Given:
The diameter of the wheel is 2 feet.
Number of revolution = 100
To find:
The total distance covered by the bicycle.
Solution:
The circumference of a circle is:
[tex]C=2\pi r[/tex]
Where, r is the radius of the circle.
The diameter of the wheel is 2 feet. So, the radius of the circle is 1 feet.
Putting [tex]\pi =3.14, r=1[/tex] in the above formula, we get
[tex]C=2(3.14)(1)[/tex]
[tex]C=6.28[/tex]
It means the distance covered by the wheel in one revolution is 6.28 feet.
Number of revolution is 100. So, the total distance covered by the wheel in 100 revolution is:
[tex]6.28\times 100=628[/tex]
The total distance covered by the bicycle in 100 revolution is 628 feet.
Therefore, the correct option is B.

A student has taken three math tests so far this semester. His scores for the first three tests were 71, 75, and 79. Part A: Suppose his test scores continue to improve at the same rate. What will be the grade on the sixth and (final) test?
Answer:
The grade of this sixth and (final) test would be 91.
Step-by-step explanation:
This is an arithmetic series since each time the data is increasing by the common difference of 4, and we already know a₁ which is the first term in the sequence is 71, therefore we can say:
a₁ = 71
r = 4
a₆ = the sixth term that needs to be found out
n = 6
Formula of an arithemetic series:
aₙ = a₁ + r(n - 1)
a₆ = 71 + 4(6 - 1)
a₆ = 71 + 4(5)
a₆ = 71 + 20
a₆ = 91
Hence, the grade of this sixth and (final) test would be 91.
Hope this helps!

Answer:
158
Step-by-step explanation:
you only need to do is subtract
Jerry can do the job in approx 17 minutes working alone.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, Tom can do a job in 210 minutes and assuming Jerry to do the job
in x minutes and work to be 1.
∴ 1/210 + 1/x = 1/52.
1/x = 1/52 - 1/210.
1/x = (210 - 52)/2730.
1/x = 158/2730.
1/x = 79/1365.
x = 1375/79.
x = 17 minutes approx.

Find the distance d. Round your answer to the nearest tenth. Show all your work. Thanksss!
Answer: the distance for d is about 5.8 units
Step-by-step explanation:
Use the pythagorean theorem. a^2 + b^2+= c^2 . in this case, c^2 is the distance for d.
5^2 + 3^2= d^2
25+9= d^2
34= d^2

A ladder which is 6.7 m long is placed on the ground 2.8 m from a vertical wall and then leaned over to the wall. How high up the wall can the ladder reach? Give your answer rounded to 1 DP.
Answer:
6.1 m
Step-by-step explanation:
Always draw a diagram! And now pythagorean theorem. a^2 + b^2 = c^2
Substitution:
a^2 + 2.8^2 = 6.7^2
a^2 + 7.84 = 44.89
a^2 = 37.05
a = 6.086...
Rounding up to one decimal point, thats 6.1 m
What is the common ratio of the geometric sequence below? 18, -6, 2, -2/3
Answer:
Step-by-step explanation:
Common ratios are found by either multiplying the same number in to get to the next number in the sequence, or by dividing out the same number in to go the next number in the sequence. Multiply or divide, NOT add or subtract! Be careful! Obiviously, our numbers are going down, so we are dividing out a specific number as opposed to multiplying one in. To get from 18 to 6, we have to divide by 3; however, the 6 is negative, so we have to divide by -3. To determine if we are correct, divide -6 by -3 and see if that result is the next one in line. -6 divided by -3 is 2. So we are correct, and the common ratio is -3.
