Answer:

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.

Fahim is 6 feet tall. At noon, he stands with the sun behind him casting a shadow. The distance from the top of Fahim’s head to the furthest tip of the shadow is 13 feet.

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

1 The length of a rectangle is 10 inches, and the
width is represented by 3x. Which best
represents an equation and solution for x if the
area of the rectangle is 40 square inches?
A 10(3x) = 40; X = 4
B 30x = 40; x = 1;
C 3x = 40; x = 13
D 3x + 10 = 40; X = 10

Answers

Answer:

A

Step-by-step explanation:

To find the area of a rectangle, it is length times width (10*3x), and if it equals 40, you could just write that after the equation, and then find out that "x" would equal [tex]\frac{4}{3}[/tex]

Answer:

30x = 40 ; x ≈ 1  

Step-by-step explanation:

[tex]A^{}[/tex] = [tex]l^{}[/tex] [tex]w^{}[/tex]

[tex]l^{}[/tex] = 10 inch.

[tex]w^{}[/tex] = 3x

10(3x) = 40

30x = 40 ; x = [tex]1\frac{1}{3}[/tex] ≈ 1

Pretty sure you have to use the Pythagorean Theorem.
a^2+b^2=c^2

So you would plug in your numbers that you already have (6 and 10) But notice that 10 is the hypotenuse (longest side) so
6^2+x=10^2

Then you would solve it and you should end up with 11.6619

Answers

Answer: 14:35 hrs

Step-by-step explanation:

Missing time that Ron left was 07:00 hrs  

Ron left the house at 07:00 hrs. If he arrived back to the house 7 hours and 35 minutes later, you can find out what time he arrived by simply adding the time he left to the time he stayed outside:

= 7 + 7hrs 35 minutes

To find:

The equivalent expression.

Solution:

We have,

[tex]=-2x^2-2xy+6x-3x+12y+3xy+5y^2-3y[/tex]

On combining like terms, we get

[tex]=-2x^2+5y^2+(-2xy+3xy)+(6x-3x)+(12y-3y)[/tex]

[tex]=-2x^2+5y^2+xy+3x+9y[/tex]

The expression [tex]-2x^2+5y^2+xy+3x+9y[/tex] is equivalent to the given expression.

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.
