Answer:

86.33 square micrometers

Step-by-step explanation:

A silicon wafer is textured to minimize light reflection. This results in a surface made up of square pyramids. Each triangular face of one of the pyramids has a base of 5 micrometers and a height of 5.6 micrometers. Find the surface area of the pyramid, including the base.

The formula for the Surface Ares mma is given as :

A=a² + 2a √a²/4+ h²

a = base edge = 5 micro meters

h = height = 5.6 micro meters

=5²+2× 5 × √5²/4+ 5.6²

= 86.32699 square micrometers

≈ 86.33 square micrometers

Complete the statement If x/7 = 5/3, then x+7/7 =?
lawyer [7]
Lets get started :)

\frac{x}{7} = \frac{5}{3}
We can cross multiply, to find the value of x
3x = 7 x 5
3x = 35
We have to divide by 3 on either sides to isolate x
\frac{3x}{3} =  \frac{35}{3}
3 and 3 cancels out

x = \frac{35}{3}

Then, x + \frac{7}{7}  ( 7 divided by 7 is 1)
\frac{35}{3} + 1   = \frac{38}{3}

AREA OF CIRCLES HELP PLS​
Lera25 [3.4K]

Answer:

432 ft²

Step-by-step explanation:

First lets find radius (r);

r = d/2

r = 24/2

r = 12

Now let's find the area;

A = π(12)²

A = 3(144)

A = 432 ft²

Hope this helps!

Give a example of two fractions with the quotient of 5/12
olasank [31]
Poorly phrased question, but the general answer is 5k/(12k), where k <span>∈ Z (i.e. k is an integer).

So, 5/12 and 10/24.</span>
