4. A rectangular garage has a volume of 480 m, a length of 12 m and a width of 8 m. What isthe height of the garage?
Answers
Answer:
5 m
Explanation:
The volume of the rectangular garage can be calculated as:
[tex]\text{Volume }=\text{Length }\times\text{ Width }\times\text{ Height}[/tex]If we replace Volume by 480, Lenght by 12, and Width by 8, we get:
[tex]480=12\times8\times\text{ Height}[/tex]Now, we can solve the equation for the Height as:
[tex]\begin{gathered} 480=96\times\text{ Height } \\ \frac{480}{96}=\frac{96\text{ }\times Height}{96} \\ 5=\text{Height} \end{gathered}[/tex]Therefore, the height of the garage is 5 m

Answers
We need to know about area and perimeter of a rectangle to solve the problem. The perimeter of the garden as a percentage of its area is 50.5%
The perimeter of a rectangle is the total of all it's sides. The perimeter can be calculated by adding up the sides of the rectangle. The area of a rectangle can be calculated by multiplying the length with the breadth of the rectangle. The diagonal and width of a rectangle are given, we need to find the length using Pythagoras' theorem.
diagonal =11.5m
width=7 m
length=[tex]\sqrt{11.5^{2} -7^{2} }[/tex]=[tex]\sqrt{132.25-49} =\sqrt{83.25}[/tex]=9.12 m
perimeter=2x(l+b)=32.24 m
area= lxb= 9.12x7=63.84 [tex]m^{2}[/tex]
perimeter as percentage of area=32.24/63.84 x100=50.5%
Therefore the perimeter of the rectangle as a percentage of area is 50.5%.

The first step is to label the points being (1,2.3),(6,6.8) in which the first ordered pairs is the number of weeks, and the second one is the dollars in millions.
Hence, the slope is: m=(6.8-2.3)/(6-1) = 4.5/5 = 9/10 = 0.9
The slope represents the dollar rate in the millions per week. In this case, the movie grossed $0.9 million per week from week one to the sixth week.
determine the length of . question 15 options: a) 9.17 units b) 6.32 units c) 3.74 units d) 10.77 units
Answers
The length of CD is 6.32 units.
From the question, we have
CB / AB = DB / CB
CB / 14 = 10 / CB
CB² = 14 × 10
CB = √140
using the Pythagorean theorem,
AB² = CB² + AC²
14² = (√140)² + AC²
196 - 140 = AC²
AC = √56
Using the ratio of the similar triangle,
CD / AC = DB / CB
CD / √56 = 10 / √140
CD = (√56 × 10)/√140
CD = 6.32 units
the length of CD is 6.32 units.

The point of maxima and minima of any function can be known by equating its derivative to zero. The rocket will take 1.5 sec to reach the maximum height and the maximum height is 27 feet.
What is differentiation?The differentiation of a function is defined as the rate change of its value at around a point. It can be written in mathematical form as g'(x) = (g(x + h) - g(x)) /(x + h - x).
Its geometric meaning is that it is the slope of the function at a given point.
Given that,
Initial height of the launching pad is 4 feet,
Initial velocity of rocket is 48 feet/sec,
Height of the rocket as a function of time, h(t) = -16t² + 48t + 3
In order to find the time for maximum height equate h'(t) = 0 as follows,
-32t + 48 = 0
⇒ t = 48 / 32
⇒ t = 3 / 2
⇒ t = 1.5
To find the maximum height find h(t) for t = 1.5 as follows,
h(1.5) = -16 × 1.5² + 48 × 1.5 + 3
= -36 + 60 + 3
= -36 + 63
= 27
Hence, the time taken by the rocket to reach the maximum height is 1.5 sec and the maximum height reached is 27 feet.

Using the paths shown, how long is the shortest route from Hampton to Lexington?
Answers
In this case, we have to add mixed numbers to find the shortest path from the shown alternatives. We need to work with mixed numbers, fractions, and even decimals.
To answer this question, we know that:
1. The path from Hampton to Middletown is 8 + 1/4 mi.
2. Now, we have two alternatives to go from Middletown to Campbell:
First, we have a path that is equivalent to 6 + 1/8 mi (direct). On the other path, we need to go from Middletown to Danville, and then to Campbell. The measure of the latter path is then:
[tex]3\frac{3}{8}+3\frac{3}{8}=(3+\frac{3}{8})+(3+\frac{3}{8})=(\frac{8\cdot3+3\cdot1}{8})+(\frac{8\cdot3+3\cdot1}{8})[/tex]Thus, we have:
[tex]\frac{(24+3)}{8}+\frac{(24+3)}{8}=\frac{27+27}{8}=\frac{2\cdot(27)}{8}=\frac{2}{8}\cdot27=\frac{1}{4}\cdot27=\frac{27}{4}[/tex]Which is equivalent to:
[tex]\frac{27}{4}=\frac{24}{4}+\frac{3}{4}=6+\frac{3}{4}=6\frac{3}{4}=6.75mi[/tex]If we compare the measures of the two paths, we have that:
a. The path from Middletown to Campbell (directly) is equal to:
[tex]6\frac{1}{8}=6+\frac{1}{8}=6.125mi[/tex]b. The path from Middletown to Danville, and then from Danville to Campbell is equal to 6.75 miles (it is longer).
Therefore, the shortest path, in this part of the "journey", is equal to 6.125 miles or 6 + 1/8 miles.
Now, the complete measure of the path from Hamptom to Lexington is the sum of:
1. The measure of the path from Hamptom to Middletown (8 + 1/4 miles) plus
2. The measure of the path from Middletown to Campbell (6 + 1/8 miles) (directly) plus
3. The measure of the path from Campbell to Lexington (5 + 3/4 miles).
And this is, numerically, as follows:
[tex](8+\frac{1}{4})+(6+\frac{1}{8})+(5+\frac{3}{4})=8+6+5+\frac{1}{4}+\frac{3}{4}+\frac{1}{8}[/tex][tex]19+\frac{4}{4}+\frac{1}{8}=19+1+\frac{1}{8}=20+\frac{1}{8}=20\frac{1}{8}mi[/tex]We can express the latter result as a fraction as follows:
[tex]20+\frac{1}{8}=\frac{20\cdot8+1\cdot1}{8}=\frac{160+1}{8}=\frac{161}{8}mi[/tex]Therefore, the shortest route from Hamptom to Lexington is:
1. As a fraction:
[tex]\frac{161}{8}mi[/tex]2. Or as a mixed number:
[tex]20\frac{1}{8}mi[/tex][Notice that we sum two fractions with the same denominator above:
[tex]\frac{1}{4}+\frac{3}{4}=\frac{3+1}{4}=\frac{4}{4}=1[/tex].]

To solve the equation:
[tex]-15\csc ^2x-1=-32\cot x[/tex]We meed to remember the identity:
[tex]\csc ^2x=\cot ^2x+1[/tex]Plugging this identity in the equation we have:
[tex]\begin{gathered} -15(\cot ^2x+1)-1=-32\cot x \\ -15\cot ^2x-15-1=-32\cot x \\ 15\cot ^2x-32\cot x+16=0 \end{gathered}[/tex]Hence we have the quadratic equation in the cotangent:
[tex]15\cot ^2x-32\cot x+16=0[/tex]To solve it let:
[tex]w=\cot x[/tex]Then we have the quadratic equation:
[tex]15w^2-32w+16=0[/tex]let's use the general formula to solve it:
[tex]\begin{gathered} w=\frac{-(-32)\pm\sqrt[]{(-32)^2-4(15)(16)}}{2(15)} \\ =\frac{32\pm\sqrt[]{1024-960}}{30} \\ =\frac{32\pm\sqrt[]{64}}{30} \\ =\frac{32\pm8}{30} \\ \text{then} \\ w=\frac{32+8}{30}=\frac{40}{30}=\frac{4}{3} \\ \text{ or } \\ w=\frac{32-8}{30}=\frac{24}{30}=\frac{4}{5} \end{gathered}[/tex]Once we know the value of w we can find the value of x, remember the definition of w, then we have:
[tex]\begin{gathered} \cot x=\frac{4}{3} \\ \text{ and} \\ \cot x=\frac{4}{5} \end{gathered}[/tex]Since it is easier to work with the tangent function we will use the fact that:

[tex]\begin{gathered} \tan x=\frac{3}{4} \\ \text{and} \\ \tan x=\frac{5}{4} \end{gathered}[/tex]Finally to solve the equations we need to remember that the tangent function has a period of pi, therefore we have that:

A rectangle with dimensions of 4 units by 5 units is enlarged by a scale factor of 1.2. By what percent does its area increase?
Answers
The area of any shape after dilation is equal to the area of the original shape multiplied by the square of the scale factor:
[tex]A_{\text{new}}=k^2\cdot A_{\text{original}}[/tex]Where
A_new indicates the area of the shape after the dilation
A_original is the area of the original shape
k is the scale factor
The first step is to determine the area of the original shape and the new shape, using the formula:
[tex]A=w\cdot l[/tex]The original shape has dimensions 4 and 5, so its area is:
[tex]\begin{gathered} A_{\text{original}}=4\cdot5 \\ A_{\text{original}}=20 \end{gathered}[/tex]Next is to determine the area of the shape after the dilation (A_new)
The scale factor is k=1.2
[tex]\begin{gathered} A_{\text{new}}=k^2\cdot A_{\text{original}} \\ A_{\text{new}}=(1.2)^2\cdot20 \\ A_{\text{new}}=1.44\cdot20 \\ A_{\text{new}}=28.8 \end{gathered}[/tex]Now that we calculated both areas, we can determine the increase percentage.
- First, calculate the increase (I), which is the difference between the area of the new shape and the area of the original shape:
[tex]\begin{gathered} I=A_{\text{new}}-A_{\text{original}} \\ I=28.8-20 \\ I=8.8 \end{gathered}[/tex]-Second, divide the increase by the original area and multiply the result by 100
[tex]\begin{gathered} \frac{I}{A_{\text{original}}}\cdot100 \\ \frac{8.8}{20}\cdot100 \\ 0.44\cdot100=44 \end{gathered}[/tex]This means that the area increased 44% after the dilation
