a sum of RS 500 is in the form of denominators of RS5 & RS 10..if the total no. of notes is 90 ,find the no. of notes of each type................ do it by process will be mark as best

Answers

Answer 1

Answer: let rs.5 denominations be x , then rs 10 denominations will be 90-x

then total amount 5x + 10(90-x) which is rs.500

5x + 10(90-x) = 500

900 - 5x = 500
400 = 5x
therefore x = 80
therefore no. of rs.5 is 80
no. of rs.10 is 90-x = 90-80 = 10

Second one is $4.82 because you are trying to find the unit rate.

Peggy completed 5/6 of the math homework and Al completed 4/5 of the math homework. Did Peggy or Al complete more of the math homework?

Answers

Answer:

Peggy completed more of the math homework than Al

Step-by-step explanation:

we have

Peggy completed $5/6$ of the math homework

Al completed $4/5$ of the math homework

we know that

In order to be able to compare fractions more easily it is recommended that both have the same denominator

Multiply $5/6$ by $5/5$

$5/6(5/5)=25/30$

Multiply $4/5$ by $6/6$

$4/5(6/6)=24/30$

$25/30> 24/30$

therefore

Peggy completed more of the math homework than Al

Peggy 5/6 x 5 = 25/30
Al 4/5 x 6 = 24/30

Peggy completed more of the math homework

NEED HELP! worth 10 points:)a house painting company charges $376 plus $12 per hour .Another painting company charges $280 plus $15 per hour. (a)how long is a job for which both companies will charge the same amount?(b) what will that cost be?

Answers

x equals number of hours
company 1: 376+12x
company 2: 280+15x
set them equal to each other to get the amount of hours
376+12x=280+15x >>> than subtract 280 from both sides
-280 -280 that equals
96+12x=15x than subtract 12x from both sides
-12x -12x
96=3x than divide the whole equation by 3
32=x
(a) 32 hours
and to get part b just plug the 32 into one of the equations
376+12(32)
376+384
760
(b) $760
if you plug it into the other equation you get the same answer so that means that the answer is correct
I hope this helps
