The pre-tax subtotal was $171.00.

An equation is an expression that shows the relationship between two or more numbers and variables.

Given that:

After-tax total = $1,656.99

Tax rate in the area = 8.396%

The pre-tax price would be 100% and this tax rate is an addition.

Total percent = (100+8.396)% = 108.3%

Consider x be the pre-tax amount.

The total bill=  (after-tax total) = (pre-tax subtotal) + 8.3% · (pre-tax subtotal)

 (after-tax total) = (pre-tax subtotal) 108.3

Divide by the coefficient on the right;

 (pre-tax subtotal) = (after-tax total)/108.3

= $1,656.99/108.3

= $171.00

Therefore, The pre-tax subtotal was $171.00.

The pre-tax amount was $130.

Equation in general form:

The length of the diagonal of the Triangle is 14.86 units

What is Diagonal?

When two polygonal vertices are not on the same edge, a diagonal is a line segment connecting them. Any sloping line is known as a diagonal informally.

Given,

Area of Rectangle = 110square units

Length = 11units

Breadth = ?

Area of Rectangle = length x breadth

Breadth = Area of Rectangle / length

Breadth = 110 / 11

Breadth = 10units

Length of diagonal (Pythagoras Theorem)

H^2 = P^2 + B^2

H^2 = (11)^2 + (10)^2

H^2 = 121 + 100

H^2 = 221

H = [tex]\sqrt{221}[/tex]

H = 14.86 units

Hence, The length of its diagonal is 14.86 units

Given that April has 30 days, Luke used, on average, 20.05 kilowatt-hours of electricity per day during April.

The average is the mean value obtained by dividing the total value of a data set by the number of items.

In this situation, we can divide the total electric bill for April by 30 to obtain the average daily charge.

In addition, we can divide the average charge per day by the cost per kilowatt-hour to obtain the number of kilowatt-hours used per day.

The total electric bill for April = $84.21

The charge per kilowatt-hour (kWh) = $0.14

The number of days in April = 30

The bill per day = $2.807 ($84.21/30)

The kilowatt-hours per day = 20.05 kWh ($2.807/$0.14)

Thus, Luke used an average of 20.05 kilowatt-hours per day in April.

The theorem that justifies that the pair of triangles are congruent is: AAS.

The AAS is known as the angle-angle-side congruence theorem, which justifies why two triangles that have a pair of non-included congruent side and two pairs of corresponding congruent sides.

The diagram shows that the two triangles have two corresponding congruent angels that are marked, and they share a common side, which means they have a pair of non-included congruent sides.

This goes to show that the criterion for proving that the two triangles are congruent by the AAS are already given and known.

Therefore, the triangles are congruent to each other by the AAS congruence theorem.

Note that based on the graph given, the mean is at point B, while the median is also at point B:

The mean is the average of a set of variables in mathematics and statistics. The mean may be calculated in a variety of methods, including the simple arithmetic mean (add the integers and divide the total by the number of occurrences), geometric mean, and harmonic mean.

The median, on the other hand, is the number in the middle of a sorted, ascending or descending list of numbers, and it might be more descriptive of the data set than the average.

For the median:

Given the above definition,  and the fact that we have 14 data points, the median is going to be somewhere between the 7th and 8th data points. By graph analysis, it is easy to see the following:

Answer:

2,500

Step-by-step explanation:

1cm=50km

50cm*50km=2500km

Answer:

2500 km

Step-by-step explanation:

If 1 cm is equal to 50 km, we can multiply the 1 cm by 50 to get 50 cm. In order to do this, we also have to multiply the 50 km (which was equal to the 1 cm) by 50 as well.

50 x 50 = 2500

Whatever we do to one side, we have to do to the other to make it equivalent.

The equation of the line is y = x - 8 which passes through the point  (13,5) with slope 1.

We have to determine the equation of a line that passes through the point (13,5) with slope 1.

The slope of a line is defined as the angle of the line. It is denoted by m

Slope m = (y₂ - y₁)/(x₂ -x₁ )

Let the required line would be as

⇒ y - y₁ = m (x - x₁ )

The required line passes through the point (13, 5)

Here x₁ = 13 and y₁ = 5 and m = 1

Substituting these inputs into the above equation obtains the line equation.

⇒ y - 5 = (1)(x - 13)

⇒ y - 5 = (x - 13)

⇒ y = x - 13 + 5

⇒ y = x - 8

Thus, the equation of the line is y = x - 8 which passes through the point (13,5) with slope 1.
