Mr. Cole made this diagram of his bedroom. Which is the area of Mr. Cole’s bedroom? 90 square feet 82 square feet 72 square feet 36 square feet

Answers

Answer 1

Answer:

The answer is 82 square feet

Step-by-step explanation:

An easy way to do this is to split it into two rectanlges. You can do 10*5 and 8*4 as the dimensions to the two rectangles or you can do 2*4 and 9*8.

I am going to do the first option.

The area of a rectangle is length times width.

Rectangle one can be the one with the dimensions 10 and 5 and the length and width.

Rectangle two can be the one with the dimensions 8 and 4 and the length and width.

Area of rectangle one = 50 feet^2

Area of rectangle two = 32 feet^2

Since we split a large irregular shape into two bits, we must add them together, which results in 82 feet^2.

fv=100000, pmt=4000, i/y=5%, n=10, what is pv?

Answers

The Present value is $6,139.132.

We have,

FV=100000, pmt = 4000, I =5%, n=10

So, The present value formula is

PV=FV / (1 + $i)^n$

So, PV = 100, 000 / (1+ 5/100$)^{10\\$

PV = 100,000 / (1+ 0.05$)^{10\\$

PV = 100, 000/ (1.05$)^{10\\$

PV = 100,000 / 1.6288946

PV= $6,139.132

What is an equation of the line that passes through the points (3,6) and (1,−2)?

Answers

Answer:

y = 4x - 6

Step-by-step explanation:

Hi there!

We are given the points (3,6) and (1, -2), and that a line passes through these 2 points

We want to find the equation of said line

There are 3 ways to write the equation of the line:

Slope-intercept form, which is y=mx+b, where m is the slope and b is the y interceptStandard form, which is ax+by=c, where a, b, and c are integer coefficients but a and b cannot be equal to 0, and a cannot be negative Slope-point form, which is $y-y_1=m(x-x_1)$, where m is the slope and $(x_1, y_1)$ is a point

The most common way is slope-intercept form, so let's write the equation of the line this way

First, we need to find the slope

The slope (m) can be found using the formula $\frac{y_2-y_1}{x_2-x_1}$, where $(x_1, y_1)$ & $(x_2, y_2)$ are points

Before we calculate, let's label the values of the points.

$x_1=3\\y_1=6\\x_2=1\\y_2=-2$

Now substitute into the formula

m=$\frac{y_2-y_1}{x_2-x_1}$

m=$\frac{-2-6}{1-3}$

Subtract

m=$\frac{-8}{-2}$

Divide

m= 4

The slope of the line is 4

Substitute 4 as m in y=mx+b:

y = 4x + b

Now to find b

Since the equation passes through both (3,6) and (1, -2), we can use either point to help solve for b.

Taking (3,6) for example:

Substitute 3 as x and 6 as y.

6 = 4(3) + b

Multiply

6 = 12 + b

Subtract 12 from both sides

-6 = b

Substitute -6 as b into the equation

y = 4x - 6

Hope this helps!

A triangle has a base that measures 8 centimeters and a height that measures 10 centimeters. What is the area of the triangle?

Answers

The area of a triangle is given by the following formula:

$A=\frac{b\times h}{2}$

Where b is the length of the base and h is the length of the height of the triangle, in this case, b equals 8 and h equals 10, by replacing these values into the above formula, we get:

$A=\frac{8\times10}{2}=\frac{80}{2}=40$

Then, the area of the triangle equals 40 square centimeters.

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
