Answer:
The length of one side of the hot tub is 4.8ft
Step-by-step explanation:
Given
Shape: Square
-- scale factor
Required
Side length of ABCD (the hot tub)
From the question, we understand that
ABCD dilated by 5 to A'B'C'D
This implies that:
i.e. the sides of ABCD is multiplied by 5 to get A'B'C'D
So, we have:
Divide by 5
0.09 is one tick mark Behind the 1/10 or 1 over 10 mark.
0.9 is the exact mark labled 9 over 10 or 9/10.
0.19 is exactly the mark behind the 2/10 mark or 2 over 10.
0.190 is on exactly the same mark as the one above-- on the mark behind the 2/10 mark.
0.019 is does not have a place on the strip. It is in the thousandths place not the hundredths or tenths places. That is why it doesn't have a place on the strip
Hope this helps you! :)
In this case, you have to find a common multiple of 3a^2 and 4ab. As only one of the numbers is divisible by two, this means that two cannot go outside of the bracket. The only other aspect that is in both sides of the equation is a, therefore, this goes outside the bracket. The best way to approach this is to divide both sides by a, and this will give you what is inside the bracket. 3a^2 divided by a is 3a, therefore, this is the first aspect in the bracket. -4ab divided by a, leaves -4b. Therefore, these go in the bracket.
3a^2- 4ab simplified is a(3a-4b)
Hope this helps
Answer:
Step-by-step explanation:
<em>Note: 3x + 8 is incorrect as leads to negative value for the length. Therefore changed to 3x - 8</em>
<em>------------------------------------------------</em>
- DE is midsegment
- Midsegment = 1/2 Base as per definition, DE = 1/2AC
<u>Substitute values</u>
- 3x - 8 = 1/2(4x + 10)
- 3x - 8 = 2x + 5
- 3x - 2x = 5 + 8
- x = 13
DE = 3*13 - 8 = 31
