Answer:
-5-2030-24Step-by-step explanation:
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

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
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.

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.

What is the surface area, in square inches, of the original box?
What is the total cost, in dollars, of 1 original box?
Answer:
Surface area of original box:
2((10)(6) + (10)(3) + (6)(3))
= 2(60 + 30 + 18)
= 2(108)
= 216 square inches
Total cost of one original box:
(216 / 144)(22¢ / square foot)
= 1.5 × 22¢ = 33¢
How would you solve this without S.A formulas
Answer:
Step-by-step explanation:
Length of the object = 4 ft
Breadth of the object = 4 ft
Height of the object = 3 ft
Volume / Area of the object = Length * Breadth * Height
= 4 * 4 * 3
= 48 ft³
Length of the cubical hole = 2 ft
Breadth of the cubical hole = 2 ft
Height of the cubical hole = 3 ft
Volume / Area of the cubical hole = Length * Breadth * Height
= 2 * 2 * 3
= 12 ft³
Remaining Area of the object = Area of the object - Area of the cubical hole
= 48 - 12 ft
= 36 ft
We can’t tell any area of a 3d object without it’s SA formulas.

Step-by-step explanation:

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

Complete the chart in model it on the previous page. Describe and explain the relationship between the decimals for 2/6 and 4/6
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.

Mason plays a game by flipping a fair coin. He wins if the coin lands facing heads-up. What is the probability, as a fraction, that Mason wins the game?
(I need an actual answer, pls)
Answer:
[tex]\frac{1}{2}[/tex]
Step-by-step explanation:
There are two ways a fair coin can land: heads and tails. Since there is an equal chance that the coin lands on heads and tails, there is half chance ([tex]\frac{1}{2}[/tex] or 50%) that the coin lands heads-up.
∴ Therefore, the probability as a fraction is [tex]\frac{1}{2}[/tex].
