Answer:
6 and - 6
Step-by-step explanation:
Two numbers that are opposites and each more than 6 units away from 0 is (8, -8).
What is coordinate plane?A coordinate plane is a two-dimensional surface formed by two number lines. It is formed when a horizontal line (the X-axis) and a vertical line (the Y-axis) intersect at a point called the origin. The numbers on a coordinate grid are used to locate points.
Given that, two numbers that are opposites and each more than 6 units away from 0.
Opposites are basically two numbers that are at different sides of the number line. For example, -2 and 2 are opposites because they are the same distance away from 0 on a number line making them opposites. To make an opposite just take a positive number, and then add a negative to it (8, -8).
Therefore, two numbers that are opposites and each more than 6 units away from 0 is (8, -8).

Solve for r 12-1/5r=2r+1
Answer:
5r
Step-by-step explanation:
12−
1
5r
=
60r−1
5r
To solve the equation 12 - 1/5r = 2r + 1 for r, isolate the variable r on one side of the equation. The equation simplifies to 5 = 1, which is not possible. Therefore, there is no solution for r in this equation.
Explanation:To solve for r in the equation 12 - 1/5r = 2r + 1, we will isolate the variable r on one side of the equation.
Step 1: Combine like terms by adding 1/5r to both sides of the equation:
12 - 1/5r + 1/5r = 2r + 1 + 1/5r
12 = 2r + 1 + 1/5r
Step 2: Combine like terms by subtracting 1 from both sides of the equation:
12 - 1 = 2r + 1 - 1 + 1/5r
11 = 2r + 1/5r
Step 3: Combine like terms by finding a common denominator for the terms involving r:
11 = (10r + r)/5r
Step 4: Simplify the equation:
11 = (11r)/5r
Step 5: Multiply both sides of the equation by 5r to eliminate the denominator:
11 * 5r = 11r
55r = 11r
Step 6: Divide both sides of the equation by 11 to solve for r:
55r/11 = 11r/11
5r = r
Step 7: Divide both sides of the equation by r:
5r/r = r/r
5 = 1
No solution exists for this equation.

True or False
A proportional relationship is non- linear.
Answer:
False - Linear is a proportional relationship as it is a straight line.
False.
False. A proportional relationship is linear. In a proportional relationship, when one variable increases or decreases, the other variable also increases or decreases at a constant rate. This results in a straight-line graph passing through the origin (0,0). In contrast, a non-linear relationship does not exhibit constant rate of change and does not form a straight line when graphed.

Answer:
14.95
Step-by-step explanation:
Use a median calculator
Final answer:
To find the number in the middle of 8.6 and 21.3, you calculate their average by adding them together and dividing by two, resulting in 14.95.
Explanation:
To calculate the number in the middle of 8.6 and 21.3, we need to find the average of these two numbers. To do this, you add the two numbers together and then divide by two.
The calculation is therefore: (8.6 + 21.3) / 2.
Adding 8.6 and 21.3 gives us 29.9, and dividing 29.9 by 2 gives us 14.95. So, 14.95 is the number in the middle of 8.6 and 21.3.

Using a video camera positioned on a table, Kat records her hanging flower basket to find out what is eating the blooms. The camera is positioned so that the line of sight to the basket forms a 25° angle of elevation. The camera sits 42 inches above the ground and the base of the table is 72 inches from the base of the rod the flower basket hangs on. To the nearest tenth of an inch, how high above the ground is the flower basket?
Edit: I got the answer it's 75.5
Answer:
75.5
Step-by-step explanation:
The correct height of the flower basket above the ground is 75.5 inches.
To determine the height of the flower basket above the ground, we can use trigonometry. The camera forms a 25 ° angle of elevation with the flower basket, and the distance from the camera to the base of the rod is given as 72 inches. We also know that the camera is positioned 42 inches above the ground.
We can use the tangent function, which relates the angle of elevation to the opposite side (the height of the flower basket above the camera's height) and the adjacent side (the horizontal distance from the camera to the rod).
Let's denote the total height of the flower basket above the ground as h, and the height of the camera above the ground as [tex]h_c[/tex] = 42 inches. The height of the flower basket above the camera is then [tex]\( h - h_c \)[/tex].
Using the tangent function:
[tex]\tan(25\°) = \frac{\text{opposite}}{\text{adjacent}}[/tex]
[tex]= \frac{h - h_c}{72}[/tex]
We can solve for h:
[tex]\[ h - h_c = 72 \times \tan(25\°) \][/tex]
[tex]\[ h = 72 \times \tan(25\°) + h_c \][/tex]
Now we calculate the value of tan(25°) and substitute the known values:
[tex]\[ h = 72 \times \tan(25\°) + 42 \][/tex]
Using a calculator, we find that 25° is approximately 0.4663. Plugging this value into the equation gives us:
h = 72 x 0.4663 + 42
h = 33.5 + 42
h = 75.5
Therefore, the flower basket is approximately 75.5 inches above the ground.

The amount of money A, accrued at the end of n years when a certain amount, P is invested at a compound annual rate, r, is given by A=P(1+r)n. If a person invests $150 in a account that pays 10% interest compounded annually, find the balance after 5 years .
Answer:
$241.58
Step-by-step explanation:
he amount of money A, accrued at the end of n years when a certain amount, P is invested at a compound annual rate, r, is given by:
[tex]A=P(1+r)^n[/tex]
From the given information:
P =$150
r=10%=0.1
n= 5 years
Therefore the balance after 5 years is:
[tex]A=P(1+r)^n\\=150(1+0.1)^5\\=150*1.1^5\\=\$241.58[/tex]
The balance of the account after 5 years, with an initial investment of $150 and an annual interest rate of 10%, compunded annually, would be approximately $241.58.
Explanation:To find the balance of the investment after 5 years, we substitute the values into the given formula. P is the principal amount which is $150, r is the annual interest rate which is 10% or 0.10 in decimal form, and n is the number of years which is 5. So the formula becomes A = $150 * (1 + 0.10)^5.
To simplify, calculate 1 + 0.10 to get 1.1. Then raise 1.1 to the power of 5 to get 1.61051. Multiply that by $150 to get approximately $241.58. So, the balance of the investment after 5 years would be approximately $241.58.

A photo is printed on a 20-inch by 24-inch piece of paper. The photo covers 320 square inches and has a uniform border. What is the width of the border?
Answer: The width of the border is 4 inches
Step-by-step explanation: The paper frame has its dimensions given as 20 inch by 24 inch. That means the area of the paper frame would be;
Area = L x W
Area = 20 x 24
Area = 480 square inches.
However, the photo itself covers an area of 320 square inches of this total surface area. If the photo has a uniform border, that means the photo and the paper frame are best described as congruent parallelograms (similar rectangles).
The ratio of the area of both paper frame and photo is given as;
Ratio = 480 : 320
Ratio = 3 : 2
When the length of the photo frame is given as 24, the length of the photo would be
3/2 = 24/L
L = (2 x 24)/3
L = 48/3
L = 16
Having calculated one side of the photo as 16 inches and the area has been given as 320 square inches, the other side of the photo is now derived as;
Area = L x W
320 = 16 x W
320/16 = W
20 = W
The dimensions of the paper frame is given as 24 inches and 20 inches, while those of the photo is given as 20 inches by 16 inches. The difference in both dimensions is 4 inches on either side (24 - 20 = 4, and 20 - 16 = 4)
Therefore the width of the border is 4 inches

Andrew draws triangle ABC. He then constructs a perpendicular bisector from vertex A that intersects side BC at point D. What can Andrew conclude, based on his drawing?
AB = BC
BD = DC
AD = BC
AC = BC
Answer:
BD = DCStep-by-step explanation:
A perpendicular bisector is a line segment that goes form a vertex to its opposite side. The important characteristic is that a perpendicular bisector intersects the opposide at the mid point and with a right angle, that's why is called perpendicular and bisector.
So, Andrew can conclude that side BC is divide equally, that is, BD = DC.
Therefore, the right answer is the second choice.
Based on the given information after drawing the triangle Andrew can conclude only BD = DC.
Use the concept of triangle defined as:
A triangle is a three-sided polygon, which has three vertices and three angles which has a sum of 180 degrees.
Given that,
Andrew draws triangle ABC.
He constructs a perpendicular bisector from vertex A.
The perpendicular bisector intersects side BC at point D.
Based on Andrew's drawing,
He can conclude that BD is equal to DC.
The perpendicular bisector from vertex A divides side BC into two equal parts, making BD and DC congruent.
However, Andrew cannot conclude that AB is equal to BC,
AD is equal to BC, or AC is equal to BC based on the given information.
Hence,
For this triangle Andrew can conclude only BD = DC.
