9) How many 2/5 s can you get from 4/5?​

Answers

So, 2

“How many 2/5 are in 1?”

I love the easy ones!

The real math folks generally ignore them I guess because the easy ones are not worth their time, leaving said easy ones to dilettantes like me, who then look smarter-than-I-really-am to the noobies.

Love the easy ones.

So, to the question: How many two-fifths are in one?

Well now. How shall we handle this? Hmm…

I know! Let's count the fifths (just numbers, no booze), because it's probably as good a way of getting to an answer as any other way, the question is about fifths, and counting the fifths will at least give us a picture of what we're dealing with here.

Let's jump ahead, to see where we want to end up:

We want to end up with five fifths, also known as 5/5, because 5/5 is the same as 1. How do I know that 5/5 is the same as 1? Well, I know (you'll just have to trust me on this) because saying “5/5” is the same as saying “5 divided by 5”, and saying “1/2” is the same as saying “1 divided by 2", and so on. This is true for all fractions.

So: if 5/5 is the same as 5 divided by 5, then 5/5 equals 1. (You can see why, right? Any number divided into itself is equal to one; also, five goes into five exactly one time!).

And counting the fifths,

1/5 + 1/5 + 1/5 + 1/5 + 1/5 = 5/5 = 1

Or, to count them another way,

1/5 + 1/5 = 2/5

2/5 + 1/5 = 3/5

3/5 + 1/5 = 4/5

4/5 + 1/5 = 5/5

Now that we can see what's inside of that 5/5, let's count how many two-fifths are in five-fifths by adding 2/5 together until we get as close to 5/5 as possible without going over:

2/5 + 2/5 = 4/5

leaving just 1/5 remainder, meaning that there are two 2/5 in 5/5.

We can see that that is true and correct by looking at our little counting exercise above.

Now to make sure our reasoning is clear let's count our fifths again, this time slightly rearranging the way we write the numbers, and then taking things one step further:

(1/5 + 1/5) + (1/5 + 1/5) + 1/5 = 5/5

(2/5) + (2/5) + (1/5) = 5/5

And there it is: there are two 2/5 in 1!

So let's complete the addition for the sake of those like myself who need to see these things through to their furthest conclusion:

(2/5) + (2/5) + (1/5) = 5/5

4/5 + 1/5 = 5/5

5/5 = 5/5

5/5 = 1

1 = 1. And 2/5+2/5=4/5.

17) Find DE 3x - 28 3x – 30 G E F 33​

Answers

The numerical length of DE is 11.

We have a Line Segment DG such that E and F is between D and G.

We have to determine the length of DE.

What is Line Segment?

A line segment is a piece or part of a line having two endpoints. Unlike a line, a line segment has a definite length.

According to question, we have -

DE = 3x - 28

EF = 3x - 30

FG = x

DG = 33

Now -

DG = DE + EF + FG

33 = 3x - 28 + 3x - 30 + x

7x = 33 + 58

7x = 91

x = 13

Therefore -

DE = 3x - 28 = 3 x 13 - 28 = 39 - 28 = 11

Therefore -  DE = 11

Hence, the numerical length of DE is 11.

on a graph there are two points (0,3) and (8,0) what is the proper equation​

Answers

Answer:

The line equation of the line is:

[tex]y=-\frac{3}{8}x+3[/tex]          

Step-by-step explanation:

Given the two points

(0,3)(8,0)

Finding the slope between (0,3) and (8,0)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(0,\:3\right),\:\left(x_2,\:y_2\right)=\left(8,\:0\right)[/tex]

[tex]m=\frac{0-3}{8-0}[/tex]

[tex]m=-\frac{3}{8}[/tex]

Therefore, the slope of the line: m = -3/8

Using the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where m is the slope of the line and (x₁, y₁) is the point

substituting the values m = -3/8 and the point (0,3)

[tex]y-3=-\frac{3}{8}\left(x-0\right)[/tex]

[tex]y-3=-\frac{3}{8}x[/tex]

Add 3 to both sides

[tex]y-3+3=-\frac{3}{8}x+3[/tex]

Simplify

[tex]y=-\frac{3}{8}x+3[/tex]

Therefore, the line equation of the line is:

[tex]y=-\frac{3}{8}x+3[/tex]

Step-by-step explanation:

If you substitute the values x = 0 and y = −5 into the second equation, you get a false statement: 2(−5) − 10 = 2(0). To solve this system, try rewriting the first equation as x = 2y − 8. Then substitute 2y − 8 in for x in the second equation, and solve for y. The correct answer is x = −2, y = 3.

Answer:

-1 -9i, where a = -1 and b = -9

Step-by-step explanation:

1st step is to open up the brackets. Since there's a (-) in front of the second bracket, we have to multiply every term by -1, so positive becomes negative, negative becomes positive etc.

4-i-5-8i

Then we collect like terms.

-1 -9i

This is the answer. It looks wrong since the variables are 'positive' in a +bi, but you have to remember that a variable can be represented as a, but its actual value could be negative, in this case -1. This is the same with b, as b could be the same as -9.

This is an expression, so we can't multiply everything by -1 to make it 'look right'. You can only multiply by -1 or 'alter' the terms when the expression equates to something.

Answer:

I think it is the third choice

The absolute value equation can be used to calculate Jack's maximum and minimum time to fold his laundry is, |x−30|=10. So, Option A is correct

What is an Equation ?

An equation is a mathematical term, which indicates that the value of two algebraic expressions are equal. There are various parts of an equation which are, coefficients, variables, constants, terms, operators, expressions, and equal to sign.

For example, 3x+2y=0.

Types of equation

1. Linear Equation

2. Quadratic Equation

3. Cubic Equation

Given that,

On average, Jack can fold his laundry in 30 minutes

How much laundry he has, his time can vary from the average by 10 minutes

So, maximum time can be 40 minutes

And minimum time can be 20 minutes

Therefore, The result is  |x-30| =10
