Answer:

(D) 81 feet      

Step-by-step explanation:

From the figure drawn, it is given that AB is parallel to DE, in ΔABC and ΔCDE, we have

∠BAC=∠DEC(Alternate angles)

∠ACB=∠DCE(Vertically opposite angles)

Thus, by AA rule, ΔABC is similar to ΔCDE.

Since the line connecting from the whales to the sharks is parallel to the line connecting from the penguins to the fish tanks, the triangles shown in the figure are similar. Using the property of similar triangles.

Hope this helped!!!

Identify the sequence of transformations that maps ABCD to JKLM.
laila [671]

Answer:

The answer is below

Step-by-step explanation:

The question is not complete, no diagram is attached, but I would show how to solve it.

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

If a point A(x, y) is reflected across the x axis, the new point is at A'(x, -y).

If a point A(x, y) is reflected across the y axis, the new point is at A'(-x, y).

If a point A(x, y) is translated a units up and b units right, the new point is at A'(x + a, y + b).

If a point A(x, y) is translated a units down and b units left, the new point is at A'(x - a, y - b).

Slope intercept form of y=-1/7x+22/7
forsale [732]

This equation is already in slope intercept form.

Slope intercept form is y = mx + b, which is the form it is in now. However, if you would like it changed to standard form, you would multiply by the lowest common denominator and then rearrange as follows.

y = -1/7x + 22/7 -----> Multiply both sides by 7

7y = -x + 22 ------> Add x to both sides

x + 7y = 22

The variables x and y vary inversely. Use the given values to write an equation relating x and y. Then find y when x=−3.
-BARSIC- [3]

Answer:

xy-3x=40, x=5

x(y-3)=40

y-3=(40/x)

y=(40/x)+3

y=(40/5)+3

y=8+3

y=11
