Answer:
B) 60%
Step-by-step explanation:
Percentage formula
\(\sf Percentage=\left(\dfrac{Value}{Total\:value}\right) \times 100\)
To find what percent of 200 is 120, substitute the values into the percentage formula:
\(\begin{aligned}\implies \sf Percentage & = \dfrac{120}{200} \times 100\\\\&=\dfrac{120 \times 100}{200}\\\\&=\dfrac{12000}{200}\\\\&=\dfrac{120}{2}\\\\&=60\%\end{aligned}\)
Therefore, 120 is 60% of 200.

Complete the table. At the beginning of the summer, there are 15 rabbits living in a field. Each week for the rest of the summer, another rabbit moves in. The equation r=25 + w describes the number of rabbits, r, after a certain number of weeks, w
Weeks Since Summer Started Rabbits

_ 21

(image displayed below)
Based on the above, there are 26 rabbits after 1 week.
There are 33 rabbits after 8 weeks.
What is the numbers of Rabbits?Weeks Since Summer Started Rabbits
1 | 16
2 | 17
3 | 18
4 | 19
5 | 20
6 | 21
7 | 22
8 | 23
To find the number of rabbits after a certain number of weeks, we can substitute the number of weeks into the equation r = 25 + w and solve for r.
For example, after 1 week, we have:
r = 25 + w = 25 + 1 = 26
So there are 26 rabbits after 1 week.
Similarly, after 8 weeks:
r = 25 + w = 25 + 8 = 33
So there are 33 rabbits after 8 weeks.

The best measure of variability for the data is standard deviation and player B is more consistent with IQR of 1.5
What is Standard Deviation?The standard deviation refers to a measurement of the data dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.
Standard Deviation is calculated by
Each number's deviation from the mean must be determined, and then squared.
Next, add up all of these values.
Divide the result by the quantity of numbers.
Then calculate its square root.

A movie-theater employee notes an inverse relationship between the theater's popcorn sales and its nacho sales. On a given night, the theater makes $1,512 from popcorn sales and $1,584 from nacho sales. If on the next night the employees sell $1,848 of popcorn, how much is earned from nachos?
Answer:
Using proportions, it is found that $1,225 is earned from nachos.
This question is solved by proportions, using a rule of three.
The measures have an inverse relationship, hence line multiplication is applied instead of cross multiplication.
When the theater makes $1,540 from popcorn sales, it makes $1,330 from nacho sales. How much is earned from nachos when $1,672 is earned from popcorn?
The rule of three is:
$1,540 - $1,330
$1,672 - $x
Applying line multiplication:
$1,225 is earned from nachos.
how to check : 3x+5=11
Answer:
There are two ways to check if 3x+5=11 is true:
Subtract 5 from both sides of the equation. This will isolate x on the left-hand side of the equation.
3x = 6
Divide both sides of the equation by 3. This will divide both sides of the equation by 3, which will cancel out the 3 on the left-hand side of the equation, leaving x by itself.
x = 2
You can also check if 3x+5=11 is true by plugging in 2 for x. If you do this, you will get 3(2)+5 = 6+5 = 11. Therefore, 3x+5=11 is true when x=2.

Carter wants to ride his bicycle 28.7 miles this week. He has already ridden 17 miles. If he rides for 3 more days, write and solve an equation which can be used to determine mm, the average number of miles he would have to ride each day to meet his goal.
Answer: Carter will have to ride 3.9 miles on his bicycle every day in order to achieve his goal.
Step-by-step explanation:
Finding the answer to this problem isn't too complicated, and all we have to do is make and solve an equation. First, we know how many miles Carter wants to ride his bicycle (this is what our equation will be equal to), and how many miles he's completed already (we add that to how many he has to do daily). We also know how many days he has left to complete this goal (multiply the number he has to do daily by three).
All we have to do now is construct a basic equation:
17 + 3x = 28.7
Let's move the 17 over to the other side of the equation. To do that, subtract 17 from both sides.
3x = 28.7 - 17
3x = 11.7
This gives us the amount of miles Carter still has to ride - in total. To find out how many miles he has to ride daily, we just divide 3 from both sides.
3x/3 = 11.7/3
x = 3.9 (miles - don't forget the units!)
Carter will have to ride 3.9 miles on his bicycle every day in order to achieve his goal. Hope this helps!

5 out of the 12 issues it publishes each year. Write and solve a proportion
to determine how many times a photo of a main dish will be on the front
cover during the next 5 years.
Answer:
Step-by-step explanation:
Based on the number of times the photo appears per year, in 5 years it will appear 25 times.
Every year, the photo in question appears 5 out of 12 times.
If there were 5 years therefore, it would appear:
= Number of times per year x Number of years
= 5 x 5
= 25 times

The correct option is C .
Given, steps to solve kx + 3x = 4 .
To solve for x, isolate x in the equation .
Equation : kx + 3x = 4
Take x common in the LHS of equation.
x(k+3) = 4
Divide LHS and RHS of the equation by x+3
\(\frac{x(x+3)}{x+3} = \frac{4}{x+3}\)
\(x = \frac{4}{x+3}\)

A gym charges membership dues of $25 per month. Which equation represents the total cost, C, of belonging to the gym for m months?
A. C = 25 ÷ m
B. C = 25m
C. C = m + 25
D. C = m – 25
Answer:
The answer is B.
Step-by-step explanation:
Given that the fixes amount is $25 per month. In order to find the total cost, C, you have to multiply $25 with the number of months.
C = 25m
C = 25m, is the required equation that represents the total cost, C, of belonging to the gym for m months. Option B is correct.
Given that,
A gym charges membership dues of $25 per month.
It is to be determined which equation represents the total cost, C, of belonging to the gym for m months.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
Here,
Let the total charge for m month be x.
A gym charges membership dues of $25 per month.
For m number of the month total cost = 25m
or
C = 25m
Thus, C = 25m, is the required equation that represents the total cost, C, of belonging to the gym for m months. Option B is correct.

j + 17/4 = 7
HELP QUICK
Answer:
J = 11/4
Step-by-step explanation:
J + 17/4 = 7
7 as a fraction
7 x 4 = 28
28/4
J + 17/4 = 28/4
J + (17/4 - 17/4) = (28/4 - 17/4)
J = 11/4
Answer:
j = 11/4
Step-by-step explanation:
For quick answer just in your head multiply 4 by 7, which is 28. Then subtract 17 since that’s the given, which you will get 11. So j = 11/4. Hope this somewhat makes sense.
To solve for the value of j, we need to isolate j on one side of the equation.
First, we can simplify the left side of the equation by multiplying both sides by 4 to get rid of the fraction:
j + 17/4 = 74(j + 17/4) = 4(7)
4j + 17 = 28
Next, we can isolate j by subtracting 17 from both sides:
4j + 17 - 17 = 28 - 174
j = 11Finally, we can solve for j by dividing both sides by 4:
j = 11/4
Therefore, the value of j that satisfies the equation is j = 11/4.
we can check whether j = 11/4 is the correct solution by substituting it into the original equation and seeing if it is true.
j + 17/4 = 7
When we substitute j = 11/4, we get:
(11/4) + 17/4 = 7
Simplifying the left side of the equation, we get:
28/4 = 7
Both sides of the equation simplify to 7, which means that the solution j = 11/4 is correct.
To further verify, we can also add 11/4 and 17/4 to get:
11/4 + 17/4 = 28/4 = 7
Since we obtained the same value for both sides of the equation, we can conclude that the solution j = 11/4 is correct.
