8 0

Step-by-step explanation:

here will take the earth's surface as 0.

hence,

the first hole that Sally dug is 5 feet below the surface making its integer -5

the second hole Sally dug was 8 feet below the surface making its integer -8

therefore, the roses are closest to the surface.

Scorpion4ik [409]

The percentage value of the decimals are 475%, 99% and 1040% respectively.

Data;

4.75
0.99
10.4

<h3>Conversion of Decimals to Percentage</h3>

a) 4.75

To convert a decimal value to percentage, all we simply need to do is multiply that number by 100.

$4.75 * 100 = 475 \%$

b) 0.99

To convert this decimal value to percentage, we just need to multiply this number by 100.

$0.99 * 100 = 99 \%$

c) 10.4

To convert this decimal value to percentage, we just need to multiply this number by 100.

$10.4 * 100 = 1040\%$

A student on a piano stool rotates freely with an angular speed of 2.85 rev/s . The student holds a 1.50 kg mass in each outstre

Vlad1618 [11]

Answer:r'=0.327 m

Step-by-step explanation:

Given

$N=2.85 rev/s$

angular velocity $\omega =2\pi N=17.90 rad/s$

mass of objects $m=1.5 kg$

distance of objects from stool $r_1=0.789 m$

Combined moment of inertia of stool and student $=5.53 kg.m^2$

Now student pull off his hands so as to increase its speed to 3.60 rev/s

$\omega _2=2\pi N_2$

$\omega _2=2\pi 3.6=22.62 rad/s$

Initial moment of inertia of two masses $I_0=2mr_^2$

$I_0=2\times 1.5\times (0.789)^2=1.867$

After Pulling off hands so that r' is the distance of masses from stool

$I_0'=2\times 1.5\times (r')^2$

Conserving angular momentum

$I_1\omega =I_2\omega _2$

$(5.53+1.867)\cdot 17.90=(5.53+I_o')\cdot 22.62$

$I_0'=1.397\times 0.791$

$I_0'=5.851$

$5.53+2\times 1.5\times (r')^2=5.851$

$2\times 1.5\times (r')^2=0.321$

$r'^2=0.107009$

$r'=0.327 m$

In how many ways can we select 11 members of cricket players from 17 players

muminat

Answer:

12,376.

Step-by-step explanation:

The order in which they are chosen does not matter so this is a combination NOT a permutation.

That is 17C11

= 17! / (11! 6!)

= (17*16*15*14*13*12) / (6*5*4*3*2*1)

= 12376.
