Ruth decides to use the method of proportions and similar triangles to find the height of a tree. She measures the length of the

tree's shadow and finds it is 12 feet long. Then she holds a 12-inch ruler perpendicular to the ground and finds that it casts a 6-inch shadow. How tall is the tree? a. 2 ft c. 24 ft b. 6 ft d. 144 ft

Answer:

c. 24 ft

Step-by-step explanation:

if the 12 inch ruler casts a 6 inch shadow (shadow has half size) then a tree with 12 feet long shadow will have a height of 24 feet

Can someone help me pls!

This question is about how transformations can affect graphs.

First, we'll want to get rid of that -4 on the function of F.

So we can reflect the function over the y-axis and then compress it by a factor of 4 to make the graph x^2.

Then we can move the graph over to the left 3 because the c value is positive, meaning that we move the graph over to the left.

Finally, we can move the function of by \frac{2}{3} because the d value is positive, meaning that we move the graph up.

Hope this helps.

頑張って!

Find the value of x showing your steps. identify the postulate that allowed you to solve for x.​
Lena [83]

Answer:

x = 14

General Formulas and Concepts:

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

  1. Brackets
  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition
  7. Subtraction
  • Left to Right

<u>Algebra I</u>

  • Equality Properties

<u>Geometry</u>

  • Congruency
  • All angles in a triangle add up to 180°

Step-by-step explanation:

<u>Step 1: Define</u>

3(x + 7)° = 63°

3(x + 7)° + 63° + y° = 180°

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Divide 3 on both sides:                    x + 7 = 21
  2. Subtract 7 on both sides:                 x = 14

PLEASE HELP
11111nata11111 [884]

Answer:

1).  The constant of variation is 7

2).  w = 6 for the given values of x and y

Step-by-step explanation:

"Varies jointly" tells us that y is a direct result of a mathematic operation involving x and w.  We will assume y is directly prorportional to x and w, in the sense that we can find a multiplicative relationship of the form y=Kxw, where K is the constant of variation.

We are given one data point:  y=-42 where x is 2 and w is -3.  Let's put those values into our trrial expression:

y=Kxw

-42=K(2)(-3)

-42 = -6K

K = 7

<h2>The expression becames  <u>y = 7xw</u></h2>

The constant of variation is 7.

The value of w for y=3 and x=(1/14) would be:

 

  y=7xw

  3 = 7*(1/14)*w

3 = (1/2)*w

<h2><u>w = 6</u></h2>

Answer:

{5}^{8}  {x}^{6}

Step-by-step explanation:

\bigg( \frac{125   {x}^{ - 3} }{ {5}^{ - 3} \times 25 \times  {x}^{ - 6}  }  \bigg)^{2}  \\  \\  =  \bigg( \frac{ {5}^{3}    {x}^{ - 3} }{ {5}^{ - 3} \times  {5}^{2}  \times  {x}^{ - 6}  }  \bigg)^{2}  \\  \\  =  {( {5}^{3 + 3 - 2} {x}^{ - 3 + 6}  })^{2}  \\  =  {( {5}^{6 - 2}  {x}^{3} )}^{2}  \\  =  {( {5}^{4}  {x}^{3}) }^{2}  \\  =  {5}^{4 \times 2}  {x}^{3 \times 2}  \\  =  {5}^{8}  {x}^{6}  \\
