Answer:

B)14.14

Step-by-step explanation:

a square is made of 2 right triangles

the two legs of one right triangle are both 10 so

using Pythagorean theorem we get the square root of 10^2+10^2

this solves to the square root of (200)

which is ≈ 14.14...

I need help figuring out the coordinate planes of these points ASAP.
d1i1m1o1n [39]

<u>Given</u>:

The vertices of the quadrilateral WXYZ are W(2,4), X(4,2), Y(2,1) and Z(0,2)

The graph is rotated 90° about the origin.

We need to determine the coordinates of the quadrilateral W'X'Y'Z'

<u>Coordinates of the quadrilateral W'X'Y'Z':</u>

The rule to transform the coordinates 90° counter clockwise about the origin is given by

(x, y) \implies(-y, x)

Let us substitute the coordinates.

The coordinates of W' is given by

W(2,4)\implies W'(-4,2)

The coordinates of X' is given by

X(4,2) \implies X'(-2,4)

The coordinates of Y' is given by

Y(2,1) \implies Y'(-1,2)

The coordinates of Z' is given by

Z(0,2) \implies Z'(-2,0)

Therefore, the coordinates of the vertices W', X', Y' and Z' are (-4,2), (-2,4), (-1,2) and (-2,0) respectively.

2 A garden hose supplies 36 gallons of water in 3 minutes. Use a table or eq
Vilka [71]

Answer  ↣ 12 gallons per minute

Step-by-step explanation ↣ Ok I'm gonna use ratios because I can't draw a graph here.

Ok so if the garden hose supplies 36 gallons of water in 3 minutes, then the ratio is 36:3 because every 3 minutes the garden hose "sprays" 36 gallons.

To simplify this ratio, you need find the amount of water the garden hose supplies in 1 minute.

Well to get from 3 to 1, you have to divide by 3.

Do the same thing to 36. 36/3 equals 12.

So the final ratio is 12:1

This is the unit rate. The unit rate is when one variable is 1 unit (most of the time it is speed).

You can multiply 1 by any number and multiply 12 by the same number.

Here are some ratios...

m=minutes

g=gallons

1m:12g

2m:24g

3m:36g

4m:48g

5m:60g

Hope this helped!

BTW why do I sound like this I'm not a aesthetic person-
