(a) d = 200 ft
(b) t = d/40 sec
EXPLANATION
The animal is running at a rate of 40 feet per second. Given the units of this rate, we can conclude that this rate is the quotiend between distance (in feet) and time (in seconds),
[tex]40\frac{ft}{sec}=\frac{d}{t}[/tex](a) Now, if the animal runs for a time t = 5 seconds, we have to find what is its distance traveled, d. To do so, we solve the expression above for d by multiplying both sides by t,
[tex]d=40\frac{ft}{sec}\cdot t=40\frac{ft}{sec}\cdot5sec=200ft[/tex]Hence, in 5 seconds the animal travels 200 feet.
(b) For this part of the question, we have to find the other variable, t, knowing that the distance traveled is d. Since the distance is not given as a number, we will find an expression as a function of d,
[tex]40\frac{ft}{sec}=\frac{d\text{ }ft}{t}[/tex]Solving for t,
[tex]t=\frac{d\text{ }ft}{40\frac{ft}{sec}}[/tex]The unit of distance, feet, cancels out, and we have the result in seconds,
[tex]t=\frac{d}{40}\text{ }sec[/tex]Hence, the time for a distance traveled of d feet is d/40 sec.
what are three equivalent Ratios for 8/10
Answer: 16/20, 24/30, and 32/40
We are given a ratio of 8 to 10
[tex]\begin{gathered} \frac{8}{10} \\ \text{ To find the equivalent ratios, the numerator must be a multiple of 8 and the denominator must be a multiple of 10} \\ \text{Multiple of 8: 8 x 1, 8 x 2, 8 x 3, }8\text{ x 4} \\ \text{Multiple of 8: 8, 16, 24, 32} \\ \text{Multiple of 10: 10 x 1, 10 x 2, 10 x 3, 10 x 4} \\ \text{Multiple of 10: 10, 20, 30, 40} \\ \text{For 8 : 10} \\ \frac{8}{10\text{ }}\text{ = }\frac{4}{5} \\ \frac{16}{20}\text{ = }\frac{4}{5} \\ \frac{24}{30}\text{ = }\frac{4}{5} \\ \frac{32}{40}\text{ = }\frac{4}{5} \end{gathered}[/tex]Therefore, the equivalent ratios for 8/10 are 16/20, 24/30, and 32/40

In order to solve this question it's useful to remember that the sum of the internal angles of a triangle is equal to 180°.
Firstly, let's take a look at the angles which have D as their vertex. These two angles are BDC and BDA and they both share a side whereas their remaining sides are in the same line. This means that these two are supplementary which means that their sum is equal to 180°. Knowing that the measure of BDC is equal to 90° we get:
[tex]\begin{gathered} BDC+BDA=90^{\circ}+BDA=180^{\circ} \\ 90^{\circ}+BDA=180^{\circ} \end{gathered}[/tex]If we substract 90° from both sides:
[tex]\begin{gathered} 90^{\circ}+BDA-90^{\circ}=180^{\circ}-90^{\circ} \\ BDA=90^{\circ} \end{gathered}[/tex]So both angles are right angles.
Having found the measure of angle BDA let's take a look at triangle BDA. We have a 45° angle, a 90° angle and angle b. Since the sum of these 3 must be equal to 180° so we get:
[tex]\begin{gathered} b+45^{\circ}+90^{\circ}=180^{\circ} \\ b+135^{\circ}=180^{\circ} \end{gathered}[/tex]Then we substract 135° from both sides:
[tex]\begin{gathered} b+135^{\circ}-135^{\circ}=180^{\circ}-135^{\circ} \\ b=45^{\circ} \end{gathered}[/tex]So we have found b. We still need to find a. Let's take a look at vertex B. The external angle is equal to 275° whereas there are two internal angles: a 45° angle and angle DBC. The sum of the external and internal angles in a vertex must be equal to 360° then we have:
[tex]\begin{gathered} 360^{\circ}=275^{\circ}+45^{\circ}+DBC=320^{\circ}+DBC \\ 360^{\circ}=320^{\circ}+DBC \end{gathered}[/tex]If we substract 320° from both sides we get:
[tex]\begin{gathered} 360^{\circ}-320^{\circ}=320^{\circ}+DBC-320^{\circ} \\ 40^{\circ}=DBC \end{gathered}[/tex]Now that we have angle DBC we can find angle a by looking at triangle BDC. The sum of its internal angles is 180° and we already know two of them: DBC and BDC. Then we get:
[tex]\begin{gathered} 180^{\circ}=DBC+BDC=40^{\circ}+90^{\circ}+a=130^{\circ}+a \\ 180^{\circ}=130^{\circ}+a \end{gathered}[/tex]Then if we substract 130° from both sides we get:
[tex]\begin{gathered} 180^{\circ}-130^{\circ}=130^{\circ}+a-130^{\circ} \\ a=50^{\circ} \end{gathered}[/tex]So now we know that a=50° and b=45°. Then a is bigger than b by 5° and the answer is option c.
How do you do this? I know how to figure out C but im not sure about B?
Answer: 50
Step-by-step explanation: i Think..
⇒To figure out b you have already been given an equation :[tex]a^{2} +b^{2} =c^{2}[/tex]

A) Find the circumference of a circle whose radius is 4 inches.Round to the nearest tenth.B) Find the length of AB, if m
Given:
• Radius of the circle, r = 4 inches
,• Central angle, m∠ACB = 60 degrees
Let's solve for the following:
• (A). Find the circumference of a circle whose radius is 4 inches.
To find the circumference, apply the formula:
[tex]C=2\pi r[/tex]Where:
C is the circumference.
r is the radius = 4 inches.
Plug in 4 for r and solve for r:
[tex]\begin{gathered} C=2\pi *4 \\ \\ C=25.1\text{ inches} \end{gathered}[/tex]Therefore, the circumference of the circle is 25.1 inches.

[tex]\begin{gathered} L=2\pi r*\frac{\theta}{360} \\ \\ L=C*\frac{\theta}{360} \end{gathered}[/tex]Where:
θ is the central angle = 60 degrees.
C is the circumference.
Thus, we have:
[tex]\begin{gathered} L=25.1*\frac{60}{360} \\ \\ L=25.1*\frac{1}{6} \\ \\ L=4.18\approx4.2\text{ inches} \end{gathered}[/tex]Therefore, the length of the arc is 4.2 inches.
ANSWER:

The given equation is expressed as
4^2 + 4^2 = c^2
Recall, for a right angle triangle, we can apply the pythagorean theorem which is expressed as
opposite side^2 + adjacent side^2 = hypotenuse^2
The hypotenuse is the longest side
By comparing with the options, only the second option is a right angle triangle. The hypotenuse is C. The opposite side is 4 and the adjacent side is also 4.
Thus, the correct option is the second option
Which equation represents a line which is parallel to the line y = 3x - 8x + y = 18x - 3y = -123x + y = 6y - 3x = 7
Parallel equations have the same slope. First, let's identify the slope of the given equation, which is in the slope-intercept form:
[tex]y=mx+b[/tex]Where m is the slope and b is the y-intercept.
Comparing the given equation with this form, we have m = 3, so the slope is 3.
Now, let's identify the slope of each option:
[tex]\begin{gathered} x+y=18\\ \\ y=-x+18\\ \\ m=-1 \end{gathered}[/tex][tex]\begin{gathered} x-3y=-12\\ \\ 3y=x+12\\ \\ y=\frac{1}{3}x+4\\ \\ m=\frac{1}{3} \end{gathered}[/tex][tex]\begin{gathered} 3x+y=6\\ \\ y=-3x+6\\ \\ m=-3 \end{gathered}[/tex][tex]\begin{gathered} y-3x=7\\ \\ y=3x+7\\ \\ m=3 \end{gathered}[/tex]Therefore the correct option is the fourth one: y - 3x = 7.

[tex]undefined[/tex]Jennifer works 3 1/2 hours eachmorning at the clinic How manyRoutine physicals could she compete in one morning? Serious injury 1 1/4 hrsDental scaling 3/4 hrs Routine physicals 1/3 hrs.Sick Animal visit 1/2 hrNew patient 3/4 hrs Immunizations 1/4 hrs
Answer
Jennifer can perform 10 Routine Physicals in the morning
Solution
- The question tells us that Jennifer works 3 1/2 hours each morning and we are asked to find how many Routine physicals she can perform in the morning if 1 Routine physical takes 1/3 hours.
- In order to find the number of Routine physicals that can be performed in 3 1/2 hours, we simply need to assume that Jennifer can perform n number of Routine physicals. That is:
[tex]\begin{gathered} \text{ Total number of Routine physicals:} \\ \frac{1}{3}+\frac{1}{3}+\frac{1}{3}+\cdots=n\times(\frac{1}{3}) \\ \text{ } \\ \text{ If we take this as the total number of Routine Physicals possible within }3\frac{1}{2}\text{ hours, and r is the number } \\ \text{ of minutes left before }3\frac{1}{2}\text{ hours are completed, we have:} \\ \\ \frac{1}{3}+\frac{1}{3}+\frac{1}{3}+\cdots+r=3\frac{1}{2}=\frac{(3\times2)+1}{2}=\frac{7}{2} \\ \\ \therefore n\times(\frac{1}{3})+r=\frac{7}{2} \end{gathered}[/tex]Thus, to find the number of Routine Physicals, n, we simply make n the subject of the formula:
[tex]\begin{gathered} n=3(\frac{7}{2}-r) \\ \\ \text{This implies that the number of Routine Physicals is divisible by 3. This means that n is a multiple of 3} \\ \text{Thus, we can test values with multiples of 3.} \\ \\ \text{when n = 3:} \\ 3\times(\frac{1}{3})=1\text{hour} \\ \\ \text{when n= 6}\colon \\ 6\times(\frac{1}{3})=2\text{hours} \\ \\ \text{when n = 9:} \\ 9\times(\frac{1}{3})=3\text{hours} \\ \\ \text{when n= 12:} \\ 12\times(\frac{1}{3})=4hours \\ \\ \text{This implies that the number of Routine Physicals cannot be greater than or equal to 12. It also } \\ \text{implies that the number of Routine Physicals cannot be less than 9 since 9 physicals would take} \\ 3\text{ hours.} \\ \\ This\text{ means that the number of possible hours is between 10 or 11.} \\ \\ when\text{ n = 10:} \\ 10\times(\frac{1}{3})=3+\frac{1}{3}\text{ hours}<3\frac{1}{2}\text{ hours} \\ \\ \text{when n = 11:} \\ 11\times(\frac{1}{3})=3+\frac{2}{3}\text{ hours}>3\frac{1}{2}\text{ hours} \\ \\ \text{Thus, we can conclude that Jennifer can only do 10 Routine Physicals in the morning} \end{gathered}[/tex]Final answer
Jennifer can perform 10 Routine Physicals in the morning

X is the opposite angle of a
now put all the values
[tex]X=\cos^{-1}(\frac{110^2+100^2-70^2}{2*110*100})=38.57\degree[/tex]Final answer:

A Ferris Wheel has a center of 85 feet off the ground and the highest car sits 166 feet off the ground.
As the highest car sits 166 feet off the ground. the radius of the circle is equal to the difference between that heigth and the center of the ferris:
[tex]\begin{gathered} r=166ft-85ft \\ \\ r=81ft \end{gathered}[/tex]The radius is 81 feetThe lowest a cat will sit is the difference between the center of the circle and the radius:
[tex]85ft-81ft=4ft[/tex]The lowest a car will sit on the Ferris wheel is 4ftA professor went to a website for rating professors and looked up the quality rating and also the "easiness" of the six full-time professors in onedepartment. The ratings are 1 (lowest quality) to 5 (highest quality) and 1 (hardest) to 5 (easiest). The numbers given are averages for eachprofessor. Assume the trend is linear, find the correlation, and comment on what it means.
We are asked to determine the correlation factor "r" of the given table. To do that we will first label the column for "Quality" as "x" and the column for "Easiness" as "y". Like this:
Now, we create another column with the product of "x" and "y". Like this:
Now, we will add another column with the squares of the values of "x". Like this:
Now, we add another column with the squares of the values of "y":
Now, we sum the values on each of the columns:
Now, to get the correlation factor we use the following formula:
[tex]r=\frac{n\Sigma xy-\Sigma x\Sigma y}{\sqrt{(n\Sigma x^2-(\Sigma x)^2)(n\Sigma y^2-(\Sigma y)^2)}}[/tex]Where:
[tex]\begin{gathered} \Sigma xy=\text{ sum of the column of xy} \\ \Sigma x=\text{ sum of the column x} \\ \Sigma y=\text{ sum of the column y} \\ \Sigma x^2=\text{ sum of the column x\textasciicircum2} \\ \Sigma y^2=\text{ sum of the column y\textasciicircum2} \\ n=\text{ number of rows} \end{gathered}[/tex]Now we substitute the values, we get:
[tex]r=\frac{\left(6)(70.56)-(25.2)(16.4\right)}{\sqrt{((6)(107.12)-(25.2)^2)((6)(47.82)-(16.4)^2)}}[/tex]Solving the operations:
[tex]r=0.858[/tex]Therefore, the correlation factor is 0.858. If the correlation factor approaches the values of +1, this means that there is a strong linear correlation between the variables "x" and "y" and this correlation tends to be with a positive slope.

Step 03: Substitute the values in the vertex form.
a = 1
h = 3
k = 16
[tex]\begin{gathered} y=a\cdot(x-h)^2+k \\ y=1\cdot(x-3)^2+16 \\ y=(x-3)^2+16 \end{gathered}[/tex]Answer:
