Answer:

1. area = LW if area = 5432 then you divide 5432/97 and get the width Answer is =56

Step-by-step explanation:

2. Perimiter is 2L+2W so you would do

336 = 2L + 79 times 2

336 = 2L + 158

336- 158 = 178

178/2 = 89

the length is 89cm

Answer:

56 m

Step-by-step explanation:

The area of a rectangle is found by multiplying length by width. since we already know the length, then we can just divide the total area by the length to find the width.

5432/97 = 56

and to check our work, make sure to multiply length by width.

97 * 56 = 5432

Answer: Choice B

$\left\{ \ 3, 5, \sqrt{34} \ \right\}$

=========================================================

Explanation:

We'll be using the converse of the pythagorean theorem.

If we had a triangle with sides a,b,c and $a^2+b^2 = c^2$ was true, then we have a right triangle. Note: c is always the longest side

For the first answer choice we have: a = 5, b = 8, c = 12

Then,

$a^2+b^2 = c^2\\\\5^2+8^2 = 12^2\\\\25+64 = 144\\\\89 = 144\\\\$

which is false. This shows that we do not have a right triangle with sides 5,8,12. This rules out choice A. Choice C is a similar story.

Choice B on the other hand works because

$a^2+b^2 = c^2\\\\3^2+5^2 = (\sqrt{34})^2\\\\9+25 = 34\\\\34 = 34\\\\$

We have a true statement at the end, which confirms <u>choice B</u> is a right triangle.

Answer:

m = 13.

Step-by-step explanation:

Recall that adding logarithmic equations, (ex: log a + log b) is the same as log (a·b). Therefore:

log 12 + log 5 = log (4m + 8)

log (12·5) = log (4m + 8)

log (60) = log (4m + 8) **Ignore 'Log' to solve for 'm'

60 = 4m + 8 **Subtract both sides by 8

52 = 4m **Divide both sides by 4

m = 13.

Lerok [7]

Answer:

$9*10^{12}km$

Step-by-step explanation:

$9,460,730,472,580.8 km$

First, we can work out 5% of our number, by multiplying it by 0.05

$9,460,730,472,580.8 * 0.05 = 473,036,523,629$

Now, if we add and subtract our 5% calculated from our original number, we can work out the minimum and maximum value that our final answer can be in the range of.

$9,460,730,472,580.8 + 473,036,523,629 = 9.933767*10^{12}\\9,460,730,472,580.8 - 473,036,523,629 =8.98769395*10^{12}$

We can see that $9*10^{12}$ is in the range of valid answers, as:

$8.9*10^{12} \leq 9*10^{12} \leq 9.9 * 10^{12}$

So, our final answer is:

$9*10^{12}km$
