Step-by-step explanation:

Find the total number of students

6+7+2+3+6+8+4+5=41

Then find the students that do not study chemistry

Question 5 of 13, Step 1 of 1

Georgia [21]

Answer:

It will take Mrs Chandler 18 hours 45 minutes or 18.75 hours to catch up Mr Chandler

Step-by-step explanation:

What we want to know here is that at how many hours will they have traveled same distance.

Let the total time taken by Mrs Chandler to catch up be x hours

Since Mr Chandler left 2.5 hours earlier , then the total time taken by him would be x + 2.5 hours

Now, we know that distance = speed * time

Since it’s same distance covered;

For Mr Chandler, his distance is calculated as 75(x + 2.5)

For Mrs Chandler, her distance is calculated as 85x

We equate both since they are equal;

75(x + 2.5) = 85x

75x + 187.5 = 85x

85x -75x = 187.5

10x = 187.5

x = 18.75 hours or 18 hours 45 minutes

A prize was awarded to 24 women and 1130 men. a. What fraction of the prize winners were women? b. What fraction were men?

Brums [2.3K]

a) The fraction of women is $\frac{12}{577}$

b) The fraction of men is $\frac{565}{577}$

Step-by-step explanation:

In this part of the problem, we are asked to find what fraction of the prize winners are women.

We have:

$w=24$ (number of prizes awarded to women)

$m=1130$ (number of prizes awarded to men)

First of all, we calculate the total number of prizes awarded:

$p=w+m=24+1130=1154$

Now we find the fraction of prize winners who were women, which is given by:

$p(w) = \frac{w}{p}=\frac{24}{1154}$

And we can simplify by dividing both numerators and denominators by 2,

$p(w)=\frac{24}{1154}=\frac{12}{577}$

The total number of prizes awarded is

$p=1154$

The number of prizes assigned to men is

$m=1130$

Therefore, the fraction of prize winners who were men is

$p(m)=\frac{m}{p}=\frac{1130}{1154}=\frac{565}{577}$

where we simplified the fraction by dividing both the numerator and the denominator by 2.
