What is dilation?

Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered. There is no effect of dilation on the angle.

Laurie will draw a scale model of the garden she wants to plant. Her scale will be 1 cm = 2.5 ft. Then the scale factor will be 2.5 feet per cm.

The dimension of the garden will be 8.5 cm by 4 cm. Then the actual dimensions of Laurie’s garden will be

Length = 8.5 x 2.5

Length = 21.25 feet

Width = 4 x 2.5

Width = 10 feet

The actual dimensions of Laurie’s garden will be 10 feet by 21.25 feet. Then the correct option is D.

8 meters increased by 25% is how many meters.

Answers

First find 25% of 8
multiply 25/100 or 0.25 by 8. you get 2. This is the same as dividing 8 by 4 (or
8 x 1/4).
Then add that 25%, which is 2, to 8 meters and you get 10 meters
easy peasy :)

hope this helps

Since 25% is 1/4 of 100%, then you do 8/4 and you get 2 and then you do 2 + 8 = 10.

Can you solve 2(2x-1)+2x=6(x-1) for me? I am not sure how. And how many solutions are there?

Answers

2(2x-1)+2x = 6(x - 1)

4x - 2 + 2x = 6x - 6

6x - 2 = 6x - 6

Subtract both sides by 6x and we have -2=-6, which is false equation, therefore there is no solution.

the table shows two options provided by high speed internet. option 1 have set up fee of $50 with $30 per month. option 2 have no set up fee and is $40 per month. in how many months will the total cost of both options be the same? what will that cost be? if you plan to cancel your internet service after 9 months, which is the cheaper option?

Answers

Let us take the case of first option first
Set up fee that need to paid = $50
Per month charge of using internet = $30
Now let us take the case of the second option
Set up fee that need to be paid = $0
Per month charge of using the internet = $40
Let us assume the number of months after which both options will be same = x
Then
50 + 30x = 40x
40x - 30x = 50
10x = 50
x = 50/10
= 5
So after 5 months both the options will be same
Now to find the cost after 5 months
we can take any option for calculating = 40x
= (40 * 5) dollars
= 200 dollars
So after 5 months that amount that need to be paid is $200 for any of the plans
In case of the first option,
Cost after 9 months = 50 + 30x
= 50 + (30 * 9)
= 50 + 270
= 320 dollars
After 9 months the cost using second option = 40x
= (40 * 9)
= 360 dollars
So after 9 months the first option will be cheaper.

How do we get .375 into a percent

Answers

You turn it into a percent by multiplying by 100 because a percent means out of a hundred so that's how you do it. You just multiply the decimal by 100.

percent is just multiplying 100 to the number,
so multiply 0.375 with 100
which gets you 37.5%
