Circle M dilated by a scale factor of 3 gives circle N. If the circumference of circle N is 6 cm, what is the circumference of circle M?
A.
54 cm
B.
3 cm
C.
2 cm
D.
18 cm
Step-by-step explanation:
2 cm
scale factor of 3
then 6/3 = 2 cm
Answer:
C. 2 cm
Step-by-step explanation:
As the circumference is a measure of length (one dimension), we can simply divide the given circumference of circle N by the scale factor to find the circumference of circle M:
⇒ circumference of circle M = circumference of circle N ÷ scale factor
= 6 cm ÷ 3
= 2 cm
(If we were working with area, we would have to divide/multiply by the square of the scale factor, since we would be working in 2 dimensions)

Gianna works in a department store selling clothing. She makes a guaranteed salary of $500 per week, but is paid a commision on top of her base salary equal to 15% of her total sales for the week. How much would Gianna make in a week in which she made $975 in sales? How much would Gianna make in a week if she made xx dollars in sales?
Earnings when selling $975:
Earnings when selling $x:
Answer:
$646.25 is her earnings when selling $975.
Her earnings when selling $x is 500 + 0.15x.
Step-by-step explanation:
You know that her guaranteed salary is $500, and she also gets a commission that is 15% of her sales. So, the expression is
500 + 0.15x
Where x is total sales. When you are given $975 as her total sales, plug it in for x:
500 + 0.15(975)
500 + 146.25
$646.25 is her earnings when selling $975.
Her earnings when selling $x is 500 + 0.15x.

True or false: The range is calculated by adding the highest and lowest scores in a data set and then dividing by the number of scores in the dataset.
Answer:
False
Step-by-step explanation:
You calculate range by first putting all the numbers in order. Then subtract the lowest number from the highest.
What the question is thats how to calculate the median.
Have a wonderful day!
From the definition of the range, we understood that the given statement is false.
The given statement is "The range is calculated by adding the highest and lowest scores in a data set and then dividing by the number of scores in the dataset".
We need to state whether the given statement is true or false.
What is the range?The range formula is mostly used in statistics to determine the range given in a particular data set. The formula helps in determining the centre of the set by finding the difference between the lowest and the highest number. In distribution, the large range means higher variability whereas the small range means low variability. The range formula includes the other aspects of statistics such as mean, median, and mode. Hence, the formula to calculate the range is:
R = Highest Value (H) - Lowest Value (L).
Therefore, from the definition of the range, we understood that the given statement is false.

Given the following exponential function, identify whether the change represents
growth or decay, and determine the percentage rate of increase or decrease.
Y= 30(1.003)^x
For the given exponential function, the change represents a growth and the percentage rate is 0.3%.
Exponential FunctionThe formula for the exponential function is:
[tex]y(t)=y(0)*(1+R)^t[/tex], where:
y(t)= final value
yo=initial value
R=rate
t= time
When 1+R > 1, the equation represents growth, while 1+R < 1 the equation represents decay.
The question gives: [tex]y=30*(1.003)^x[/tex].
When you compare [tex]y=30*(1.003)^x[/tex]with [tex]y(t)=y(0)*(1+R)^t[/tex], it is possible to see:
1. 1+R=1.003, so >1 . Therefore, the change represents growth.
2. 1+R=1.003 , therefore,
1.003=1+R
R=1.003-1
R=0.003
then,
%R=0.003*100=0.3%

For every 3 tickets you sell, your friend sells 4. You sell a total of 12 tickets. How many does your friend sell? Complete the ratio table to solve the problem.
Step-by-step explanation:
Total tickets I sell =12
For every 3 tickets I sell, my friend sells 1 more.
I sell 12/3 (=4)sets of 3 tickets.
So, my friend sells 12 +4 (=16)tickets.

The circumference of a circle whose radius is 11.5 inches.
Thus, option (a) is correct.
Given:
Diameter = 23 inch
So, Radius of circle = diameter/2
=23/2
= 11.5 inch
Now, the formula for circumference of a circle is
= 2πr
Substituting the value of r= 11.5 into the formula as
= 2 x 3.14 x 11.5
= 72.22 inches
Thus, the circumference of circle is 72.22 inches.

2. During typhoon Ambo, PAGASA tracks the amount of accumulating rainfall. For
<en place.
the first three hours of typhoon, the rain fell at a constant rate of 25mm per hour.
The typhoon slows down for an hour and started again at a constant rate of 20 mm
per hour for the next two hours. Write a piecewise function that models the amount
of rainfall as function of time.
Answer:
The piecewise equation is given as :[tex]A(t)=\begin{cases} 25x& \text{ if } 0 \leq x \leq 3 \\ 75& \text{ if } 3<x<4 \\ 75+20(x-4) & \text{ if } 4 \leq x \leq 6\end{cases}[/tex]
Step-by-step explanation:
Let x be the time in hour and A(x) be the amount of accumulating rainfall at time x.
We are given that in the first three hours the rain fell at a constant rate of 25mm per hour
Amount of rainfall in 1 hour = 25
Amount of rainfall in t hours = 25x
[tex]A(x) = 25x ; 0 \leq x \leq 3[/tex]
The rain then slows down and remains constant
So, Amount of rain for that hour = [tex]25 \times 3 = 75 mm[/tex]
75 mm ; 3
Now we are given that started again at a constant rate of 20 mm per hour for the next two hours.
Amount of rain after 4 hours = [tex]75+20(x-4) ; 4 \leq x\leq 6[/tex]
The rain increases at a rate of 20t from 4 ≤ x ≤ 6.
Hence the piecewise equation is given as :[tex]A(t)=\begin{cases} 25x& \text{ if } 0 \leq x \leq 3 \\ 75& \text{ if } 3<x<4 \\ 75+20(x-4) & \text{ if } 4 \leq x \leq 6\end{cases}[/tex]

Choose the missing step in the given solution to the inequality −6x − 10 > 14 + 2x. (1 point)

_______________
-8x>24
x 14
B.) -8x -10 >14
C.)−4x − 10 < 14
D.) −8x − 10 < 14
Answer:
- 8x > 24
Step-by-step explanation:
Given
- 6x - 10 > 14 + 2x ( subtract 2x from both sides )
- 8x - 10 > 14 ( add 14 to both sides )
- 8x > 24 ← required missing step
Divide both sides by - 8, reversing the symbol as a result of dividing by a negative quantity.
x < - 3 ← is the solution
Divide.
