The ratio of the volume of the pyramid to the volume of the prism is 1:1

The formula for calculating the volume of a pyramid is expressed as;

V = 1/3 BH

The formula for calculating the volume of prism is expressed as:

V = Bh

where

B is the base area

H is the height

If the height of pyramid is three times the height of the prism, the volume of pyramis will be:

V = 1/3B * 3h

Take the ratio of their volumes

Vp/Vr  = 3Bh/3Bh
Vp/Vr = 1 : 1

Hence the ratio of the volume of the pyramid to the volume of the prism is 1:1

Answer:

-a^2 + -a + 12

Step-by-step explanation:

Expand the following:

(3 - a) (a + 4)

(3 - a) (a + 4) = (3) (a) + (3) (4) + (-a) (a) + (-a) (4):

-a a + 3 a - 4 a + 3 4

3×4 = 12:

-a a + 3 a - 4 a + 12

-a a = -a^2:

-a^2 + 3 a - 4 a + 12

Grouping like terms, -a^2 + 3 a + 4 (-1) a + 12 = -a^2 + (3 a - 4 a) + 12:

-a^2 + (3 a - 4 a) + 12

3 a - 4 a = -a:

The graph of the line y=4x-3 is attached below.

A graph contains data of which input maps to which output.

Analysis of this leads to the relations which were used to make it.

If we know that the function crosses x-axis at some point, then for some polynomial functions, we have those as roots of the polynomial.

The function is given as y=4x-3

Here the point (0,-3) lies on the line because -3 is the y-intercept(b) in the equation y=mx+b.

Next, we would plot the next point 4 units up and to the right once because 4/1 is rise/run and equal to m in the equation.

Therefore, the graph of the line is attached below.

Answer:

See attachment (red rectangle)

Step-by-step explanation:

Since the upper left is at (-4,4) and upper-right is at (4,4)

The length of the rectangle is

[tex]l = |4 - - 4| = 8[/tex]

Since the perimeter is 20, we have:

[tex]20 = 2(8 + w)[/tex]

[tex]10 = 8 + w[/tex]

[tex]w = 2[/tex]

Therefore we need to draw a rectangle with dimension 8 by 2

Answer:

[tex]g^{-1}[/tex](x) = [tex]\frac{5x+45}{3}[/tex]

Step-by-step explanation:

let y = g(x) and rearrange making x the subject

y = [tex]\frac{3}{5}[/tex] x - 9 ( add 9 to both sides )

y + 9 = [tex]\frac{3}{5}[/tex] x

Multiply both sides by 5 to clear the fraction

5y + 45 = 3x ( divide both sides by 3 )

[tex]\frac{5y+45}{3}[/tex] = x

Change y back into terms of x, thus

[tex]g^{-1}[/tex](x) = [tex]\frac{5x+45}{3}[/tex]

The inverse is g⁻¹(x) = (5/3)*(x + 9)

How to find the inverse?

for a function f(x), the inverse f⁻¹(x) is defined as:

if f(x) = y

f⁻¹(y) = x

For this case, we can write:

g(g⁻¹(x)) = x

(3/5)*g⁻¹(x) - 9 = x

(3/5)*g⁻¹(x) = x + 9

g⁻¹(x) = (5/3)*(x + 9)

Answer: 264 cm^2

Step-by-step explanation:

22*6.5+22*5.5=22*12=264

The area of the given figure  156.75 sq cm.

Step-by-step explanation:

Here,

The figure is a trapezium.

In this trapezium

a = 22 cm

b = 6.5 cm

A and b are the length of two parallel sides.

Height (h) = 5.5 cm

To find the area of the figure which is consists of two trapezium

Formula

Area of the trapezium = [tex]\frac{1}{2} (a+b)h[/tex]

Now,

The area of one trapezium = [tex]\frac{1}{2} (22+6.5)X5.5[/tex] sq cm

= 78.375 sq cm

So,

The area of the figure = 78.375×2 sq cm = 156.75 sq cm

Answer:

[6, 18]

Step-by-step explanation:

the first matrix has the dimensions 1 x 2 (1 row, 2 columns).  The send has the dimensions 2 x 2.  Because of this it is possible to do matrix multiplication and the result will be a 1 x 2 matrix.

Multiply the column -2,  7 by the row 4, 2:

We get (-2)(4) + (7)(2), which simplfies to 6.  This is the first element of the 1 x 2 product.

Multiply the column 5, -1 by the row 4, 2:  We get (5)(4) + (-1)(2), or 18.

The fourth answer choice is the correct one:  [6, 18]

Answer:

Answer:

The amount of sugar actually used by Ashley to bake 6 cookies is 0.15 oz

Step-by-step explanation:

The amount of sugar needed to make 6 cookies = (9/20)  oz

So, the total amount of sugar to be used = (9/20) oz

Let us assume the sugar actually used by Ashley = M oz

Also, given:

Sugar Used  = One third of SUGAR NEEDED

[tex]\implies M = (\frac{1}{3}) \times (\frac{9}{20})[/tex]

            = [tex](\frac{3}{20} )[/tex] = 0.15 oz

or M = 0.15 oz

Hence, the amount of sugar actually used by Ashley to bake 6 cookies is 0.15 oz.

Step-by-step explanation:

The scale factor of the dilation is 2/3. This means that the image point is two-thirds the distance from the original point to the center of dilation.

To find the scale factor of the dilation, we can use the formula:

[tex]\[ \text{scale factor} = \frac{\text{image point}}{\text{original point}} \][/tex]

Given that the image of (6, 9) under the dilation is (4, 6), we can substitute these values into the formula:

[tex]\[ \text{scale factor} = \frac{(4, 6)}{(6, 9)} \]\[ \text{scale factor} = \left( \frac{4}{6}, \frac{6}{9} \right) \][/tex]

Simplifying the fractions:

[tex]\[ \text{scale factor} = \left( \frac{2}{3}, \frac{2}{3} \right) \][/tex]

B. The scale factor is 2/3

To determine the scale factor of the dilation, we need to compare the coordinates of the original point 6, 9 and its image 4 , 6

The formula for dilation of a point x, y by a scale factor k is:

[tex]\[(x', y') = (kx, ky)\][/tex]

Given:

- Original point 6 , 9

- Image point 4 , 6

We need to find the scale factor k such that:

[tex]\[4 = k * 6 \quad \text{and} \quad 6 = k * 9\][/tex]

Let's solve these equations.

1. 4 = 6k

[tex]\[k = \frac{4}{6} = \frac{2}{3}\][/tex]

2. 6 = 9k

[tex]\[k = \frac{6}{9} = \frac{2}{3}\][/tex]

Both equations give the same scale factor of 2/3.

Question

The image of (6, 9) under a dilation is (4, 6).

The scale factor is

A. -2

B 2/3

C -2/3

Answer:

It will be 1 0/4

After using some of her ribbon for a project and a bow, Jenna has 1 meter of ribbon left on the spool.

Jenna has a spool that contains 5 and 3/4 meters of ribbon. She uses 3 and 2/4 meters for a school project and 1 and 1/4 meters for a bow. To find out how much ribbon remains on the spool, we need to subtract the total amount of ribbon used from the initial amount.

First, let's simplify the fractions. 3 and 2/4 meters can be simplified to 3 and 1/2 meters because 2/4 is equivalent to 1/2.

Next, we add the lengths of ribbon used for the project and the bow together: 3 and 1/2 meters + 1 and 1/4 meters = 4 and 3/4 meters.

Finally, we subtract this amount from the total amount of ribbon Jenna had: 5 and 3/4 meters - 4 and 3/4 meters = 1 meter.

Therefore, after using ribbon for a school project and a bow, Jenna has 1 meter of ribbon left on the spool.

Answer: x = 9 -3y

Step-by-step explanation:

Hi, to answer this question we have to solve the system by substitution:

a)3x − 4y = 12

b)2x + 6y = 18

If we isolate "y" on b)

2x + 6y = 18

2x = 18 -6y

x = 18/2 - 6/2y

x = 9 -3y is a possible equation

Doing the same thing with the other equation a) , and isolating "y" in both expressions, the only possible equation is the one founded above.

a) 6x - 5y = 10x + 7 SOLVING FOR X:

6x-5y=10x+7

−5y=10x+7−6x

−5y=4x+7

−5y−7=4x next divide both sides by four and switch sides

[tex]\frac{-5y-7}{4} =x[/tex]

[tex]x=\frac{-5y-7}{4}[/tex]

a) 6x - 5y = 10x + 7 SOLVING FOR Y:

6x-5y=10x+7

−5y=10x+7−6x then simplify

−5y=4x+7, now divide both sides by negative five

[tex]y=\frac{4x+7}{5}[/tex]

b) -4 +(-3) -(-9)

The red dot on the number line represents the value [tex]\(\frac{4}{5}\)[/tex], corresponding to option C.

In a fraction, the numerator (4) denotes the number of parts considered, while the denominator (5) indicates the total number of equal parts in one whole.

Thus, [tex]\(\frac{4}{5}\)[/tex] signifies four parts out of five, placing the red dot closer to the whole number 1 but not reaching it.

This representation aligns with the fraction's numerical value, emphasizing the position of the red dot on the number line and its fractional significance in relation to the unit interval.

Hence, the correct answer is Option C. 4/5

Determining the value of the red dot requires analyzing its position on the number line relative to specific landmarks and measurements provided; however, without the visual of the number line, a precise answer cannot be given.

The value of the red dot on the number line can be determined based on its position relative to the given reference points. The various descriptions of dots' positions involve a comparison to Car X and Car Y figures, as well as precise measurements in terms of perpendicular hash marks on a graph. To ascertain the value that the red dot represents, we must closely examine its placement on the number line in comparison to these references. However, it's crucial to have a visual representation of the number line to provide an accurate value. The mentioned descriptions such as 'the third dot is about one and two-thirds perpendicular hash marks to the right of the center top perpendicular hash mark' indicate the need to understand measuring units and relative positioning on the number line.
