I believe the perimeter would be 12cm

If it is a square, all the side lengths should be the same. This being the case, it would be 3+3+3+3 or 3(4) which are both 12

Please correct me if I am wrong, have a good day!

Anybody, please answer this for me. I'm not good at mathematics

Well, its kind of obivious that 2x + 4 stands out, but I think you are asking why. Whereas all other lines shown are vertical or horizontal, 2x+4 is diagonal.

A 15 foot flagpole casts an 11 foot shadow. At the exact same time a 28 foot tree casts a shadow. Which proportion would correct

marishachu [46]

The longer an object, the longer the shadow they cast at a given time of the day and vice versa. This is called direct proportionality. At the same time,

If 15 foot flagpole ---- casts 11 foot shandow
28 foot tree -------- casts ?? foot shadow

The proportion would therefore be:

Length of shadow cast by tree = (28/15)*11 = 20.533 foot.

At her birthday party, marcie's guests ate 2/3 of her birthday cake and her family ate 1/4 of the cake. How much cake was left a

Verdich [7]

Answer:

1/12

Step-by-step explanation:

So you start with an equation. 2/3 plus 1/4= ?.

Step 1: Find a common donominator.

Count by each number until they meat up.

3 6 9 12

4 8 12

Step 2: Multiply.

Basically, make sure that if you do something to the bottom you do the same to the top. You have

$\frac{2}{3}$ = $\frac{?}{12}$ . 3 times 4 is 12. 2 times 4 is 8. Your new fraction is $\frac{8}{12}$ .

$\frac{1}{4}$ = $\frac{?}{12}$ . 4 times 3 is 12. 1 times 3 is 3. Your new fraction is $\frac{3}{12}$ .

Step 3: Just Add!

$\frac{8}{12} + \frac{3}{12}= \frac{11}{12}$

Step 4: Answer the question! The question asks "How much cake is left. You know that a whole cake is $\frac{12}{12}$ . So, $\frac{12}{12} -\frac{11}{12} = \frac{1}{12}$

What’s the quotient of 5/31 divides by 15/21

Pavlova-9 [17]

Quotient just means the answer when dividing, so let's divide!:
$\frac{5}{31} / \frac{15}{21} = \frac{5}{31}* \frac{21}{15}$
$\frac{105}{465}$

Simplify (they are both divisible by 15):
$\frac{7}{31}$

And there ya go!
