the length of an arc is 10cm find angle subtended by arc if the circumference of the circle of which the arc form part 60cm
9514 1404 393
Answer:
60° = π/3 radians
Step-by-step explanation:
The 10 cm length of the arc is 1/6 of the 60 cm length of the circumference of the circle. That means the angle measure of the arc is 1/6 of the total angle measure of a circle.
arc = 360°/6 = 60°
arc = (2π radians)/6 = π/3 radians
Ike notices an interesting pattern; he sees that 7 is 14% of a and 18 is 6% of b. If c is b/a, then what is the value of c?
Answer: c = 6
Step-by-step explanation:
%/100 = is/of
14/100 = 7/a. (14% of what number is 7) (cross multiplication)
(7*100)/14 = 50 (a)
6/100 = 18/b
(18*100)/6 = 300 (b)
b/a = 300/50 = 6
Pattern is a rule that guides the formation of a dataset. Based on the given patterns of a and b, the value of c is 6
Given that:
[tex]7 = 14\% \times a[/tex]
[tex]18 = 6\% \times b[/tex]
Make a the subject in [tex]7 = 14\% \times a[/tex]
[tex]a=7 \div 14\%[/tex]
[tex]a = 50[/tex]
Make b the subject in [tex]18 = 6\% \times b[/tex]
[tex]b = 18 \div 6\%[/tex]
[tex]b = 300[/tex]
Given that:
[tex]c = \frac ba[/tex]
Substitute values for a and b
[tex]c = \frac{300}{50}[/tex]
[tex]c = 6[/tex]
Hence, the value of c is 6

-3/4(8n+12)=3(n-3) show work pls
Answer: n = 0
Step-by-step explanation:
Given expression
(-3/4) (8n + 12) = 3 (n - 3)
Expand parentheses and apply the distributive property
-6n - 9 = 3n - 9
Add 9 on both sides
-6n - 9 + 9 = 3n - 9 + 9
-6n = 3n
Subtract 3n on both sides
-6n - 3n = 3n - 3n
-9n = 0
Divide -9 on both sides
-9n / -9 = 0 / -9
[tex]\boxed{n=0}[/tex]

Albums are on sale for $8 exch and you have a gift card worth $100. Write
an expression for the amount of money left on the gift card after
purchasing n albums. Evaluate the expression to find the amount of
money left after purchasing 6 albums.
Answer:
(100 - 8n) is our equation, with 100 being the gift card balance, 8 being the cost of each album, and n being the number of albums.
When n = 6, the equation equals 52. This means that you have $52 left after purchasing 6 albums.

How do I do this? I need help really bad. Can someone help me with this question?
Answer:
Step-by-step explanation:
It seems like there is only one question. I'll answer that first and then we'll discuss what might be inferred from the introduction.
1)
The way the problem is set up you get a factoring to take place
(x^3 - 8) = (x - 2)(x^2 + 2x + 4)
================
(x - 2)
This question is unique. They expect you to cancel, which leaves you with y = x^2 + 2x + 4) which is a quadratic.
The reason you don't put in x = 2 is because technically, you get 0/0 which can be shown to be either 1 or 0. To get out of that, we say that 0/0 is undefined. The graphing program has taken the stance that 0/0 is 1. However I wouldn't really accept that. The whole problem comes down to 0/0 which is undefined.
A. f(x) = l-2xl - 3
Domain: {1, 2, 3}
Find the range
Hello there!
We are given the function:
[tex] \displaystyle \large{ f(x) = | - 2x| - 3} \\ [/tex]
To find the range, we know that domain is the set of all x-values and also called 'input' while range is the set of all y-values and also called 'output'.
Basic Function - you add the input, you get the output. You add x-value in a function, you get y-value. You add domain, you get range.
So, we substitute x = 1,2 and 3 in the function.
x = 1
[tex] \displaystyle \large{ f(1) = | - 2(1)| - 3} \\ \displaystyle \large{ f(1) = | - 2| - 3} \\ [/tex]
Recall that any numbers in absolute value are always positive.
[tex] \displaystyle \large{ f(1) = 2 - 3} \\ \displaystyle \large{ f(1) = - 1} \\ [/tex]
x = 2
[tex] \displaystyle \large{ f(2) = | - 2(2)| - 3} \\ \displaystyle \large{ f(2) = | - 4 | - 3} \\ \displaystyle \large{ f(2) = 4 - 3} \\ \displaystyle \large{ f(2) = 1}[/tex]
x = 3
[tex] \displaystyle \large{ f(3) = | - 2(3)| - 3} \\ \displaystyle \large{ f(3) = | - 6| - 3} \\ \displaystyle \large{ f(3) = 6 - 3} \\ \displaystyle \large{ f(3) = 3}[/tex]
Therefore, Range: {-1,1,3}

2. SALES TAX Suppose that a state sales tax is 7%. Make a table showing the
amount of tax on items with prices of $6, $8, $10, and $12. How can you
find whether the price and amount of sales tax are linearly related?
Answer:
$6 * .07= 0.42 tax
6+042= $6.42
$8*.07=0.56 tax
8+.56= $8.56
$10*.07=0.70 tax
10+0.70=$10.70
$12*.07=0.84 tax
12 + 0.84=$12.84
Jake says that
3/5 - 1/2 = 2/3
which is incorrect. What is his mistake
It appears Jake said 5-2 = 3 for the denominator portions. This is not correct. In order to subtract fractions, the denominators must be the same and they stay the same the entire time. Only the numerators (aka stuff up top) are being subtracted.
Currently 3/5 - 1/2 cannot be subtracted since the 5 and 2 are different denominators. But we can say this:
3/5 = 6/10
1/2 = 5/10
and then from there, we can say:
3/5 - 1/2 = 6/10 - 5/10 = (6-5)/10 = 1/10
So in short,
3/5 - 1/2 = 1/10

The base fare per ride on the MTA bus or subway is $2.75, but you get a 5% discount with a purchase. A weekly unlimited MetroCard costs $32.00. How many rides a week will make the weekly unlimited pass more cost-effective?
"13" or "more than 13" rides will make the weekly unlimited pass more cost effective. A further solution is provided below.
The given values are:
Base fare per ride = $2.75Discount = 5%Weekly unlimited Metro Card costs = $32The Fare after discount will be:
= [tex]2.75\times \frac{100-5}{100}[/tex]
= [tex]2.75\times \frac{95}{100}[/tex]
= [tex]2.75\times 0.95[/tex]

hence,
In $32, the minimum number of rides will be:

. Find the sum of the first 20 terms of the
arithmetic sequence 27, 22, 17, ....
Answer:
Step-by-step explanation:
a = 27
n = 20
d = -5
L20 = 27 + (n - 1)*d
L20 = 27 + (20-1)*_5
L20 = 27 + 19*-5
L20 = -68
Sum = (a + L)*n/2
Sum = (27 - 68)*20/2
Sum = -41 * 10
Sum = - 410

Answer:
30+(2x+7)+63=180(sum of angles of triangle )
30+2x+7+63=180
2x+100=180
2x=180-100
x=80/2
x=40
Answer:
[tex]\boxed {\boxed {\sf (2x+7)+30+63= 180}}[/tex]
[tex]\boxed {\boxed {\sf x=40}}[/tex]
Step-by-step explanation:
We are asked to write an equation to solve for x and use the equation to find x.
We know that the angles in a triangle must add to 180 degrees. Therefore, the sum of the three angles in this triangle: 30, 63, and (2x+7) must equal 180. We can set up an equation.
[tex](2x+7)+ 30 +63= 180[/tex]
Now we can use the equation to solve for x. First, we combine like terms on the left side of the equation. The 3 terms without variables or constants can be added.
[tex]2x+ (7+30+63)= 180[/tex]
[tex]2x+ (100)= 180[/tex]
We are solving for x, so we must isolate the variable. 100 is being added to 2x. The inverse operation of addition is subtraction. Subtract 100 from both sides of the equation.
[tex]2x+100-100= 180-100 \\2x=180 -100 \\2x=80[/tex]
x is being multiplied by 2. The inverse operation of multiplication is division. Divide both sides of the equation by 2.
[tex]\frac {2x}{2}= \frac{80}{2}[/tex]
[tex]x= \frac {80}{2} \ \\[/tex]
[tex]x=40[/tex]
The equation is (2x+7)+ 30+63= 180 and x is equal to 40.
