What is difference between 164 and 220

Answers

56 is the difference

The difference between 164 and 220 is 56.

The difference between 164 and 220 is 56. In mathematical terms, you calculate the difference by subtracting the smaller number from the larger one:

220 - 164 = 56.

The sum of two numbers is 43 . The smaller number is 19 less than the larger number. What are the numbers?

Answers

Let the smaller number be x and the larger number be y.
We can calculate this by using simultaneous equation, aka listing 2 equations out.
From given,
X + y = 43
Let this be equation no. 1
X + 19 = y
Let this number be equation 2.
We can do simultaneous equations either by substitute method or elimination. In this case I'm using substitute.
We can already obtain the value of y (in terms of x) in euqation no. 2, so all we gonna do is to put y into equation 1.
X + x + 19 = 43
Solve this by algebra.
2x = 43 - 19
X = 12
Now we know the exact value of x
Now substitute x = 12 into equation no. 2
12 + 19 = y
Y = 31
So the answer is 12 and 31
Final answer:

By setting up a system of equations, we find that the larger and smaller numbers in question are 31 and 12, respectively. We solve for the larger number first and then use it to find the smaller number.

Explanation:

To solve this problem, we can use variables to represent the two unknown numbers. Let's call the larger number x and the smaller number y. We have two pieces of information that can be turned into mathematical equations:

 

Now we can substitute the second equation into the first one to solve for x:

x + (x - 19) = 43

Simplifying the equation, we get:

2x - 19 = 43

Adding 19 to both sides gives us:

2x = 62

Dividing both sides by 2 gives us:

x = 31

Now that we have the value of x, we can find y:

y = 31 - 19

This gives us:

y = 12

Therefore, the larger number is 31 and the smaller number is 12.

Which expression represents the distance between −14.6 and −5.2 on the number line?

Answers

Hello! To answer this question, all you have to do is subtract both numbers from each other. 14.6 - 5.2 is 9.4. The numbers are 9.4 units away from each other on a number line. An expression that would represent a distance between them are 14.6 - 5.2 = x. Just make the negative numbers positive to make it easier to solve.

Answer:

9.4

Step-by-step explanation:

We are given that two integers -14.6 and -5.2

We have to find  distance between -14.6 and -5.2.

Difference between =-5.2-(14.6)

Difference=-5.2+14.6=9.4

Distance is the absolute value of 9.4

Therefore,

[tex]\mid 9.4\mid =9.4[/tex]

Distance between -14.6 and -5.2 is 9.4

Which of the binomials below is a factor of this trinomial? x^2-7x-44

Answers

x-11
because 
(x-11)(x+4)
when you multiply that you get x^2 - 7x -44

Answer:

C. (x -11)

Step-by-step explanation:

The given trinomial is [tex]x^2 - 7x - 44[/tex]

Let's factor it. To find factor, we need to find the factors of -44 such that when you add them, we have to get -7

-44 = -11*4

- 7 = -11 + 4

so the correct factors are -11 and 4

Now we can write the middle term - 7x = -11x + 4x

[tex]x^2 - 7x - 44 = x^2 - 11x + 4x - 44[/tex]

Now let's group the first two terms and second two terms and factor it.

= x(x - 11) + 4(x - 11)

Here (x-11) is common factor, so we can take outside and rewrite.

= (x - 11)(x + 4)

So the factors are (x - 11) and (x + 4)

Answer is C. (x -11)

Joe tapped his maple tree to get syrup. The tree filled 3/4 of a cup in 1/2 hour.At what rate does syrup flow from the tree?

Answers

Okay. 3/4 of a cup of maple syrup is filled in 1/2 an hour. We can divide fractions to find the rate that the tree runs out syrup. To divide fractions, keep the first fraction the same, change multiplication into division, and flip the second fraction over. It would look like this: 3/4 * 2/1. 3/4 * 2/1 is 6/4 or 1 1/2 in mixed number form. Syrup flows from the tree at 1 1/2 cups per hour.

The rate of flow of syrup from the tree will be in mixed fraction form, equal to 1 1/2.

What are arithmetic Operations?

The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or even more items.

Included in them is the study of integers, especially the order of operations, which is important for all other areas of mathematics, notably algebra, data management, and geometry.

As per the data mentioned in the question,

The amount of syrup obtained from the tree = 3/4 cup

The time is taken to fill 3/4 cup = 1/2 hour

Then, the rate of flow of syrup will be,

(3/4) ÷ (1/2)

3/4 × 2/1

= 6/4 = 3/2

It can also be written in mixed fraction form,

= 1 1/2

Naomi has 50 red beads and white beads. The number of red beads is 1 more than 6 times the number of white beads. How many red beads does Noami have?

Answers

Let the number of red beads be r.
Let the number of white beads be w.

r + w = 50
r = 6w + 1

Substitute 6w + 1 in for r in the first equation.

6w + 1 + w = 50

7w + 1 = 50

7w = 49

w = 7

She has 7 white beads.

Now we use the first equation to find the number of red beads.

r + w = 50

r + 7 = 50

r = 43

She has 43 red beads.

You measure the width of a doorway and find that it is 0.93 m wide. Find the greatest possible error of your measurement

Answers

Answer:

0.5 m

Step-by-step explanation:

The greatest possible error is 1/2 of the unit you are measuring in.

We are measuring in meters; this means the greatest possible error is 0.5 m.

Answer:

The right answer is 0.005m

Step-by-step explanation:

The greatest possible error in a measurement is the half of the measuring unit, it is one hald of the precision unit.  

To solve it first you should recognize the measurement unit, in this case meters.  

Then, because it is 0.93, you should notice that the last decimal occupies the place of the hundredth, so the GPE might be: 0.01/2 equal to 0.005, your answer.  

convert 220 from degrees to radians

I hope this helps.

The conversion of the given degrees 220° is equal to 11π/9 radians approximately.

To convert degrees to radians, use the following formula:

radians = degrees × (π / 180)

Let's apply this formula to convert 220 degrees to radians:

radians = 220 × (π / 180)

radians = 220π / 180

Now, to simplify the fraction, you can divide both the numerator and denominator by their greatest common divisor, which is 20:

radians = (220/20)π / (180/20)

radians = 11π / 9

Therefore, 220 degrees is equal to approximately 11π/9 radians.

Answers

1 foot is 12 inches. 18 feet is 18×12=216 inches. each segment is 8 inch measurement, so 18 feet has 216÷8=27 segments. so the correct answer is 27 segments

By dividing the total length by the length of the pieces, we conclude that we can make 2 of these pieces.

How many 8 inch segments will be cut?

To get this, we need to divide the total length by the length of the desired pieces, and then round to the next (lowest) whole number.

Then we get:

N = 18ft/8ft = 2.25

Rounding to the next whole number we get 2, so we conclude that with 18t of ribbon we can make 2 pieces of 8ft each.

To make lemonade, you used one gallon of water, four quarts of lemon juice, and 32 ounces of honey. How many quarts of lemonade did you make?

Answers

Well, there's 4 quarts in a gallon, so 1 gallon of water would equal 4 quarts of water.

We already know there are 4 quarts of lemon juice.

And there are 32 ounces in a quart, so that would equal 1 quart of honey.

So all you need to do now is add 4 quarts, 4 quarts, and 1 quart to get 9 quarts. You would get 9 quarts of lemonade.

I hope this helped you! :)
Final answer:

To make lemonade, using one gallon of water, four quarts of lemon juice, and 32 ounces of honey, you would make 34 quarts of lemonade.

Explanation:

First, notice that gallons are larger than quarts. You are moving from a larger unit of measure to a smaller unit of measure. This means you will need to multiply. There are 4 quarts in a gallon, so your conversion factor is 4. Now, multiply. Take the given number of gallons and multiply by 4.

8(1/2) x 4 = (17/2) x (4/1) = 68/2 = 34

The answer is 8(1/2) gallons - 34 quarts.

Final answer:

The body metabolizes and eliminates alcohol at a fixed rate, which can only be sped up with time. Hydrating and eating food may make you feel better, but they do not speed up the process of becoming sober.

Explanation:

The only way to sober up after drinking is to allow time for your body to metabolize and eliminate the alcohol. No amount of coffee, water, or food can speed up this process. The liver processes alcohol at a fixed rate, and it takes about one hour to metabolize one standard drink. Other factors such as sex, weight, and age can affect this rate, but ultimately, getting sober just takes time. While waiting to sober up, hydrating and eating food can make you feel better, but doesn't actually speed up the sobriety process.
