Annabelle measured her bedroom as 11 ft times 13 ft, which is 143 square feet. she wants to change the units to square inches. which statements should she consider when converting? check all that apply. there are 12 inches in every foot. the length and width will change by a factor of 1.2 times 10 superscript 1. the length and width will change by a factor of 1.2 times 10 superscript 0. the area will change by a factor of (1.2 times 10 superscript 1 baseline) (1.2 times 10 superscript 1 baseline) = 1.44 times 10 superscript 2 baseline = 144, since area is length times width. the area will change by a factor of 2 (1.2 times 10 superscript 1 baseline) = (2 times 10 superscript 1 baseline) (1.2 times 10 superscript 1 baseline) = 2.4 times 10 superscript 2 baseline = 240, since both the length and width increase by that factor.
Answers
There are 12 inches in every foot and the area will be increased by 144 factors.
We know that the feet and inches are the units of length. One foot is 12 inches.
The length and the breadth are given as 11 feet and 13 feet.
The area of the bedroom is 143 square feet.
We know that 1ft = 12 in
So, The length would become 11 feet to 132 inches.
The breadth would become 13 feet to 156 inches.
What is the formula for the rectangle?The area of the rectangle = length × Width
Therefore, the area of the rectangle = 132 × 156
Since area of the rectangle= 20592 in .sq
The area of the bedroom increased by 144 factors.

Answers
Step-by-step explanation:
just apply the formula you can find immediately on the internet.
that is much faster than putting such a calculation question in here.
the area of a circle is
pi×r²
with r being the radius.
so, in our case we have
pi × 3² = pi × 9 = 28.27433388... ft²
when using 3.14 for pi we get 28.26 ft²

By using properties for exponents, we will see that the equivalent expression is:
[tex]2x^{-4}y^6[/tex]
Which is the equivalent expression?Here you need to remember the property:
[tex]a^n/a^m = a^{n - m}[/tex]
We have the expression:
[tex]\frac{-4x^{-3}y^4}{-2xy^{-2}}[/tex]
We can separate the fraction to:
[tex]\frac{-4x^{-3}y^4}{-2xy^{-2}} = \frac{-4}{-2}*\frac{x^{-3}}{x} *\frac{y^4}{y^{-2}}[/tex]
Now we can simplify by using the above relation, we will get:
[tex]\frac{-4x^{-3}y^4}{-2xy^{-2}} = \frac{-4}{-2}*\frac{x^{-3}}{x} *\frac{y^4}{y^{-2}} = 2*x^{-3-1}*y^{4 - (2)} = 2*x^{-4}*y^6[/tex]

From the given information:
The function f(t) = -16t² +64t + 5 models the height of a ballWhere;

From the table, when t = 0, the function becomes:
f(t) = -16t² +64t + 5
f(t) = -16(0)² + 64(0) + 5
f(t) = 5
Therefore, we can conclude that the best statement that compares the ball is: f(t) is in the air for about 5 seconds, and the ball represented by g(t) is in the air for about 3 seconds.

Is B the expression for the perimeter of the rectangle, in inches?
Answers
Answer:
A, C, D
Step-by-step explanation:
P = 2L + 2W
L = 5W - 2
P = 2(5W - 2) + 2W
P = 10W - 4 + 2W
P = 12W - 4
Answer choices A, C, and D = 12W - 4
I hope this helps!
that can be represented as 5w-2
the equation for perimeter is 2l+2w=p, where l is the length, w is the width, and p is the perimeter
so, plug in the equation we found into the length part of the perimeter equation and leave 2w the same
2(5w-2)+2w
that makes A correct
however, when you distribute the 2, the equation becomes 10w-4+2w
combine like terms to get 12w-4
that would make d also correct
in conclusion, a and d are the correct answers
hope that helps!!
