Mathematics

Answer:

To find a scale factor between two similar figures, find two corresponding sides and write the ratio of the two sides. If you begin with the smaller figure, your scale factor will be less than one. If you begin with the larger figure, your scale factor will be greater than one.

Let's say you have a very small image you want to make larger. Also, let's say you want to keep the same proportions and shape. To enlarge an image, the scale factor would be greater than 1. For example, a scale factor of 2 means you make each side or dimension twice as big.

eg: a rectangle that starts off being 2 by 3 becomes 4 by 6, after you double each side

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

Going in reverse, if the scale factor is between 0 and 1, say 1/2 = 0.5, then the image will get smaller.

Example: a 10 by 50 rectangle becomes 5 by 25 rectangle after you multiply each dimension by 0.5 (aka divide each dimension by 2).

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

So the general rule is if the scale factor is larger than 1, then the new image is larger. If the scale factor is less than 1 but greater than 0, then the image will get smaller.

Mary has $2,300. She has decided that she will withdraw a fixed whole-dollar amount of money every month of the year. The fixed
Brrunno [24]

Given : Mary has $2300

Given : Mary decides to withdraw a fixed amount of money every month of the Year.

I'm Solving this Question by Verification of the Given Options

Let us Assume, She Withdraws a fixed amount of $190 every Month

⇒ The Amount she has withdrawn in a year = (190 × 12) = $2280

⇒ The Amount left over will be : (2300 - 2280) = $20

But, we can see that there is no $20 among the 2nd Blank Options. So, This Fixed amount of money cannot be the Answer.

Let us Assume, She Withdraws a fixed amount of $181 every Month

⇒ The Amount she has withdrawn in a year = (181 × 12) = $2172

⇒ The Amount left over will be : (2300 - 2172) = $128

But, we can see that there is no $128 among the 2nd Blank Options. So, This Fixed amount of money cannot be the Answer.

Let us Assume, She Withdraws a fixed amount of $180 every Month

⇒ The Amount she has withdrawn in a year = (180 × 12) = $2160

⇒ The Amount left over will be : (2300 - 2160) = $140

But, we can see that there is no $140 among the 2nd Blank Options. So, This Fixed amount of money cannot be the Answer.

Let us Assume, She Withdraws a fixed amount of $191 every Month

⇒ The Amount she has withdrawn in a year = (191 × 12) = $2292

⇒ The Amount left over will be : (2300 - 2292) = $8

We can see that there is a $8 among the 2nd Blank Options. So, This Fixed amount of money is the Answer.

The Fixed whole-dollar amount of money she takes from her account every month is $191 and she'll have 8 left over.

First Blank : $191

Second Blank : $8

Nesterboy [21]
Answer: 26/52 or 0.5 or 50%

Step-By-Step:
So since there are 52 cards in a deck and half of them are red which does include the red ace that means you have 26/52 probability. The red aces are already including in this half of the deck and sense it is an or statement we do not need to add it back into the probability.

Help? use the rule to find the the first 10 terms in the pattern first term:7 rule:multiply by 2
alex41 [277]
So,

Start with 7.

Multiply by 2.
7 * 2 = 14

Multiply by 2.
14 * 2 = 28

Multiply by 2.
28 * 2 = 56

Multiply by 2.
56 * 2 = 112

Multiply by 2.
112 * 2 = 224

Multiply by 2.
224 * 2 = 448

Multiply by 2.
448 * 2 = 896

Multiply by 2.
896 * 2 = 1792

Multiply by 2.
1792 * 2 = 3584

The first ten terms in the pattern are:
7, 14, 28, 56, 112, 224, 448, 896, 1792, 3584

In a function:
f(x) = 2x

In a rule:
S = {x| x/7 = Whole Number}
