Each cone of the hourglass has a height of 12 millimeters. The total height of the sand within the top portion of the hourglass

Harman [31]

The solution would be like this for this specific problem:

Volume of a cylinder = pi * r^2 * h

Volume of a cone = 1/3 * pi * r^2 * h

Total Height = 47

Height of the cone = 12

Height of the cylinder = 35

If the top half is filled with sand, then:

volume (sand) = pi * 4^2 * 36

volume (cone) = 1/3 * pi * 4^2 * 12

Total volume = 1960.353816 cubic millimeters

353816 / (10 * pi) = 62.4 seconds.

It will take 62.4 seconds until all of the sand has dripped to the bottom of the hourglass.

At the beginning of the week, Josh had 323232 computer games, 133\33, percent as many computer games as Peter had. By the end of

Ronch [10]

Answer:

$Josh =24$

$Peter = 32$

Step-by-step explanation:

Given

Beginning of Week

$Josh = 32$

$Josh = 133\% * Peter$

First, we calculate the amount Peter has at the beginning of the week

$Josh = 133\% * Peter$

Make Peter the subject

$Peter = \frac{Josh}{133\%}$

$Peter = \frac{32}{133\%}$

$Peter = \frac{32}{1.33}$

$Peter = 24$

When Josh gave out 25%.

The number (n) of computers is:

$n = Josh * 25\%$

$n = 32 * 25\%$

$n = 8$

This means that Josh gave out 8 computers.

So, the amount they both have is:

$Josh =32 - 8$

$Josh =24$

$Peter = 24+8$

$Peter = 32$

Decrease £843 by 91% rounded to 2 DP

34kurt

Answer:

Percent (%)' means 'out of one hundred':

p% = p 'out of one hundred',

p% is read p 'percent',

p% = p/100 = p ÷ 100.

91% = 91/100 = 91 ÷ 100 = 0.91.

100% = 100/100 = 100 ÷ 100 = 1.

Decrease number by 91% of its value.

Percentage decrease = 91% × 843

New value = 843 - Percentage decrease

Calculate the New Value

New value =

843 - Percentage decrease =

843 - (91% × 843) =

843 - 91% × 843 =

(1 - 91%) × 843 =

(100% - 91%) × 843 =

9% × 843 =

9 ÷ 100 × 843 =

9 × 843 ÷ 100 =

7,587 ÷ 100 =

75.87

Calculate absolute change (actual difference)

Absolute change (actual difference) =

New value - 843 =

75.87 - 843 =

- 767.13

Proof.

Calculate percentage decrease:

Percentage decrease =

91% × 843 =

91 ÷ 100 × 843 =

91 × 843 ÷ 100 =

76,713 ÷ 100 =

767.13
