Answer:
$216
Step-by-step explanation:
Find how much Mary made per hour by dividing 144 by 8 to get 18. Then, multiply that number by 12 which $216
Answer:
$216
Step-by-step explanation:
First, find out what Mary makes every hour. To find this, we divide 144 by 8.
144/8 = $18
This means that Mary makes $18 per hour.
Now, we find out how much Mary would make if she worked for 12 hours:
x = # of hours worked
18n
18(12)
$216
Therefore, Mary would make $216 in 12 hours.

Urgent. There are 12 coloured counters in a bag. The counters are black, white or grey A counter is chosen at random. The probability that the counter is not black is 3/4. The probability that the counter is not white is 2/3. Work out the probability that the counter is grey.
Answer:
1/12
Step-by-step explanation:
Needed information
[tex]\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}[/tex]
The sum of the probabilities of all outcomes must equal 1
Solution
We are told that the probability that the counter is not black is 3/4.
As the sum of the probabilities of all outcomes must equal 1, we can work out the probability that the counter is black by subtracting 3/4 from 1:
[tex]\sf P(counter\:not\:black)=\dfrac34[/tex]
[tex]\implies \sf P(counter\:black)=1-\dfrac34=\dfrac14[/tex]
We are told that the probability that the counter is not white is 2/3.
As the sum of the probabilities of all outcomes must equal 1, we can work out the probability that the counter is white by subtracting 2/3 from 1:
[tex]\sf P(counter\:not\:white)=\dfrac23[/tex]
[tex]\implies \sf P(counter\:white)=1-\dfrac23=\dfrac13[/tex]
We are told that there are black, white and grey counters in the bag. We also know that the sum of the probabilities of all outcomes must equal 1. Therefore, we can work out the probability the counter is grey by subtracting the probability the counter is black and the probability the counter is white from 1:
[tex]\begin{aligned}\sf P(counter\:grey) & = \sf1-P(counter\:black)-P(counter\:white)\\\\ & =\sf 1-\dfrac14-\dfrac13\\\\ & = \sf \dfrac{12}{12}-\dfrac{3}{12}-\dfrac{4}{12}\\\\ & = \sf \dfrac{12-3-4}{12}\\\\ & = \sf \dfrac{5}{12}\end{aligned}[/tex]

The probability of a customer purchase popcorn at the movie theater is 0.3. What is the probability that a customer will not purchase popcorn
Reason:
There's a 30% chance they buy the popcorn, which means there's a 70% chance they don't buy it.
100% - 30% = 70%
Then convert the 70% to 0.7
Answer:
0.7 or 70%
Step-by-step explanation:
0.3 * 100 = 30%
100%-30% = 70%
You either buy or not. If 30% you don't then 70% you do.

Consider this dilation.
Hint: Remember the notation for the original figure and the figure after it has undergone transformation.
(a) Is the image of the dilation a reduction or an enlargement of the original figure? Explain.
(b) What is the scale factor? Explain and show your work.
Answer:
(a) Reduction
(b) scale factor = 1/2
Step-by-step explanation:
(a) A reduction is a dilation that creates a smaller image.
As A'B'C'D' is smaller than ABCD, image A'B'C'D' is a reduction of image ABCD.
(b) To find the scale factor:
find the center of dilation by connecting the corresponding points from the original and dilated image and finding where these lines intersect (see attached image)measure from the center of dilation to a point on the original image.measure from the center of dilation to the corresponding point on the dilated image.Divide the distance to the dilated image by the distance to the original image.center of dilation = (0, 0)
(0, 0) to point C = 4 units
(0, 0) to point C' = 2 units
⇒ scale factor = 2/4 = 1/2

The value of log subscript 6 baseline start fraction 1 over 36 end fraction is -2.
Let x is the unknown value
We have to determine the value of x
[tex]Log_6 ( 1/36) = x....Given[/tex]
What is the meaning of logarithmic function?Logarithmic functions are the inverses of exponential functions, and an exponential function can be expressed in logarithmic form.
[tex]( 1/36) = 36^{-1} = (6^{2})^{-1} = 6^{-1}[/tex]
[tex]Log_6( 1/36) = Log_6 6^{-2} = -2 Log_6 6[/tex]

Our answer has to be B because we need to develop an equation to solve for the value of each term in order to find the number pattern.
Step-by-step explanation:
This is a sequence problem.
You need to identify the relationships between the given number pattern.
If we look at -14 and -8, you can clearly see that something is happening.
If we were to do -14+6 that would equal to -8
Then we try the other one like -8 and -2. We can do -8 + 6 = -2
So our sequence/number pattern is that we're increasing by 6.
We could also develop an equation: -14 + x= -8
Our answer has to be B because we need to develop an equation to solve for the value of each term in order to find the number pattern.

What is the volume of a sphere with a radius of 46.1 ft, rounded to the nearest tenth
of a cubic foot?
Answer:
410176.90 ft³Step-by-step explanation:
Here, it is given that the radius of sphere is 46.1 ft and we have to find the volume of the sphere .
So, we know that,
⇒ Volume(Sphere) = 4/3πr³
We will take the value of π as 3.14Now, Substituting the given values in the formula :
⇒ Volume(Sphere) = 4/3 × 3.14 × (46.1)³
⇒ Volume(Sphere) = 4/3 × 3.14 × 97972.18
⇒ Volume(Sphere) = 4/3 × 307632.64
⇒ Volume(Sphere) = 307,632.64 × 4/3
⇒ Volume(Sphere) = 1230530.59/3
⇒ Volume(Sphere) = 410176.86
Therefore,
The volume of the sphere is 410176.90 ft³The volume of a sphere with a radius of 46.1 feet is 410176.9 cubic foot.
What is the volume of a sphere?The volume of sphere is the measure of space that can be occupied by a sphere. If the radius of the sphere formed is r and the volume of the sphere is V. Then, the volume of the sphere is given by: Volume of Sphere, V = (4/3)πr³
Given that, the radius of a sphere = 46.1 feet.
Here, volume = 4/3 ×3.14×46.1³
= 410176.864
≈ 410176.9 cubic foot
Therefore, the volume of a sphere with a radius of 46.1 feet is 410176.9 cubic foot.

21x + 5 is an exterior angle of the triangle , then
21x + 5 = 5 + 13x + 40
21x + 5 = 13x + 45 ( subtract 13x from both sides )

8x = 40 ( divide both sides by 8 )
