Answer:

This table does represent a proportional relationship because the sale price and original price are going up at the constant rate of 10

Step-by-step explanation:

The equation of line is y = -x + 25 and the constant of proportionality is 5

A line's equation is written as y = mx + b, where m is the slope and b is the y-intercept.

Furthermore, y - y1 = m (x - x1).

y = second point's y-coordinate

y1 = point one's y-coordinate m = slope x = point two's x-coordinate

x1 = point one's x-coordinate

The slope is m = (y2 - y1) / (x2 - x1).

Given the data,

Let the line equation be written as A.

The value of A is now

Let P be the initial point ( 15 , 10 )

Let's call the second point Q. ( 25 , 20 )

The slope of the line is now m = (y2 - y1) / (x2 - x1).

m slope = \(\frac{(20-10)}{(25-15)}\)

m slope = \(\frac{-10}{10}\)

m slope = -1

The equation for the line is now y - y1 = m (x - x1).

y - 10 = -1 ( x - 15 )

Simplifying the equation yields y - 10 = -x + 15.

We get y = -x + 25 by adding 10 to both sides of the equation.

So, if the selling price x is $10, the original price y is $ 15.

Hence , the equation of line is y = -x + 25 and the constant of proportionality is 5

Answer:

top option:

"9/15, 9 to 15, 9:15

or

1/2, 1 to 2, 1:2"

Step-by-step explanation:

First, create a ratio of white tops to violet tops using the given information:

9 white tops : 18 violet tops

We can simplify this by dividing both sides by 9 to get:

1 white top : 2 violet tops         or         1 : 2

So, the answer is the topmost option or

"9/15, 9 to 15, 9:15

or

1/2, 1 to 2, 1:2".

Answer:

m = 111.5

j = 35.5

I really hope this is right ;(

Step-by-step explanation:

m = 3j + 5

j + 3j + 5 = 147
4j + 5 = 147
4j = 142
142 ÷ 4 = 35.5

So j = 35.5

3(35.5) + 5 = 111.5

Answer:

There are 56 oranges in the basket, since the ratio of apples to oranges is 9:7. To calculate this, you can use the proportion method. First, set up a proportion using the ratio of apples to oranges (9:7):

9/7 = x/128

Then, solve for x.

x = (9/7) * 128

x = 112

Answer:

72 and 56

Step-by-step explanation:

Ratio of apples in the basket = 9x

Ratio of oranges in the basket = 7x

Total fruits in the basket = 128

So, Apples + Oranges = Total fruit

9x + 7x = 128

16x = 128

x = 128 ÷ 16

x = 8

∴ So, number of apples = 9x --> 9*8 = 72 apples

number of oranges = 7x --> 7*8 = 56 oranges

Step-by-step explanation:

The cube root of 64 is the number which when multiplied by itself three times gives the product as 64. Since 64 can be expressed as 2 × 2 × 2 × 2 × 2 × 2. Therefore, the cube root of 64 = ∛(2 × 2 × 2 × 2 × 2 × 2) = 4.

The cube root of 64 is 4.

Before solving the question, let's understand the concept of cube root.

The cube root of a number is the value obtained by multiplying it by itself three times or thrice. When we multiply 3 by itself three times, we get 3 x 3 x 3 = 27 = 3³, so the cube root of 27 is 3. Thus, we can say that the cube root gives a value that is basically cubed.

The cube root is denoted by ∛

Now, we will find the cube root of 64.

Firstly, we have to find factor 64.

64 = 2 × 2 × 2 × 2 × 2 × 2.

64 = ∛4³

64 = 4

Therefore, the cube root of 64 is 4.

9 the rolls will result in a sum greater than 10 if the experiment is repeated 108 times.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

The theoretical probability of both rolls equaling a sum greater than 10 is 3 over 36.

As, Expected number of outcomes = theoretical probability * number of trials

Expected number of outcomes = 3/36 x 108

                                                    = 9

Thus, the required value is 9.
