Answer: 18 quarters & 15 pennies

Step-by-step explanation:Q + p = 33

0.25q + 0.01p = 4.65

p = 33 - q

0.25 q + 0.01 (33 - q) = 4.65

q = (4.65 - 0.33)/(0.24)

q = 18

p = 33 - 18 = 15

Grains of sand are very small, there being about 3000 grains in one cubic centimeter (cm3) of sand. A cm3 is a small cube measur

Anastasy [175]

Answer:

The value is $x = 3.000 * 10^9 \ grains$

Step-by-step explanation:

From the question we are told that

$1m^3 = 10^6 cm^3$

And that

$3000 \ grains \ of \ sand \ is \ in \ 1cm^3$

So the number of sand grain that is in $1m^3$ is mathematically evaluated as

$x = 3000 * 10^6 \ grains$

=> $x = 3.000 * 10^9 \ grains$
