Noah says that to find 20% of a number he divides the number by 5. For example, 20% of 60 is 12, because . Does Noah's method always work? Explain why or why not.

Answers

Answer 1

Answer:

Yes Noah's method will always work

Step-by-step explanation:

Noah's method states that:

To find 20% of a number he divides the number by 5. For example, 20% of 60 is 12.

Noah's method will always work because:

20% = 20/100

Simplifying 20/100 to the least fraction = 20/100 = 1/5

20% of x = 1/5 × x

= x/5 = x ÷ 5

Applying this to the examples

20% of 60 = 1/5 × 60

= 60/5 = 12.

Therefore, Noah's method will always work.

Step-by-step explanation

I got my driver's license last week

Just like we always talked about

'Cause you were so excited for me

To finally drive up to your house

But today I drove through the suburbs

Crying 'cause you weren't around

And you're probably with that blonde girl

Who always made me doubt

She's so much older than me

She's everything I'm insecure about

Yeah, today I drove through the suburbs

'Cause how could I ever love someone else?

And I know we weren't perfect but I've never felt this way for no one

And I just can't imagine how you could be so okay now that I'm gone

Guess you didn't mean what you wrote in that song about me

'Cause you said forever now I drive alone past your street

And all my friends are tired

Of hearing how much I miss you but

I kinda feel sorry for them

'Cause they'll never know you the way that I do

Yeah, today I drove through the suburbs

And pictured I was driving home to you

And I know we weren't perfect but I've never felt this way for no one

Oh, and I just can't imagine how you could be so okay now that I'm gone

Why is the radius 4?

Answers

Answer:

Please check explanations

Step-by-step explanation:

The equation of a circle can be represented as;

(x-h)^2 + (y-k)^2 = r^2

r is the radius while (h,k) represents the coordinates of the center

Thus, we have that;

(x-2)^2 + (y+3)^2

That would give;

x^2 - 4x + 4 + y^2 + 6y + 9

The sum of values with no coefficient is;

4 + 9 = 13

If we take this to the other side, we can have 13 + 3 = 16

The square root of this is then 4

Mathematically, we can therefore express the equation of the circle as;

(x-2)^2 + (y-+3)^2 = 4^2

By expansion, we will get the original given equation

Answer:

348 of them are not postgraduates

Step-by-step explanation:

Answer:

348

Step-by-step explanation:

Out of 725 employees, 52% are postgraduates.

First find the percentage who are not postgraduates, or the "remaining."

100% - 52% = 48%

48% of 725 employees = how many employees?

48/100 × x/725

Cross multiply

48 × 725 = 100 × x

34800 = 100x

Divide both sides by 100

34800 ÷ 100 = 100x ÷ 100

348 = 1x

348 employees are not postgraduates


In a bag of marbles, there are 4 blue marbles, 6 yellow marbles, 3 red marbles and 6 green marbles. If you choose a yellow marble on your first draw and do not put it back in the bag, what is the probability you get a blue marble on the second draw? probability you get a blue marble on the second draw?

a. 1/6
b. 6/19
c. 4/19
d. 2/9

Answers

The answer would be D. Because there was 19 in total and you took a marble out so that makes it 18 then you want the probability of the blue so 4/18 which equals 2/9

This is circle theorems I am not rly good at this

Answers

Answer:

m∠BCD = 24°

Step-by-step explanation:

By the theorem,

"Angle subtended by an arc at the center of the circle is twice in measure of the angle subtended at the circumference."

m(∠BOD) = 2(m∠BFD)

                = 2(78°)

                 = 156°

Therefore, m(arc BD) = m∠BOD = 156°

Since, m(arc BD) + m(arc BFD) = 360°

156° + m(arc BFD) = 360°

m(arc BFD) = 360 - 156

                   = 204°

Since, "angle formed outside the circle by the intersection of two tangents measure half of the difference of the intercepted arcs".

m∠BCD = [tex]\frac{1}{2}[m(\text{arc BFD})-m(\text{arc BD})][/tex]

              = [tex]\frac{1}{2}[204 - 156][/tex]

              = 24°

Answers

Answer: y - 3= -1/2 * (x - 8)

Answer:

y=-1/2x+3

Step-by-step explanation:

Slope intercept form is written: y=mx+b...

y=doesn't change, but you need it by itself

m=slope

x=the variable right next to the slope

b=y-intercept

Also, don't worry! This is super simple ^^

The question gives us -1/2 as the slope, so it needs to be plugged into the equation as m (next to x). Now our equation looks like this:

y=-1/2x+b

Next, we can figure out b. B is the y-intercept and we can figure this out by looking at the ordered pair (8, 3). The y is the second number, which is 3, so that is the y-intercept! We can now plug in 3 into b. Our final equation looks like this:

y=-1/2x+3

Hope this helps!! Have an awesome day ❤

The area of the given cloth is 1/6 yards².

What is an area?The measurement that expresses the size of a region on a plane or curved surface is called an area. Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.

So, the area of the cloth:

The length of the cloth is 5/9 yards.The breadth of the cloth is 3/10 yards.

So, we know that it is a rectangular cloth.

Rachel has ridden 68 miles of a bike course. The course is 80 miles long. What percentage of the course has Rachel ridden so far?

Answers

Answer:

92%

Step-by-step explanation:

since i helped can i have brainlst please that would be greatly apericated

Answer:

85%

Percentage solution with steps:

Step 1: We make the assumption that 80 is 100% since it is our output value.

Step 2: We next represent the value we seek with x.

Step 3: From step 1, it follows that 100% = 80.

Step 4: In the same vein, x% = 68.

Step 5: This gives us a pair of simple equations:

100% = 80(1)

x% = 68(2)

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left-hand side) of both equations have the same unit (%); we have

100%/x% = 80/68

Step 7: Taking the inverse (or reciprocal) of both sides yields

x%/100% = 68/80

__>x = 85%

Therefore, 68 is 85% of 80.

She was the first woman and the first African American to deliver a keynote speech at a Democratic National Convention. Let there be no illusions about the difficulty of forming this kind of a national community. It's tough, difficult, not easy. But a spirit of harmony will survive in America only if each of us remembers that we share a common destiny; if each of us remembers, when self-interest and bitterness seem to prevail, that we share a common destiny. I have confidence that we can form this kind of national community. I have confidence that the Democratic Party can lead the way. I have that confidence. We cannot improve on the system of government handed down to us by the founders of the Republic. There is no way to improve upon that. But what we can do is to find new ways to implement that system and realize our destiny. Now I began this speech by commenting to you on the uniqueness of a Barbara Jordan making a keynote address.
