PLEASE help me...Suck at math. find the following using the given triangle.

Ulleksa [173]

To find the perimeter just add the sides

5+5+6 = 16

To find the area, you need to use the following formula

$area = \frac{1}{2}bh$
we know b but we need to find the height. We can find the heigh by using pythagorean theorem $a^2 + b^2 = c^2$

height = $a^2 + 3^2 = 5^2$
$a^2 + 9 = 25$
$a^2 = 25 - 9$
$a^2 = 16$
$a = \sqrt{16} = 4$
h = height = 4

$area = \frac{1}{2}\times 6\times 4 = 12cm^2$

Cost:

6.00 per cm^2 = 6.00 x 12 = $72.00 dollars

How do I round 3.047 to the nearest hundred and show the math

goblinko [34]

The second place to the right after the decimal is the hundredth, so basically, to round, you cut off the rest of the decimal places afterwards. If the number after the hundredth is at or above 5, you should make the hundredth 1 higher, but if it is 4 or below, you will just leave it as is. In this case, 3.047 rounds to 3.05. There really is not any math work to show, but just the explanation.

97) If the average of 3a and 4b is less than 50 and a is twice b, what

oee [108]

The average of $3a$ and $2b$ satisfies

$\dfrac{3a+4b}2$

Then

$a=2b\implies\dfrac{3(2b)+4b}2=5b$

$a=2b$ , so if $a$ must be an integer, then the largest integer value it can take on is 19 if $b$ can be a rational number (in which case $b=9.5$ ) or 18 if $b$ must also be an integer.

Given that none of the provided answer choices lists 18 or 19, I'd bet there's a typo and you're supposed to find the maximum integer value of $b$ , in which case the answer would be B as the largest integer value would be 9.
