The surface area of a triangular prism can be found by the formula SA = 2(Ab) + Ph. The volume can be found by V = Ab × h.

We have,

to find the volume and surface area of a triangular prism:

To calculate the surface area of a triangular prism, one must sum the areas of all its faces. This can be done by computing the area for each component of the prism and then combining them; utilizing the formulas:

SA = 2(Ab) + Ph

Where SA stands for Surface Area, Ab is the Area of the base (triangle), P representing the Perimeter of the base (triangle) and h denoting the Height of the triangular prism.

Moreover, to ascertain the volume of a triangular prism, the equation is:

V = Ab × h

in which V stands for Volume, Ab is still the Area of the triangular base and h is representing the Height of the triangle that comprises the prism.

Since, the father is 30 years older than his son. Then, the son's age is 10 years old. Therefore, the father's age is x+30 = 40 years old.

Let's denote the son's current age as S and the father's current age as F. From the information given, we know:

1. F = S + 30 (the father is 30 years older than his son)
2. F + 5 = 3 * (S + 5) (the father will be three times as old as his son in 5 years)

Now, we need to solve for F:

Step 1: Substitute the first equation with the second equation:
(S + 30) + 5 = 3 * (S + 5)

Step 2: Simplify the equation:
S + 35 = 3S + 15

Step 3: Move all terms with S to one side and constants to the other side:
35 - 15 = 3S - S
20 = 2S

Step 4: Divide by 2 to isolate S:
S = 10

Now that we know the son's age, we can find the father's age using the first equation:

F = S + 30
F = 10 + 30
F = 40

The father's present age is 40 years old.

Answer:

-5/3

Step-by-step explanation:

The slope of a line passing through two points (x1,y1) and (x2,y2) can be calculated using the formula:

slope = (y2 - y1) / (x2 - x1)

Using the given points (8,1) and (2,-9), we can substitute the values into the formula:

slope = (-9 - 1) / (2 - 8)

slope = -10 / -6

We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which is 2:

slope = (-10 / 2) / (-6 / 2)

slope = -5 / 3

Therefore, the slope of the line passing through the points (8,1) and (2,-9) is -5/3.

Step-by-step explanation:

x - 3 = 3 - x

Therefore, there are 2 observations below the median that is $713 and $825.

To find the median of a data set, we first need to arrange the values in order from smallest to largest. Once the values are in order, we can determine the middle value of the data set. If the data set has an odd number of values, then the median is the middle value. If the data set has an even number of values, then the median is the average of the two middle values. Once we have found the median, we can count the number of observations that are below the median by comparing each observation to the median. If the observation is less than the median, then it is considered to be below the median. First, we need to find the median of the data set. To do so, we can arrange the values in order from smallest to largest:

$713, $825, $919, $1,008, $1,028, $1,041

The median is the middle value, which is $973.

Next, we count the number of observations that are below the median, which are:

The state income tax owed on a $70,000 per year salary is $ $3,684.

To compute the state income tax payable on a $70,000 per year wage, we must first estimate how much of the salary falls into each progressive tax band and then calculate the tax owed for each range.

The first $2,000 in earnings is taxed at 2%:

This portion's tax = $2,000 x 0.02 = $40

The following $7,000 in earnings (from $2,001 to $9,000) is taxed at 5%:

This portion's tax = $7,000 x 0.05 = $350

The remainder of your income beyond $9,000 is taxed at 5.4%:

This portion's tax = ($70,000 - $9,000) x 0.054

= $61,000  x 0.054

= $ 3294

Now, the total amount of tax owed = 40 + 350 + 3294

For a catering company, which used the linear function for calculating the total cost of parties, the cost to cater a dinner party with 90 guests is equals to the $42750.

We have a table form data of total cost of parties for a catering company. There is use of linear function to determine total cost of parties. Table look like as below,

Cost for dinner parties | number of guests

(each guest)

$315 30

$555 60

We have to determine the cost to cater a dinner party with 90 guests. For this we use simple multiplication arithmetic method. As we see in table, cost of cater a dinner party with 30 guests = $315 for each , that is cost for one guest = $315

so, cost of cater a dinner party with 30 guests = 30 × $315 = $ 9450

Similarly, when number of guests is 60 in count, cost of cater a dinner party = $555 for each one

So, total cost of cater a dinner party with 60 guests = 60× $555 = $ 33300

Now, we have total guest = 90

The cost to cater a dinner party with 90 guests

= cost to cater a dinner party with 30 guests + cost to cater a dinner party with 60 guests = $9450+ $33300

= $42750

The ratio of the areas is 4:7.

If two trapezoids are similar, then their corresponding sides are proportional. The ratio of the corresponding diagonal is given as 1:7, so let us assume that the ratio of the corresponding bases is also 1:7.

Let the bases of the trapezoids be a and 7a, and let the heights be h1 and h2 respectively. We can use the formula for the area of a trapezoid, which is:

Area = (1/2) × (sum of bases) × height

The area of the larger trapezoid is:

A2 = (1/2) × (a + 7a) × h2 = 4a × h2

The area of the smaller trapezoid is:

A1 = (1/2) × (a + 7a) × h1 = 4a × h1

We know that the corresponding diagonal is in the ratio of 1:7, which means that the corresponding sides are also in the ratio of 1:7. This implies that the corresponding heights are in the same ratio, i.e., h1:h2 = 1:7.

Therefore, we can write h1 = (1/7)h2. Substituting this into the expression for A1, we get:

A1 = 4a × h1 = 4a × (1/7)h2 = (4/7)A2

So the ratio of the areas of the smaller trapezoid to the larger trapezoid is:

A1 : A2 = (4/7) : 1

Answer:

$25,000

Step-by-step explanation:

To calculate the original amount of the student loan that Scott took, we can use the formula for calculating simple interest:

Simple Interest = Principal (loan amount) x Rate x Time

Given:

Interest (I) = $750

Rate (R) = 3% or 0.03 (as a decimal)

Let's assume the time (T) for the loan is one year, as the rate is given as an annual rate.

Plugging in the values into the formula:

750 = Principal x 0.03 x 1

750 = 0.03 Principal

To solve for Principal, we can divide both sides of the equation by 0.03:

Principal = 750 / 0.03

Principal = $25,000

So, the original amount of the student loan that Scott took was $25,000.
