Answer:

200 square feet

Step-by-step explanation:

The formula for the lateral surface area of a square pyramid is $a\sqrt{a^2+4h^2}$ , where a is the side length and h is the height of the pyramid. The first step is therefore to find the height of the pyramid. Using the pythagorean theorem, you can find that it is $\sqrt{10^2-5^2}=5\sqrt{3}$ . Plugging in our known values into the equation, you get $10\sqrt{10^2+4(5\sqrt{3})^2}=10\sqrt{100+300}=10\cdot 20=200$ . Hope this helps!

Answer:

6. If the x intercept is a then (a,0) is on the line. If y-intercept is b then (0,b) is on the line. Now you have two points of the line and can get its formula. The slope between thse points is m=(0−b)(a−0)=−b/a. So the equation of line is y=mx+b=−bx/a+b. Now rearrange as y+bx/a=b divide by b to get y/b+x/a=1

Sadly I can't get eight right now but once I do I will edit this.

Advocard [28]

We have been given that Susan has a 12-inch board for constructing a wooden chair.The directions say to use a board that is 29 centimeters long. We are asked to determine if Susan's board is long enough to cut or not.

We know that 1 inch is equal to 2.54 cm.

Let us convert 12 inches into cm by multiplying 12 by 2.54.

$12\text{ inches}=12\times 2.54\text{ cm}$

$12\text{ inches}=30.48\text{ cm}$

Since 12 inches is equal to 30.48 centimeters and 30.48 is greater than 29, therefore, Susan's board in long enough to cut.
