a. The table represents a proportional relationship

b. The constant of proportionality is 5/6

<h3 /><h3 /><h3>Proportional relationship:</h3>

Proportional relationship are relationship between variable where their ratios are equivalent. The variables in our case are total weight(pounds) and number of books.

Therefore, let's check if the table represent a proportional relationship.

let

total weight = x

number of book = y

k = constant of proportionality

y = kx

10 = k12

k = 10 / 12 = 5 / 6

y = kx

15 = 18k

k = 15 / 18

k = 5 / 6

y = kx

25 = 30k

k = 25 / 30

k = 5 / 6

y = kx

50 = k60

k = 50/60 = 5 / 6

The constant of proportionality is the same. Therefore, the table represents a proportional relationship

The constant of proportionality(k) is 5/6.

Can u guys help me please dont steal or guess ( will give brainiest for proof)
Novay_Z [31]

Answer:

30 feet

Step-by-step explanation:

To find the distance use a trigonometric ratio. Since we are looking for the hypotenuse and we are given the opposite side we will be using the ration of sine. We can set up the equation like this by using x as the measure we are looking for.

Sin of x=Opposite leg/Hypotnuse

Sin of 30= 15/x

Multiply by x and then divide by Sin of 30 to isolate the x.

x=15/Sin of 30

Plug it in to a calculator.

x=30

The price that a company charged for a basketball hoop is given by the equation 50-5x^2 where x is the number of hoops that are
Debora [2.8K]
Given:
Profit : 15,000,000
Cost: 30 per basketball hoop
production: 1 million hoops
price: 50 - 5x²

Profit = Sales - Cost
15,000,000 = sales - 30(1,000,000)
15,000,000 + 30,000,000 = sales
45,000,000 = sales

45,000,000 / 1,000,000 = 45 sales price.

Mr. Austin is driving 390 miles to visit the Gateway Arch in St. Louis, Missouri. He dries at an average rate of 65 miles per ho
Lapatulllka [165]

Answer:

the time needed to get to the arch is 6 per hour

Step-by-step explanation:

The computation of the time needed to get to the arch is shown below:

As we know that

Speed = distance ÷ time

where,

Speed is 65 miles per hour

And, the distance is 390 miles

So, the time is

= 390 ÷ 65

= 6 per hour

Hence, the time needed to get to the arch is 6 per hour

We simply applied the above formula so that the correct value could come

And, the same is to be considered
