It is 1200 feet. This is a variation of a 5-12-13 triangle. I could use Pythagoras to show what's up

1300^2 = 500^2 + b^2
1690000 = 250000 + b^2
b^2 = 1690000 - 250000
b^2 = 1440000
b = 1200 feet

Make a the subject of a2+b2=c2

Answer:

$a=\sqrt{c^2-b^2$

⇒ $a=\sqrt{(c+b)(c-b)}$ [Factorized form]

Step-by-step explanation:

Given expression:

$a^2+b^2=c^2$

We need to make $a$ the subject.

In order to do that we need to solve the expression for $a$ in terms of $b$ and $c$

We have,

$a^2+b^2=c^2$

Subtracting both sides by $b^2$

$a^2+b^2-b^2=c^2-b^2$

$a^2=c^2-b^2$

Taking square root both sides in order to remove square of $a$

$\sqrt{a^2}=\sqrt{c^2-b^2}$

$a=\sqrt{c^2-b^2$

The difference of squares can be factorized and written as:

$a=\sqrt{(c+b)(c-b)}$ [difference of squares $x^2-y^2=(x+y)(x-y)$ ]

Roland bought a dresser for k dollars. After restoring it, he sold it for 3.1k dollars. Which is another way to describe the cha

xxMikexx [17]

Answer: 210 percent increase

Step-by-step explanation: So w know the starting value is k so we can replace it with 1 dollar

now we know he bought the dresser for 1 dollar and sold it for 3.10 dollars

First we have to subtract the starting value 3.1 - the original value

3.1 - 1 = 2.1

then we have to divide that number by the starting value

2.1 divided by 1 = 2.1

Lastly multiply times 100 to get the percent increase

2.1 x 100 = 210 % increase

A rectangular barn measuring 14 feet b 10 feet is located in one corder of a fenced area. Robert ties his cow to the corner of t

Dennis_Churaev [7]

For this problem you would be solving for the area of 3/4 of a circle with the radius being 24ft. So area of a circle is a= PI R squared so plug in 3.14(24)squared order of operations says to square first so 24 squared is 576. Then PI or 3.14 times 576 equals 1808.64
Now because it is only 3/4 of a circle you wil multiply the answer by 3/4 which is 1,356.48 ft. So the Cow has 1,356.48 Ft of grazing area.

How do you find the mean, median and mode?

algol13

If there is an odd number of data values then the median will be the value in the middle. If there is an even number of data values the median is the mean of the two data values in the middle. For the data set 1, 1, 2, 5, 6, 6, 9 the median is 5. For the data set 1, 1, 2, 6, 6, 9 the median is 4.
The mean is the average of the numbers: a calculated "central" value of a set of numbers. To calculate: Just add up all the numbers, then divide by how many numbers there are.
