Ann has 30% less money than Mary, and Jessica has 70% more than Mary. If the 3 of them have a (added up) total of $102, how much
Roman55 [17]
Let x be the amount of Ann money, y be Jessica's money and z Mary money. 
30% of z equates 0.3*z. 
Ann has 30% less than z so: x = z - 0.3z = 0.7z.
70% of z equates 0.7z. 
"Jessica has 70% more than Mary " we deduce the equation: y =z+0.7z= 1.7z.
Signe the total is $102, we deduce the equation x+y+z = 102. 
x=0.7z and y=1.7z then 0.7z+1.7z+z=102, therefore 3.4z=102 then 
z =102/3.4 = $30.
x=0.7*30= 21 and y=1.7*30=51.

Ann has $21, Mary has $30 and Jessica has $51.

PtichkaEL [24]
Given:
treasury bond = 40,000
brokers commission = 600
interest rate = 12$ p.a
interest paid semi-annually, january 1 and july 1.

Since the treasury bond was sold on June 1, its interest revenue will only be equal to 1 month ( June 1 to July 1).

12% / 12 months = 1% per month

40,000 * 1% = 400 interest revenue to be recorded on July 1.

lily bought 6 skirts and 5 coats for a total of $452.62. if lily sister bought 3 skirts and 5 coats for $289.36, what was the pr
Vikentia [17]

Answer:

$26.02

Step-by-step explanation:

Let the price of a skirt be A and that of coat be B

Iilly bought 6 skirts and 5 coats for a total of $452.62

That’s

6A + 5B = 452.62

Also, Lilly’s sister bought 3 skirts and 5 coats for $289.36

That’s

3A + 5B = 289.36

We now have two equations

1 . 6A + 5B = 452.62

2. 3A + 5B = 289.36

Subtract equation two from equation one

We have

3A = 163.26

Divide both sides by 3

3A/3 = 163.26/3

A = 54.42

A = $54.42

Now substitute 54.42 for A in either equations to get B the price of a coat

Using equation one, we have

6A + 5B = 452.62

6 x 54.42 + 5B = 456.62

326.52 + 5B = 456.62

Subtract 326.52 from both sides

326.52 - 326.52 + 5B = 456.62 - 326.52

5B = 130.1

Divide both sides by 5

5B/5 = 130.1/5

B = 26.02

= $26.02

A coat cost $26.02

Find the distance between (5, -2) and (7, -2)
Nuetrik [128]

Answer:

The distance is (2, 0)

Step-by-step explanation:

The first number is on the X axis. You move forward two places to get 7. The second number is on the Y axis, and you don't need to move anything so it stays the same. Hence the answer is a distance of two on the X axis.

A committee of three men and two women can be formed from a group of nine men and eleven women in how many different ways.
Marrrta [24]

Answer:

4620.

Step-by-step explanation:

The number of combinations of 3 men from 9

= 9!/(9-3)!3!

=  9*8*7/3*2*1

= 84 ways.

The number of combinations of 2 women from 11

= 11!/11-2)!2!

=  11*10/2*1

= 55 ways.

So the total number of ways  of men and women in the committee

= 84*55

= 4620.
