Multiplication is a method of finding the product of two or more numbers. After 8 months the cost of computer processor is $72

What is Multiplication?

multiplication is a method of finding the product of two or more numbers.

It is given that,

A computer processor costs initially $96.00

It is expected that in 8 months the processor will cost 3/4 its current price.

Which means its cost will 3/4 times of 96.

Whenever we use times it means product or multiply.

Three by four times of ninety six

3/4 ×96.

288/4

For questions 7 and 8 find the unknown angle.

Answers

Answer:

58 degrees for Question 7, and 71 degrees for Question 8

Step-by-step explanation:

For question 7:

180 - 99 = 81

81 + 41 = 122

180 - 122 = 58

For Question 8:

142 / 2 = 71

Answer: 7) 58 degrees 8) 71 degrees

Step-by-step explanation:

7) 41 + x = 99 degrees (the two interior opposite angle is equal to the exterior angle)

subtract 41 on both sides

x = (99 - 41) degrees

x = 58 degrees

8) x + x = 142 degrees

2x = 142

divide 2 on both sides

x = 71 degrees

Ellen Greenberg loves to make and fly kites. Ellen is planning to open a shop that
sells custom-made kites. She asks for your advice to help her set financial goals.
Ellen estimates that after expenses, she can make a $15 profit on each kite she
sells. If her annual income goal is $15,400, how many kites will she have to sell?

Answers

Answer:

She must sell 1026.66666667 kites

Step-by-step explanation:

15,400/15

The number of kites that Ellen needs to sell to complete her annual goal is 1027.

What is Division?

The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.

Given that Ellen can make a $15 profit on each kite she sells. Also, Ellen's annual income goal is to have $15,400. Therefore, the number of kites that Ellen needs to sell is,

Number of kites that Ellen will sell = Annual income goal/Profit on each kite

Number of kites that Ellen will sell = $15,400 / $15

                                                     = 1026.6667

Since Ellen can not sell half kites, therefore, she needs to sell 1027 kites to complete her annual income goal.

Hence, the number of kites that Ellen needs to sell to complete her annual goal is 1027.

Answers

-3r+5r=2r
This is the right answer

Answer:

2r

Step-by-step explanation:

2r is the answer because:

We have to switch the -3r in to +3r and positive + positive = positive.

Then we change the add sign in to subtracting sign and we subtract:

3r-5r and  it will give us:

2r

And we keep the answer positive  because our answer was a +5r so the bigger number keeps the sign  the same.

Which statement best describes the domain of the function represented in the graph?

Answers

Given:

The graph of a function.

To find:

The correct statement for the domain of the given function graph.

Solution:

Domain is the set of x-values for which the function is defined or it is the set  of input values.

From the given graph it is clear that it is a linear function with end points (1,2) and (9,14).

So, the given function is defined for [tex]1\leq x\leq 9[/tex]. Here 1 and 9 are including in the set of x-values.

Therefore, the correct option is C, i.e., [tex]1\leq x\leq 9[/tex] or x between 1 and 9, inclusive.

Part b:How did you determine your answer in part A/Question 2?

Answers

Answer:the answer for part A is SAS.

Step-by-step explanation:

We already know that side PQ is the same length for both the triangles. We were then given the information that sides PM and PN were equal. So now we already have two sides that are the same. Then we were given the information that angle MPQ and angle NPQ were also equal. So now we have two sides and an angle that are equal. This is how we got SAS (side angle side).

I’m thinking of a number. When you multiply it by 3 and subtract 10 you will get a number less than 5. Form an inequality and solve it to describe the range of possible numbers

Answers

Answer:

[tex]3x-10<5\\x<5[/tex]

Step-by-step explanation:

Let x be equal to the number.

We can use what the question gives us to directly form a mathematical statement. When you multiply it by 3 (3x) and then subtract 10 (3x-10) you will get a number less than 5 (<5). Using this, our mathematical statement would look like this:

[tex]3x-10<5[/tex]

To find the range of possible values, we must solve the inequality and isolate x.

[tex]3x-10<5[/tex]

Add 10 to both sides

[tex]3x-10+10<5+10\\3x<15[/tex]

Divide both sides by 3

[tex]\frac{3x}{3}<\frac{15}{3}\\x<5[/tex]

the sum of two numbers is 84 and one of them is 12 more than the other what are the two numbers​

Answers

The first number is x

The second number is y

So according to the given condition the sum of these two numbers is 84, so we can write

x+y=84 ————-(1)

Again one of them is more than 12 than the other that's why we can write,

x+12=y -------------(2)

Now putting the values of y in equation (1) we get,

x+x+12=84

=>2x+12=84

=>2x+12–12=84–12

=>2x=72

=>2x/2=72/2

=>x=36

Taking the value of x in equation(2) we get,

36+12=y

=>y=48

The two numbers are 48 and 36.

Check:

48+36=84

=>84=84

Also 48 =36+12; which is more than 12 of 36.
