Rus_ich [418]
Let's restate the given:

Height of cone = 70 cm
Radius = 15 cm

Now, first, let's find the volume of the cone through the formula V = πr²h/3
Substitute all data and you will get 16493.36 cubic centimeters. 

Now, to get how many days the container will be complete empty, you simply divide the volume of the cone by 500 cubic centimeters.

Days = 16493.36 cu cm/ 500 cu cm
Days = 32.99 or 33 days. 

Thus, the answer you're looking for is 33 days.

Step-by-step explanation:

problem 1.

1. 6y = 30

2. y = 5

3. 3x + 2(5) = 16

4. 3x+10=16

5. 3x=6

6. x=2

solution: (2,5)

problem 2.

1. x=7

2. 4(2)-2y=18

3. 28-2y=18

4. -2y= -10

5. y=5

solution (7,5)

problem 3

10x=10

x=1

7(1) +y =-2

y=-9

(1,9)

problem 4

0= -6

no solution

problem 5

-5/3 can be turned to a mixed number =-1 2/3
So can 18/11 = 1 7/11
10/4 = 2 2/4 or 2 1/2 simplified
And -3/3 as 1
This may make it easier to graph own the number line

Answer:

It's D

Step-by-step explanation:

2t - 30(\frac{1}{5}) = 20

2t - \frac{30}{1} (\frac{1}{5}) = 20

2t - \frac{30}{5} = 20

2t - 6 = 20

2t - 6 + 6 = 20 +6

2t = 26

\frac{2t}{2} = \frac{26}{2}

t = 13
