Find the actual area:

Step-by-step explanation:

5×5×5=125

120÷5=24

Step-by-step explanation:

Answer:

Step-by-step explanation:

Answer:

a) -98

b) -12

c) -105

d) -46

Answer:

There are many answers to this question like:

7x6

21x2

84/2

27+15

Step-by-step explanation:

If 30+12=42, all you really have to do is check each answer to see if it either adds up to 42, multiplies to get 42, divides to get 42, or subtracts to get 42.

Answer:

6(5+2)

3(10+4)

Step-by-step explanation:

These are just a couple of equivalent sums, I am assuming this is a sort of short response and not a multiple choose so i believe you can use this.

Answer:

Step-by-step explanation:

You are to assume in both problems that the two triangles are similar. That is a very dangerous assumption -- especially in later math classes. But in this case, there is no other way to do the problem. The two sets of triangles look like they are proportional.  So set up two ratios that are = to each other

On the left

long side small triange / long side large triangle = base small triangle / base large triangle

On the right

hypotenuse/longest leg = hypotenuse / longest leg.

Problem A

Set up the similar Proportion

5/40 = x/20                Cross Multiply

40x = 20*5

40x = 100                   Divide by 40

x = 100/40

x = 2.5

Problem B

Again set up the similar triangle proportion

15/10 = x/2                  Multiply by 2

15*2/10 = x              

3 = x

you would try all becauseyou all try you are intilligent mare than other

Answer:

I would guess 20%

Step-by-step explanation:

16+30+34)/4)x5   (this is how I think u would get it to be 100)

16/4)x5 = 20

20/100 = 20%

Im less certian about this one than the other but if u think its correct u can try it

Circle question of the rug

That you needed answer for is ;

3/4 pi^2  

Step-by-step explanation:

Proof  1/4 pi r^2

We can state the radius of small rug is 3ft

to show Area pi 3^2 = pi 9

If the large rug is 3x this size  

then  pi 9^2 = pi81

So the ratio here is 1 : 9 when 3 cm or 1 : 3 radius

Ratio is 1 : 9 when 1cm or 1 : 3 radius  

When 1 : 9 cm when 5cm or 1 : 3 radius  

So if we are considering an expression of the larger rug  

that shows 3: 1 more radius to that of the small.

1/4 pi^2 becomes 3/4 pi^2 of the smaller rug

As this is 3 x 1/4 pi^2 we show 3/4pi r^2

Two "factors" are multiplies together to product another number (the product).  So, for example, the prime factors of 10 are 2 and 5.  Prime factors that, themselves, have only factors of 1 and themselves.  Non-prime numbers, like 10, have prime factors.  Note that 1 is a factor of all integers.

If the two factors are equal (the same), like 4*4=16, then each of them is called a "square root."

Note: a cube root is one of three equal factors of a number, for example, 2 is the cube root of 8 (that is, 2*2*2=8).

Practice:

   What is the square root of 49?

   What is the square root of 100?

   What is the square root of 625?

   Memorize the squares of the numbers from 1 to 10, or 1 to 20  -- that will be very helpful in math classes.

Step-by-step explanation:

Answer:

Step-by-step explanation:

-3, -2, 2, 3

Answer:

a) -42

b) -23

c) -100

d) 45

Answer:

a) | -29 - 13 | = 42

b) | 39 - 62 | = 23

c) | -59 - 41 | = 100

d) | -26 + 71 | = 45

Remember, absolute value refers to a number's distance from zero on the number line, without taking direction into account. A number's absolute value can never be negative.

Hope this helped! :)

Answer:

409

Step-by-step explanation:

This is very easy. First of all you need to workout out 1/10 of the value of the 9 in 296. The value of the 9 in 296 is 90.

1/10 of 90 is 9 (since 1/10 x 90 = 90/10 = 9)

The only number which has 9 as its final digit is 409

Answer:

7

Step-by-step explanation:

Answer:

The answer is 14.

Step-by-step explanation:

All you have to do to figure this problem out is to divide 42 by 3. I hope this helps! :)

Answer:

([tex]n^{2}[/tex]+4)-3

Step-by-step explanation:

since it says "and four" i think it means it is in parenthesis

Answer:

n^2 + 1

Step-by-step explanation:

Let the unknown number be n.  Then "a number squared and four" is

n^2 + 4, and 3 fewer than this result is

n^2 + 3 - 3, or n^2 + 1
