Answer:
Explanation:
There is a theorem in geometry that says:
In a circle, if two chords are equal in measure, then their corresponding minor arcs are equal in measure.
Those small tick marks on each of the chords means that they are equal in measure. So, following the theorem, the arcs are also equal in measure.
If they are equal and
arc AB = arc CB
arc AB = 24 feet
Then
arc CB = 24 feet
by substitution.

Answer:
1/3 ( 5y-2) = x
Step-by-step explanation:
5y = 3x+2
Subtract 2 from each side
5y -2 = 3x+2-2
5y-2 = 3x
Divide each side by 3
1/3 ( 5y-2) = 3x/3
1/3 ( 5y-2) = x

Hana made $126 for 7 hours of work.
At the same rate, how many hours would she have to work to make 216?
Answer:
12 hours
Step-by-step explanation:
126 dollars / 7 hours of work = 18 dollars per hour (Pretty neat honestly)
So she made 216 dollars / x = 18 dollars per hour
18x=216 (cross multiply)
216/18 = 12 hours of work
Answer: 12 hours
Step-by-step explanation:
It takes her 7 hours to make $126 dollars and we need to find out how many hours(a) to make $216
So this is the equation
7 hours= 126 dollars
a hours= 216 dollars
Cross multiply
126 x a = 7 x 216
126a = 1512
Divide both sides by 126
a= 12 hours

Which of the following is a proportion? 9/12= 8/10 3/4= 9/12 6/8= 8/12 12/18= 9/16
Answer:
It would be 3/4=9/12
Step-by-step explanation:
The proportion relationship of the given ratios is 3/4= 9/12 thus option (B) is correct.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
As per the given,
In the fractions, 3/4
Multiply by 3 on the numerator and denominator.
3/4 x 3/3 = 9/12
3/4 x constant = 9/12
Remove constant.
3/4 ∝ 9/12
Hence "The proportion relationship of the given ratios is 3/4= 9/12".

2(4s-16)-5s= -5 What is S?
Answer:
s=9
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
2*(4*s-16)-5*s-(-5)=0
Pull out like factors :
4s - 16 = 4 • (s - 4)
Pull out like factors :
3s - 27 = 3 • (s - 9)
3 • (s - 9) = 0
Solve : s-9 = 0
Add 9 to both sides of the equation :
s = 9

Find a fraction in between 21/34 and 34/55
Answer:
A fraction between that is 2311/3740
Step-by-step explanation:
This is because the denominator is simplified into one number and the fraction is taken from there.
2311/3740
Step-by-step explanation:34 = 2×17
55 = 5×11
LCM = 2×5×11×17 = 1870
⁵⁵⁾21/34 = ²⁾1155/1870 = 2310/3740
³⁴⁾34/55 = ²⁾1156/1870 = 2312/3740
2310/3740 < 2311/3740 < 2312/3740
I need someone to help me find the missing value please.
Answer:
7
Step-by-step explanation:
Note the relation between x and y
The values of y are 2 less than the corresponding values of x, that is
x = - 3 → y = - 3 - 2 = - 5
x = 0 → y = 0 - 2 = - 2
x = 1 → y = 1 - 2 = - 1
x = 5 → y = 5 - 2 = 3
Thus
x = 9 → y = 9 - 2 = 7 ← missing value
Solve the equation-3y = 21 using inverse operations. What is the inverse operation step? What is the solution?
Answer:
Y=-7
Step-by-step explanation:
The solution to the equation -3y = 21 is y = -7.
To solve the equation -3y = 21 using inverse operations, we want to isolate the variable y by performing the inverse operation.
Now, the inverse operation of multiplication by -3 is division by -3.
By dividing both sides of the equation by -3, we can isolate y.
Let's perform the inverse operation:
(-3y) / -3 = 21 / -3
y = -7
Therefore, the solution to the equation -3y = 21 is y = -7.

The number 11 is increased to 12. What is the percentage by which the number was increased, to the nearest tenth of a percent?
Answer:
9.1%
Step-by-step explanation:
You can find this answer by dividing 12 by 11. When you do that, you get that 12 is 109.1% percent of 11. 11 is obviously 100% of 11, so it increased by the difference of the two percentages, 109.1-100 = 9.1%

A cell phone company charges $4 per GB beyond
20GB in a month. The monthly plan is $59.99, and
the bill for January is $75.99. How many GB were
used in that month?
Answer:
25GB was used that month
Step-by-step explanation:
Here, we want to calculate the GB used for the month.
Since we have $59.99 for 20GB, then the extra that brought the bill to $75.99 must have been from the beyond charges.
The extra charges is thus $75.99 - $59.99 = $20
Now, since $4 is charged as extra and we have a total of $20, the number of extra GB is thus 20/4 = 5
So the total GB for that month is 20 + 5 = 25GB

The USDA reported that in 1990 each person in the United States consumed an average of 133 pounds of natural sweeteners. They also claim this amount has decreased by about 0.6 pounds each year. a. If 1990 could be considered year zero, which of the above numbers represents the slope and which represents the y intercept? b. What is the equation of the line of best fit using the slope and y-intercept above? c. Predict the average consumption of sweeteners per person for the year 2005.
Answer:
The problem implies that we want to write the (average) amount of natural sweeteners consumed per person as a function of time. Let y represent the (average) amount of natural sweeteners consumed per person (in pounds), and let x represent the time measured in years since 1990. That is, x = 0 represents 1990. If y is a linear function of x, then we can use the slope-intercept form y = mx + b (where m is the slope and b is the y-intercept) to write the function.
The slope can be interpreted as the rate of change of y with respect to x, which in this case means the change in consumption of natural sweeteners per year. The statement that consumption has decreased by 0.6 pounds per year tells us that the slope is m = -0.6 Also, the y-intercept is the same as the y-value of the function when x = 0. (In our case, that means time 0, that is, 1990.) Therefore the y-intercept is b = 133. Hope that helps! Let me know if you have any further questions.
