What is median of a triangle Class 7?
A triangle's median is a straight path that joins a vertices to the midpoint of the following sectors across from it.
A triangle is a three-sided polygon that consists of three vertices, three sides, and three angles. Three types of triangles—scalene, isosceles, and equilateral—can be distinguished based on the length of their sides.
It can be an acute-angled, obtuse-angled, or right-angled triangle depending on the size of its angles. A triangle's internal angles add up to 180 degrees. Two more terms—altitude and triangle median—are introduced to you in this essay.

A family wants to rent a car to go on vacation. Company A charges $55.50 and 15¢ per mile. Company B
charges $50.50 and 9¢ per mile. How much more does Company A charge for x miles than Company B?
Company A charges $5.00 and 6 cents much more for x miles than Company B. The solution is obtained using arithmetic operations.
What are arithmetic operations?There are four basic operations which are listed as follows: Addition(‘+’): This operation deals with finding the sum. Subtraction(‘-’): This operation deals with finding the difference. Multiplication(‘×’): This operation deals with finding the product. Division(‘÷’): This operation deals with finding the quotient.
In order to find how much more does company A charge than company B, we need to subtract the charges of company B from that of Company A.
So, on subtracting we get,
$55.50 and 15 cents - $50.50 and 9 cents = $5.00 and 6 cents per mile.
For x miles, we multiply $5.00 and 6 cents by x miles.
Also, we could convert dollars to cents by multiplying it by 100.
as $1 =100 cents.
5565 - 5059 cents = 506 cents.
For x miles, 506x cents.
Hence, Company A charges $5.00 and 6 cents much more for x miles than Company B.

find each measure using the information given
G is the incenter of ABC
a)GD
b)BG
c)FC
d)BF
if possible can you show the equation break down if some are needed
If G is the incenter of triangle ABC the values of the unknown sides are
a) GD = 12
b) BG = 13.42
c) FC = 35
d) BF = 6
How to find the unknown dimensions
Considering that G is the incenter of triangle ABC, we have that
GE = GD = GFUsing the right triangle CDG and applying Pythagoras theorem given by the formula
hypotenuse² = opposite² + adjacent²
plugging the values as in the problem
GC² = GD² + DC²
37² = GD² + 35²
GD² = 37² - 35²
GD² = 144
take square root of both sides
GD = √144
GD = 12
Using the right triangle BEG to solve for BG
BG² = EB² + GE²
BG² = 6² + 12²
BG² = 180
take square root of both sides
BG = √180
BG = 13.42
Using the right triangle CFG to solve for FC
GC² = GF² + FC²
rearranging the equation
FC² = GC² - GF²
FC² = 37² - 12²
FC² = 1225
take square root of both sides
FC = √1225
FC = 35
Using the right triangle BFG to solve for BF
BG² = GF² + BF²
rearranging the equation
BF² = BG² - GF²
BF² = 13.42² - 12²
BF² = 36.0964
take square root of both sides
BF = √36.0964
BF = 6

Suppose your family is going to buy a new air conditioning unit. A more expensive brand cost $2600 to buy but only $50 a month to operate. Let “x” represent time in months.
a. write an equation for the cost of the cheaper brand
b. Write an equation for the cost of the more expensive brand.
c. What is the cost of running the cheaper unit for 36 months?
d. For how many months will the cost of both brands be equal?
An equation for the cost of the cheaper brand is y = 60x + 1,800.
An equation for the cost of the more expensive brand is y = 50x + 2,600.
The cost of running the cheaper unit for 36 months is $3,960.
The number of months for which the cost of both brands would be equal is 8 months.
How to write an equation to model this situation?In order to write an equation that model this situation, we would assign variables to the time and cost respectively, and then translate the word problem into algebraic equation as follows:
Let the variable x represent the time measured in months.Let the variable y represent the cost measured in dollars.Since a brand cost $1800 to buy with a monthly operation fee of $60, an equation for the cost of this cheaper brand is given by:
y = 60x + 1,800.
When x = 36 months, the cost of running the cheaper unit is given by:
y = 60(36) + 1,800.
y = $3,960.
For the more expensive brand, we have:
y = 50x + 2,600.
Next, we would determine the number of months for which the cost of both brands would be equal;
50x + 2,600 = 60x + 1,800
60x - 50x = 2,600 - 1,800
10x = 800
x = 800/10
x = 8 months.

Therefore ,as a result, the solution of the given problem of equation is left side of the line's run is taken into consideration because the slope is positive.
Describe equation.A mathematical equation is a formula that joins two statements and uses the equal symbol (=) to indicate equality. A scientific statement that verifies the equality of two formalisms is known as an equation in algebra. For instance, the pieces ptdc + 6 and 12 are separated by an equal sign in the solution obd + 6 = 12. The relationship between the two variable on either flank of a letter is described by a mathematical formula. Often, there is only one variable, which also serves as the symbol. for instance, 4x – 4 = 0.

A =
Answer:
A = 1/2b^2 + 3b
Step-by-step explanation:
If the height of the triangle is 6 units longer than the base length, we can represent the height with the variable h and the base length with the variable b.
h = b + 6
We can substitute h with b+6 in the formula for the area of the triangle:

The amount of eric investment would be $ 6290.
What is meant by compound interest?Investors benefit from compound interest, although the term "investors" can indicate many different things. For instance, banks profit from compound interest when they make loans and then reinvest the interest they earn to make more loans. When holders of deposits receive interest on their bank accounts, bonds, or other investments, they also profit from compound interest.
The concept of compound interest applies outside of contexts where the phrase is normally employed, such as bank accounts and loans, despite the fact that the term compound interest includes the word interest.
Let the rate of interest be 2.16 % per year
Time n = 5 years
Amount A = $6999.31
A = P(1 + R/100)ⁿ
substitute the values in the above equation, we get
⇒ 6999.31 = P (1 + 2.16/100)⁵

The metal bar would displace 0.018 liters of water.
Volume is the measure of the amount of space occupied by an object or substance. It is often represented by the symbol 'V' and is typically measured in units such as liters (L), cubic meters (m^3), or gallons (gal). In three-dimensional space, the volume of an object is calculated by multiplying its length, width, and height (or depth). In two-dimensional space, the area of an object can be calculated by multiplying its length and width.
The volume of the metal bar is 3 cm x 3 cm x 2 cm = 18 [tex]cm^3[/tex]. The density of water is 1 g/[tex]cm^3[/tex]. To find the volume of water displaced, we need to convert the volume of the bar from cubic centimeters to liters.
1L = 1000[tex]cm^3[/tex]
So the volume of water displaced would be 18 [tex]cm^3[/tex] / 1000 = 0.018 L.

What is point of intersection?They are referred to be intersecting lines when two or more lines in a plane cross each other. The point of intersection, which can be found on all intersecting lines, is the common point shared by the intersecting lines.
Given that WY intersects UV at Y.
