In the rectangle below, the line MN cuts the rectangle into two regions. Find x, the length of segment NB, so that the area of the quadrilateral MNBC is 40% of the total area of the rectangle.
Answers
The length of segment NB is 0.833
Finding x, the length of segment NBFrom the question, we have the following parameters that can be used in our computation:
The rectangle
The area of the rectangle is
Area = (20 + x) * 10
The area of MNBC is
Area = 1/2 * 10 * (x + 20 + x - 5)
Area = 5(2x + 15 )
The area of the quadrilateral MNBC is 40% of the total area of the rectangle
So, we have
5(2x + 15) = 40% * (20 + x) * 10
5(2x + 15) = 4* (20 + x)
When evaluated, we have
x = 0.833

Find the total of question (probability of choosing green) = 2
set as a fraction:
Numerator = amount needed (2)
Denominator = all things/objects involved (10)

With probability there is a good chance the answer is going to be less than 1 or 100%, knowing that can help to tell which number goes in what place of the fraction

Answers
The coordinates of vertices N'G'M' are N'(-10, -15), M'(-15, -5) and G'(-5, -10).
From the given graph, N(-4, 6), M(-6, 2) and G(-2, 4).
Scale factor = \(2\frac{1}{2}\)
= 2.5
The reflection of point (x, y) across the x-axis is (x, -y).
Here, N(-4, 6)→(-4, -6)
M(-6, 2)→(-6, -2)
G(-2, 4)→(-2, -4)
Now, with scale factor 2.5, we get
(-4, -6)→2.5(-4, -6)→N'(-10, -15)
(-6, -2)→2.5(-6, -2)→M'(-15, -5)
(-2, -4)→2.5(-2, -4)→G'(-5, -10)
Therefore, the coordinates of vertices N'G'M' are N'(-10, -15), M'(-15, -5) and G'(-5, -10).

If the variance of a variable is 16, what is the standard deviation?
Answers
Answer:
Standard deviation=4
Step-by-step explanation:
Standard deviation = square root of variance
Standard deviation=√variance
Variance=standard deviation square
Variance=standard deviation^2
From the question
Variance=16
Standard deviation=?
Standard deviation=√variance
=√16
=4
Standard deviation=4
check:
If standard deviation=4
Variance=standard deviation^2
=4^2

156
Total

240
Explanation:
From the information given, we know that 35% of the 240 students surveyed were interested in athletics, which means 0.35 x 240 = 84 students were interested in athletics. We also know that 3/5 of the students were interested in academic clubs, which means 3/5 x 240 = 144 students were interested in academic clubs.
We are also given that a total of 26 students were interested in both athletics and academic clubs, which means this number should go in the cell that represents the intersection of the "Interested in Athletics" column and the "Interested in Academic Clubs" row.
To fill in the remaining blanks, we can use the following relationships:
The total number of students interested in athletics is 84, which means the number of students who are interested in athletics but not academic clubs is 84 - 26 = 58. This goes in the cell that represents the intersection of the "Interested in Athletics" column and the "Not Interested in Academic Clubs" row.
The total number of students interested in academic clubs is 144, which means the number of students who are interested in academic clubs but not athletics is 144 - 26 = 118. This goes in the cell that represents the intersection of the "Not Interested in Athletics" column and the "Interested in Academic Clubs" row.
The total number of students who are not interested in athletics is 240 - 84 = 156, which means the number of students who are not interested in athletics or academic clubs is 156 - 38 = 118. This goes in the cell that represents the intersection of the "Not Interested in Athletics" column and the "Not Interested in Academic Clubs" row.
Finally, we can calculate the total number of students who are not interested in academic clubs by subtracting the number of students interested in academic clubs (144) from the total number of students (240), which gives us 240 - 144 = 96. This goes in the cell that represents the intersection of the "Interested in Athletics" column and the "Not Interested in Academic Clubs" row.

Here is a double number line showing that it costs $3 to buy 2 bags of rice:
1. At this rate, how many bags of rice can you buy with $12? ___________
2. Find the cost per bag. _____________
3. How much do 20 bags of rice cost? _____________
Answers
Answer:
1. 8 bags of rice
2. $1.50 per bag
3. $30
Step-by-step explanation:
For #1, you set up the proportion 3 over 2 is equal to 12 over x and solve by cross multiplication. Then, you should get the answer of 8 bags. For #2, you do $3 divided by 2 to get the answer of $1.50. For #3, you use your answer from #2 and do 1.5 times 20 to get $30.
1. The cost of 12 bags of rice is 18 dollars.
2. Per bag of rice cots 1.5 dollars.
3. The cost of 20 bags of rice is 30 dollars.
What is a unitary method?A unitary method is a mathematical technique for determining the value of a single unit then we can derive any no. of units by multiplying it by the single unit.
Given it costs 3 dollars for 2 bags of rice.
We know if we determine the cost of one bag of rice we can find out the cost of any no. bags of rice.
∴ 2 bags of rice cost 3 dollars,
So, 1 bag of rice cots (3/2) dollars = 1.5 dollars.
1. At the rate of 1.5 dollars per bag of rice 12 bags of rice will cost (1.5×12) dollars = 18 dollars.
2. The cost per bag of rice is 1.5 dollars.
3. The cost of 20 bags of rice is (1.5×20) dollars = 30 dollars.

How can I find the cube root of 64?
Answers
Answer:
4
Step-by-step explanation:
The cube root of 64 is the number which when multiplied by itself three times gives the product as 64. Since 64 can be expressed as 2 × 2 × 2 × 2 × 2 × 2. Therefore, the cube root of 64 = ∛(2 × 2 × 2 × 2 × 2 × 2) = 4.
The cube root of 64 is 4.
Before solving the question, let's understand the concept of cube root.
The cube root of a number is the value obtained by multiplying it by itself three times or thrice. When we multiply 3 by itself three times, we get 3 x 3 x 3 = 27 = 3³, so the cube root of 27 is 3. Thus, we can say that the cube root gives a value that is basically cubed.
The cube root is denoted by ∛
Now, we will find the cube root of 64.
Firstly, we have to find factor 64.
64 = 2 × 2 × 2 × 2 × 2 × 2.
64 = ∛4³
64 = 4
Therefore, the cube root of 64 is 4.

Sula designs greeting cards for her friends. Each friend has a 30% chance to get a musical greeting card. Design a simulation that can be used to estimate the probability that a friend will receive a musical greeting card.
Answers
Here's a simple Python code that simulates the process:
```python
import random
num_friends = 1000 # the number of friends
num_musical_cards = 0 # the number of friends who received musical cards
# simulate the card distribution for each friend
for friend in range(num_friends):
if random.random() < 0.3:
num_musical_cards += 1
# calculate the probability of a friend receiving a musical card
prob = num_musical_cards / num_friends
print("Probability of a friend receiving a musical card:", prob)
```
In this simulation, we create a loop that simulates the card distribution for each friend. We randomly assign a musical card to each friend with a 30% chance. Then, we calculate the probability of a friend receiving a musical card by dividing the number of friends who received musical cards by the total number of friends.
You can adjust the `num_friends` and `random.random() < 0.3` parameters to match your specific scenario.

B. No, since there are two costs (in dollars) which have the same inputs (time in hours)
C. Yes, since each output (cost in dollars) has a single input (time in hours)
D. Yes, since each input (time in hours) has a single output (cost in dollars)

Answer:
No, since there are two inputs (time in hours) which have the same cost (in dollars). Therefore, option A is the correct answer.

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
From the given that,

3. The ______ projection shows the size and shape of continents accurately but distorts water areas.
A. Conic
B. Mercator
C. Robinson
D. Interrupted
Answers
The correct answer is A. Conic projection.
A conic projection is a type of map projection created by projecting the surface of a globe onto a cone. The cone is then unrolled and flattened to create a two-dimensional map. Conic projections are best for mapping small areas, such as individual countries or states. They are also good for mapping areas that are located near the equator.
Conic projections show the size and shape of continents accurately, but they distort water areas. This is because the cone is tangent to the globe at one point, and the further away from that point you get, the more distortion there is.
Mercator projection is a cylindrical map projection presented by Flemish geographer and cartographer Gerardus Mercator in 1569. It became the standard map projection for navigation because it is unique in representing north as up and south as down everywhere while preserving local directions and shapes. The map is thereby conformal. As a side effect, the Mercator projection inflates the size of objects away from the equator. This inflation is very small near the equator but accelerates with increasing latitude to become infinite at the poles.
Robinson projection is a map projection presented by American cartographer Arthur H. Robinson in 1963. It is a compromise projection that attempts to balance the distortions of area, shape, and distance. The Robinson projection is neither conformal nor equal-area, but it is pseudocylindrical, which means that the meridians are straight lines and the parallels are circles.
Interrupted projection is a type of map projection that is interrupted at regular intervals. This is done to reduce the distortion of the map. The most common type of interrupted projection is the Mercator projection, which is interrupted at the equator and the prime meridian
