The ratio of the number of male lions to female lions in the animal reserve is 21:20 if there are 123 lions in the animal reserv

Katena32 [7]

ANSWER: 60 female lions

In the ratio there are 21 male lions and 20 female lions, in total 41 lions. Create a proportion relating the total number of lions in the ratio (41) and in the problem (123), and the number of female lions in the ratio (20) and in the problem (unknown).

20/41 = x/123

Cross multiply and solve

20(123)=41x

2460=41x

60=x

You have from 10 p.m. to 11:30 p.m. to do a project. a. At 11, what fraction of the time remains? b. At 11:20, what fraction of

EleoNora [17]

Answer:

a. $\frac{1}{3}$

b. $\frac{1}{9}$

Step-by-step explanation:

To solve it we must work in a single unit of time.

The unit we will use to solve it will be in minutes

So from 10 pm to 11 pm, it has been 1 hour (60 minutes) and from 11 pm to 11:30 pm has been half an hour (30 minutes)

Now the total minutes that have passed from 10 pm to 11:30 pm is

$60+30= 90$

A fraction tells us how many parts we have

In this case 90 minutes is what we want to divide:

a. At 11, what fraction of the time remains?

Let's think about it in the following way if 60 minutes have passed from 10 pm to 11 pm, at what fraction of 90 minutes does 60 minutes equal?

To solve it we use a simple rule of three

$90 \longrightarrow 1\\ 60\longrightarrow x \\ \\ x=\frac{(60)(1)}{90} \\ x=\frac{2}{3}$

This is the fraction of time that has past.

Now the fraction of time that remains is

$1-\frac{2}{3}=\frac{1}{3}$

b. At 11:20, what fraction of the time remains?

Let's think about it in the following way if 80 minutes have passed from 10 pm to 11:20 pm, at what fraction of 90 minutes does 80 minutes equal?

To solve it we use a simple rule of three

$90 \longrightarrow 1\\ 80\longrightarrow x \\ \\ x=\frac{(80)(1)}{90} \\ x=\frac{8}{9}$

This is the fraction of time that has past.

Now the fraction of time that remains is

$1-\frac{8}{9}=\frac{1}{9}$

Jack is currently driving into a headwind (17% decrease). if his normal mileage is 41 mpg, what will his car's mileage be in the

dimaraw [331]

By the decrease of 17% in the mileage of Jack's car, the new mileage is only 83% of the previous mileage. To get the current mileage, we multiply the mileage by the percentage. That is,
new mileage = (41 mpg)(0.83)
= 34.03 mpg
Thus, the car's mileage in the headwind is only 34.03 mpg.
