On Tuesday, Karen finished all her chores in 3/4 of an hour. On Wednesday, she finished her chores in 5/12 of an hour. How much

IRISSAK [1]

1 hour = 60 minutes

Tuesday: 60 divided by 4 = 15. Karen did it 3/4 of a hour so we multiply 15 by 4 which is 45. 45 equals 45 minutes. On Tuesday, Karen finished her chores in 45 minutes

Wednesday: first we divide 60 by 12 which is 5. 5 would equal 5 minutes. now we multiply 5 by 5 which is 25. Karen finished her chores in 25 minutes.

Answer: Karen finished her chores 20 minutes faster on Wednesday than Tuesday.

Hope this helps!

Solve the system of equations. How many solutions foes the system have? Help pls :D

jenyasd209 [6]

Answer:

Infinitely Many Solutions

Step-by-step explanation:

Step-1: Re-write the equations into correct form.

=> 6x + 3y = 24

y = -2x + 8

=> 6x - 24 = -3y

-2x + 8 = y

Step-2: Multiply "-2x + 8 = y" by 3.

=> 6x - 24 = -3y

-6x + 24 = 3y

Step 3: Subtract or Add if needed

=> 0 = 0

Because we got a result 0 = 0, this means that the system has infinitely many solutions.

Hoped this helped.

brian, tim and kenny got paid a total of $240 for mowing neighborhood lawns . They split the money in the ratio of 5:9:10 . how

Yuliya22 [10]

Answer:

$50 for Brian

$90 for Tim

$100 for Kenny

Step-by-step explanation:

Let 5x = amt for Brian

9x = amt for tim

10x = amt for ken

5x + 9x + 10x = 240

24x = 240

x = 10

5x = 5(10) = $50 for Brian

9x = 9(10) = $90 for Tim

10x = 10(10) = $100 for Kenny

A rational function can have infinitely many x-values at which it is not continuous. True or False. If false, explain

sattari [20]

It is false since the rational function is discontinuous when the denominator is zero. But the denominator is a polynomial and a polynomial has only finitely many zeros. So the discontinuity points of a rational function is finite.
