Ooh ok these are fun. So these triangles are similar, meaning they are in proportion. In triangle LMN, line LM is 21. To find the corresponding line on the other triangle, we need to find the corresponding letters in the names. Because L and M are the first two letters, we need to use the first two letter s in the other name, so FG. Line FG is 9, so our first proportion is 9/21

Answer:

SA = 384 in²

Step-by-step explanation:

Assuming we're finding surface area:

SA of top of large cube: 8(8) - 4(4) = 48 in²

SA of sides of large cube: 4(8)(8) = 256 in²

SA of exposed faces of small cube: 5(4)(4) = 80 in²

Total = 48 + 256 + 80 = 384 = ∑SA

it takes 1 hour longer to fly to st paul at 200 mi/h than it does to return at 250 mi/h. How far away is st.paul​
gtnhenbr [62]

Answer:

1000 miles

Step-by-step explanation:

We will use the distance equation to find the answer to this problem.

D = RT

Where

D is distance

R is rate

T is time

At 250 miles per hour, suppose it takes t hours to go to st. paul. Thus, we can write:

D = 250t

Now, at 200 mi per hour, it takes 1 hour longer, so the time is "t + 1", so we can write:

D = 200(t+1)

We can equate both and see:

250t=200(t+1)\\250t=200t+200

Now, we solve for t first:

250t=200t+200\\250t-200t=200\\50t=200\\t=\frac{200}{50}\\t=4

We want the distance of St. Paul, so we can use any equation. lets use the 1st equation:

D = 250t

we know t = 4

so

D = 250 * 4 = 1000 miles

Distance to St. Paul is 1000 miles

Determine if the three given side<br> lengths form a right triangle.<br> 10 cm, 15 cm, 20 cm
antiseptic1488 [7]

Answer:

It doesn't form a right triangle

Step-by-step explanation:

According to the Pythagorean theorem, the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.

a^2 + b^2 = c^2 by substituting the three values, 10, 15, and 20 you should get an equivalent value of the hypotenuse.

10^2 + 15^2 = 20^2

100 + 225 = 400

325 =/= 400

This is false.

Since this is not equivalent, it is NOT a right triangle.

Hope this helped :)
