This is a lot of calculation.

So we know that the sum of angles for any heptagon is 900, because heptagon can be divided into five non-overlapping triangles and sum of angles of each triangle is 180.

Now you just add up all angles and simplify the equation:

900 = (6x - 8) + 120 + (7x - 64) + (5x - 4) + 135 + (3x + 31) + (4x + 15)

900 = <span>25x + 225

Now it's just regular algebra equation. You can solve for x:

675 = 25x

x = </span>27

So the value of x is 27

Owen had 3 different kinds of stickers that he wanted to put on paper. He put a bird sticker on every 30th paper, a sports stick
Semmy [17]
So the which page that will have the 3 sticker, we must solve the least common multiple of 30, 50, 60. <span>A common multiple is a number that is a multiple of two or more numbers. The common multiples of 3 and 4 are 0, 12, 24, ....</span>

<span>The least common multiple (LCM) of two numbers is the smallest number (not zero) that is a multiple of both.</span>

<span>so the least common multiple of 30, 50 and 60 is 300. so the page that will have 3 stickers is 300th page</span>

A beaker is completely filled with water
Tju [1.3M]

Answer:6.3 in.

Step-by-step explanation:

Given

Radius of sphere r=4\ cm

When ball is immersed in beaker, it causes the water to flowout of beaker which is collected in the conical vessel

Such that amount of water equivalent to sphere volume is collected in it.

volume of ball

V_s=\frac{4\pi }{3}r^3

V_s=\frac{4\pi }{3}\times 4^3

V_s=\frac{256\pi }{3}\ cm^3

Now volume of water collected is in shape of cone then volume of cone

V_c=\frac{\pi }{3}r^2h

and V_s=V_c

\frac{256\pi }{3}=\frac{\pi }{3}(4)^2\times h\ quad [\text{h=height of cone formed}]

h=4^2=16\ cm\approx 6.29\approx 6.3\ in.
