Answer:
(3.5 , 3.5)
Step-by-step explanation:
Midpoint formula is x1+x2/2 and y1+y2/2
7 + 0/2 and 9 + (-2)/2
7/2 simplifies to 3.5
7/2 again simplifies to 3.5
so the midpoint coordinate is
(3.5,3.5)
<u>Answer-</u>
It will take 665640 minutes for Strobe to travel one full rotation around its sun.
<u>Solution-</u>
Assuming all the time units i.e days and minutes are same as that of Earth, we know that a single day consists of 24 hours and each hour has 60 minutes in it.
We have been given that, Planet Strobe travels one full rotation around its sun in approximately 462.25 days.
Number of hours that is equivalent to 462.25 days is,
As we know the relationship between hours and minutes, 11094 hours is,
Therefore,planet Strobe will take 665640 minutes to travel one full rotation around its sun.
Answer:
- total area is the total of the areas of each of the rectangular surfaces
- 67 units²
Step-by-step explanation:
Add up the surface areas of each of the 6 faces.
There are two top/bottom faces with the same area, two left/right faces with the same area, and two front/back faces with the same area. So you only need to figure the areas for 3 faces, then multiply that sum by 2. Of course the area of each rectangle is the product of its length and width. For length, width, and height dimensions L, W, and H, the total area is ...
A = 2(LW +WH +LH)
= 2(LW +H(L+W)) . . . . . I like this form because there's one less multiplication
= 2(5·4 + 1.5(5+4)) = 2(20 +13.5)
A = 67 . . . units²

<em>Comment on dimensions</em>
It does not matter which number you use for length, width, or height. The problem is symmetrical that way, so any of the dimensions can be called any of those things. You need to use the same number consistently for height (for example) once you have made the choice of which is which.
28 is the "100%" in this equation so all you need to do is take the number that is not the 100% and divide it by the 100% number. so
21/28
