ML = 6
Step-by-step explanation:
Since HIJ is a scale drawing of KML, this means the IJ and ML are corresponding sides. The corresponding sides have proportional lengths, so from HJ ≅ LK you can learn that the scale factor is 20 / 5 = 4. likewise you can confirm this with HI ≅ MK is 36 / 9 = 4.
So ML is found by dividing JI by 4 = 24/4 = 6.

Writing Prompt Algebra I
Your aunt is planning on building a rectangular pool that measures 10 feet by 12 feet. A
concrete walk around all four sides of the pool will also be included in the deal. However,
your aunt is not sure how big to make the width of the walk. Therefore, the width will be
“x” feet long. Your aunt is wondering how much land will be needed for the pool and the
walkway bordering the pool. You are to write a written description to your aunt telling her
how you would find the area of land needed for the pool and the walkway bordering all four
sides.
Answers
Answer: The width is 12 feet, since the pool measures 10 by 12.
Step-by-step explanation:
Your aunt will need 120 square feet of land. I know this because you multiply the length by the width, it equals 120. Then I have to look for the perimeter, and I do this by adding the length twice and add the width twice. This would equal 42.

A right triangle with side length 6 feet, s, and hypotenuse 13 feet.
[Not drawn to scale]
What is the length of Fahim’s shadow? Round to the nearest tenth of a foot.
7.0 feet
8.5 feet
11.5 feet
14.3 feet
Answers
Answer: 11.5 feet
Step-by-step explanation:
We should note that for a right angles triangle, the square of the hypothenuse equals to the square of the opposite side and its adjacent. This can be expressed as:
Let the length of Fahims shadow be x
hypotenuse² = opposite² + adjacent ²
13² = 6² + x²
169 = 36 + x²
x² = 169 - 36
x² = 133
x =✓133
x = 11.53
= 11.5 feet to nearest tenth

X-11 = 8
Answers
First, you have to get x alone by getting rid of the terms next to it. In this case, it’s -11.
To get rid of a term, do the opposite.
So x - 11 + 11 = 8 + 11
Remember to do it on both sides.
x = 19
Why?
You have to get x alone so you have to add 11 to both sides
X-11+11= 8+11
The 11 cancel out on the left and 8+11 equals 19 so x=19

Given that a = ( − 6 7 ) and b = ( − 1 − 3 ) . If a − b = ( x y ) , work out the values of x and y .
Answers
Answer:
x = -5 , y = 10
Step-by-step explanation:
As given ,
a = ( x₁ , y₁ ) = ( -6, 7)
b = ( x₂ , y₂ ) = (-1, -3)
For a -b = ( x₁ - x₂ , y₁ - y₂ )
= ( -6 - (-1) , 7 - (-3) )
= ( -6 + 1 , 7 + 3 )
= ( -5 , 10 )
⇒ a - b = ( -5, 10 ) = ( x, y)
∴ we get
x = -5 , y = 10

Step-by-step explanation:
∠BAE ≅∠DAC because they are vertical angles
∠ACD = 180 - 124 = 56°
to find 'x': 56 + 2x + (180 - 4x) = 180
236 - 2x = 180
-2x = -56
x = 28
m∠ACD = 180 - 4(28) = 180 - 112 = 68°
Will a fraction increase or decrease and by what percent if its numerator is increased by 20% and its denominator is increased by 50%?
The fraction will increase or decrease by what percent
Answers
Answer:
increase by the percent
The fraction will decrease by 20%.
What is Fraction?A fraction represents a part of a whole.
Let's assume the original fraction to be x/y.
If we increase the numerator by 20%, it becomes 1.2x.
If we increase the denominator by 50%, it becomes 1.5y.
So, the new fraction will be:
(1.2x) / (1.5y)
Simplifying this expression, we get:
(4x/5y)
The new fraction is (4/5) times the original fraction.
Therefore, the fraction will decrease by 20%.
