First of all, you need to know how to find the area of a rectangle.
The area of a rectangle is (the length) multiplied by (the width).
You know that the length is 48 inches, and the width is 24 inches.
But before you run off and multiply those, look at the question again.
It asks for the area "... in square feet". If you just go and multiply
the (48 inches) by the (24 inches), you'll have the area in square inches.
You could do that, and then change square inches to square feet, but
I'm guessing that you don't know how to do that. So what will you do ?
Why not change the measurements to feet BEFORE you multiply them ? ! ?
You know that 1 foot is the same as 12 inches, right ?
So, 48 inches = 4 feet, and 24 inches is 2 feet.
The poster is 4-ft long by 2-ft wide. Multiply those: (4-ft) x (2-ft) = <u>8 square feet</u>.
Is that neat or what !
In the context of rubiks cube solving the rate at which one can solve a rubiks cube is determined by the number of cubes solved and the time taken
In this question we were told that moira solved a rubiks cube in 3 minutes 30 seconds
Let us convert time total time to seconds
3 minutes 30 in seconds = 3*60+ 30 = 180+30 = 210 seconds
Hence Moira rate = 1 rubiks cube/210 seconds

Answer:
Step-by-step explanation:
Given:
Linear transformation,
defined as
To Show: T is invertible
To find:
We know that Standard Basis of R² is
So, The matrix representation of T is
Now, Determinant of T = 1 - (-1) = 1 + 1 = 2 ≠ 0
⇒ Matrix Representation of T is Invertible matrix.
⇒ T is invertible Linear Transformation.
Hence Proved.
let,
Add (1) and (2),
Putting this value in (1),
Now,
Therefore,
Answer:
where are they
Step-by-step explanation:
seriously where are the questions
Answer:
Fraction = 13/20
Decimal = 0.65
Percent = 65%
Step-by-step explanation:
<em><u>Given:</u></em>
13 out of 20 emails in mail inbox are junk emails
<em><u>Solve for:</u></em>
The experimental probability that next email is junk
<em><u>Solution:</u></em>
Step 1: Define the formula for calculating the probability
P = number of elements/total number of elements
Step 2: Perform the calculation
The number of elements (junk emails) = 13
The total number of elements (all emails) = 20
=> P(obtain odd number in experiment) in fraction form = 13/20
=> P(obtain odd number in experiment) in decimal from = 0.65
=> P(obtain odd number in experiment) in percent form = 0.65 x 100 = 65%
Hope this helps!
