Answer:

P(blue) = .25

Step-by-step explanation:

We need to know how many marbles in the bag

3 blue marbles+ 4 green marbles+ 5 red marbles = 12 marbles

P ( blue) = blue / total = 3/12 = 1/4 = .25

Wo numbers are in the ratio of 2 to 3. If the smaller number is 18, the larger number is
Zarrin [17]
The simplified ratio is 2:3. Since the smaller number when it's not simplified is 18, let's divide 18 by 2 to get our factor.
18/2 = 9.
So we can multiply 9 by 3 to get the missing larger number.
9 x 3 = 27.
Your missing number is 27, hope this helps!

a survey conducted in a school showed that 65% of the students walked to school. The remaining students took buses to school. Th
Feliz [49]
I fear that there is an error copying your assignment.  
65% of the students walked.  Are all of the other students on buses?  Are there both public buses AND private buses?
Assuming that you need to know BOTH kinds of buses, try this:

65% of the students walked, so since 100% - 65% = 35% then this means that 35% of the students were on buses.
Since we know that there are 360 more walkers than bus riders, then one equation we know is:  65% of S = 360 + 35% of S  (let S = total # of students)
              .65 S     = 360 + .35 S
           <u> - .35 S   </u>  =     <u>   - .35 S</u>      Subtract .35 S from both sides
             <u> .30  S   </u> = <u> 360</u>                 Divide both sides by .30 (or .3)
                .30           .30
                      S   =  1,200  so we know that this is the total number of students, but that is not what was asked.  
They want to know how many are on buses and specifically how many are on public buses, if I read this correctly.
   Since the walkers = 65% of 1,2000 and we know of means TIMES, then
                                  .65 (1,200) =  780 walkers
 1,200 total students minus 780 walkers = 420 bus riders

Now, if there is not a misprint and we really have to figure out the public bus riders as compared to the private bus riders, then remember the ratio from above in the question:   4 bus: 3 public buses
Now if I read this right, that means that 3/4ths of the bus riders were on public buses
so 3/4 of 420 means 3/4 times 420  = 3 times 105 = 315 public bus riders (which coincidentally leaves 105 private bus riders, but since they are private we don't know much about them.  Ha-Ha..... I made a lame joke.)

So your answer is 315 public bus riders

The Barber are keeping track of their family energy costs. It costs the Barbers $0.16 per week to run their dishwasher. How much
rosijanka [135]

Answer:

It will cost them $8.32 to run their dishwasher for 52 weeks.

Step-by-step explanation:

With the information provided, you can say that the cost to run the dishwasher is equal to the cost per week for the number of weeks, which would be:

Total cost=$0.16*number of weeks

Since you want to determine the cost to run the dishwasher for 52 weeks, you can replace the number of weeks in the formula to get the answer:

Total cost=$0.16*52

Total cost=$8.32

According to this, the answer is that it will cost them $8.32 to run their dishwasher for 52 weeks.
