b. 35.6 inches
C. 37.5 inches
d. 39.3 inches
This question is incomplete
Complete Question
If the measurement of a central angle is 5pi/6, find the length of its intercepted arc in a circle with a radius of 15 inches
a 33.4 inches
b. 35.6 inches
C. 37.5 inches
d. 39.3 inches
Answer:
d. 39.3 inches
Step-by-step explanation:
We are to find the Arc length of the circle
To solve the above question, the formula is given as:
Arc length = Central angle × radius
From the above Question, we are given:
Central angle = 5pi/6 = 5π/6
Radius = 15 inches
Hence,
Arc length = 5π/6 × 15 inches
Arc length = 235.61944901923448/ 6
Arc length = 39.26990817 inches
Approximately , the Arc length
= 39.3 inches.
Therefore, Option d is the correct answer.
What are the coordinates of point S"? (negative three-halves, nine-halves) (negative nine-halves, fifteen-halves) (nine-halves, negative three-halves) (negative fifteen-halves, 0)
Answer:
[tex]S=(\frac{9}{2},-\frac{3}{2})[/tex]
Step-by-step explanation:
The missing details are:
[tex]T= (0,4)[/tex]
[tex]M = (\frac{9}{4}, \frac{5}{4})[/tex] --- Midpoint of ST
Required
Determine the coordinates of S
To do this, we apply the mid-point formula:
[tex]M(x,y) = \frac{1}{2}(x_1+x_2,y_1+y_2)[/tex]
Where
[tex]M(x,y) = (\frac{9}{4}, \frac{5}{4})[/tex]
[tex]T(x_1,y_1) - (0,4)[/tex]
The equation becomes:
[tex]M(x,y) = \frac{1}{2}(x_1+x_2,y_1+y_2)[/tex]
[tex](\frac{9}{4},\frac{5}{4}) = \frac{1}{2}(0+x_2,4+y_2)[/tex]
[tex](\frac{9}{4},\frac{5}{4}) = \frac{1}{2}(x_2,4+y_2)[/tex]
Multiply through by 2
[tex]2*(\frac{9}{4},\frac{5}{4}) = 2*\frac{1}{2}(x_2,4+y_2)[/tex]
[tex](\frac{9}{2},\frac{5}{2}) = (x_2,4+y_2)[/tex]
By comparison:
[tex]x_2 = \frac{9}{2}[/tex]
[tex]4 + y_2 =\frac{5}{2}[/tex]
[tex]y_2 =\frac{5}{2}-4[/tex]
[tex]y_2 =\frac{5-8}{2}[/tex]
[tex]y_2 =-\frac{3}{2}[/tex]
Hence, the coordinates of S is:
[tex]S=(\frac{9}{2},-\frac{3}{2})[/tex]

Step-by-step explanation:
3. (1, 2) (2, 4)
(4 - 2)/(2 - 1)= 2/1 = 2
4. (5, 2) (10, 4)
(4 - 2)/(10 - 5) = 2/5
5. (4, 1) (8, 2)
(2 - 1)/(8 - 4) = 1/4
6. (0, 0) (1, 20)

Bryan has quarters and nickels in his piggy bank. He has three times as many nickels as he has quarters. If the total value of the coins is $12, find the number of nickels in the piggy bank.
Answer:
90
Step-by-step explanation:
Quarters , q = 25 cent
Nickel, n = 5 cent
3 times as many nickels as quarters;
n = 3q
Total value of coins = $12
n + q = $12
0.05n + 0.25q = 12
0.05(3q) + 0.25q = 12
0.15q + 0.25q = 12
0.40q = 12
q = 12 / 0.40
q = 30
n = 3q
n = 3(30)
n = 90
90 nickels

Which ratio represents the cotangent of angle B in the right triangle below?
A. 5/3
B. 3/5
C. 3/4
D. 4/3
Answer:
C. 3/4
Step-by-step explanation:
Using the SOH CAH TOA identity;
tan theta = opposite/adjacent
From the diagram
Opposite = x
Adjacent = 12
tan <B = x/12
Since cot <B = 1/tan <B
cot <B = 12/x
Get x using pythagoras theorem
x² = 20²-12²
x² = 400 -144
x² = 256
x = 16
Hence cot <B = 12/16
cot <B =3/4
Work out the value of x
Answer:
a=21
b=70

A chess club with 45 members is electing a new president. Bob received 18 votes. What percentage of the club members voted for Bob?
Given:
A chess club with 45 members is electing a new president.
Bob received 18 votes.
To find:
The percentage of the club members who voted for Bob.
Solution:
We have,
Total number of members = 45
Votes received by bob = 18
Now, the percentage of the club members who voted for Bob is
[tex]\%=\dfrac{\text{Number of members voted for bob}}{\text{Total members}}\times 100[/tex]
[tex]\%=\dfrac{18}{45}\times 100[/tex]
[tex]\%=\dfrac{2}{5}\times 100[/tex]
[tex]\%=\dfrac{200}{5}[/tex]
[tex]\%=40[/tex]
Therefore, 40% of the club members voted for Bob.

Hey! I'm confused on this question It's : 3/4 - 3/10
Answer:
9/20
Step-by-step explanation:
I hope this helps :)
Answer:
9/20
Step-by-step explanation:
In order to subtract fractions you need to find the least common denominator. Since the LCD is 20 (4 times 5 or 10 times 2) you need to multiply each fraction by 1 to get the denominators the same.
3/4 times 5/5 = 15/20
3/10 times 2/2 = 6/20
now you can subtract!
15/20 - 6/20 = 9/20
you can not simplify this, so your final answer is 9/20
