a spherical tank 6 m in diameter can be filled with a liquid for $ 700, find the cost to fill a tank 24 m in diameter

$2800

Step-by-step explanation:

Since we know that a tank with a diameter of 6m costs $700 to fill, we just need to figure out the equivalent values for when the tank is 24m. To do so, since 24 is 4 times 6, we multiply the cost by 4 as well, to get $2800.

L = 34 - 0.5d

21 feet

Step-by-step explanation:

The initial water level ; 34

the amount is rises per day; 0.5

"L" is the water level,

"d" is the days passed.

In order to find the water level, one will have to multiply the amount the water rises each day, by the days passed. Then one will have to subtract that from the initial water level, hence the equation formed is the following;

L = 34 - 0.5d

Substitute in 26 for "d", to solve for the water level after 26 days.

L = 34 - 0.5(26)

L = 34 - 13

L = 21
