Dustin has a spinner that is divided into 5 equal-size sections colored pink, blue, orange, white, and green. What is the probability that Dustin spins pink on the 1st spin and then spins a color other than pink on the 2nd spin?
Answers
Answer:
1/6
Step-by-step explanation:
1st spin:
1 out of the 5 sections are pink, so the probability of spinning a pink on the 1st spin is 1/5.
2nd spin:
5 out of the 6 sections are not pink, so the probability of spinning a pink on the 2nd is 5/6.
Multiply the probabilities of the two spins to get the answer.

Ms. Masi is going to be paid $11.25 per day to look after Ms. Simms’ dog. She wants to save all of her earnings, but she owes her brother $72. After the first day of dogsitting, Ms. Masi uses her earnings to pay part of her debt to her brother. After the second day, she uses her earnings to pay more of her debt. Ms. Masi plans to save every dollar of her dog sitting money as soon as she has paid her brother in full.
How many days will it take for Ms. Masi to pay her brother in full? Explain.
Answers
Answer:
7 days
Step-by-step explanation:
So! Ms. Masi earns $11.25 everyday, and is paying her brother back everyday. Let's make an equation to solve for the number of days!
11.25d = 72 (d = # of days)
Now, we have to solve this equation to see how many days (d) it will take Ms. Masi to pay her brother back.
11.25d = 72
÷11.25 ÷11.25 (Divide by "11.25" to get the variable by itself)
d = 6.4
Since, she only gets 1 pay per day, Ms. Masi will have to wait til her 7th day to pay her brother back.
Hope this Helps! :)

Under her cell phone plan, Nicole pays a flat cost of $35 per month and $5 per gigabyte. She wants to keep her bill under $60 per month. Use the drop-down menu below to write an inequality representing gg, the number of gigabytes she can use while staying within her budget.
Answers
Answer:
< 5 gigabytes
Step-by-step explanation:
Let the number of gigabytes be represented as: g
Under her cell phone plan, Nicole pays a flat cost of $35 per month and $5 per gigabyte. She wants to keep her bill under $60 per month.
Under $60 = less than (<) $60
Hence, our inequality equation is given as:
$35 + $5 × g < 60
35 + 5g < 60
Collect like terms
5g < 60 - 35
5g < 25
g < 25/5
g < 5 gigabytes
Therefore, the number of gigabytes she can use while staying within her budget less than 5 gigabytes

You can transform ⨀T to ⨀T' by translating it and then performing a dilation centered at T'. Find the translation rule and the scale factor of the dilation.
Simplify the scale factor and write it as a proper fraction, improper fraction, or whole number.
Translation: (x,y)↦ (___ ) , (____)
,
Scale factor:
Answers
Answer:
(x,y)↦ ( x + 1 ) , ( y + 9 )
scale factor 2
Step-by-step explanation:
Step 1 identify the translation.
To do this we find the center of ⨀T and the center of ⨀T' and find the difference between their x and y values.
The center of ⨀T is at ( -1 , -7 )
The center of ⨀T' is at ( 0 , 2 )
we now find the difference between the x and y values. ( note that you must subtract the x and y values from the preimage from the translated image to get the correct translation. )
For the x values: 0 - ( - 1 ) = + 1
For the y values: 2 - ( -7 ) = + 9
So translation was (x,y)↦ ( x + 1 ) , ( y + 9 )
step 2 Find the scale factor
We can identify the scale factor by dividing the radius of the preimage by the radius of the dilated image.
The radius can be identified by finding the distance between the center and any point on the circle
The radius of the preimage is 3
The radius of the dilated image is 6
So scale factor = 6 / 3 or 2

Find the area of the shaded region
8cm
Answers
After answering the query, we may state that area of shaded region = 100.48-64 = 36.48 sq cm.
What is circle?Each point in the plane that is a certain distance from the centre (another point) forms a circle. Thus, it is a curve composed of points whose are separated from another point in the plane by a certain distance. Additionally, at every angle, it is alternately symmetric about the centre. The closed, two-dimensional plane of a circle has every pair of points equally separated from the "centre." By drawing a line through the circle, one may create a line of circular symmetry. Additionally, at every angle, it is rotationally equal about the Centre.
here, by Pythagoras theorem
diagonal = [tex]\sqrt(8^2 + 8^2) = \sqrt(64+64) = \sqrt(128) = 8\sqrt2[/tex]
radius = [tex]4\sqrt2[/tex]
area of circles = [tex]\pi r^2 = 3.14 * (4\sqrt2)^2 = 100.48 cm^2[/tex]
area of square = 8*8 = 64 sq cm
area of shaded region = 100.48-64 = 36.48 sq cm.

What is the rate of change of the linear function that has a graph that passes through (9,2) and (3,-1)?
Answers
=================================================
Explanation:
Your teacher wants you to find the slope
m = slope
m = (y2-y1)/(x2-x1)
m = (-1-2)/(3-9)
m = -3/(-6)
m = 1/2
----------------
Extra info:
We can think of the slope as
slope = rise/run
and furthermore,
rise = change in y = y2-y1run = change in x = x2-x1Essentially we subtract the corresponding y coordinates together, subtract the x together (in the same order as the y values), then divide the differences.

Answers
Answer:
x = -44/13
y = -65/13
Step-by-step explanation:
Using matrix form means using the crammers rule
The matrix form of the expression is written as;
[tex]\left[\begin{array}{ccc}8&5\\-1&1\\\end{array}\right] \left[\begin{array}{ccc}x\\y\\\end{array}\right] = \left[\begin{array}{ccc}9\\7\\\end{array}\right][/tex]
AX = B
taking the determinant of A;
|A| = 8(1) - 5(-1)
|A| = 8 + 5
|A| = 13
After replacing the first row with the column matrix;
[tex]A_x =\left[\begin{array}{ccc}9&5\\7&-1\\\end{array}\right][/tex]
|Ax| = 9(-1)-5(7)
||Ax| = -9 - 35
|Ax| = -44
x = |Ax|/|A|
x = -44/13
similarly for y
[tex]A_x =\left[\begin{array}{ccc}8&9\\-1&7\\\end{array}\right][/tex]
|Ay| = 8(7)+9
|Ay| = 56+9
|Ay| = 65
y = |Ay|/|A|
y = -65/13
