This is 60 because if you were to 12 times 1 you would get 12 then multiply by 5 and you get 60. Now to check your answer do 12 divided by 12 which gives you 1 and do 60 divided by 12 gives u 5. Therefore the answer is 60cm hope this helps!

How do you use a number line from least to greatest

Arlecino [84]

Step-by-step explanation:

left to right.

the smallest numbers are on the left, the largest in the right.

all the numbers in the line are sorted.

so, going from left to right the numbers get continuously larger (no exception), and when going from right to left, they get continuously smaller.

remember that the negative numbers are smaller than the positive numbers. so, the negative numbers (if there are any in your case) are on the left side.

and negative numbers get smaller by "seemingly increasing" : -1 is larger than -2 and so on.

so, the range of the negative numbers starts on the left side with the "largest" negative number (but when you think about it, it IS the smallest number) and their absolute value gets smaller until they reach 0, and then the positive numbers start from small to large.

this also asked to fractions and mixed fraction numbers :

e.g. -2 1/2 is smaller than -2 and larger than -3.

because it is -2 + -1/2 = -2 - 1/2 = -2 1/2.

in that sense it is the same principle as with positive numbers :

2 1/2 = 2 + 1/2

-2 1/2 = -2 - 1/2

Answer:

Area is 582 feet squared

Step-by-step explanation:

So, it suggests you break the shape apart, which is exactly what we can do to solve this problem.

We know that the longest side is 38ft, but to find the remaining length of the top, we will subtract 21 from 38.

So: 38ft - 21ft = 17ft

Now we can break the shape. The square will be 21 by 18 ft, and the remaining rectangle shape will be 12 by 17ft.

For the area, we'll start with the square. The formula for area is length times width: A=LW

For the square, we have the length, 21, and the width 18ft. All we have to do is multiply them:

21 * 18 = 378ft. squared

Now we can move on the rectangle, which has a length of 17ft, and width of 12ft.

12 * 17 = 204ft. squared

Last step! We add our areas together to get the entire shape's area. So..

378ft. + 204ft. = 582ft. squared

Good luck :P

which property is illustrated by the following statement? 2(-3/9)=(-3/9)2^? Associative Property of Addition, Commutative Proper

Ratling [72]

Consider the given statement:

$2(\frac{-3}{9}) = (\frac{-3}{9})2$

We have to identify the property used in this statement.

1. Associative Property of Addition: Let a,b and c be three real numbers. This property states that $a+(b+c) = (a+b)+c$ . This property is not used in the given statement.

2. Commutative property of multiplication: Let 'a' and 'b' be two real numbers. This property states that $a \times b = b \times a$ .

In the given statement, $2(\frac{-3}{9}) = (\frac{-3}{9})2$

This statement holds commutative property of multiplication as whether 2 is multiplied to $\frac{-3}{9}$ or $\frac{-3}{9}$ is multiplied to 2, the result is same.

So, Commutative property of multiplication is illustrated in this statement.

3. Inverse property of multiplication: A number 'a' is said to have an inverse ' $\frac{1}{a}$ ' if $a \times \frac{1}{a}=1$ . This property is not used in the given statement.

4. Commutative property of addition: Let 'a' and 'b' be two real numbers. This property states that $a+b = b+a$ . This property is not used in the given statement.
