Students were surveyed to determine their favorite types of animals. The bar graph shows the number of students who selected each type of animal. 80% 5% 6% Type of Animal 20% Fish Lizard Bird 6 8 Number of Students What percentage of the students surveyed selected "Bird" as their favorite type of animal? Dog Cat 10 2 Favorite Animals 10
Answers
20% of the students surveyed selected "Bird" as their favorite type of animal. Hence option D is correct.
What is the percentage of Bird?To calculate the percentage of students who selected "Bird" as their favorite type of animal, we need to first determine the total number of students surveyed. From the bar graph, we can see that the total number of students is:
2 + 4 + 6 + 10 + 8 = 30
The number of students who selected "Bird" as their favorite type of animal is 6. To calculate the percentage, we can use the following formula:
Percentage = (Number of students who selected "Bird" / Total number of students surveyed) x 100%
Substituting the values we have:
Percentage = (6 / 30) x 100%
Percentage = 20%
Therefore, 20% of the students surveyed selected "Bird" as their favorite type of animal.

Mrs. Jones makes scented candles and wax warmers. The table shows the ratio of the number of candles to the number of wax warmers she makes.
candles: 7, 14, 21, 28, 77
wax warmers: 5, 10, 15, 20, ?
How many wax warmers will she make when she makes 77 candles?
A. 75
B. 40
C. 55
D. 69
Answers
The ratio of candles to wax warmers is 7:5, 14:10, 21:15, 28:20, 77:x.
We can simplify the ratio by dividing each side by its greatest common factor:
7:5 can be divided by 2 to get 7/2:5/2
14:10 can be divided by 2 to get 7:5
21:15 can be divided by 3 to get 7:5
28:20 can be divided by 4 to get 7:5
Therefore, the missing value must be 55, since 77:55 is the simplified version of 77:x.
So when Mrs. Jones makes 77 candles, she will make 55 wax warmers.

Complete the chart in model it on the previous page. Describe and explain the relationship between the decimals for 2/6 and 4/6
Answers
Answer: The relationship between the decimals for 2/6 and 4/6 is that the decimal for 4/6 is twice the decimal for 2/6.
When we simplify 2/6, we get 1/3, which is equivalent to 0.33 as a decimal. When we simplify 4/6, we get 2/3, which is twice the value of 1/3. So the decimal for 4/6 is twice the decimal for 2/6, which means that they have a proportional relationship.

Area of the base is 9 square feet, the lateral face area is 27 square feet, Lateral surface area is 27 square feet and total surface area is 36 square feet.
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
The square has a side length of 3 ft
Area of the base is 3×3
Area of the base is 9 square feet
Now let us find the lateral face area = 2a√[(a²/4) + h²]
=2(3)√[(9/4) + 17.64]
=6√20
=27 square feet
Lateral surface area = a√(a²+4h²)
a=3, h=4.2
Lateral surface area = 3√(9+4(4.2)²)
= 3√(9+4(17.64))
3√(9+70.56
= 3√79.56
=3×9
=27 square feet
To find total surface area, we have to find the slant height by pythagoras theorem
(1.5)²+(4.2)²=l²
2.25+17.64=l²
20=l²
4.47=l
Now total surface area = a² + 2al
=3²+2(3)(4.47)
=9+26.82
=36 square feet
Hence, Area of the base is 9 square feet, the lateral face area is 27 square feet, Lateral surface area is 27 square feet and total surface area is 36 square feet.

Step-by-step explanation:
I know this answer is right because the numbers got larger as the letters went to the right which means increase and the answers and graph makes logical sense to me. Hopefully you get a good grade on this.
Answer:
The correct option is Option D) A=-0.7,B=-9/16,C=-0.4,D=-5/16
step by step:
From the number line we can observed that:
1) A, B, C and D lies between -1 and 0.
2) Point A and B lies between -1 and -0.5
3) Point C and D lies between -0.5 and 0
Therefore, the value of A and B must have a negative value lying between -1 and -0.5
Also, the value of C and D must have a negative value lying between -0.5 and 0.
Now consider the provided options.
Option A) A=-5/16,B=-9/16,C=-0.7,D=-0.4
This is Incorrect representation because the value of C and D should lying between -0.5 and 0.
Option B) A=-0.4,B=-0.7,C=-5/16,D=9/16
This is Incorrect representation because the value of A and B should lying between -1 and -0.5.
Option C) A=9/16,B=-5/16,C=-0.4,D=-0.7
This is Incorrect representation because the value of C and D should lying between -0.5 and 0.
Option D) A=-0.7,B=-9/16,C=-0.4,D=-5/16
Here the value of A and B lying between -1 and -0.5 also the value of C and D lying between -0.5 and 0.
Also they are in ascending order from -1 to 0.
Hence, the correct option is Option D) A=-0.7,B=-9/16,C=-0.4,D=-5/16

Solve the following equations.
1.) 1/5x - 2 = -3
2.) 15 = 10 - x/4
3.) x/3 - 12 = -2
4.) x/-2 + (-6) = 6
1/5x - 2 = -3
1/5x = -1
x = -1 : 1/5
x = -1 × 5
x = -5
15 = 10 - x/4
5 = -x/4
x = -5 : 1/4
x = -5 × 4
x = -20
x/3 - 12 = -2
x/3 = 10
x = 10 × 3
x = 30
x/-2 + (-6) = 6
x/-2 - 6 = 6
x/-2 = 12
x = -24
A random sample of the 900 passengers boarding a plane was asked if they had ever flown before.
Have flown before: 32 Have not flown before:18
Write a proportion that can be used to determine how many passengers have probably not flown before.
Answers
324 passengers
Step-by-step explanation:Total number of passengers that were boarding the plane = 900
Part of ratio of people who have flown a flight before = 32
Part of ratio of people who have not flown a flight before = 18
Ratio of the people who has flown to who has not flown a flight = 32 : 18
Sum of both the parts of ratio = 32 + 18
= 50
Total number of people who has flown a flight before = 32/50 * 900
= 576 people
Total number of people who has not flown a flight before = 18/50 * 900
= 324 people
Proportion = 32 : 18 :: 576 : 324
Hence, the number of people who has not flown a flight before is 324.
