At a dinner party, two desserts are being served. Six of the guests choose cheesecake, and eight of the guests choose apple pie.
Maslowich

Answer:

When six guests choose cheesecake and eight choose apple pie, the ratio is 6:8. If we use the same prompt but change 6 to 3 and change 8 to 4, the ratio becomes 3:4 with the pie graph looking exactly the same.

6:8 comes out to a total of 14 people

and 3:4 comes out to a total of 7 people

The two ratios are equivalent due to the graphs looking exactly the same as well as that 14 is double of 7.

Will give BRAINLIEST if right!
DiKsa [7]

To convert a number from scientific notation to standard form, consider 1.5625 x 10^4. First, focus on the exponential number, which is 10^4. Multiply the base number, which is 10, by itself the number of times indicated by the exponent, which is four. You would do that like this:

10 x 10 x 10 x 10 = 10, 000

Plug the product -- which is 10,000 -- into the original equation to get this:

1.5625 x 10,000 = 15, 625

Therefore, the standard form of this number is 15,625.

For a number in expanded form, convert the number, using basic addition. For example, consider the expanded number 10,000 + 2000 + 100 + 10 + 9. Add up these numbers to get the standard form. Your equation would look like this:

10,000 + 2,000 + 100 + 10 + 9 = 12,119

Therefore, the standard form of the number is 12,119.

What is the surface area of the triangular prism?
ryzh [129]

Answer:

135 square feet.

Step-by-step explanation:

A triangular prism. The rectangular sides are 8 feet by 2.5 feet, 8 feet by 6 feet, and 8 feet by 6.5 feet. The triangular sides have a base of 2.5 feet and a height of 6 feet.

The prism has two triangular faces and three rectangular faces.

So, the surface area of the prism will be

2(\frac{1}{2} \times 2.5 \times 6) + (8 \times 2.5) + (8 \times 6) + (8 \times 6.5)

= 15 + 20 + 48 + 52

= 135 square feet. (Answer)
