Answer:

Each side is 4 cm.

Step-by-step explanation:

We need to try to express the perimeter of the figure in terms of "square sides". Basically, we're going to count how many square sides the perimeter is.

Starting from the top, the very top is 1 side.

Moving down to the right, we have another side.

Then half a side as we go to the right edge.

The right edge is 1 full side.

Another half side, going left.

Going down, we have 1 full side.

The other side is mirrored, meaning we just have to double this to get the full figure's perimiter.

Counting up our sides (we'll call one side s ), we have:

1s + 1s + 0.5s + 1s + 0.5s + 1s = 4s + 0.5s + 0.5s = 5s

Doubling it:

5s * 2 = 10s

The whole perimiter is 8 square sides. Since we know the perimeter is 40 cm, we can find the length of one side by solving this equation:

10s = 40

Dividing both sides by 10:

s = 40/10 = 4

Answer: Each side is 4 cm.

What is the sum of all positive integers less than 300 which are divisible by 3
drek231 [11]

Answer:

14,850

Step-by-step explanation:

You need the sum of

3 + 6 + 9 + 12 + ... + 294 + 297

Factor out a 3 from the sum

3 + 6 + 9 + 12 + ... + 294 + 297 = 3(1 + 2 + 3 + 4 + ... + 98 + 99)

You need to add all integers from 1 to 99 and multiply by 3.

The sum of all consecutive integers from 1 to n is:

[n(n + 1)]/2

The sum of all consecutive integers from 1 to 99 is

[99(99 + 1)]/2

The sum you need is 3 * [99(99 + 1)]/2

3 + 6 + 9 + 12 + ... + 294 + 297 =

= 3 * [99(99 + 1)]/2

= 3 * [99(100)]/2

= 3 * 9900/2

= 14,850

"What is the probability of drawing a jack or queen from a standard deck of cards?"
Natasha2012 [34]
Well, there are 52 cards in a deck, with 4 suits. there is a Jack and queen per suit, so that is a total of 8 jacks and queens in the deck. that probability looks like 8:52 as a ratio, or 2:13 simplified. so, you are likely to draw a Jack or queen 8 out of 52 times, or 2 out of 13 times

What is the function rule of (1,30) (2,35) (3,40) (4,45)?
stepan [7]
\bf \begin{array}{ccll}
x&y\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
1&30\\
2&35\\
3&40\\
4&45\\
a&5(a)+25
\end{array}\qquad \qquad y=5x+25

if you have already covered slopes, you could also get it that way, in fact is  simpler that way.
