Answer:

46 in x 28 in = 1288 in^2

Step-by-step explanation:

First you would have to find the height and the width. Then you would have to times the height time width with the height is 28 in and the width is 48 in then you just have to multiply the witch you then turn out with 1288 and you just put the in^2 at the end so your answer is 1288 in^2.

two square regions have an area of 125 and 5 how many yards of fencing is needed to enclose? ( assume regions fenced separately)

nadya68 [22]

Answer:

$24\sqrt{5}\ yards$

Step-by-step explanation:

Let A1 be the area of one square and A2 be the area of second square

So,

A1 = s^2

where s is side of square

$s^2=125\\\sqrt{s^2}=\sqrt{125}\\s=\sqrt{25*5}\\ s= \sqrt{5^2 * 5}\\ s= 5\sqrt{5}$

So side of one square is $5\sqrt{5}$

To calculate the length of fence we need to find the perimeter of the square

So,

P1 = 4 * s

$=4*5\sqrt{5} \\=20\sqrt{5}$

For second square:

$A_2=s^2\\5=s^2\\\sqrt{s^2}=5\\{s}=\sqrt{5}$

The perimeter will be:

$P_2 = 4*s\\=4 * \sqrt{5} \\=4\sqrt{5}$

So the total fence will be: P1+P2

$= 20\sqrt{5}+4\sqrt{5} \\= 24\sqrt{5}\ yards$

The expression 53.7124×103 as a single number

riadik2000 [5.3K]

Answer:

53712.4

Step-by-step explanation:

$53.7124 * 10^{3}$ This is the scientific notation, and since we do not have a negative exponent, we can assume that the decimal is going to move to the right, because when it's negative, the decimal will move to the left, making a smaller number.

So, when we move the decimal 3 times to the right, we find it sitting at 53712.4
