Which could be the cross section of a square pyramid? Select all that
apply.
Choose all that apply:
trapezoid
triangle
circle
pentagon
square
Final answer:
Cross sections of a square pyramid can include a trapezoid, a triangle, or a square. A circle or a pentagon are not possible shapes for these cross sections because they don't align with the pyramid's geometric structure.
Explanation:
The cross section of a square pyramid could be either a trapezoid, a triangle, or a square, depending on the plane's angle relative to the pyramid's base and sides. A circle or a pentagon cannot be cross sections of a square pyramid since they do not conform to the sides or base of a square pyramid.
A trapezoid cross-section can be obtained if the cutting plane is parallel to one base edge and intersects the other three edges of the pyramid. A triangle appears when the cutting plane passes through one vertex and cuts through the base, creating a cross section congruent to the faces of the pyramid. Lastly, a square section results when the cutting plane is parallel to the base and slices through the pyramid.

What is slope?In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).
here, we have,
In order to find the best equation to descibe the housing price, we have to calculate the slope of the line first.
The equation of the line can be written as
y = mx + q
where m is the slope and q the y-intercept.
In order to have the most accurate estimate for the slope, we use the first point and the last point, that are:
(1900, 196)
and
(2200, 225)
The slope of the line is calculated as:
m = y2-y1/x2-x2 = 0.097
So, the slope of the line is 0.097.
Therefore, the correct option is the only one having a slope of 0.097, which is:
B. y = 0.097x + 11.142

Answer: The height is 12 inches.
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume: area x height
Replacing with the values given:
972 cubic inches = 81 square inches x h
Solving for h (height)
972/81 = h
12 inches =h
The height is 12 inches.

530 : 34 =?
Write your answer as a whole number and remainder.
To divide 530 by 34, divide the quotient and the remainder. The whole number part of the quotient is 14 and the remainder is 54.
Explanation:To divide 530 by 34, we start by determining how many times 34 can fit into 530. We find that 34 can fit into 530 fourteen times. So, the whole number in the answer is 14. Now we calculate the remainder by subtracting 14 times 34 from 530. The remainder is 530 - (14 * 34) = 530 - 476 = 54.
Therefore, the answer to 530 divided by 34 is 14 with a remainder of 54.

What is the surface area of this cylinder?
Use a ~ 3.14 and round your answer to the nearest hundredth.
The surface area of the cylinder is [tex]\( 904.32 \, \text{cm}^2 \)[/tex]
The surface area (A) of a cylinder is given by the formula:
[tex]\[ A = 2\pi r^2 + 2\pi rh \][/tex]
where:
- [tex]\( r \)[/tex] is the radius of the base,
- [tex]\( h \)[/tex] is the height,
- [tex]\( \pi \)[/tex] is a constant approximately equal to 3.14.
Given the values:
- Radius [tex](\( r \))[/tex] = 8 cm
- Height [tex](\( h \))[/tex] = 10 cm
- [tex]\( \pi \)[/tex] = 3.14
Plug these values into the formula:
[tex]\[ A = 2 \times 3.14 \times (8)^2 + 2 \times 3.14 \times 8 \times 10 \][/tex]
[tex]\[ A = 2 \times 3.14 \times 64 + 2 \times 3.14 \times 80 \][/tex]
[tex]\[ A = 401.92 + 502.4 \][/tex]
[tex]\[ A = 904.32 \, \text{cm}^2 \][/tex]
Therefore, the surface area of the cylinder is [tex]\( 904.32 \, \text{cm}^2 \)[/tex].
The surface area of a cylinder is calculated using the formula A = 2πr² + 2πrh, combining the areas of the top and bottom circles and the side surface.
Explanation:To find the surface area of a cylinder, we need to add the areas of the two circular bases and the lateral surface area. The formula for the surface area of a cylinder is:
A = 2πr2 + 2πrh
where r is the radius of the circular base and h is the height of the cylinder. In this case, you can use a value of ~3.14 for π (pi) and round your answer to the nearest hundredth.
To calculate the surface area of a cylinder, you need to know the radius of the cylinder and its height. The formula for the surface area (A) of a cylinder is A = 2πr² + 2πrh, where r is the radius, and h is the height. This includes both the areas of the top and bottom circles (2πr²) and the area of the side surface (which is the circumference of the circle times the height, 2πrh). If the student provides the dimensions of the cylinder, use them to plug into this formula and calculate the surface area.

If a single marble is pulled out of the bag how many outcomes are in the sample
Answer:10
Step-by-step explanation:
The number of outcomes can vary based on whether the marbles are replaced or not after each draw.
The number of outcomes in the sample space when Maria draws a marble from the bag at random varies depending on the conditions:
If the marbles are replaced after each draw, the sample space remains constant with 7 marbles total (4 blue and 3 white), hence 7 outcomes.If the marble is not replaced, changing the composition to 3 blue and 3 white marbles on the second draw, the sample space then has 6 outcomes.The key factor affecting the number of outcomes is whether the marbles are replaced between draws.

Step-by-step explanation:
Two rival companies began the same year. The equations below model the number of employees, y, at these companies x years after the companies began.
Company R: y = 3x + 24
Company T: y= 4x + 10
Company R stated, “We have 42 employees, the same number of employees as company T has this year.” Determine if company R’s claim is possible. Explain your reasoning.
Company T stated, “After 15 years, we will have the same year of employees as company R.” Determine if company T’s claim is possible. Explain your reasoning.
Answer:
Both the claims by the companies are not possible.
Step-by-step explanation:
Equations modeling number of employees 'y' after 'x' years of the start are,
For company R: y = 3x +24
For company T: y = 4x + 10
If Company R states that this year they have 42 employees,
42 = 3x + 24
3x = 42 - 24
x = [tex]\frac{18}{3}[/tex]
x = 6 years
So company has completed 6 years this year.
Now we put x = 6 years in the equation for company T.
y = (4×6) + 10
y = 24 + 10
y = 34
Which doesn't match with the number of employees of the company R.
Therefore, claim of company R is not possible.
Company T stated that after 15 years they will have the same number of employees as company R.
For company T : y = 4(15) + 10
y = 70 employees
For company R : y = 3(15) + 10
y = 45 + 10
y = 55 employees
Therefore, claim of the company T is also not possible.
Given the equations that model the number of employees y, at these companies x years after the companies began expressed as:
Company R: y = 3x + 24
Company T: y= 4x + 10
If both companies has the same number of employees, then;
3x + 24 = 4x + 10
3x - 4x = 10 - 24
-x = -14
x = 14
Since 14 ≠ 42 that company R claimed, hence the company does not have the same number of employees as company T has this year.
Functions and values
Given the equations that model the number of employees y, at these companies x years after the companies began expressed as:
Company R: y = 3x + 24
Company T: y= 4x + 10
If both companies has the same number of employees, then;
3x + 24 = 4x + 10
3x - 4x = 10 - 24
-x = -14
x = 14
Since 14 ≠ 42 that company R claimed, hence the company does not have the same number of employees as company T has this year.
Since 14 ≠ 15 that company T also claimed, hence the company does not have the same number of employees as company T has this year.

What is the greatest common factor of 4k, 18 Kº, and 12?
A 2
B 4
C 2k.
D
4K
The number 2 is a factor of 4k, 18k and 12 since
4k = 2*2k
18k = 2*9k
12 = 2*6
It is also the largest common factor of all three expressions.
4 wouldn't work because 4 is not a factor of 18
2k doesn't work, and neither does 4k, since k is not present in 12.
The diameter of a cart wheel is 2.1 m. Find the distance traveled when it completes 100 revolutions.
explanation pls!!
Answer
660
Step-by-step explanation:
to find the distance covered in one revolution, we need to find the circumference of the circle.
Radius of wheel is
= 2.1 / 2
= 1.05 m
Distance traveled when 100 revolutions are completed :
= 100 x circumference of the wheel
= 100 x 2 x (22/7) x (1.05)
= 100 x 2 x 22 x 0.15
= 660 m
Distance traveled when it completes 100 revolutions is 659.4 meter
Given that;Diameter of a cart wheel = 2.1 m
Find:Distance traveled when it completes 100 revolutions
Computation:Radius of wheel = 2.1 / 2
Distance traveled when it completes 100 revolutions = [2πr]100
Distance traveled when it completes 100 revolutions = [2(3.14)(2.1 / 2)]100
Distance traveled when it completes 100 revolutions = [(3.14)(2.1)]100
Distance traveled when it completes 100 revolutions = 659.4 meter
