Amy has 20 necklaces in a jewelry box. The probability of reaching into the jewelry box and pulling out a silver necklace is 0.85. What is the probability that Amy will reach in the jewelry box and pull out a necklace that is not silver?
Answer:
0.15
Step-by-step explanation:
Given
[tex]Necklaces = 20[/tex]
Represent the probability of pulling out silver with p; So:
[tex]p = 0.85[/tex]
Required
Determine the probability of not pulling silver
This question is to test probability complements
And the complement rule of probability states that:
[tex]p + q = 1[/tex]
Where q and p are opposites. In other words:
q = probability of not pulling out silver
Substitute 0.85 for p in [tex]p + q = 1[/tex]
[tex]0.85 + q = 1[/tex]
Make q the subject
[tex]q = 1 - 0.85[/tex]
[tex]q = 0.15[/tex]
Hence, the required probability is 0.15

Chase took a taxi from his house to the airport. The taxi company charged a pick-up fee of $1.20 plus $4.75 per mile. The total fare was $48.70, not including the tip. Write and solve an equation which can be used to determine xx, the number of miles in the taxi ride. i need the equation and the answer of what is x
Answer:
(48.70-1.20)/4.75 = x x=10
Step-by-step explanation:
you should get the x by its self by moving the 1.20 over to the other side then divide by the 4.75 this would get x by its self leaving you to answer and get an answer of 10
Chase rode the taxi for 10 miles.
Let the number of miles in the taxi ride be represented by x.
Pick up fee = $1.20
Amount per mile = $4.75 per mile.
Therefore, the number of miles in the taxi ride will be:
1.20 + (4.75 × x) = 48.70
1.20 + 4.75x = 48.70
Collect like terms
4.75x = 48.70 - 1.20
4.75x = 47.50
Divide both side by 4.75
4.75x/4.75 = 47.50/4.75.
x = 10
Therefore, the number of miles is 10 miles

Bev has to cut her grandma's grass this weekend and wants to know exactly how much area she will be cutting. Calculate the area of the polygon. Be sure to show all your work and explain your answer.
Six-sided polygon that includes two isosceles right triangles, one with height and base of 15 feet, the other height and base of 4 feet, and one rectangle measuring 25 feet by 4 feet.Which of the following best describes an anecdote?
Answer:
25 feet by 4 feet
Step-by-step explanation:
Answer:
This shape is an irregular polygon. This means we have to find the area of the whole shape and then subtract the missing parts to get the correct answer.
First, we have to find the area of the whole shape (a rectangle). The formula for a rectangle's area is:
The length of the shape is 19 ft, and the width is 29 ft. Now, we apply the formula to those numbers:
Now that we know that the area of the whole polygon is 551 square feet, we have to find the area of:
1. The first missing triangle
2. The second missing triangle
3. The missing rectangle
Add all of those areas together, and then subtract them from 551 and we have the answer.
First, we find the area of the missing triangle in the top left hand corner. The area formula for a triangle is
So, we have to find the base and the height. We see that part of the whole polygon's width is 4 ft, which is not missing, so we subtract that from the total width, 19 ft.
This means that the triangle's base is 15 ft. Now, we have to find the height. We can easily see that the height is 15 ft, as it says so in the picture.
Now, we just have to apply the formula:
So, we have our first area, 112 square feet.
Now we have to find the area of the second missing triangle in the bottom right corner.
We know that the base is 4 ft, as it says so in the picture. The height is 24 ft. We know that the total height of the polygon is 29 ft, and we see a shaded part of 25 ft in height. So:
According to this equation, we have 4 ft in height. Using the area formula for triangles, here is our equation:
This equation states that our second area is 8 square feet.
Now, we just have our last area to find, the missing rectangle. According to all of the previous information, and the picture, we see that the width is 15 ft and the height is 14 ft. Now we apply the area formula for rectangles:
Lastly we add up all of our areas: 112.5 square feet, 8 square feet, and 210 square feet.
Then, we subtract 330.5 from 551:
The answer is 220.5

Usually Holly leaves home to school at 9:00, however today she left home 20 minutes later. In order to be at school on time she increased her usual speed by 20% and still was at school 15 minutes later than usual. What is her usual time from home to school
Answer:
Her usual time from home to school is 30 minutes
Step-by-step explanation:
At any point in time;
distance = speed * time
Here, we want to calculate the normal time she spent going from home to school
Let the normal time be x minutes
And the normal speed be t m/min
Today, she increased her speed by 20%
Her speed today will be t + 20/100 * t =
1.2t m/min
Her distance from how to school normally is
xt meters
Now what this means is that, at the increased speed, she was able to get to school 5 minutes earlier
What we are saying is although, she lost 20 minutes initially, she was able to beat down the lateness by 5 minutes
So, the time spent on her increased speed journey is;
(x-5) minutes
At any point in time, the distance will be equal;
Thus, mathematically;
xt = 1.2t(x-5)
xt = 1.2xt - 6t
6t = 1.2xt-xt
6t = 0.2xt
t cancels out
0.2x = 6
x = 6/0.2
x = 30 minutes
Point A (12, 4) is the image of point A(3, 1) under a dilation with respect to the origin. What is the constant of dilation?
Answer:
We conclude that the constant of dilation is: 4
Step-by-step explanation:
We know that when an object is dilated by a scale factor, it gets reduced, stretched, or remains the same, depending upon the value of the scale factor.
If the scale factor > 1, the image is enlargedIf the scale factor is between 0 and 1, it gets shrunkIf the scale factor = 1, the object and the image are congruentThe coordinates of the image point can be determined by multiplying the coordinates of the original point by a certain scale factor.
Given the point A'(12, 4) is the image of A(3, 1).
It is clear that the image point A'(12, 4) is enlarged 4 times of the original point A(3, 1).
It means the image point A'(12, 4) is determined when the original point A(3, 1) is dilated by a scale factor of 4.
i.e.
A(3, 1) → A'(4(3), 4(1)) → A' (12, 4)
Therefore, the rule of dilation by a scale factor 4 is:
P(x, y) → P'(4x, 4y)
Hence, we conclude that the constant of dilation is: 4

An auditorium has 51 rows of seats. The first row contains 70 seats. As you move to the rear of the auditorium, each row has 6 more seats than the previous row.
1. How many seats are in row 12 ,136?
2. How many seats are in the auditorium?
Answer:
seats are in row 12 is 136
seats are in row 136 is 880
seats are in the auditorium is 1071000
Step-by-step explanation:
given data
rows of seat = 51
first row seats = 70
each row seats = 6
to find out
How many seats are in row 12 ,136 and How many seats are in the auditorium
solution
it is AP as 70 , 76 , 82, 88 ............
here A = 70 , d = 6
for n = 12 and 136
so An = a + (n-1)d .........1
A(12) = 70 + (12-1)6
A(12) = 136
and
A(136) = 70 + (136-1)6
A(136) = 880
and
for total seat we get here Sn for 51 row
Sn = [tex]\frac{n}{2}[/tex] × [ 2a(n-1)d] ...........2
put here value
Sn = [tex]\frac{51}{2}[/tex] × [ 2(70)(51-1)6]
Sn = 1071000
