What is the cosecant of angle C?
pishuonlain [190]
Cosecant = hypotenuse / opposite side    ( that is  1  / sine)
csc C =  AC / 8

AC  = sqrt (6^2 + 8^2) = sqrt 100 = 10

so cosecant of C is 10/8 = 1.25

A fish tank has a base area of 45cm2 and is filled with water to a depth of 12cm.If the height of the tank is 25cm, how much wat
stepladder [879]

Answer:

Step-by-step explanation:

v = 45 * 12

v = 540cm³

To fill the tank,

v = 45 * 25

v = 1,125cm³

I'm not quite sure what the exact question is so i'll answer both;

1.) The volume of water required to fill the tank from empty = 1,125cm³

2.) The volume of water required to fill the tank from it's current level is

1,125cm³ - 540cm³ = 585cm³

The sum of 3 times a number and 7 is 25
hammer [34]

Mathematically written:

3 * x + 7 = 25

3x + 7 = 25

3x = 25 - 7

3x = 18

x = 18 / 3

x = 6



Proof:

3 * 6 + 7 = 25

18 + 7 = 25

25 = 25 → both sides of the equation are equal, our answer is correct



Notes:

A number - Is an unknown number, called a variable, which in this case is substituted by the letter x.





Hope it helped,
