With respect to the proportional relationship table, Harry can run 2.6 miles in 28.6 minutes

What is the proportional relationship?

If all of the ratios of the variables are equal, then there is a proportional link between the two variables. In a proportional relationship, one variable is, in other words, always a constant value multiplied by the other variable. In other words, a relationship is proportional if it can be explained by multiplying each pair of data values by a certain amount.

Solution Explained:

A/Q, the table shows the proportional relationship between distance and time.

Given,

Distance                   Time
0.7                             7.7
1.4                              15.4
x                                 28.6

We know, the ratios are equivalent in a proportional relationship
If we divide, 0.7 and 7.7, we get 11
so taking 11 as the constant of proportionality, we get

x X 11 = 28.6
x = 28.6 / 11
x = 2.6

Therefore, Harry can run 2.6 miles in 28.6 minutes.

Answer:

x is equal to 10 times 5 is the ans

Answer: x=18 inches.

Step-by-step explanation:

You can use the Pythagorean Theorem for help.

To find the length of the third side of a right triangle, you have to do

10 square + 15 square=x square.

100+225=x square

325=x square

x=  [tex]\sqrt{325}[/tex].

The nearest inch would be x= 18 inches.

Answer:  The correct answer is 18 inches

Step-by-step explanation:

Using the Pythagorean Theorem:

c= [tex]\sqrt{a^2+b^2}[/tex]

c=[tex]\sqrt{10^2+15^2}[/tex]

c=18.02776

c= 18 inches

The number of these patients on average per day that do not have insurance and thus pay cash price for their visits would be = 504 people.

An insurance coverage is defined as the official coverage an individual has over unforseen and inexperienced financial demands.

The average number of patients seen in a day = 22.4.

The number of months patients where seen = 3 months = 90 days

Total number of patients seen would be= 22.4 × 90 = 2,016

The fraction of patients that has insurance= 3/4

Therefore the fraction that doesn't have insurance= 1/4 of 2,016

= 2,016/4

= 504 people.

By solving a quotient, we will see that there are 13.33 servings of pasta on Lois' dish.

We know that one serving of pasta is 0.4 cups, and we know that Lois made a dish with (5 + 1/3) cups of pasta.

To see how many servings are in that dish, we need to take the quotient between the total number of cups used and the cups of a single serving.

So we need to solve:

N = (5 + 1/3)/0.4

We can write the numerator as:

5 + 1/3 = 15/3 + 1/3 = 16/3

The denominator as:

0.4 = 4/10 = 2/5

Then the quotient becomes:

N = (16/3)/(2/5)

N = (16/3)*(5/2) = (16*5)/(3*2) = 80/6 = 13.33

There are 13.33 servings on Lois' dish.

Step-by-step explanation:

The length of the second side of the triangle is 18 m

What is the perimeter of a Triangle?

The perimeter of a triangle is given by the formula

Perimeter of a triangle = Sum of all three sides

Let the sides of the triangle be a , b , c

Perimeter of a triangle = a + b + c

Given data ,

Perimeter of the triangle = 51 m

Let the first side , second side and third side of the triangle be a , b and c respectively

So , a + b + c = 51 m

And , The second side is twice as long as the first

So , b = 2a

And , The third side is 3 meters less than three times the first

So , c = 3a - 3

Substituting the values of a , b and c in the perimeter equation , we get

a + 2a + 3a - 3 = 51

6a - 3 = 51

Adding 3 on both sides , we get

6a = 54

Divide by 6 on both sides , we get

a = 9 m

Substituting the value of a , we get

b = 2a

b = 2 x 9

b = 18 m

c = 3a - 3

c = 3 x 9 - 3

c = 27 - 3

c = 24 m

So the length of the first side , second side and third side is 9m , 18 m and 24 m respectively

Hence , the length of the second side is 18 m

The conversion of 30 miles per second into miles per minute is 1800 miles per minute and Mercury will travel 5400 miles in 3 minutes at this rate.

According to the question,

We have the following information:

Mercury travels at a rate of approximately 30 miles per second.

We know that there are 1/60 minutes in 1 second.

So, we have the following expression for conversion:

30/(1/60) miles per minute

30*60

1800 miles per minute

Now, we know that following formula is used to find distance:

Distance = speed*time

Distance = 1800*3

Distance = 5400 miles

Hence, the conversion of 30 miles per second into miles per minute is 1800 miles per minute and Mercury will travel 5400 miles in 3 minutes at this rate.

The given system of equations has no solution.

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

The general equation of a quadratic equation is -

y = ax² + bx + c

We have the following equations -

y = x² + 6x + 3

y = 3x - 7​

Plot the graph of both equations and the points of intersection would be the solution set. Refer to the graph below. There are no points of intersection, hence these set of equations have no solution.

A function is a rule that maps the elements of one set A to the elements of another set B such that each element of A maps directly to only one element of B.

By using the given chart, the value of h'(4) would be -16.

What is a chain rule in calculus?

According to the chain rule, the derivative of f(g(x)) is f'(g(x)).g' (x). In other words, it aids in the differentiation of 'composite functions'.

Sin(x²), for example, is a composite function because it can be written as f(g(x)) where f(x)=sin(x) and g(x)=x².

The given function is

                                h(x) = f(g(x))

            Now differentiating the above function with respect to x, we get

                               h'(x) = f'(g(x)) * g'(x)

                     Now find h'(4), so put x = 4, we get

                               h'(4) = f'(g(4)) * g'(4)

                     By using the given table, we can write
