36:20, or 36/20. To simplify, find a number both 36 and 20 can be divided by.
36: 1, 2, 3, 4, 6, 9, 12, 36
20: 1, 2, 4, 5, 10, 20
The largest number both have in common is 4. So, divide both 36 and 20 by 4 so that you have:
9:5

You are buying an area rug for your bedroom. The area of your room you want to cover is 40 feet squared. You find that the lengt

Kamila [148]

The length and the width of the rug having an area of 40 square feet will be 5 feet and 8 feet respectively.

Area is defined as the space covered by any object in the two dimensional plane. Here it is given that the area of the rug should be 40 square feet and the length of the rug is 3 less then its width.

So to find out the length and the width we will form an equation.

Let the width is = x feet

So the length will be = x-3 feet

Now the area will be

$x(x-3)=40$

$x^2-3x-40=0$

By solving the quadratic equation

$x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}$

$x=\dfrac{-(-3)\pm\sqrt{9+(4\times1\times40}}{2}$

$x=\dfrac{3\pm13}{2}$

$x=8 \ and \ \ x=-5.5$

Here the value of x will be positive because length cant be negative.

So the width of the rug will be x=8 feet

Length of the rug will be x-3= 8-3=5 feet

Hence the length and the width of the rug having an area of 40 square feet will be 5 feet and 8 feet respectively.

Please help me find the greatest common factor for these 2 problems..

Kisachek [45]

A greatest common factor is the largest number that goes into two or more numbers (in this case two). To find the GCF of two numbers, we have to find the prime factorization (how to express a number as a product of prime numbers) and then see which numbers are common in both of the prime factorizations.

11. The prime factorization of 12 is 3 * 2 * 2. The prime factorization of 18 is 3 * 3 * 2. Looking at the prime factorizations, we can see that both of them have 3 and 2. That means that the GCF is 3 * 2 which is 6.

12. The prime factorization of 48 is 2 * 2 * 2 * 2 * 3. The prime factorization of 80 is 2 * 2 * 2 * 2 * 5. We see that the numbers shared are 2, 2, 2, and 2. That means that the GCF is 2 * 2 * 2 * 2 or 16.

Please help me solve this,

tiny-mole [99]

$\cos^2\theta=1-\sin^2\theta$

$2\cos^2\theta=\sin\theta+1$
$2-2\sin^2\theta=\sin\theta+1$
$2\sin^2\theta+\sin\theta-1=0$
$(2\sin\theta-1)(\sin\theta+1)=0$

$2\sin\theta-1=0\implies \sin\theta=\dfrac12\implies\theta=\dfrac\pi6,\dfrac{5\pi}6$
$\sin\theta+1=0\implies\sin\theta=-1\implies\theta=\dfrac{3\pi}2$

Answer:

214 books

Step-by-step explanation:

136-58= 78 books in the second box

so to find the total you add the amount of books in the first box with the amount of books in the second to = 214
