15. A cylindrical glass 10 cm tall and 8 cm in diameter is filled to 1 cm

ANTONII [103]

Answer:

No. The new height of the water is less than the height of the glass(6.33 cm<10 cm)

Step-by-step explanation:

-For the water in the glass to overflow, the volume of the inserted solid must be greater than the volume of the empty space or the ensuing height of water >height of glass.

#Volume of the golf ball:

$V=\frac{4}{3}\pi r^3\\\\=\frac{4}{3}\pi \times 4^3\\\\\approx 268.08\ cm^3$

#The volume of the water in the glass:

$V=\pi r^2 h\\\\=\pi \times 4^2\times 10\\\\\approx 50.27\ cm^2$

We then equate the two volumes to the glass' volume to determine the new height of the water:

$V=\pi r^2h\\\\(206.08+50.27)=\pi r^2 h\\\\h=318.35/(\pi \times 4^2)\\\\=6.33\ cm$

Hence, the glass will not overflow since the new height of the water is less than the height of the glass(6.33 cm<10cm).

The angles measures x and 4x are complementary angles. Which is the value of x?

Hitman42 [59]

Answer:

The angles measures x and 4x are complementary angles. The value of x is 36 degrees

Solution:

Given, two angles are x and 4x

We have to find the value of above given x

We are also given that, given two angles are complementary angles for each other

So, we know that, sum of any two complementary angles will always be equal to 180 degrees

Then, in the problem given,

$x+4 x=180 \rightarrow 5 x=180 \rightarrow x=\frac{180}{5} \rightarrow x=36$

Hence the angles measures x and 4x are complementary angles. The value of x is 36 degrees
