A curcular track is 1/4 completing each mile every 1/15 mile
dsp73

Answer:

s = 3.75 miles/hour

Step-by-step explanation:

Distance covered = 1/4 of a mile

Time taken = 1/15 of an hour

We need to find the speed of the track. We know that,

s=\dfrac{d}{t}\\\\=\dfrac{\dfrac{1}{4}}{\dfrac{1}{15}}\\\\=3.75\ mi/h

So, the required speed is 3.75 miles/hour.

Find the value of Y<br> .....
vekshin1

Answer:

y = 6 \sqrt{3}  \: units

Step-by-step explanation:

In order to find the value of y, first we need to find the length of the perpendicular dropped from one of the vertices of the triangle to its opposite side.

By geometric mean theorem:

Length of the perpendicular

=\sqrt{9\times 3}

=\sqrt{27}\: units

Next, by Pythagoras theorem:

{y}^{2}  =  {9}^{2}  +  {( \sqrt{27} )}^{2}  \\  \\  {y}^{2}  = 81 + 27 \\  \\  {y}^{2}  = 108 \\  \\ y =  \sqrt{108}  \\  \\ y =  \sqrt{36 \times 3}  \\  \\ y =  \sqrt{ {6}^{2}  \times 3}  \\  \\ y = 6 \sqrt{3}  \: units

Plz help<br>will give the brainliest<br>need step by step explanation​
ddd [48]

Answer:

A = 25 units²

Step-by-step explanation:

First, figure out where the lines intersect.

Let's start with x = 0 and y = x:

because x = 0, substitute x in y = x    

    y = 0 so the intersection point of these two lines is (0,0)

With, x + y = 10 (or y = 10 - x) and x = 0:

  substitute x again y = 10 - 0, so y = 10 and the intersection point is (0,10)

The last point has to be found by setting y = x and x + y = 10 (y = 10 - x) equal to each other: x = 10 - x

solve for x: x = 10 - x

                  2x = 10

                    x = 5

find y: y = 10 - 5

          y = 5 and the intersection point is (5,5)

Now that you have the vertices of the triangle, you can find the area. (0,0) and (0,10) are on the y-axis and has a length of 10 units; this is your base. To find the height, you need to picture the triangle on the coordinate plane. Point (5,5) lines up with the midpoint (0,5) of the side with (0,0) and (0,10). From this, you can see that the height is  5 units.

Use the triangle area formula: A = 0.5bh

A = 0.5(10)(5)

  = 0.5 × 50

A = 25 units²
