The Distance between the 2 points is 15 units
9514 1404 393
Answer:
382 square units
Step-by-step explanation:
The central four rectangles down the middle of the net are 9 units wide, and alternate between 8 and 7 units high. Then the area of those four rectangles is ...
9(8+7+8+7) = 270 . . . square units
The rectangles making up the two left and right "wings" of the net are 8 units high and 7 units wide, so have a total area of ...
2×(8)(7) = 112 . . . square units
Then the area of the figure computed from the net is ...
270 +112 = 382 . . . square units

<em>Additional comment</em>
You can reject the first two answer choices immediately, because they are odd. Each face will have an area that is the product of integers, so will be an integer. There are two faces of each size, so <em>the total area of this figure must be an even number</em>.
You may recognize that the dimensions are 8, 8+1, 8-1. Then the area is roughly that of a cube with dimensions of 8: 6×8² = 384. If you use these values (8, 8+1, 8-1) in the area formula, you find the area is actually 384-2 = 382. That area formula is A = 2(LW +H(L+W)).
Let's callx = number of dimes.y = number of nickels.We must make a system of two equations with two incgonitas to solve the problem and find the solution, knowing that we have 50 coins and that between both they add $ 4.50.The result is x = 40, y = 10.I attach the solution to the problem.
Answer:
x=2
Step-by-step explanation:
Answer: It will be explained below. Basically, 463.846154 minutes in total to read the rest of the book, and she reads at 78 pages per 90 minutes, or 13 pages per 15 minutes.
Step-by-step explanation: Shryia read 78 pages in 90 minutes - she had read 480-402, which is 78. This indicates a fairly annoying-to-calculate rate of 78 pages every 90 minutes, which is annoying to calculate, but please bear with it. The quantity of remaining pages is 402, of course, and as such we can simply divide this by 78 pages/90 minutes.
1. 402 pages divided by 78 pages/90 minutes
2. 402 pages multiplied by 90 minutes/78 pages (flipped the fraction; 90 minutes is now the numerator.)
3. 402 multiplied by 90 minutes/78 (reduced and removed the "pages" from each.)
4. 36180 minutes/78 (multiplied 402 to 90.)
5. 463.846154 minutes (divided 36180 by 78).
I hope this provides some insights.
