Fill in the blank to complete the equation below. 99 + 33 = 11(?+3)

Answers

Answer:

? = 9

Step-by-step explanation:

you know 99 + 33 = 132 so you can substitute that: 132 = 11 (? + 3). im going to change ? into x for now: 132 = 11 (x + 3). then distribute the 11 so 132 = 11x + 33. then subtract 33 from both sides (99 = 11x) and divide both side by 11 (x = 9) and you get 9!

hope this helps!

John is performing an experiment in which a solution alternates between a clear color and a bluish-purple color at a regular time interval. He observes that the time interval between color changes is 30 seconds (s). Sally replicates the experiment with the same solution, but at a temperature that is 10 degrees Celsius (°C) higher. What is the most likely time interval between color changes at this higher temperature?

Answers

Answer:

15 seconds

Step-by-step explanation:

The given parameters for the experiment are;

The time it takes the solution to change from a clear color to a bluish-purple color at a given temperature = 30 seconds

The temperature at which Sally replicates the experiment with the same solution = 10°C higher than the temperature the experiment was carried out by John

Given that the process involves a change in color, which is a characteristic of a chemical reaction, and that the rate of a chemical reaction increases as the temperature of the reacting system is increased, we have time it takes for the solution to change color at a temperature increased by 10°C, will be a time lesser than 30 seconds

Answers

Answer:

For example, if a car runs 44 km on 2 litres of petrol then we can use the unitary method to find out the kilometres it will cover on 1 litre of petrol. In other words, the method by which we find out the value of one unit and further use it to find the value of multiple units is known as the unitary method.

Answer:

2/5 or .4

Step-by-step explanation:

basically look at the points where the line meets the graph. two points would be 0,20 and 50,40. then count the amount that it changes vertically and then horizontally. +20vertical +50 horizonal giving the slope 20/50. this can then be simplified to 2/5 or the equivalent number .4

Answer:

If I remember correctly, the slope would be 2/5.

Brenda won 59 lollipops playing hoops at
the county fair. At school she gave two to
every student in her math class. She only
has 1 remaining. How many students are
in her class?

Answers

30. since there is 1 remaining, you take that away from 59, leaving you with 58. you would then divide 58 by 2 since each classmate gets 2. that results in the final answer of 29. however, she’s in that class too so you would add one for her making it 30

Which of the following
represents a function?
PLEASE HELP 15 POINTS OR BRAINLIEST JUST ASK PLEASE HELP ME

Answers

Answer:

A: represents a function

Explanation:

Every other option, A, has two y for one x.

It can be a function if there is 1x for 1y.

If this was helpful, please mark brainliest. Have a beautiful day!

Answer: Choice C (upper right corner)

Choice A is not a function because x = 2 leads to more than one y value (y = 1 and y = 7 at the same time)

Choice B is not a function for similar reasoning. Here we have x = 1 lead to y = 2 and y = 5 simultaneously.

Choice D is also not a function because of the two points (5,2) and (5,4). This tells us we have x = 5 lead to y = 2 and y = 4 at the same time.

A function is only possible if you have any input lead to exactly one output. Choice C shows this. Note how it passes the vertical line test. It is impossible to draw a vertical line through more than two points on the function curve.

Answers

Answer:

1st box: 2

2nd box: 5

3rd box: 8

4th box: 11

5th box: 14

Step-by-step explanation: Plug in the formula y=3x+5. For example, you plug -1 as x, and you get y=(3)(-1)+5. 3 x -1 is -3, and then you add 5. The final answer is 2. Just do the same thing on the other boxes. Use the x values and plug it in into the formula shown.

All you have to do to find y is plug in the values of x given in the chart and onto the equation

1st: x = -1
y = 3x + 5
y = 3(-1) + 5
y = -3 + 5
y = 2

(-1, 2)

2nd: x = 0
y = 3x + 5
y = 3(0) + 5
y = 0 + 5
y = 5

(0,5)

3rd: x = 1 y= 8

4th: x = 2 y= 11

5th: x = 3 y= 14

Holly and Ethan decide to sell some of their books at a flea market. The booth rental costs $15, and they will sell each book for $1.50. How many books will Holly and Ethan need to sell to make a profit of exactly $30?

Answers

Answer:The answer would be 20 books divide 15 \ 1.50 equals 10 then multiply 10 by 2

Step-by-step explanation:

The number of books sold by Holly and Ethan to get a profit of $30 will be 20.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Holly and Ethan decide to sell some of their books at a flea market. The booth rental costs $15, and they will sell each book for $1.50.

The number of books will be calculated as,

1.5x = 30

x = 30 / 1.5

x = 20

Therefore, the number of books sold by Holly and Ethan to get a profit of $30 will be 20.

1101101+11011 in binary numbers please help

Answers

Answer:

The answer is 1000 1000

Step-by-step explanation:

In HEX, it would be 88.

In DEC, it would be 136.

In Oct, it would be 210.

Binary, how to add numbers together.

1101101

+ 11011

10001000

This is just like adding regular numbers together.

For example, when you add 88 to 55, this is what will happen

1(r)

+ 55

13(+1) 3

143

With binary, when 1 and 0 are added together, the result is 1. When 1 and 1 are added together, the result is 1 and 0 (1 being the "remainder", or the number that is carried over. This number is then added to the next part of the number when adding, just like in normal addition.
