The model shows the expression 30 +12. Which expression is equivalent to thi sum?

Answers

Answer 1

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 2

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.

Jason buys a pair of pants for $28.97, a top for $12.82 and a scarf for $9.18. He has a gift card worth $75. If the sales tax on the purchase is $3.19, what is the total of his purchase?

Part B:
Will he have enough money left to buy a hat for $27.15?
Explain your answer.

Answers

Answer:

Explanation:

Part A:

Total purchase = 28.97 + 12.82 + 9.18 + 3.19 = 54.16$

Part B:

75$ - (54.16 + 27.15) = 75 - 81.31 = -6.31

Therefore, he won’t have enough money to buy the hat.
Part a: When you add them all together you will get $54.16

Part b: no he won’t.

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

A number has many factors including 3 and 8. What other number must also be a factor of the same number?

Answers

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.

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

Answers

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

for the first one x=2.5
for the second one x=3

Select all ratios equivalent to 2:3.

Answers

Answer:

12:18 and 10:12 (i think)

Step-by-step explanation:

After converting the given ratios in their simplest form, the equivalent form of 2:3 we get 12:18.

To find the simplest form of a fraction, you have to simplify the numerator and denominator to their lowest terms and keep dividing until you can no longer simplify the fraction any further.

The given ratios are,

12:18,

3:21,

10:12

For the ratio 12:18,

Simplify it by finding the greatest common divisor (GCD) of 12 and 18.

The GCD of 12 and 18 is 6.

By dividing both numbers by 6, we get the smallest ratio of 2:3.

Moving to the ratio of 3:21,

Find the GCD of 3 and 21, which is 3.

Dividing both numbers by 3 results in the smallest ratio of 1:7.

Find the smallest ratio for 10:12.

The GCD of 10 and 12 is 2.

Dividing both numbers by 2 gives us the smallest ratio of 5:6.

Hence, the simplest form of ratios for the given ratios are:

12:18 = 2:3,

3:21 = 1:7,

10:12 = 5:6.

Hence,

The ratio equivalent to 2:3 is 12:18.
