The measure of the exterior angle at one base angle of an isosceles triangle is 125 degrees. what is the measure of the vertex angle in degree the measure of the exterior angle at one base angle of an isosceles triangle is 125 degrees. what is the measure of the vertex angle in degrees
Final answer:
To find the measure of the vertex angle in an isosceles triangle, subtract the measure of one of the exterior angles from 180, divide that sum by 2 to find the measure of each base angle, and then subtract one base angle from 180 to find the measure of the vertex angle. In this case, the measure of the vertex angle is 152.5 degrees.
Explanation:
To find the measure of the vertex angle in an isosceles triangle, we can use the fact that the sum of the measures of the interior angles of a triangle is 180 degrees. Since we know that the measure of one of the exterior angles is 125 degrees, we can subtract that from 180 to find the sum of the measures of the other two interior angles. Then, we can divide that sum by 2 to find the measure of each of the base angles. Finally, we subtract the measure of one base angle from 180 to find the measure of the vertex angle.
Let's follow these steps:
Sum of the measures of the other two interior angles = 180 - 125 = 55 degrees
Measure of each base angle = 55 / 2 = 27.5 degrees
Measure of vertex angle = 180 - 27.5 = 152.5 degrees
Therefore, the measure of the vertex angle in this isosceles triangle is 152.5 degrees.

$12.5 money do you save by using the spray gun on a paint job that involves painting 40 m²
What is Equation?Two or more expressions with an Equal sign is called as Equation.
A painter is paid per hour: 11 dollars
Paint with a roller in this time: 8 m²
it takes 1/2 an hour for the painter to clean up after using the roller,
Renting a spray gun costs 5 dollars for each hour of use, and the painter can paint 20 m² per hour with the spray gun.
it takes one hour for the painter to clean up after using the Spray.
We have to calculate how much we have to pay the painter for her time and you must also pay for renting the spray gun for the total amount of time (including clean up) the spray gun was needed. and how much the spray gun on a paint job that involves painting 40 m^2.
Roller
40m²/8m²=5 hrs
5hr to paint with roller.
Total time =5+0.5=5.5hrs
Amount paid=5.5×11=$60.5
40m²/20m²=2 hrs
2 hr to paint with roller.
Total time 2+1=3hr
Amount 3×11+5(3)=$33+15=$48
The saving by using the spray gun on a paint job that involves painting 40 m².
60.5-48=$12.5
Hence $12.5 money do you save by using the spray gun on a paint job that involves painting 40 m²

40 POINTS!!!!! A submarine descends to 1/6 of its maximum depth. Then it descends another 2/3 of its maximum depth. If it is now at 650 feet below sea level, what is its maximum depth? Show your work.
Answer:
The maximum is 780.
Step-by-step explanation:
1/6x+2/3x=650
Which is: 1/6x+4/6x=650
5/6x=650
5/6x÷5/6=650÷5/6
x=650 × 6/5
x= 780
The maximum depth the submarine descends to is; 780 ft
Let the maximum depth be x.It descends to 1/6 of max depth = (1/6)x
It descends another 2/3 of max depth = (2/3)x
After descending the depths above, it is now 650 ft below sea level. Thus;(1/6)x + (2/3)x = 650
x(1/6 + ⅔) = 650
x(5/6) = 650
x = 6 × 650/5
x = 780 ft
In conclusion, the maximum depth is 780 ft.Read more about depth below sea level at; https://brainly.com/question/25823081

Applying the distance formula, the perimeter of the polygon that has the given vertices is calculated as: 32 units.
Recall:
Perimeter of a polygon is the sum of all its sides.Distance between two vertices having coordinates can be calculated using the distance formula given as: [tex]d = \sqrt{(y_2 - y_1)^2 + (x_2 - x_1)^2}[/tex]Assume the vertices of the polygon are named as:
A(3, 2) B(3, 9)C(7, 12)D(11, 9)E(11, 2)Perimeter of the polygon = AB + BC + CD + DE + AE
Find the distance between A(3, 2) and B(3, 9) using the distance formula:[tex]AB = \sqrt{(9 - 2)^2 + (3 - 3)^2}\\\\AB = \sqrt{7^2 + 0^2} \\\\AB = \sqrt{49} \\\\\mathbf{AB = 7}[/tex]
Find the distance between B(3, 9) and C(7, 12) using the distance formula:[tex]BC = \sqrt{(12 - 9)^2 + (7 - 3)^2}\\\\BC = \sqrt{3^2 + 4^2} \\\\BC = \sqrt{25} \\\\\mathbf{BC = 5}[/tex]
Find the distance between C(7, 12) and D(11, 9) using the distance formula:[tex]CD = \sqrt{(9 - 12)^2 + (11 - 7)^2}\\\\CD = \sqrt{-3^2 + 4^2} \\\\CD = \sqrt{25} \\\\\mathbf{CD = 5}[/tex]
Find the distance between D(11, 9) and E(11, 2) using the distance formula:[tex]DE = \sqrt{(2 - 9)^2 + (11 - 11)^2}\\\\DE = \sqrt{-7^2 + 0^2} \\\\DE = \sqrt{49} \\\\\mathbf{DE = 7}[/tex]
Find the distance between A(3, 2) and E(11, 2) using the distance formula:[tex]AE = \sqrt{(2 - 2)^2 + (11 - 3)^2}\\\\AE = \sqrt{0^2 + 8^2} \\\\AE = \sqrt{64} \\\\\mathbf{AE = 8}[/tex]

What are the slope and the y-intercept of the line T=14N+40
Final answer:
The slope of the line represented by T=14N+40 is 14, and the y-intercept is 40.
Explanation:
The equation T=14N+40 is in the form y=ax+b, where a represents the slope and b represents the y-intercept. In this equation, 14 is the coefficient of N (which takes the role of x in the general form), indicating that the slope of the line is 14. The constant term is 40, indicating that the y-intercept is 40.
Is writing a 3 before a square root symbol the same as writing it after a square root symbol?
No, writing a 3 before a square root symbol is not the same as writing it after a square root symbol.
Explanation:No, writing a 3 before a square root symbol is not the same as writing it after a square root symbol. Placing a number before the square root symbol indicates that the number is being multiplied by the square root. For example, 3√x means that the square root is being multiplied by 3. On the other hand, placing a number after the square root symbol indicates that the square root is being taken of that number. For example, √3 means the square root of 3.

Marja bicycled 7 hours a day for 14 days. She traveled 294 miles. What is her unit rate of travel per day?
Marja's unit rate of travel per day is calculated by dividing the total miles she traveled (294 miles) by the number of days she biked (14 days). The result is 21 miles per day.
Explanation:The question asks for the unit rate of Marja's travel per day. Unit rate refers to the amount of quantity per one unit of another quantity. In this case, we want to find out how many miles Marja bicycles in a single day.
To calculate this, we need to take the total miles she traveled (294 miles) and divide it by the total number of days she biked (14 days). So, 294 miles ÷ 14 days = 21 miles/day.
This means Marja's unit rate of travel per day was 21 miles.

The domain is all real numbers from 0 to 500.
Answer:
The domain is the integers from 0 to 500.
Step-by-step explanation:
It is given in the problem "...function that shows the profit as a function of the number of tickets sold"
Here, the independent variable is the number of tickets
Since the auditorium has 500 seats, we can sell a maximum of 500 tickets and a minimum of 0 tickets. There cannot be fractional person, so the domain of the function is all integers from 0 to 500.
The sales tax for an item was $7.40 and it cost $370 before tax. find the sales tax rate. write your answer as a percentage.
The sales tax rate is 2%.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given that, the cost of the item is $370.
Sales tax of item is $7.40.
Let the sales tax is m%.
To find the sales tax in percentage:
Use percentage formula;
7.40 = m x 370 / 100
m = 7.40 x 100 / 370
m = 740 / 370
m = 2
The sales tax is m = 2%.
