ≥ 8
Answer:

The key idea here is to identify how to translate the statement, no more than, into inequality.
No more than 8 means less or equal to 8.
If Jess saw x dramas and y comedies at the movie theater, and she went to the theater no more than 8 times,then the inequality that best describes the situation is:

If the trapezoid below is reflected across the x-axis, what are the coordinates
of B?
A. (4-8)
B.(-4,-8)
C. (-4,8)
D. ( -8,-4)
As you may have intentionally forgotten to add the diagram. The diagram of the trapezoid is attached below.
Answer:
The point B(4, 8) after reflection across x-axis would be B'(4, -8).
B(4, 8) → B'(4, 8)
Step-by-step explanation:
The rule of reflection across the x-axis states that a reflection of a point, let say M(x, y), across the x-axis does not change the value of x-coordinate but changes the sign of the y-coordinate of the point.
In a nutshell,
The point M(x, y) after reflection across x-axis would be M'(x, -y)
M(x, y) → M'(x, -y)
From the diagram attached below, the coordinate of point B is (4, 8).
So, according to the rule of reflection across the x-axis, the coordinates of the image of the point B (4, 8) after the reflection across the x-axis will be B'(4, -8).
i.e.
The point B(4, 8) after reflection across x-axis would be B'(4, -8).
B(4, 8) → B'(4, 8)
A gray wolf's sperm contains
39 chromosomes. He mates with a female gray wolf.
How many chromosomes will there be in the resulting zygote?
Answer:
The resulting zygote will have 78 chromosomes.
Step-by-step explanation:
The sperm and eggs are the sex cells of animals. These cells contain half the number of chromosomes compared to the number of chromosomes present in the somatic cell of that particular organism.
When the sperm and the egg cell unite to form a zygote, the 39 chromosomes in the wolf's sperm and the 39 chromosomes in the female wolf's egg will add up to male 78 chromosomes in the zygote.
In the process of sexual reproduction in wolves, each parent contributes 39 chromosomes. So, a zygote formed from the sperm of a male wolf and the egg of a female wolf will contain a total of 78 chromosomes.
Explanation:The concept is related to the process of sexual reproduction in mammals, which includes wolves. Since the process of sexual reproduction involves the combination of both parents' genetic material, each parent contributes half the total number of chromosomes in a zygote.
In the case of a gray wolf, the sperm contains 39 chromosomes. Therefore, the egg from the female gray wolf will also contain 39 chromosomes. When the sperm and egg meet during fertilization, they combine to form a zygote containing a total of 78 chromosomes — 39 from the male and 39 from the female.

A segment has a midpoint at (2,-7) and an endpoint at (8,-5). What are the coordinates of the other endpoint?
Answer:
(-4,-9)
Step-by-step explanation:
Given a segment AB with endpoints with coordinates
A: [tex](x_A,y_A)[/tex]
B: [tex](x_B,y_B)[/tex]
The coordinates of the midpoint M of the segment AB are given by:
[tex]x_M = x_A + \frac{x_B-x_A}{2}\\y_M = y_A + \frac{y_B-y_A}{2}[/tex] (1)
In this problem, we know that:
- The midpoint of the segment AB has coordinates
[tex]x_M=2\\y_M=-7[/tex]
- One of the endpoint of the segment has coordinates
[tex]x_B=8\\y_B=-5[/tex]
So we can find the coordinates of the other endpoint A by re-arranging eq.(1) above:
[tex]x_A=2x_M-x_B\\y_A=2y_M-y_B[/tex]
And substituting, we find:
[tex]x_A=2(2)-8=-4\\y_A=2(-7)-(-5)=-9[/tex]
So, the coordinates of the other endpoint are (-4,-9).
To find the coordinates of the other endpoint, use the midpoint formula to average the x-coordinates and the y-coordinates of the given point and the midpoint.
Explanation:To find the coordinates of the other endpoint, we can use the midpoint formula. The midpoint formula states that the midpoint of a line segment is the average of the x-coordinates and the average of the y-coordinates of the endpoints. So, we can calculate the x-coordinate of the other endpoint by averaging the x-coordinates of the given point and the midpoint: (8 + 2) / 2 = 5. Similarly, we can calculate the y-coordinate of the other endpoint by averaging the y-coordinates: (-5 + (-7)) / 2 = -6.
Therefore, the coordinates of the other endpoint are (5, -6).

When a point is reflected over an axis, the coordinate of the other axis changes to its additive inverse.
The coordinates (x,y) when reflected over x axis change to (x,-y)
The polygon is reflected over x axis
then the coordinate ( x,y) will become (x,-y)
After translation, 5 units down, the coordinate change to
