Mathematics
1 answer:
alexgriva [62]3 years ago

Answer:

15.8 (15/8)

Step-by-step explanation:

First, we turn the mixed numbers into fractions by multiplying the whole number by the denominator and this answer into the numerator:

2 1/2=5/2

1 1/3=4/3

now to divide, we keep the first fraction, change the divide to a multiply, and then flip the second fraction:

5/2·3/4

Now, simply multiply:

5/2·3/4=15/8 (15.8 if you need a decimal)

And you have your answer! hope this helped!

Marianna [84]

Answer:

a.4845ways.

b. 14535ways.

c. 3990ways

d. 1140ways

Step-by-step explanation:

Given data:

No of flavors available to customers = 20.

Solution:

This is permutation and combinations problem,

(a) how many ways can the customers choose 4 different ice creams if they are all of different flavors.

20C4

= n!/(n-k)!)k!

= 20!/(20-4)!)4!

= 20!/(16)!)4!

= 4845ways.

b) are not necessarily of different flavors

Let’s say any two same flavors can be chosen.

20C4 * 3!/2!

= 4845 * 3

= 14535ways.

c) contain only 2 or 3 flavors.

= 20C3 * 3!/2!

= 1140 * 3

= 3420

20C2 * 3

= 190 * 3

= 570.

No of 2 or 3 different flavors

= 3420 + 570

= 3990ways.

d) contain 3 different flavors.

20C3

= n!/(n-k)!)k!

= 20!/(20-3)!)3!

= 1140ways.

Vaselesa [24]

Let m and h represent hours Mai spends mowing and hauling, respectively. Then (m+h) will be the number of hours Priya spends babysitting. In order for their earnings to be equal, we must have  

 7m +14h = 8.40(m+h)

 Subtract 7m+8.40h:  5.60h = 1.40m

 Divide by 1.40:  m = 4h

Then the total number of hours worked by either person is

 m + h = (4h) +h = 5h

When only whole numbers of hours are worked, the smallest number of hours that will make earnings equal is 5h, with h=1, or 5 hours. In that time, each will earn 5×$8.40 = $42.

Therefore, each of them must work 5 hours and earn $42 before they go to the movies and Mai will work 4 hours mowing and 1 hour hauling.
