A rectangular tile has a decorative pattern of 3 equal-sized squares, each of which is divided into 2 same-sized triangles. If M

arnie uses 36 of these tiles on the wall behind her kitchen stoves, how many triangles are displayed?

72 triangles will be displayed I believe....

All you do is multiply 2 times 36 and you get 72. Because there are 2 triangles in one square, so 2*36.

Hope this Helps!

Ok, so there are 36 rectangle tiles which have three squares in each one that has two triangles in each so... 36 x 3 = 108
=============================================================
so there are 108 squares, now you multiply by 2 to get the triangles, which is 108 x 2 = 216 :)
=============================================================
Thats your answer! hope i helped :)

An object is propelled upward from the top of a 300 foot building. The path that the object takes as it falls to the ground can
serg [7]

Answer:

As per the statement:

The path that the object takes as it falls to the ground can be modeled by:

h =-16t^2 + 80t + 300

where

h is the height of the objects and

t is the time (in seconds)

At t = 0 , h = 300 ft

When the objects hit the ground, h = 0

then;

-16t^2+80t+300=0

For a quadratic equation: ax^2+bx+c=0         ......[1]

the solution for the equation is given by:

x = \frac{-b\pm \sqrt{b^2-4ac}}{2a}

On comparing the given equation with [1] we have;  

a = -16 ,b = 80 and c = 300

then;

t= \frac{-80\pm \sqrt{(80)^2-4(-16)(300)}}{2(-16)}

t= \frac{-80\pm \sqrt{6400+19200}}{-32}

t= \frac{-80\pm \sqrt{25600}}{-32}  

Simplify:

t = -\frac{5}{2} = -2.5 sec and t = \frac{15}{2} = 7.5 sec

Time can't be in negative;

therefore, the time it took the object to hit the ground is 7.5 sec

 For the equation 2n - 3 = 7
Stells [14]

Answer:

The variable is n

The coefficient is 2

And the solution to n is 10.

Step-by-step explanation:

The number in the equation is the variable. The coefficient is the number before the variable. And a number next to a letter means you multiply. So 2*5=10 10-3=7

PLEASE HELP!!
Radda [10]

Answer:

C.) 2\sqrt{34}

Step-by-step explanation:

<em>You must use the pythagorean theorem</em>

the distance on the x axis (or a) is 6

the distance on the y axis (or b) is 10

6^{2}  + 10^{2} = 136

\sqrt{136} = 2\sqrt{34}
