Find the surface area of the regular pyramid.

Mathematics

Answer:

<h2>384mm</h2>

Step-by-step explanation:

The surface area of a square pyramid is 1/2 the product of its base perimeter & slant height.

SA = area of base + 1/2 (perimeter of base * slant height)

So, we can substitute 12 and 10 into this equation.

The area of the base is 12*12 (144). The perimeter of the base is 48mm.

144 + 1/2(48*10) = Surface Area.

144 + 240 = Surface Area.

384mm = Surface Area.

<em>Hope that helps :)</em>

How many of the 320 million Americans would you predict wear contacts lenses?​
Bess [88]

Answer:

40,640,000

Step-by-step explanation:

The way I solved this equation was by dividing 320,000,000 by 1,000 (to make smaller numbers). Then, I got 320,000. From here, I was able to multiply 320,000 by 127 (the number found in this specific study group) to get 40,640,000. Or, you could just multiply 320,000,000 by 0.127 (the decimal equivalent to 127/1000) to get the same answer. Please mark Brainliest if this helped :)

Hello,

\dfrac{\dfrac{x^2-9}{x+1}}{\dfrac{x^2-6x+9}{7x+7}}=7*\dfrac{(x-3)(x+3)*(x+1)}{(x+1)(x-3)^2}=7*\dfrac{x+3}{x-3}

A local hamburger shop sold a combined total of 437 hamburger and cheeseburgers on Thursday. There were 63 fewer cheeseburgers s
trasher [3.6K]
Let h represent hamburgers and c represent cheeseburgers. We can set up an equation:

h + c = 437

h + (h - 63) = 437

h + (h - 63 + 63) = 437 + 63

h + h = 500

2h = 500

2h / 2 = h

500 / 2 = 250

h = 250

250 hamburgers were sold.

To find how many cheeseburgers were sold, we subtract 250 - 63:

250 - 63 = 187

187 cheeseburgers were sold.

187 + 250 = 437

250 hamburgers and 187 cheeseburgers were sold on Thursday.
