A home builder wants to decorate the post at the bottom of a stairway. One way to do this is to glue a square-based pyramid to t
AysviL [449]

We have been given net of a pyramid. We are asked to find the total surface area of the pyramid.

The surface area of the pyramid will be area of base plus area of 4 triangular sides.

We have been given that base of pyramid is square, so area of base will be square of base side.

\text{Area of base}=(\text{10 in})^2=100\text{ in}^2

Let us find area of one triangular side.

\text{Area of triangle}=\frac{1}{2}\times \text{Base}\times\text{Height}

\text{Area of triangle}=\frac{1}{2}\times \text{10 in}\times\text{6 in}

\text{Area of triangle}=\text{5 in}\times\text{6 in}

\text{Area of triangle}=30\text{ in}^2

Now we will multiply area of one triangular face by 4 to find area of 4 triangular faces.

\text{Area of 4 triangular faces}=4\times 30\text{ in}^2

\text{Area of 4 triangular faces}=120\text{ in}^2

Total surface area of pyramid would be area of base plus area of 4 triangular faces.

\text{Total surface area of pyramid}=100\text{ in}^2+120\text{ in}^2

\text{Total surface area of pyramid}=220\text{ in}^2

Therefore, 220 square inches of copper sheet are needed to make one pyramid.

Please help me and explain
Svet_ta [14]
Well  slope means <span>a surface of which one end or side is at a higher level than another; a rising or falling surface.</span> So pretty much its just saying he had 6 litters used 4 of those litters and  had a remainder of 2.  So you can say the slope means that he was decreasing in litters by using 2 litters every 1 hour. I don know really if it´s correct so, sooopppeeerrrr sorry. :( :) bye

Solve the exponential function
nikklg [1K]

Answer:

See below.

Step-by-step explanation:

Just like 18, continue with 19-21. Solve for x by rewriting each equation in log form.

e^x = 4.9\\\\x = ln 4.9\\\\x = 1.59

When rewriting the form, the base of the exponent becomes the base of the log.
