in wich of the tables are x and y inversely proportional
A
x=1,2,3,4
y=6,3,2,1.5
B
x=2,3,5,7
y=7.5,5,3,2
C
x=1,3,4,24
y=24,8,6,1
D:
x=0.1,0.3,25,100
y=200,40,0.8,0.2
Answers
Answer:
A, C
Step-by-step explanation:
If it is inversely proportional then y = k/x
Let's try one by one for the options. (im replacing y and x in the equation and finding k to see if k is the same all throughout)
A.
6 = k/1 (k=6)
3 = k/2 (k=6)
2 = k/3 (k=6)
1.5 = k/4 (k=6)
Yes! It's the same everywhere so this is correct!
B.
7.5 = k/2 (k=15)
5 = k/3 (k=15)
3 = k/5 (k=15)
2 = k/7 (k=14)
For the last one k is not the same so nope. It is wrong.
C.
24 = k/1 (k=24)
8 = k/3 (k=24)
k = 6×4 = 24
k = 24×1 = 24
This is correct too.
D.
k = 0.1×200 = 20
k = 0.3×40 = 12
k = 0.8 × 25 = 20
We can already see that k is not the same everywhere.
Only A and C, x and y are inversely proportional for all of the values

the ratio of the number of oranges to apples to bananas is 8:5:2. if there are 120 fruits in total, how many bananas are there
Answers
Answer:
Step-by-step explanation:
To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.
Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.
The sum of the parts in the ratio is 8x + 5x + 2x = 15x.
We know that the total number of fruits is 120. Therefore, we can set up the following equation:
15x = 120
To solve for x, we divide both sides of the equation by 15:
x = 120 / 15
x = 8
Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:
Number of bananas = 2x = 2 * 8 = 16
So, there are 16 bananas in total.
We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.
This is the graph of f(x) = x+A/x+B. The grid lines in the graph are one unit apart. What is the value of A/B
Answers
The value of A/B is given as follows:
A/B = -2.
What are the asymptotes of a function f(x)?The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.The horizontal asymptote is the value of f(x) as x goes to infinity, as long as this value is different of infinity.From the graph, the function has a vertical asymptote at x = 1, hence the value of B is given as follows:
B = -1 -> as x + B = 0 -> x = -B = -1.
When x = 0, y = -2, hence the value of A is obtained as follows:
A/-1 = -2
A = 2.
Then the division is given as follows:
A/B = 2/-1 = -2.

Answer:
Point 1: (-6, -3)
Point 2: (4, 5)
Slope: 4/5
Step-by-step explanation:
The first point is to the left of the graph while the second is to the right.
Point 1: (-6, -3)
Point 2: (4, 5)
To find the slope you can use the formula
m=y2-y1/x2-x1=slope
Point 1) -6=x1 -3=y1
Point 2) 4=x2 5=y2
m=5-(-3)/4-(-6)=8/10=4/5
The slope is 4/5

The answer is √6 mi.
The formula is: d = √(3h/2)

h = 324 ft
d = √(3 * 324/2) = √486 = √(81 * 6) = √81 * √6 = 9√6 mi
Adam:
h = 400 ft
d = √(3 * 400/2) = √600 = √(100 * 6) = √100 * √6 = 10√6 mi

A wall is 12 feet long and 8 feet tall. There is a square window 4 feet long in the wall. What is the area of the wall surface?
1. 96 ft 2
2. 80 ft 2
3. 92 ft 2
4. 32 ft 2
Answers
Answer:
80 ft2
First let's find the total area of the wall: 12 x 8 = 96. Then, we need to subtract out the window. To find the area of the wall, we'll need to find the area of the window and subtract it from the total area of the wall: 4 x 8 = 32 | 96 - 32 = 64. However, I am assuming the height of the window is 8 feet. If the window is 1 foot tall, the answer is 92 feet. If the window is 4 feet tall, the answer is 80 feet.
(The first and last answers are incorrect) As there is no picture provided, as I am assuming there is a picture, please follow my instructions left for you above as to what the answer would be depending on the height of the window.

arctan(tan(theta)) = arctan(24/43)
Since arctan(tan(theta)) = theta (for -π/2 < theta < π/2), we have:

Using a calculator or a table of trigonometric functions, we can evaluate this as:
theta ≈ 29.5 degrees (rounded to one decimal place)
Therefore, the value of theta is approximately 29.5 degrees.

Answer:
x = 19
z = 105
Step-by-step explanation:
z + 75 = 180
z = 105
6x - 39 = 75
6x = 114
x = 19
Answer:
x = 19
z = 105
Step-by-step explanation:
Because these are two intersecting lines, the two opposite angles are equal:
6x - 39 = 75
Solving this equation gives you x:
6x = 114
x = 19
In order to solve for z, we must remember that two angles on a straight line are supplementary angles meaning that, if added together, they equal 180°. In this case:
75 + z = 180
Solving this equation gives you z:
z = 105

An orchard sells apples in 5.5‐pound bags. The orchard sells 65 bags of apples each day.
How many pounds of apples does the orchard sell in 1 week?
The orchard sells
pounds in 1 week.
Answers
Answer:
2502.5 pounds
Step-by-step explanation:
Answer:
2,503 pounds
Step-by-step explanation:
Multiply the amount of bags sold by the number of days within a week.
65 x 7 = 455
In 1 week 455 bags of apples are sold.
The next step is to multiply the total amount of bags sold in 1 week by the pound of 1 bag of apples.
455 x 5.5 = 2,502.5lbs
2,503lbs (rounding to the nearest whole number) of apples are sold in 1 week.

HELP PLEASE ! Find the height of the trapezoid

Since the trapezoid is 2 triangles plus a square, we can split it into a rectangle (the two triangles put together) and the square. Let's call the height "x". The trapezoid's area becomes 8x [the square]+2x[the traiangle]. But wait! It states that the area is 70m, so the expression becomes the equation 10x=70m, which is x=10. Therefore, the height is 10.

Answer:
594 square centimeters
The minimum amount of paint needed for two coats will be 297 square centimeters. Then the correct option is B.
What is the area?Surface area refers to the area of an open surface or the border of a multi-object, whereas the area of a plane region or plane field refers to the area of a form or planar material.
The shape is a combination of the rectangle and the triangle. Then the area of the shape is calculated as,
A = 1/2 x 18 x 9 + 18 x 12
A = 81 + 216
A = 297 square centimeters
The minimum amount of paint needed for two coats will be 297 square centimeters. Then the correct option is B.
