13.6 is 8% of what number

1 answer:

5 0

So we know that:

13.6 = 8%

Now we find what 1% will be, so we divide both sides by 8:

1.7 = 1%

Now multtiply both sides by 100:

170 = 100%

And the answer is 170
Hope it helped :)

Answer:

4082

Step-by-step explanation:

Given

The composite object

Required

The volume

The object is a mix of a cone and a hemisphere

Such that:

Cone

$r = 10cm$ ---- radius (r = 20/2)

$h = 19cm$

Hemisphere

$r=10cm$

The volume of the cone is:

$V_1 = \frac{1}{3}\pi r^2h$

$V_1 = \frac{1}{3}\pi * 10^2 * 19$

$V_1 = \frac{1900}{3}\pi$

The volume of the hemisphere is:

$V_2 = \frac{2}{3}\pi r^3$

$V_2 = \frac{2}{3}\pi 10^3$

$V_2 = \frac{2000}{3}\pi$

So, the volume of the object is:

$V = V_1 + V_2$

$V = \frac{1900}{3}\pi + \frac{2000}{3}\pi$

$V = \frac{3900}{3}\pi$

$V = 1300\pi$

$V = 1300 * 3.14$

$V = 4082$

Could someone please help and explain .

Law Incorporation [45]

Answer:

WXYZ = Ro(180°, (2, -3))(ABCD)

Step-by-step explanation:

A reflection across two perpendicular lines (y=-3, x=2) is equivalent to reflection across their point of intersection. That, in turn, is equivalent to rotation 180° about that point of intersection.

Your double reflection is equivalent to rotation 180° about (2, -3).

Find the volume of the figure below.

Taya2010 [7]

B- the volume of a cone is pi(r^2)(h/3) where r=radius and h= height.
When you plug in r &h you get pi(6^2)(19.6/3) =
pi(36)(6.53)=738.9

jim is standing beside apool.He drops a weight from 4 feet above the surface of the water pool.The weight travels a total distan

Taya2010 [7]

Treat the surface of the water as 0. The initial height of the weight was 4 ft above the surface of the water, therefore making it have an initial height of +4. If it travels 12 ft downward to hit the bottom of the pool, that means its height decreased by 12, so its falling is -12. To calculate the depth of the pool, use initial height minus drop distance, so 4 - 12. The depth of the pool is 8 ft.
