How to do you solve c/3=30/5
Viktor [21]

Answer:

c=18

Step-by-step explanation:

<em>To solve for c you need to do cross product property</em>

You have to multiply diagonally

So 3*30= 90

5*c= 5c

90= 5c

Now its a one step equation

Divide 90 by 5 =18

c= 18

A lighthouse has a shadow that is 36 feet long. Zara is 4 feet tall, and she is standing next to the lighthouse. Zara has a shad
xxTIMURxx [149]

At a particular time, objects and their shadows are proportionate.

Therefore, in figure,

\frac{AB}{FD}= \frac{BC}{DE} --- (1)

where AB is the height of the lighthouse, BC, its shadow and FD is the height of Zara and DE is her shadow.

From the given information,

BC = 36 feet

FD = 4 feet and DE = 3 feet

(1) becomes

\frac{AB}{4}= \frac{36}{3}

\frac{AB}{4}= 12

AB = 48

Hence, the height of the lighthouse is 48 feet.

Answer:

The correct answer is C. y = 3/4x - 12

Step-by-step explanation:

In order to find this, we must first note that the slope will be 3/4. We can tell this because parallel lines have the same slope. Next, we use that along with the point in point-slope form to find the equation.

y - y1 = m(x - x1)

y - -18 = 3/4(x - -8)

y + 18 = 3/4 (x + 8)

y + 18 = 3/4x + 6

y = 3/4x - 12

Determine the equation of the circle graphed below.
dsp73

9514 1404 393

Answer:

  (x +1)^2 +(y -3)^2 = 4

Step-by-step explanation:

The equation of a circle centered at (h, k) with radius r is ...

  (x -h)^2 +(y -k)^2 = r^2

The graphed circle is centered at (h, k) = (-1, 3), and has radius 2, so its equation is ...

  (x +1)^2 +(y -3)^2 = 4
