164.7/8.6 = 19.15
about 20 miles per gallon
The best estimate of the rate of fuel consumption is C, 20 mi/gal
Which is the best estimate for thenumber of miles per gallon of gasoline her vehicle gets?To estimate the rate between miles and gallons, we just need to take the quotient between the given distance and the volume of gasoline consumed. Then we will get the rate:
R = 164.7mi/8.6 gal
R = 19.4 mi/gal
The closest value is the one at option C, which is 20 miles per galon.

do the side lengths 4.1,8.2,and 12.2 for a triangle
Answer:
Step-by-step explanation:
Three line segments can form a triangle if the length of the longest segment is greater than the sum of the lengths of the shorter segments.
4.1 + 8.2 > 12.2
12.3 > 12.2
true
They can form a triangle.
Now if c is the length of the longest side and a and b are the lengths of the shorter sides, then:
- if , [tex]c^{2}[/tex] = [tex]a^2 + b^2[/tex] the triangle is right
- If [tex]c^2 < a^2 + b^2[/tex]
- if [tex]c^2 > a^2 + b^2[/tex] the triangle is obtuse
[tex]4.1^2 + 8.2^2 = 16.81 + 67.24 = 84.05\\12.2^2 = 148.84\\148.84 > 84.05[/tex]

Examples of skew lines
Answer:
An example of skew lines are the sidewalk in front of a house and a line running across the top edge of a side of a house.
Step-by-step explanation:
:D
Final answer:
Skew lines are lines that do not intersect and are not parallel. Examples include a ladder leaning against a wall, non-parallel railway tracks, and a pencil and a ruler placed randomly on a table.
Explanation:
Skew lines are lines that do not intersect and are not parallel. They are in the same plane but do not lie on the same line. One example of skew lines is a ladder leaning against a wall. The ladder and the wall are in the same plane, but they do not intersect and are not parallel.
Another example of skew lines is a pair of non-parallel railway tracks. The tracks are in the same plane, but they do not intersect and are not parallel.
Finally, a pencil and a ruler placed randomly on a table can also be considered as skew lines. They are in the same plane, but they do not intersect and are not parallel.

A sphere has been placed inside an cylinder with the same dimensions;both have a radius of 6cm,and a height of 12cm How many cubic centimeters of space does the sphere fill not fill up. A.432pi cm B.72 pi cm C.288 pi cm D.144 pi cm
Answer:
D
Step-by-step explanation:
Final answer:
To find the cubic centimeters of space not filled by the sphere in the cylinder, subtract the volume of the sphere (288π cm³) from the volume of the cylinder (432π cm³), yielding 144π cm³. Therefore, the correct answer is D. 144π cm³.
Explanation:
To determine how many cubic centimeters of space the sphere does not fill in the cylinder, we first need to calculate the volume of the cylinder and then subtract the volume of the sphere from it.
The volume of a cylinder is given by the formula V = πr²h, where r is the radius and h is the height. In this case, with a radius of 6 cm and height of 12 cm, the volume is:
[tex]V_{cylinder}[/tex] = π × (6 cm)² × 12 cm = 432π cm³.
The volume of a sphere is given by the formula V = 4/3 πr³. With a radius of 6 cm, the volume is:
[tex]V_{sphere[/tex] = 4/3 π × (6 cm)³ = 288π cm³.
The space the sphere does not fill up in the cylinder is:
Space not filled = [tex]V_{cylinder}[/tex] - [tex]V_{sphere[/tex] = 432π cm³ - 288π cm³ = 144π cm³.
Therefore, the answer is D. 144π cm³.

Isabelle stacked two wooden blocks as shown. What is the volume of the stacked blocks?
Part 1:-
=> Volume of cuboid = lbh
=> Volume of cuboid = 3 × 16 × 2
=> Volume of cuboid = 6 × 16
=> Volume of cuboid = 96 cm³
Part 2:-
=> Volume of traingle = bh
=> Volume of traingle = 10 × 4
=> Volume of traingle = 40 cm³
Now,
→ Total Volume = Vol. of cuboid + Vol. of traingle
→ Total Volume = 96 + 40
→ Total Volume = 136 cm³

Answer:

Answer:
Total lateral surface of the pyramid = 54 [tex]cm^{2}[/tex]
which agrees with the first listed answer.
Step-by-step explanation:
Notice that the pyramid has for base an equilateral triangle of base 5 cm, and has three lateral triangles which have all the same dimensions for their base (5 cm - since they are all connected to the base of the pyramid), and their height (7.2 cm).
The actual LATERAL surface, includes only the surface of the three lateral triangles.
We use the formula for the area of a triangle: [tex]Area=\frac{base \,*\, height}{2}[/tex]
to calculate the area of each lateral triangle:
[tex]Area=\frac{5\,cm \,*\, 7.2\,cm}{2} \\Area=18 \,cm^2[/tex]
and then multiply the result by three (to account for the three lateral faces)
Therefore, the total lateral surface is:
Total lateral surface = 3 * 18 = 54 [tex]cm^{2}[/tex]

The value of the expression is Option a. -7.
To find the value of the rational expression (2x² + 5x + 9) / (x² + 2x - 1) when x = -2, we need to substitute -2 into the expression.
First, let's calculate the numerator:
2(-2)² + 5(-2) + 9= 2(4) -10 + 9= 8 - 10 + 9= 7Next, we calculate the denominator:
(-2)² + 2(-2) - 1= 4 - 4 - 1= -1Now, we divide the numerator by the denominator:
= 7 / (-1)= -7So, the value of the rational expression when x = -2 is -7. Therefore, the correct answer is Option a. -7.

3. Of the three expressions shown, which two
are equivalent?
3+2(9 + 2n) 7(3 + 4n) 21 + 4n
Answer:
the answer would be the first and last equation
Step-by-step explanation:
both equations equal 21+4n
Final answer:
After simplifying the expressions, it's found that 3 + 2(9 + 2n) simplifies to 21 + 4n, and the third expression is exactly 21 + 4n. These two expressions are equivalent.
Explanation:
To determine which two of the three expressions are equivalent, we need to simplify each expression and compare them.
Let's simplify each expression:
3 + 2(9 + 2n) = 3 + 18 + 4n = 21 + 4n
7(3 + 4n) = 21 + 28n
21 + 4n = 21 + 4n
Now, we can compare them:
The first expression, after simplification, becomes 21 + 4n.
The second expression is 21 + 28n, which is not equivalent to the first.
The third expression is exactly 21 + 4n, which is equivalent to the first expression.
So, the expressions 3 + 2(9 + 2n) and 21 + 4n are equivalent.

In a sample of voters in Harrisburg, 18 out of 25 favored creating a new shopping center. If 50,000 people vote in the next Harrisburg election, how many are likely to vote in favor of the new shopping center based on this sample?
Answer:
36,000 people are likely to vote in favour of the new shopping centre
Step-by-step explanation:
Given
Population = 50,000
Total Sample = 25
18 favoured opening a new shopping centre
Required
Likely number of people to vote in favor of the new shopping center.
First, we need to represent the sample in proportion.
Let p represent the proportion
Since 18 out of 25 are in support of opening a new center,
p = 18/25
Having solved for the proportion,the next step is to calculate the expected number of people.
This is calculated by multiplying p by the total population.
Given that population = 50,000
The expected outcome = 18/25 * 50,000
Expected outcome = 18 * 2,000
Expected outcome = 36,000
Hence, 36,000 people are likely to vote in favour of the new shopping centre
Answer:
36,000 voters
Step-by-step explanation:
Here we have a question on proportion
Proportion of voters that favored creating a new shopping center = 18/25
That is the point estimate of voters that favored creating a new shopping center = 18/25
Therefore, among 50,000 voters in Harrisburg the number of voters that are likely to vote in favor of the new shopping center, based on the point estimate of the sample is given by the following expression;
18/25 × 50,000 = 36,000 voters.

Answer:
To find the expression for the box, we need to simplify the equation. Let's break it down step by step:
3 (x + 1) + 9 = box
First, distribute the 3 to the terms inside the parentheses:
3x + 3 + 9 = box
Next, combine like terms:
3x + 12 = box
Now, we can compare the simplified equation to the given expressions:
3 (x + 4)
2 (x + 6) + x
4(x – 3) – x
3 (x + 1) + 9
We are looking for an expression that matches our simplified equation, which is 3x + 12. By comparing the expressions, we can see that 3 (x + 1) + 9 is the same as 3x + 12.
Therefore, the expression that can be written in the box is 3 (x + 1) + 9.
