Using ratios and proportions, the time it takes for both of them to wash both cars is 24 minutes

Proportion is explained majorly based on ratio and fractions. A fraction, represented in the form of a/b, while ratio a:b, then a proportion states that two ratios are equal. The ratio is a way of comparing two quantities of the same kind by using division. The ratio formula for two numbers a and b is given by a:b or a/b. Multiply and dividing each term of a ratio by the same number (non-zero), doesn’t affect the ratio.

When two or more such ratios are equal, they are said to be in proportion.

Answer:

Step-by-step explanation:

t is given that a scuba driver descends in water for 2.8 minutes at a rate of   feet per minute.

Let's assume the descending position as negative.

The position at which the scuba driver will be after 2.8 minutes is :

= -  feet per minute × 2.8 minutes

= - 57.4 feet

Now , he sees a large fish and changes his direction and starts diving ascending at a rate of 25 feet per minute for 2 minutes.

Let's assume the ascending position as positive.

So , The position at which the scuba driver will be after 2 minutes after seeing large fish is :

= 25 × 2

= 50 feet

So , the scuba diver's position relative to sea level after the 4.8 minutes will be :

= -57.4 + 50

= -7.4 feet

This meant Scuba driver is 7.4 feet below sea level.

The compound interest after 7 years is $2701.

What is compound interest?

The interest on savings that is computed on both the initial principal and the interest accrued over time is known as compound interest. Compound interest is computed by multiplying the starting principal amount by one and the annual interest rate raised to the number of compound periods minus one. The final step is to deduct the initial loan principal from the calculated value.

When the amount compounds quarterly, it means that the amount compounds 4 times in a year. i.e., n = 4. We use this fact to derive the quarterly compound interest formula. Thus, the quarterly compound interest formula is:

A = P (1 + r/12)[tex].^{n/12}[/tex]

A = 2100(1+3.6/12)[tex].^{7/12}[/tex]

A=2701

Hence the compound interest after 7 years will be $2701.

The values are given below,

Left Hand Limit i.e.  [tex]\lim_{x \to 1^-} f(x)[/tex] = 3 ,

Right Hand Limit i.e.  [tex]\lim_{x \to 1^+} f(x)[/tex] = 1 ,

Function value at x = 1  [tex]f(1)[/tex] = 1 ,

Left Hand Derivative [tex]\lim_{x \to 1^-} f'(x)[/tex] = -6 and

Right Hand Derivative [tex]\lim_{x \to 1^+} f'(x)[/tex] = -6.

So, the function f(x) is neither continuous nor differentiable at x = 1.

Given, a piecewise function

              3㏑(3 - 2x) + 3                for x < 1

f(x) =

                    -3x² + 4                     for x ≥ 1

Now, for  [tex]\lim_{x \to 1^-} f(x)[/tex] we will consider the function  3㏑(3 - 2x) + 3, as we have to find the Left Hand Limit of the function, at x = 1.

[tex]\lim_{x \to 1}[/tex] 3㏑(3 - 2x) + 3 = 3㏑(3 - 2(1)) + 3

= 3 ㏑(1) + 3

= 0 + 3

= 3

Now, for [tex]\lim_{x \to 1^+} f(x)[/tex] we will consider the function -3x² + 4, as we have to find the Right Hand Limit of the function, at x = 1.

[tex]\lim_{x \to 1}[/tex] -3x² + 4 = -3(1)² + 4

= -3 + 4

= 1

Now, for [tex]f(1)[/tex] we will consider the function -3x² + 4,

[tex]f(1)[/tex] = -3(1)² + 4

= -3 + 4

= 1

Now, for [tex]\lim_{x \to 1^-} f'(x)[/tex] we will consider the derivative of the function

3㏑(3 - 2x) + 3,

[tex]\lim_{x \to 1}[/tex] -6/(3 - 2x) = -6/(3 - 2(1))

= -6

Now, for [tex]\lim_{x \to 1^+} f'(x)[/tex] we will consider the derivative of the function

-3x² + 4,

[tex]\lim_{x \to 1}[/tex] -6x = -6(1)

= -6

So, the function f(x) is neither continuous nor differentiable at x = 1.

Hence,  [tex]\lim_{x \to 1^-} f(x)[/tex] = 3 ,  [tex]\lim_{x \to 1^+} f(x)[/tex] = 1 ,  [tex]f(1)[/tex] = 1 ,  [tex]\lim_{x \to 1^-} f'(x)[/tex] = -6 and  [tex]\lim_{x \to 1^+} f'(x)[/tex] = -6

The function is neither continuous nor differentiable at x = 1.

The error in balancing the equation is that the although the number terms on both sides of the equation are the same, the operation on the 1 on the left is an addition while the operation on the number 1 on the Right Hand Side of the equation is a subtraction

A balanced equation is one in which the values or amounts on both sides of the equation are the same.

The unbalanced equation is presented as follows;

16 ÷ 8 = 16 ÷ 8 - 1

The form balanced equation in the question is; 16 ÷ 8 + 1 = 16 ÷ 8 - 1

The error is that in the balanced equation a 1 was added to the Left Side of the equation, while in the unbalanced equation, the difference between the left and right side of the equation is a subtraction of a 1 from the Right Hand Side of the equation.

The step to correctly balance the unbalanced equation involves the subtraction of a 1 from the Left Hand Side as follows;

The unbalanced equation 16 ÷ 8 = 16 ÷ 8 - 1 can be balanced by applying the addition (or subtraction) property of equality, which states that the when the same quantity is added (or subtracted) from two quantities that are initially equal, the resulting quantities that have a different amount following the addition (or subtraction) will remain equal.

The expression, 16 ÷ 8 and 16 ÷ 8 are the same.

Subtracting the same amount of 1 from both sides will result in two new expressions that are also equal in amount as follows;

16 ÷ 8 = 16 ÷ 8

16 ÷ 8 - 1 = 16 ÷ 8 - 1

The error is therefore in adding rather than subtracting a 1 from the Left Hand Side of the equation to balance the equations.

Step-by-step explanation:

We already know how to represent whole numbers on the number line. Let us consider the image shown, here, the digits 0 and 1 are represented on the number line.

Representation of 0 and 1 on The Number Line

If we divide the number line into two equal parts, as shown in the figure below, what value does that mid-point hold? Half of what the graduation between 0 and 1 holds.

So, the point represents (1-0)/2 = ½

Fraction - Representation Of Fraction On The Number Line

Thus we saw, to represent a fraction on the number line, we need to divide the line segment between two whole numbers into n equal parts where n represents the denominator of the fraction. For example, if we have to represent the fraction 1/5 on the number line, hence, we need to divide the line segment between 0 and 1 into five equal parts, where the first point as shown in the figure represents the fraction 1/5, the second represents 2/5 and so on.

Fraction Representation

We must note that, 0/5 = 0 here and 5/5 = 1.

Here you have seen the representation of proper fraction on the number line. To represent improper fractions, you first convert them into mixed fractions. The same procedure, as shown above, is used with the whole number as the starting point.
