Case: Volumes
[tex]\begin{gathered} Volume \\ V=l\times w\times h \end{gathered}[/tex]Where l is length, w is width and h is height.
Given:
Kyle has a storage box that is 2 ft. long, 3 ft. high, and has a volume of 12 ft. 3
Myla has a storage box that is 4 ft. high, 2 ft. long, and has a volume of 16 ft. 3
Method:
For Kyle,
Volume:
[tex]\begin{gathered} V=l\times w\times h \\ 12=2\times w\times3 \\ 12=6w \\ w=\frac{12}{6} \\ w=2ft \end{gathered}[/tex]For Myla,
Volume:
[tex]\begin{gathered} V=l\times w\times h \\ 16=2\times w\times4 \\ 16=8w \\ w=\frac{16}{8} \\ w=2ft \end{gathered}[/tex]The length and width of both boxes are 2ft and 2ft respectively. But they have different heights.
Final answer:
Both have a width of 2ft
Explanation: Same length and width, different heights hence different width

Find the area of the shaded portion of the figures below . Use straight pi= 3.
The area of a circle is given by the following formula:
[tex]A_C=\pi\cdot r^2[/tex]where r is the lenght of the circle's radius.
In this case, we have a radius of 12 units, so the area will be
[tex]A_C=\pi\cdot12^2=3.14\cdot144=452.16[/tex]We are however, asked to find the area of the shaded region, which is encased within a square. From the image we can see that the circle's radius is half the length of a side of the square. In other words, the square's sides measure 24 units.
The area of a square is given by
[tex]A_S=s^2[/tex]where s is the lenght of the sides of the square. In this case,
[tex]A_S=24^2=576[/tex]Now, in order to determine the area of the shaded region, we subtract the area of the circle from the area of the square:
[tex]A_R=A_S-A_C=576-452.16=123.84[/tex]So the area of the shaded region is 123.84 square units.

Point (3,5)
[tex]y(3)=-3+8=5\longrightarrow\text{ is on the line}[/tex]Point (2,10)
[tex]y(2)=-2+8=6\ne10\longrightarrow\text{ is NOT on the line}[/tex]Answer: the point (2,10) is not on the line.
A 6-foot hiker casts a 11-foot shadow, and a nearby tree casts a 34-foot shadow. Find the height of the tree
(round to the nearest tenth).
feet
Answer: 62.33
The ratio of the real length to the shadow is 6:11. to make the first ratio 34 then I could multiply both sides by 34/6 which would make 34:374/6. When 374 is divided by 6 it equals 62 1/3 which also equals 62.33333... Then I would round it to 62.33.

[tex]\begin{gathered} \frac{P1}{P2}=\frac{l1}{l2} \\ \\ \frac{P1}{P2}=\frac{10}{25} \\ \\ P1\colon P2=\frac{2}{5} \\ \\ P1\colon P2=2\colon5 \end{gathered}[/tex]Ratio of their areas become
[tex]\begin{gathered} \frac{A1}{A2}=\lbrack\frac{l1}{l2}\rbrack^2 \\ \\ \frac{A1}{A2}=\lbrack\frac{10}{25}\rbrack^2 \\ \\ \frac{A1}{A2}=\frac{100}{625} \\ \\ \frac{A1}{A2}=\frac{4}{25} \\ \\ A1\colon A2=4\colon25 \end{gathered}[/tex]Out of the 50 people interviewed 6 people said Spider-Man was their favorite super hero. What percent of people said that Spider-Man was their favorite superhero?
To solve find the percentage of people that said Spider-Man was their favorite superhero
We will simply write
[tex]\frac{6}{50}\times\text{ 100\%}[/tex][tex]=\frac{600}{50}percent[/tex]=12%
Therefore; 12% of the people said Spider-Man was their favorite superhero
Which equation represents the ordered pairs in the table? Х у 6 2 12 4 18 6
From the table, we have the following:
[tex]\frac{y}{x}=\frac{2}{6}=\frac{4}{12}=\frac{6}{18}=\frac{1}{3}[/tex]Thus, we have that:
[tex]\frac{y}{x}=\frac{1}{3}\Rightarrow y=\frac{x}{3}\Rightarrow y=\frac{1}{3}x[/tex]We obtain this result if we multiply both sides of the equation by x.
Therefore, the result is:
[tex]y=\frac{1}{3}x[/tex]The answer is the third option.
Question 6 of 14
A researcher creates two random samples, each with a sample size of
10. He
does not find a statistically significant difference between the two groups.
Which of the following statements is correct? Select all that apply.
Correct option is D. Since sample size is 10, the sample size is not adequate, the conclusion is likely to be untrue.
What is meant by sample size?The process of deciding how many observations or replicates to include in a statistical sample is known as sample size determination. Any empirical study with the aim of drawing conclusions about a population from a sample must take into account the sample size as a crucial component.
The quantity of completed survey replies is known as the sample size. Because it merely reflects a portion of the target population (or set of people whose ideas or behavior you are interested in), it is known as a sample.
How is the sample size determined?The equation reads Sample Size = N / (1 + N*e2), where N is the population size.
Be aware that this is the least desirable and least precise formula.

Solve for angle FGD
Answer:
m∠FGD = 132°
Step-by-step explanation:
Corresponding Angles Postulate
When a straight line intersects two parallel straight lines, the resulting corresponding angles are congruent.
Therefore, as AB is parallel to CD, and line EH intersects them:
⇒ m∠EFB = m∠FGD
Substitute the given expressions for the angles and solve for x:
⇒ (3x - 120)° = (x + 48)°
⇒ 3x - 120 = x + 48
⇒ 3x - 120 - x = x + 48 - x
⇒ 2x - 120 = 48
⇒ 2x - 120 + 120 = 48 + 120
⇒ 2x = 168
⇒ 2x ÷ 2 = 168 ÷ 2
⇒ x = 84
Substitute the found value of x into the expression for m∠FGD:
⇒ m∠FGD = (84 + 48)°
⇒ m∠FGD = 132°

The height of the object based on the information is 1963 feet.
How to calculate the height?It should be noted that a function is important to show the relationship between the variables given in the data.
In this case, the function given for the height of the object is given as:
h = 16t² + 1899
where t = time
When the time is 2 seconds, the height will be:
h = 16t² + 1899
h = 16(2)² + 1899
h = 64 + 1899
h = 1963
The height is 1963 feet.
