Answer:

The scale factor of this dilation is [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

The length of AC is 8, which is given. Since AC' is the dilated side that corresponds to AC, and the length is 4, that means the scale factor of dilation from ABC to AB'C' is [tex]\frac{4}{8}[/tex] or [tex]\frac{1}{2}[/tex].

1. A number is as much greater than 21 as it is less than 71. Find the number

Solution -

Let the number be x.

As both the value of x - 21 and 71 - x is same hence,

=> x - 21 = 71 - x

=> x + x = 71 + 21

=> 2x = 92

=> x = 92/2

=> x = 46

Hence, the number is 46.

2. Find 2 consecutive natural number whose sum is 63.

Let the two consecutive numbers be x and x + 1.

=> x + (x + 1) = 63 (A.T.Q)

=> x + x + 1 = 63

=> 2x = 63 - 1

=> 2x = 62

=> x =62/2

=> x = 31

Hence, the consecutive natural numbers whose sum is 63 are 31 and 32.

Answer:

3x+3x+7x+20+7x+20=360

20x=360-20

20x=320

x=16

therefore x=16 so,

7x+20+y=180

but x=16

7(16)+20+y=180

y=180-132

y=48

Answer:

9,354,9,157,9,012,9,1

Step-by-step explanation:

First I do thousands place so 3 numbers have 9 for thousands place.

Numbers are

9,354

9,157

9,012

it cant be 9,012 because this number don't have a hundreds place.

But in hundred place 9,354 would be better than 9,157 because 9,354 had 300 while 9,157 only has 100.

So greatest=9,354

Second greatest=9,157

And last 9,000 number third greatest=9,012.

Our last numbers don't have hundreds or thousands,they have ones but 9 is greater than 1 because...

Say you had 9 pizzas and your friend had 1 you would have more or a greater amount so.

Least=1

and second least=9

Meaning order=

9,356=greatest

9,157

9,012

9

1=least

Hope it helps have a great day:)

Step-by-step explanation:

mean : 8.8

The mean is the average, so you find it by adding all the numbers together and dividing by n, or how many numbers there are. For this, I added to get 70.4 and divided that by 8 (8 total scores).

70.4/8 = 8.8.

median : 8.85

The median is the middle of the data set, so you put the numbers in increasing order (lowest number to highest number) and then finding the middle of that set. For this set, since there is an even number of numbers (8), you have to find the middle by adding the two middle numbers and dividing by 2.

8.2, 8.7, 8.8, 8.8, 8.9, 8.9, 8.9, 9.2

The middle numbers are 8.8 and 8.9, so you add those together and divide by 2 to get 8.85.  

mode : 8.9

The mode is just what number appears most often. Because 8.9 appears three times in this data set, more than any other number, the mode is 8.9.

b. The mean reflects a typical score because it is the average, and is used most often when someone is expressing a typical or "average" score. It is the score most people are likely to get, and as there are no outliers in this data set, it reflects a typical score for this data set. It is also the same as the mode, or most often score, in this data set.

1) Put the numbers in order

      8.2, 8.7, 8.8, 8.8, 8.9, 8.9, 8.9, 9.2

2) mean is average

     70.4/8 = 8.8

3) Median is the middle number; if m = 2, then divide them by 2

     17.7/2 = 8.85

4) Mode is most often

     8.9 (3 times)

Answer:

-2k + 4

Step-by-step explanation:

Given:

Incorrect work / solution

7k + 14 - 9k - 10 = 16k + 4

Error is the simplification of the like terms, that is, 7k - 9k

Correct work / solution

7k + 14 - 9k - 10

Collect like terms

= 7k - 9k + 14 - 10

= -2k + 4

The error made was adding 7k and 9k together, instead of subtracting 9k from 7k which gives -2k as answer

Answer: x =  87.5

................

Answer:

87.5

Step-by-step explanation:

40% of x = 35 , that is

[tex]\frac{40}{100}[/tex] x = 35

0.4x = 35 ( divide both sides by 0.4 )

x = [tex]\frac{35}{0.4}[/tex] = 87.5

Answer:

b) |y-11|=6

c) |z-1|=5

d) |a-0|=1/2

Step-by-step explanation:

This definetly works!

The absolute value equations are =

1) |x - 11| = 6

2) |x + 1| = 5

3) |x| = 0.5

1) To satisfy the solution set of 5 and 17 on a number line, we can write an absolute value equation as follows:

|x - 11| = 6

Explanation: The midpoint between 5 and 17 is 11, which serves as the value c in the equation.

The absolute value of x minus 11 should be equal to the distance between the midpoint and either endpoint, which is 6.

2) To satisfy the solution set of -4 and 6 on a number line, we can write an absolute value equation as follows:

|x + 1| = 5

Explanation: The midpoint between -4 and 6 is -1, which is the value c in the equation.

The absolute value of x plus 1 should be equal to the distance between the midpoint and either endpoint, which is 5.

3) To satisfy the solution set of -0.5 and 0.5 on a number line, we can write an absolute value equation as follows:

|x| = 0.5

Explanation: In this case, the midpoint between -0.5 and 0.5 is 0, which is the value c in the equation.

The absolute value of x should be equal to the distance between the midpoint and either endpoint, which is 0.5.

Step-by-step explanation:

Here is the formula.

[tex]A=P(1+r)^{n}[/tex]

A = Final Value

P = Starting Value

R = Rate

N = Time in Years

A = 8,000,000,000

P = 5,400,000,000

R = 0.0195

N = Time in Years

Solve for n.

20.35 Years from 1990; so sometime in 2011 the population would be 8 billion.

Answers:

The forces have opposite directions

The forces have equal magnitudes

=====================================================

Explanation:

Imagine a bucket of water being held up by a rope.

Gravity pulls down on the bucket with a constant force. The reason why the bucket doesn't fall to the ground is because the tension in the rope is holding it up.

More specifically, the force of the rope's tension is exactly matching the force of gravity. So we have equal magnitudes here. However, the force vectors point in complete opposite directions. Gravity points down and the tension of the rope points up. The two opposite directions cancel out to create balance and that's why the object doesn't move. It has velocity = 0 which is considered a constant velocity even though it's not something like 3 m/s.

If the forces acted in the same direction, then the magnitudes would add up to accelerate the object (either downward or upward). However, the bucket stays fixed in place, so it's clear that the vectors must be opposite in nature.

---------------

Now consider a skydiver. At some point of the descent, the skydiver will hit terminal velocity. This is the fastest s/he can fall because the force of gravity pulling down counterbalances perfectly with the upward force of wind/air resistance pushing upward. The air is resisting the downward motion being a form of friction. In this case, the magnitude of the gravitational force is the same as the magnitude of the upward air resistance.

Unlike the bucket of water, the skydiver is of course moving. They are moving at a constant velocity since they cannot accelerate any faster. Hence the name "terminal" meaning "the final or ending velocity". It is when the parachute is deployed that will apply a much greater upward force, which then slows down the downward velocity to allow the skydiver to safely land.

---------------

In both examples, we have a constant velocity happening when the vectors pull in equal amounts but in opposite directions. Think of it like a tug-of-war to keep everything balance. If there is an imbalance of any kind, then acceleration will happen.
