Answer:
54
Step-by-step explanation:
its a sequence. they are multiplying by 3 each time.
So this triangle is considered a "special triangle". The 30-60-90 triangle rule states that if the short leg is n, then the hypotenuse is 2n and the long leg is n√3.
In this case, since the short leg is 7, x = 14 and y = 7√3. The correct answer that has this is B.
Solid A because when u calculate it, it’s shows it’s bigger then Solid B
You are wrapping a gift box. The length of ribbon = length + width + height of box.
<u>Solution:</u>
Given, You are wrapping a gift box.
You want to tie a ribbon around the box, so that whenever the ribbon intersects an edge of the box, its distance to the nearest corner is 1/3 the length of the box.
We have to find how long must the ribbon be?
The figure of this problem is attached below
Now, assume we started to tie at one edge, then next we can tie at straight parallel edge, we can continue till our process ends.
Then, total length of the ribbon = length of box + width of box + height of box.
Hence, the length of ribbon = length + width + height of box.
7) BC + CD = BD
(4x - 29) + (5x-9) = 7x -10
9x - 38 = 7x - 10 (when you transpose you change the sign)
9x - 7x = - 10 + 38
2x = 28
x = 14
8) BD = BC
5x - 26 = 2x + 1
5x - 2x = 1 +26
3x = 27
x = 9
if x = 9, then BC = 2x + 1 = 2(9) + 1 = 19
or
AB = AC - BC
AB = 43 - 19
AB = 24
