34. A motorist started a journey at 10.25a.m. and ended at 6.15 p.m. Calculate the time

GenaCL600 [577]

Write the times for each hour from start time:

10:25 am

11:25 am

12:25 pm

1:25 pm

2:25 pm

3:25 pm

4:25 pm

5:25 pm

6:25 pm

There are 8 hours between 10:25 am and 6:25 pm.

they finished at 6:15 which is 10 minutes before 6:25 ( 25-15 = 10)

10 minutes less than a full hour is 50 minutes ( 60 - 10 = 50)

8 hours - 1 hour = 7 hours

7 hours + 50 minutes = 7 hours 50 minutes total time.

While attending a school carnival, you estimate the ratio of children to adults as If there are 180 people at the carnival, abou

Karolina [17]

Answer:

180-n_c

Step-by-step explanation:

Given that the ratio of children to adults is 2:1.

Let $n_c$ and $n_a$ be the number of children and adults in the school carnival.

So, $\frac {n_c}{n_a} = \frac 2 1$

$\Rightarrow n_c = 2 n_a \cdots(i)$

Given that the total number of peoples in the carnival =180

So, $n_c + n_a = 180$

$\Rightarrow n_a = 180-n_c \cdots(ii)$

Now, from equations (i) and (ii), we have

$n_c = 2(180-n_c) \\\\\Rightarrow n_c = 360 -2 n_c \\\\\Rightarrow n_c +2n_c = 360 \\\\\Rightarrow 3 n_c = 360 \\\\\Rightarrow n_c = 360/3 = 120.$

Hence, the number of children in attendance is 120.
