The diameter of a truck wheel is 56.5 inches. What is the circumference of
the wheel?
Answer: 177.4999849 , or 56.5pi
Step-by-step explanation:
You simply divide the diameter by 2 to get the radius (28.25) and then plug into the circumference equation, 2*pi*r = Circumfrence.
Answer:
177.5 inches
Step-by-step explanation:
c = 2πr
d = r2
56.5/2=28.25
28.25x3.14= 88.705
88.705x2=177.41
Round, and you’ll get 177.5.

In a class of students, the following data table summarizes how many students have a cat or a dog. What is the probability that a student has a cat given that they do not have a dog? ( NO LINKS )
Given:
Number of students who has a cat and a dog = 5
Number of students who has a cat but do not have a dog = 11
Number of students who has a dog but do not have a cat = 3
Number of students who neither have a cat nor a dog = 2
To find:
The probability that a student has a cat given that they do not have a dog.
Solution:
Let the following events:
A = Student has a cat
B = Do not have a dog
Total number of outcomes is:
[tex]5+3+11+2=21[/tex]
The probability that a student has a cat but do not have a dog is:
[tex]P(A\cap B)=\dfrac{11}{21}[/tex]
The probability that a student do not have a dog is:
[tex]P(B)=\dfrac{11+2}{21}[/tex]
[tex]P(B)=\dfrac{13}{21}[/tex]
The conditional probability is:
[tex]P\left(\dfrac{A}{B}\right)=\dfrac{P(A\cap B)}{P(B)}[/tex]
[tex]P\left(\dfrac{A}{B}\right)=\dfrac{\dfrac{11}{21}}{\dfrac{13}{21}}[/tex]
[tex]P\left(\dfrac{A}{B}\right)=\dfrac{11}{13}[/tex]
Therefore, the probability that a student has a cat given that they do not have a dog is [tex]\dfrac{11}{13}[/tex].

A solid with volume 8 cubic units is dilated by a scale factor of k to obtain a solid with volume V cubic units. Find the value of k which results in an image with each given volume.
a. 216 cubic units
k=
b. 1 cubic unit
k=
c. 1,000 cubic units
k=
Answer:
a. k = 27
b. k = 216
c. k = 0.216
Step-by-step explanation:
The value of the scale factor can be given by the following formula:
[tex]k = \frac{Final\ Volume}{Initial\ Volume}[/tex]
where,
Initial Volume = 8 cubic units
a.
Final Volume = 216 cubic units
Therefore,
[tex]k = \frac{216\ cubic\ units}{8\ cubic\ units}[/tex]
k = 27
b.
Final Volume = 1 cubic units
Therefore,
[tex]k = \frac{216\ cubic\ units}{1\ cubic\ units}[/tex]
k = 216
c.
Final Volume = 1000 cubic units
Therefore,
[tex]k = \frac{216\ cubic\ units}{1000\ cubic\ units}[/tex]
k = 0.216

3(s+4)=s+10+2s
Distribute
3s+12=s+10+2s
Add like terms
3s+12= 3s+10
Subtract 3s from both sides

Patrick is driving form Sydney to Canberra. He travels for 288km trip in 4 hours. What's his average speed?
Answer:
v = 72 km/h
Step-by-step explanation:
Given that,
The distance covered by the Patrick, d = 288 km
Time taken, t = 4 hours
We need to find the average speed of Patrick. We know that the average speed of an object is equal to the total distance covered divided by total time taken. Let it is v. So,
[tex]v=\dfrac{d}{t}\\\\v=\dfrac{288\ km}{4\ h}\\\\v=72\ km/h[/tex]
So, his average speed is equal to 72 km/h.
Solve for b.
