marusya05 [52]
To get the answer first we have to find full numbers.
We can use proportion
2/3 ----------------------- 375
1 -------------------------- x
Crossmultiply now
2/3*x=375           /:2/3 
x=375: \frac{2}{3} 
x=375* \frac{3}{2}=562 - its the answer A)
Now we have to find how much were originally on the card.
To get the answer we can just multiply 562 times 1/4.

Tom earns ​$30 a week mowing lawns. He spends one-tenth of his earnings on lunch and one-fifth of his earnings on music. He save
-BARSIC- [3]

Answer: Tom saves $21

Step-by-step explanation: The monthly earning has been given as $30. The spendings are expressed as fractions of the total earnings. The expenses are as follows;

Lunch = one tenth of the earnings

Lunch = 1/10 x 30

Lunch = 30/10

Lunch = 3

Also he spends the following on music

Music = one fifth of the earnings

Music = 1/5 x 30

Music = 30/5

Music = 6

So he spends a total of 3 plus 6 which equals 9 dollars out of his earnings. His savings becomes

Savings = 30 - 9

Savings = 21

Therefore his savings is $21

max2010maxim [7]

Answer:

The probability of a person having a driving accident while intoxicated is 0.07

Step-by-step explanation:

Hi, well, let´s put this on a formula, I think it is the best way to explain it.

P(A+I)=P(A)+P(I)-P(AorI)

Where:

P(A+I) = Probability of having a driving accident while intoxicated.

P(A) = Probability of a person of having an accident.

P(I) = Probablity person being intoxicated.

P(A or I) = Probability of a person for being intoxicated or having an accident.

Therefore, things should look like this:

P(A+I)=0.12+0.32-0.37=0.07

So, the  probability of a person having a driving accident while intoxicated is 0.07.

Best of luck.
