Your television remote control has buttons for digits 0-9. If your press two buttons, how many numbers are possible if

a) the same button may be pressed twice
b) the same button may not be pressed twice​

Answers

Answer 1

(A)  I got 10(10)=100 points in remote space.

(B) I also got 10(9)=90 points in remote space

Answer 2

Answer:

a) 100

b) 90

Step-by-step explanation:

For the first question, the first button you press will have 10 possibilities, from 0-9.  For the second button, you will still have 10 possibilities since the same button may be pressed twice. Therefore, you get 10*10=100.

For the second one, the same button may not be pressed twice. For the first button press, you have 10 possibilities, but for the second button, you have 1 less possibility since you aren't allowed to push the button you pressed before. So there will be 9 possibilities. 10*9=90.

A chemical compound requires 8 ounces of chemical A and 12 ounces of chemical B. A mixture contains 24 ounces of chemical A and 30 ounces of chemical B. How can you fix the mixture to make the chemical compound?

Answers

Add 6oz of chemical B and remove 1/3 of the total mixture.
I might always be wrong.
Explanation:
Since 8x3=24 and since 12x3=36 you need to add 6oz of chemical B to have 24oz of chemical A and 36oz of chemical B.
Take 1/3 of the total mixture to have 8oz of chemical A and 12oz of chemical B.

A division problem has 43 as its divisor. The partial quotient are 20 and 7. The remainder is 19. What is the dividend?

Answers

x / 43 = 27 and 19/x

Multiply by 43 and 27 and add 19
43*27 + 19
1161 + 19
1180

Check:
1180/43 = 27.4418605
27.4418605 = 27 and 19/43

A division problem has 43 as its divisor. Then the value of the dividend will be 1,180.

What is Algebra?

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

The formula is given as,

Dividend = Quotient × Divisor + Remainder

A division issue has 43 as its divisor. The halfway remainder are 20 and 7. The rest of 19.

Dividend = (20 + 7) × 43 + 19

Dividend = 27 × 43 + 19

Dividend = 1,161 + 19

Dividend = 1,180

A division problem has 43 as its divisor. Then the value of the dividend will be 1,180.

convert 9 1/9 into a improper fraction

Answers

Answer:

82/9

Step-by-step explanation:

The improper fraction is 82/9.

What is improper fraction?

An improper fraction is a type of fraction where the numerator is greater than or equal to the denominator. For example, 5/2 and 8/5, are improper fractions. Every fraction has two parts, numerator, and denominator. In mathematics, there are two main types of fractions based on the values of numerator and denominator, and those are proper fractions and improper fractions.

A fraction whose numerator is greater than or larger than the denominator is defined as an improper fraction such as 7/3 and 12/5.

Given fraction:

9 1/9

Now, converting into improper fraction

Numerator = 9 x 9 + 1

                   =81 + 1

                   = 82

and, Denominator = 9

So, the improper fraction is 82/9.

Erica had a stack of firewood on Monday. OnTuesday she used 1/2 of the

660 will be your answer

find the measure of each angle indicated and please explain how you got that answer if you can ​

Answers

#15- The answer should be 35.
In the photo I included, both points A and B are equal, because they are intersecting. To get the measurement for these angles, you add 40+40 to get 80. We know that three angles in a triangle need to add up to 180, so you would subtract 80 to get 100. If point A and B are 100, that means you can add 100+45 to get 145, and subtract that from 180 to get your answer. (35)

#16- The answer should be 42. Using the same logic as before, take away 80+40 from 180 to get 60 for points A and B. Then you would subtract 78+60 from 180 to get your answer. (42)

#17- The answer should be 108. You need to find the final angle of the triangle by subtracting 37+71 from 180. This would equal 72. Since the angle of a line is 180 degrees, you would subtract 72 from 180 to get the finished product. (108)

#18- The answer should be 35. You would start by finding the bottom left angle. You would use the same logic as I did in #17 by subtracting 180-126. This tells you that the bottom left angle in the triangle is 54. Then you would subtract 91+54 from 180 to get your answer. (35)

I hope this helps and that it wasn’t too confusing. #17 and #18 aren’t my strong suit, so I’m sorry if I’m wrong. Please mark brainliest!

Hi! I hope this helps a bit because I'm just gonna give a few things you can talk about...I'm not writing a whole essay lol...

School impacts us in an extremely large variety of ways. Personally, I think it has more negative effects than positive. For example, at a school environment, there are so many ways to get exposed to profanity by your peers. There are definitely ways to be engaged with people who impact your entire life because of swearing. Similarly, students can learn and get very involved in having horrible behavior. Last but not least, I know that bullying is a huge problem at school. Even if it's being done unintentionally, students can really harm both the physical and mental strength of others.

Answers

Answer:

Kylie is 24 years old

Step-by-step explanation:

kylie = x

Bobby=x-5

x+x-5=43

2x-5=43

2x=43+5

2x=48

X=24 years old

19

If you subtract 5 off of 43 and divide it by two you find Kylie's age. The reason you divide by two is because there are two people and it is a combined age, meaning you would divide by two.
