Answer:

The water amount will be equal at 19.5 minutes

Step-by-step explanation:

Here, we want to find the value of t when the water level in both tanks will be equal

We simply proceed to equate both ;

That will be;

30t + 25 = -20t + 1000

30t + 20t = 1000-25

50t = 975

t = 975/50

t = 19.5 minutes

The only true statement is <em>"the orange 3 on the right is 1/10 of the value of the blue 3 on the left"</em>

<em />

This question bothers on place values.

<em />

Given the decimal value 89.033, the place value of the blue 3 on the left is the hundredth place (1/100) while the place value of the orange 3 is in the thousandth place(1/1000).

We need to<u> check which of the statement is correct. </u>

For the first option, the blue 3 on the left is 300 times the value of the orange 3 on the right;

  • 1/100 = 300(1/1000)
  • 1/100 = 3/10

Since 0.01≠0.3, hence the first option is wrong

For the second option, the blue 3 on the left is 100 times the value of the orange 3 on the right;

  • 1/100 = 100(1/1000)
  • 1/100 = 1/10

0.01≠0.1, hence the second option is wrong.

The blue 3 on the left is equivalent to the orange 3 on the right is also wrong since they are positioned in a different place

The orange 3 on the right is 1/10 of the value of the blue 3 on the left, is expressed as;

  • 1/1000 = 1/10(1/100)
  • 0.001 = 0.001

Hence the only true statement is <em>"the orange 3 on the right is 1/10 of the value of the blue 3 on the left"</em>
