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.

The total number of red roses sold by the florist is 455.

A Fraction represents the parts of a whole or collection of objects. The first and most common form of representing a fraction is [tex]\frac{a}{b}[/tex].

Here, a is the numerator, and b is the denominator.

Number of Roses sold by The florist = 715

Fraction for the number of red roses sold = [tex]\frac{7}{11}[/tex] (7 out of 11 roses)

We have to find the number of red roses sold by the florist.

Now,

The number of red roses sold by the florist will be

[tex]\frac{7}{11} \ of\ 715[/tex]

[tex]=\frac{7}{11}*715[/tex]

[tex]=\frac{7*715}{11}[/tex]

[tex]=\frac{5005}{11}[/tex]

[tex]=455[/tex]

Hence, the total number of red roses sold by the florist is 455.

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 amount of flour that is needed if the recipe in question is tripled, is 6 ³ / ₄ cups of flour

The recipe in question needs 2 ¹ / ₄ cups of flour in order to be completed. However, there is a need to triple the recipe to cater for the people being cooked for.

Going by proportionality, the number of cups of flour will also need to be tripled to ensure that it is the right quantity.

The amount of flour needed will therefore be:

= Flour needed in original recipe x 3

= 2 ¹ / ₄ x 3

= ( 4 x 2 + 1) / 4 x 3

= 9 /4 x 3

= 6.75 cups

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 length of the curve is 2.0036.

The equation of the curve is y = e^(x). The interval is 0 ≤ x ≤ 1. A curve is a smoothly drawn figure or line in a plane that has a bend or twist in it. A curve is defined as a continuous and smooth flowing line with no sudden twists. A curve is an abstract concept in mathematics that describes the path of a continuously moving point. The arc length of a curve y = f(x) in the increasing interval from a to b is given below.

[tex]L = \int\limits^a_b {\sqrt[]{ 1 + (\frac{dy}{dx})^{2}} \, dx[/tex]

dy/dx = d(e^x)/dx = e^x

(dy/dx)² = e^(2x)

The length of the given curve is calculated below.

[tex]L = \int\limits^1_0 {\sqrt[]{ 1 + e^{2x}}, dx[/tex]

L = [√(1+e^2x) + (1/2)ln(√(1+e^2x) - 1) - (1/2)ln(1 + √(1+e^2x))] from limits 0 to 1.

L = [√(1+e²) + (1/2)ln(√(1+e²) - 1) - (1/2)ln(1 + √(1+e²))] - [√(1+1) + (1/2)ln(√(1+1) - 1) - (1/2)ln(1 + √(1+1))]

L = [√(1+e²) + (1/2)ln(√(1+e²) - 1) - (1/2)ln(1 + √(1+e²))] - [√2 + (1/2)ln(√2 - 1) - (1/2)ln(1 + √2)]

The equation 56 ÷ 8 + 3² = 2⋅2³  is true which is the correct answer would be option (C).

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

As per option (A),

39 − 3⋅6 = 6⋅10/4 + 4

39 - 18 = 6 × 5/2 + 4

11 = 30/2 + 4

11 = 15 + 4

11 = 19

This equation is not true.

As per option (B),

8²−5²=4²−7

64 - 25 = 16 - 7

39 = 9

This equation is not true.

As per option (C),

56 ÷ 8 + 3² = 2⋅2³

56 / 8 + 9 = 2 × 8

7 + 9 = 16

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.

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

                                h'(4) = f'(-1) * 8

                                h'(4) = (-2) * 8
