Answers

Answer 1
Answer:

The value of the expression 4 x 12, using multiplication distributive propoerty, is 48.

What is multiplication?

Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression for some number of times.

Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.

Given:

An expression,

4 x 12.

To find the product:

We will apply the multiplicationoperation.

4 x 12

= 4 x (10 + 2)

Using the process of distributiveproperty,

= 4x 10 + 4 x 2

= 40 + 8

= 48.

Therefore, the value of the product is 48.

katia makes crafts using glass jars She can buy packages of 12 jars for $9 how many jars can kitia buy with $45

Answers

Hello!

If Katia can buy packages of jars for $9, we can determine how many packages she can purchase with $45 by using the formula:

45/9 = 5

We divide the total number of money that she has by the amount of money one package of jars costs. Now, the question also asks how many jars she can buy, not just how many packages.

We know that she can buy 5 packages, and that there are 12 jars in each package. To find the total number of jars she can buy, we will multiply 5 by 12.

5 x 12 = 60

Katia can buy 60 jars with $45.

I hope this helps you! Have a lovely day!

Amelia's mom baked 48 cookies. After Amelia and her friends walk through the kitchen, there are 18 cookies left. what is the percent increase in the number of apps Tan has on his phone

Answers

The percentage decrease in the number of cookies is given by the equation A = 62.5 %

What is Percentage Error?

The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.

Percentage error is the difference between the measured value and the true value , as a percentage of the true value

Percentage Error = [ ( | Measured Value - True Value | ) / True Value ]x 100

Given data ,

Let the percentage decrease be represented as A

Now , the equation will be

The initial number of cookies = 48 cookies

The final number of cookies = 18 cookies

So , the change in number of cookies = 48 - 18 = 30 cookies

So , the percentage decrease in cookies = ( change in number of cookies / initial number of cookies ) x 100

Substituting the values in the equation , we get

The percentage decrease in cookies A = ( 30/48 ) x 100

On simplifying the equation , we get

The percentage decrease in cookies A = 0.625 x 100

The percentage decrease in cookies A = 62.5 %

Therefore , the value of A is 62.5 %

Hence , the percentage decrease is 62.5 %
