A room has an area of 456 square feet. One dimension is 5 feet more than the other. What is the dimensions of the room?

1 answer:

4 0

Draw a rectangle. Label the length x and the width (x+5). A = L*W => x(x+5)=456 => x^2 +5x-456=0 => Solve for x using Quad formula. x=19 and x=-24
So your dimensions are 19 and 24

Answer:

log x² $y^{4}$

Step-by-step explanation:

Using the rules of logarithms

log x + log y ⇔ log xy

log $x^{n}$ ⇔ n log x

Given

2logx + 4logy

= logx² + log $y^{4}$

= log x² $y^{4}$

We read $3\frac{1}{2}$ pages .

Step-by-step explanation:

Correct Question: You have to read 10 1/2 pages for homework. So far, you have read 1/3 of the assignment. How many pages did you read?

We have , to read 10 1/2 pages or $10\frac{1}{2}$ pages for homework . Till now we have read 1/3 of the assignment or $\frac{1}{3}$ of the assignment . We need to find How many pages did you read . Let's find out:

Basically we read 1/3 part of the 10 1/2 pages assignment i.e.

⇒ $10\frac{1}{2}(\frac{1}{3})$

⇒ $\frac{20+1}{2}(\frac{1}{3})$

⇒ $\frac{21}{2}(\frac{1}{3})$

⇒ $\frac{3(7)}{2}(\frac{1}{3})$

⇒ $\frac{7}{2}$

⇒ $3\frac{1}{2}$ pages

Therefore , We read $3\frac{1}{2}$ pages .

For this case, we can model the problem as a triangle with a right angle.
Where,
x, y: lengths of the sides of the triangle
d: hypotenuse of the triangle
We then have the following relationship:
$d ^ 2 = x ^ 2 + y ^ 2
$
Clearing d we have:
$d = \sqrt{ x^2 + y^2}$
Answer:
A functions that would best model the situation above is:
D square root
