The first figure is a rectangle. Rectangles are known for having four right angles. Thus, one of the angles in this figure is 90 degrees.

The second figure is an equilateral triangle. Because all its sides have the same length, the angles are all the same. There is a principle stating that the sum of the 3 interior angles of a triangle is 180 degrees. Thus, the measure of one of these 3 angles is 180 degrees / 3 = 60 degrees.

P=m/1+rt solve for t

blagie [28]

I assume you mean:

P=m/(1+rt) multiply both sides by (1+rt)

P(1+rt)=m perform indicated multiplication on left side

P+Prt=m subtract P from both sides

Prt=m-P divide both sides by Pr

t=(m-P)/(Pr)

<h3>What is a Function ?</h3>

A function is a mathematical statement used to relate a dependent and an independent variable.

It is given that

Total time taken to hike is 8 hours

Let the time taken in hours is represented by t

and the elevation is represented by h

Every hour, the hikers gain 250 feet in elevation.

The independent variable is t , time taken to hike , in hours .

The dependent variable is h , increased elevation in feet or elevation the hikers have gained .

A possible verbal description is Elevation at any given time equals 250 times the time taken to hike.

The equation h = 250 t corresponds to the relationship.

Solve for x A:10 B:14.5 C:20 D:6÷3

den301095 [7]

By applying Cathetus theorem, the value of x is equal to 10 units.

<h3>How to determine the value of x?</h3>

In order to determine the value of x, we would apply Cathetus theorem (leg rule), which states that each leg of a right-angled triangle is the geometric mean that's directly proportional between the hypotenuse and the part of the hypotenuse that's directly below the leg.

In this context, we have:

x² = m × a

x² = (21 + 4) × 4

x² = 25 × 4

x² = 100

x = √100

x = 10 units.

A model house that runs completely on renewable energy uses 2 windmills and 3 solar panels each windmill generates M kilowatt ho

kozerog [31]

Answer:

y=(20M+30S) kwh

Step-by-step explanation:

Since each windmill generates M kwh then for ywo windmills, each year they will generate 2 M kilowatt hours

For solar panels, since each generates S kilowatts annually then for 3 of them, the power will be 3 S

Total production per year will be 2M+3S

In n years, the energy will be y(n)=(2M+3S)n

When n is 10 years then

y(10)=(2M+3S)10=20M+30S

Therefore, y=(20M+30S)kwh
