Answer:

D

Step-by-step explanation:

Remembering that the product of 2 negatives is positive, then

- 25 × - 3 = 75 → D

Final answer:

Upon examining the factor pairs given in the options, none of them correctly multiply to a positive 75. There seems to be a typo in the options as none matches the requirement for the product to be 75. Most likely, the correct factor pair is missing or misrepresented.

Explanation:

The question asks to identify which factor pair has a product of 75. To find factors of 75, we look for pairs of numbers that multiply together to give the product of 75. Remember, the product of two negative numbers is positive.

Option A (25 and -3) does not give 75 as a product because 25 multiplied by -3 is -75.

Option B (-15 and 5) gives us a product of 75, since -15 multiplied by 5 is -75 (but we are looking for a positive 75).

Option C (-75 and 1) is incorrect because it results in -75, not 75.

Option D (-25 and -3) is also incorrect, as the product of two negative numbers would be positive, but it results in +75.

However, upon reviewing the options provided, it appears none of them correctly multiply to a positive 75. Most likely, there is a typo in the question or the options presented. In mathematics, finding factors of a number means identifying two numbers that, when multiplied together, give the original number. While option B's multiplication gives a product of -75, it is close to our target; we need a positive value, i.e., 75, not -75.

Answer:

36π cm³

Step-by-step explanation:

The volume (V) of a sphere is calculated using the formula

V = [tex]\frac{4}{3}[/tex]πr³ ← r is the radius = 3

V = [tex]\frac{4}{3}[/tex]π × 3³

  = [tex]\frac{4}{3}[/tex]π × 27

  = 4π × 9 ( cancelling the 3 and 27 )

  = 36π cm³

Here is your answer

B) [tex]36×pi[/tex] [tex]{cm}^{3}[/tex]

REASON:

We know that,

Volume of sphere= [tex] 4/3 pi×{r}^{3} [/tex]

Here r= 3cm

So, V= [tex] 4/3 × pi× {3}^{3} cm^3 [/tex]

= [tex] 4×pi × {3}^{2} cm^3 [/tex]

= [tex] 4×9× pi cm^3 [/tex]

= [tex] 36× pi cm^3 [/tex]

3577+5214+5879

=8791+5879

=14670

Answer

B. 14,670

The total number of seats in all three levels of the auditorium is calculated by adding the number of seats on each level, resulting in 14,670 seats.

To calculate the total number of seats in all three levels of the auditorium, we add the number of seats available on each level together. The calculation is as follows:

Level 1: 3,577 seats

Level 2: 5,214 seats

Level 3: 5,879 seats

Add these numbers to get the total:

3,577 + 5,214 + 5,879 = 14,670 seats

Therefore, the correct answer is B. 14,670, which is the combined number of seats in all three levels of the auditorium.

Tina will need 64 cardboard building blocks to build the wall.

Step 1: Convert all measurements to inches.

The thickness of the wall is already 4 inches.

The height of the wall is 3 feet. Since 1 foot = 12 inches, then:

[tex]3 \text{ feet} = 3 \times 12 \text{ inches} = 36 \text{ inches}[/tex]

The length of the wall is 12 feet. Therefore:

[tex]12 \text{ feet} = 12 \times 12 \text{ inches} = 144 \text{ inches}[/tex]

Step 2: The volume of a rectangular wall can be found using the

formula:

[tex]\text{Volume} = \text{Length} \times \text{Height} \times \text{Thickness}[/tex]

Substituting the values:

[tex]\text{Volume} = 144 \text{ inches} \times 36 \text{ inches} \times 4 \text{ inches}[/tex]

[tex]\text{Volume} = 20736 \text{ cubic inches}[/tex]

Step 3: The dimensions of the block are 9 inches x 9 inches x 4 inches,

so:

[tex]\text{Volume}_{\text{block}} = 9 \text{ inches} \times 9 \text{ inches} \times 4 \text{ inches}[/tex]

[tex]\text{Volume}_{\text{block}} = 324 \text{ cubic inches}[/tex]

Step 4: To find out how many blocks are needed for the wall, divide the

total volume of the wall by the volume of one block:

[tex]\text{Number of blocks} = \frac{\text{Volume of wall}}{\text{Volume of one block}}[/tex]

[tex]\text{Number of blocks} = \frac{20736 \text{ cubic inches}}{324 \text{ cubic inches}}[/tex]

[tex]\text{Number of blocks} = 64[/tex]

Answer: Reserved = 431, General Admission = 1356

Step-by-step explanation:

Let x represent the Reserved tickets.

Let y represent the General Admission tickets.

Cost Equation:        4x + 3y = 5792

Quantity Equation:    x + y = 1787

Use Elimination Method:

4x + 3y = 5792  →   1(4x + 3y = 5792)   →   4x + 3y =  5792

 x +   y = 1787   →  -3( x +    y = 1787)    → -3x  - 3y = -5361

                                                                      x         =   431

Now substitute x = 431 into one of the original equations:

x + y = 1787

431 + y = 1787

        y = 1356

Answer:

Option D. [tex]y=-4x^{2} -16x-12[/tex]

Step-by-step explanation:

using a graphing tool

Graph and determine the vertex in each case

we know that

If the equation has a maximum value at x=-2, then the x-coordinate of the vertex must be  equal to -2 and the parabola open downward

case A) [tex]y=-x^{2} -20x-16[/tex]

The vertex is the point [tex](-10,84)[/tex]

case B) [tex]y=-x^{2} -16x-12[/tex]

The vertex is the point [tex](-8,52)[/tex]

case C) [tex]y=-4x^{2} -20x-16[/tex]

The vertex is the point [tex](-2.5,9)[/tex]

case D) [tex]y=-4x^{2} -16x-12[/tex]

The vertex is the point [tex](-2,4)[/tex] -------> is the answer

see the attached figure

The equation with a maximum value at x = -2 is D) y = -4x^2 - 16x - 12, determined by finding the vertex of each quadratic equation and identifying the one with the vertex x-coordinate at -2.

The given equations are all in quadratic form, which can have a maximum value at their vertex point if the leading coefficient is negative. To find the equation that has a maximum value at x = -2, we need to put the equations in vertex form, which is y = a(x - h)^2 + k, where (h, k) is the vertex. By transforming the given equations, we seek the equation that has its vertex at x = -2. This is done by completing the square or using the formula h = -b/(2a) to find the x-coordinate of the vertex.

Let's apply the formula h = -b/(2a) to each equation:

Therefore, the correct equation with a maximum value at x = -2 is D) y = -4x^2 - 16x - 12.

A rigid transformation is a transformation that preserves the shape and size of an object. It includes translations, rotations, and reflections. Without specific information about the coordinates or measurements of the triangles, it is not possible to determine if a rigid transformation exists.

A rigid transformation is a transformation that preserves the shape and size of an object. It includes translations, rotations, and reflections. In order for triangle ΔABC to be mapped to triangle ΔDEC, there must be a combination of translations, rotations, and reflections that can bring the two triangles into congruence.

However, without specific information about the coordinates or measurements of the vertices of the triangles, it is not possible to accurately determine if a rigid transformation exists that can map ΔABC to ΔDEC.

Answer:

D

Step-by-step explanation:

We need to find total area of the two rooms (hexagon and nonagon) and then multiply that by 4.5 to get total cost.

Area of Hexagon = [tex]\frac{3\sqrt{3}a^{2} }{2}[/tex]

Where a is the side length (which is 50)

Hence,

Area of Hexagon = [tex]\frac{3\sqrt{3}a^{2} }{2}=\frac{3\sqrt{3}(50)^{2} }{2}=6495.2[/tex]

Also, area of Nonagon is given by  [tex]6.1818*s^2[/tex]

Where s is the length of the side

Hence,

Area of Nonagon = [tex]6.1818*s^2=6.1818*(50)^2=15,454.5[/tex]

Total floor area = 6495.2 + 15,454.5 = 21,949.7

Hence,

Total Cost = 21,949.7 * 4.5 = 98,773.65

THis is closest to the answer choice D.

Answer:

Step-by-step explanation: 180

I think the answer is 180

The correct answer is 36.

We use the vertical side as the base: it is a vertical segment, so it's length is the difference of the y coordinates of its endpoints:

[tex] b = y_2-y_1[/tex]

The height would be the segment starting from [tex](x_3,y_3)[/tex], perpendicular to the base. Since this is a horizontal segment, its length is the difference of the x coordinates of its endpoints:

[tex]h = x_3-x_1[/tex]

So, the area is given by

[tex]A = \dfrac{bh}{2} = \dfrac{(y_2-y_1)(x_3-x_1)}{2}[/tex]

Answer:

A = 18

Step-by-step explanation:

Drop a perpendicular from (x₃, y₃) to point A on the opposite side.

The vertical line containing A is the base of the triangle, and the horizontal line is its height,

The formula for the area of a triangle is  

A = ½bh

b = y₂ - y₁ = 6

h = x₃ - x₁ = 6

A = ½ × 6 × 6 = 18

The area of the triangle is 18.

Answer:

D

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

To calculate m use the slope formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (0 , 4) and (x₂, y₂ ) = (4, 10)

m = [tex]\frac{10-4}{4-0}[/tex] = [tex]\frac{6}{4}[/tex] = [tex]\frac{3}{2}[/tex]

note the line passes through (0, 4) ⇒ c = 4

y = [tex]\frac{3}{2}[/tex] x + 4 ← equation of line → D

Answer:

To find the answer, you must multiply/divide the amount in cups by calories per cup.

Step-by-step explanation:

Butter only has 0.3 cups, so The calories will only be 30% of what is written down. 30% of 1627= 488.1 calories

Marshmallows is 4.25 times larger then the calories per cup, so now you'll have to multiply.

4.25*159=675.75 calories

Finally, Cereal is 5.5 times larger then the calories per cup, so we will multiply again.

5.5*101=555.5 calories

Finally, add all the number together to find the total amount of calories in the marshmallow treats.

555.5+675.75+488.1=1,719.35  calories

There is a total of 1,719.35 calories in the marshmallow treats.
