True or False: a = 6 is a solution to the inequalty a > 6.
Answer:
False
Step-by-step explanation:
If you do a = 6, then you get 6 > 6 which is not true. 6 isn't greater than itself.
Answer:
False
Step-by-step explanation:
Your inequality shows that a is greater than 6, thus meaning can not equal 6.

Answer: 15%
Step-by-step explanation:
the percent is equal to (large double Cheeseburgers/total burgers) * 100
finding values
num of large double cheeseburgers in the table = 60
total burgers by adding all the values up = 68+77+45+98+52+60 = 400
calculating percent
so the percent is (60 / 400) * 100 = 15%

An oak tree is 12 feet tall and a bird is standing on the ground 16 feet from the tree. If the bird flies directly to the top of the tree, how far will it fly?
Answer:
20 ft.
Step-by-step explanation:
There are two different (yet similar) ways to solve this problem:
a. Pythagorean theorem
b. Pythagorean triplet recognition
With option "a", you set it up:
12² + 16² = x²
144 + 256 = x²
400 = x²
x = 20
But, the arguably "easier" way to find out the distance is to use the Pythagorean's triplet recognition.
We know that the most common right triangle is the 3-4-5 right triangle.
If you take the three side lengths, and multiple them by the same thing, those are the sides to another right triangle.
ex. 3-4-5 * 5
15-20-25 are the sides of another right triangle!
This also means that if you have a triangle that has the sides 15, 20, and 25, you immediately know it's a right triangle.
When we look at 12 and 16, we know they are the legs of the triangle.
We also know that if we multiply 4 times 3 and 4, it will equal 12 and 16.
So what's 5 times 4? 20!
Final answer:
To find how far the bird will fly to the top of the tree, we use the Pythagorean Theorem. By squaring the height of the tree and the distance from the bird to the tree, we find that the hypotenuse, or the distance the bird will fly, is 20 feet.
Explanation:
The question asks about the distance a bird will fly from the ground to the top of a tree, which involves the application of the Pythagorean Theorem to solve for the hypotenuse of a right triangle. The tree's height (12 feet) represents one leg of the right triangle, and the distance from the bird to the tree (16 feet) represents the other leg. To find the distance the bird flies (the hypotenuse), we use the equation:
a² + b² = c²
Where ‘a’ and ‘b’ are the lengths of the legs, and ‘c’ is the length of the hypotenuse. Now we can calculate it:
12² + 16² = c²
144 + 256 = c²
400 = c²
[tex]\sqrt{400}[/tex] = c
20 feet = c
Therefore, the bird will fly 20 feet to reach the top of the oak tree.
this partial Circle has a radius of 11 in what is the area of this figure use 3.14 for pi enter your answer as a decimal in the Box round your answer to the nearest hundredth
Answer:
190 square inch
Step-by-step explanation:
Area of the partial circle = 1/2 pi r^2
Pi = 3.14
Radius r = 11 inch
Area = 1/2 x 3.14 x (11)^2
= 1/2 x 3.14 x 11 x 11
Multiply through
= 3.14 x 11 x 11 /2
= 379.94/2
= 189.97
= 190 square inch
The model of a new apartment building is shown. The
architect plans for the building to be 144 times the
dimensions of the model. What will be the volume and
surface area of the new building when it is completed?
To find the dimensions of the actual floor of the new building, multiply the dimensions of the model by the scale factor. The volume of the new building is found by multiplying the dimensions of the actual floor by the height. The surface area is calculated by summing the areas of all six faces of the rectangular prism.
Explanation:To find the dimensions of the actual floor, we need to multiply the dimensions of the model by the scale factor. Let's assume the dimensions of the model floor are length = 10 meters and width = 5 meters. Since the architect plans for the building to be 144 times the dimensions of the model, the length of the actual floor would be 10 x 144 = 1440 meters and the width would be 5 x 144 = 720 meters.
The volume of a rectangular prism (the building) can be calculated by multiplying its length, width, and height. Assuming the height is 3 meters, the volume of the new building would be 1440 x 720 x 3 = 2,073,600 cubic meters.
The surface area of the new building can be calculated by summing the areas of all six faces of the rectangular prism. The formula for surface area is 2*(length x width + width x height + height x length). Using the dimensions from before, the surface area would be 2*(1440 x 720 + 720 x 3 + 3 x 1440) = 2,394,240 square meters.
A square has a perimeter of 20 cm. A new square is
created that has double the perimeter of the original
square. How does the area of the new square
compare to the area of the original square?
The area quadrupled. If the original square's perimeter is 20, each side length must be 5. The new square has double the perimeter, so it's 40. This means each side of the new square must be 10.
The formula for area in a square is base x height.
Square 1 area: 5x5 = 25
Square 2 area: 10x10 = 100
100/25 is 4, so the original square's area is 4 times smaller than the new square.

How many solutions can be found for the system of linear equations represented on the graph?
no solution
one solution
two solutions
infinitely many solutions
The system of linear equations represented on the graph has infinitely many solutions.
Explanation:To determine the number of solutions for the system of linear equations, we can start by solving the equations. We can solve the first equation for y to get y = x + 2. We can substitute this expression for y into the second equation and then solve for x. By substituting y = x + 2 into -3x + 3y = 6, we get -3x + 3(x + 2) = 6. Simplifying this equation gives us -3x + 3x + 6 = 6, which simplifies further to 6 = 6. This equation is always true, which means there are infinitely many solutions for the system of linear equations. The two equations represent the same line, and any point on this line is a solution to the system.

A line with a slope of 8 passes through the points (9,v) and (8,2). What is the value of v?
Answer:
Step-by-step explanation:
Given that,
Slope of line is 8
m=8
And we are given two points where the line pass through
(x1,y1) = (9,v). ; x1=9, y1=v
(x2,y2)= (8,2). ; x2=8, y2=2
The slope of a line is given as
m=∆y/∆x
m=(y2-y1)/(x2-x1)
8=(2-v)/(8-9)
8=(2-v)/(-1)
Cross multiply
8×-1=2-v
-8=2-v
Subtract 2 from both sides
-8-2=2-v-2
-10=-v
Divide both sides by -1
-10/-1=-v/-1
Note, -÷-=+
10=v
Then v=10
We can write this as an expression:
[tex]\frac{2-v}{8-9}=8[/tex] → [tex]\frac{2-v}{-1}=8[/tex]
Now, lets solve for v.
[tex]\frac{2-v}{-1}=8[/tex]
~Multiply -1 to both sides
[tex]\frac{2-v}{-1}[/tex] * -1 = 8 * -1
~Simplify
2 - v = -8
~Subtract 2 to both sides
2 - 2 - v = -8 - 2
~Simplify
-v = -10
~Divide -1 to both sides
-v/-1 = -10/-1
~Simplify
v = 10

What are the minimum and maximum values of t for which |t + 3| ≤ 2
Answer:
Max value for t is -1 and minimum value for t is -5
Step-by-step explanation:
Make two inequalities in regards to absolute value and solve both for t:
t+3<=2 and t+3>=-2
t<=-1 and t>=-5
The compound inequality would be -1>=t>=-5
Solving the absolute value inequality, it is found that:

Game 1 gives you 200 points every time you
score. Game 2 doubles your points every time you
score (2, 4, 8, and so on). In which game do you
think you will you earn more points?
While Game 1 offers a steady 200 points per score, Game 2's point doubling system will eventually surpass Game 1's linear growth, leading to higher earnings in Game 2 over time.
To decide in which game you will earn more points, let's consider the point growth in both games. In Game 1, you receive a constant 200 points every time you score. This represents a linear growth.
However, in Game 2, your points double every time you score, starting from 2 points (2, 4, 8, 16, and so on).
This is an example of exponential growth.When comparing linear growth to exponential growth, exponential growth will eventually outpace linear growth. Initially, Game 1 will give you more points (as 200 is greater than 2, 4, 8).
However, after a certain number of scores, Game 2 will start to give you more points per score. Once you've doubled a few times, the number of points you earn in Game 2 will surpass the constant 200 points reward of Game 1.
