alexgriva [62]

Answer:11.5

Step-by-step explanation:

distance=6 2/5 + 2 3/4 + 2 1/3

d=(5x6+2)/5 + (4x2+3)/4 + (3x2+1)/3

d=32/5 + 11/4 + 7/3

d=(12x32+15x11+20x7) ➗ 60

d=(384+165+140) ➗ 60

d=689 ➗ 60

d=11.5

Helen [10]

Answer:

In 3 seconds the cup is filled with 105\ cm^3<u>.</u>

Step-by-step explanation:

Given:

2 seconds = 70\ cm^3 water

We need to find the percent of the cup that is filled with water after 3 seconds.

Solution:

Now Given:

The cup was filled at a constant rate.

First we will find the volume of water filled in the cup after 1 seconds.

2 seconds = 70\ cm^3 water

1 seconds = Volume of water filled in 1 second.

By Using Unitary method we get;

Volume of water filled in 1 second = \frac{70}{2}= 35\ cm^3

Now we will find the volume of water filled in the cup after 3 seconds.

1 second = 35\ cm^3 of water is filled

3 seconds = volume of water filled in the cup after 3 seconds

Again by using Unitary method we get;

volume of water filled in the cup after 3 seconds = 35 \times 3 = 105\ cm^3

Hence In 3 seconds the cup is filled with 105\ cm^3.

To find the percent of the cup filled with water after 3 seconds we would required the dimensions of the cup which is not available in the question.
