Write a fraction with a denominator of 4 to represent a distance that is less than 7/12 mile

Answers

So basically it's telling you to find a fraction with a denominator of 4 that is less than 7/12.

There are 2 possible answers, which are 2/4 (6/12) and 1/4 (3/12). Make sure to label 1/4 or 2/4 with mile, or it will probably be wrong.

Helena uses a mixture of compost and topsoil in her garden. She purchased a total of 10 cubic yards of compost and topsoil for $180. If compost costs $25 per cubic yard and topsoil costs $15 per cubic yard, how many cubic yards of topsoil did she purchase?A.)3
B.)4.5
C.)5.5
D.)7

Answers

Answer:

7 cubic yard

Step-by-step explanation:

Let the compost purchased be x cubic yard

And the topsoil purchased be y cubic yard

Hence

x+y=10 ----(A)

Also

Cost incurred in buying compost at a rate of $25 per cubic yards = 25x

Cost incurred in buying topsoil at a rate of $15 per cubic yards = 15y

Total cost incurred = 25x+15y=180

Diving whole equation by 5 we get

5x+3y=36 ----(B)

Multiply A by 3 and subtract it from B

5x+3y=36

- - -

3x+3y=30

_______

2x=6

x=3

Putting this value in A

x+y=10

3+y=10

y=10-3=7

Hence she purchased 7 cubic yards of topsoil.

Bill is in a class of 15 boys and 35 girls. 40% of the students in the class take the bus to school. How many students do not take the bus to school?

Answers

Answer:

30 students not take bus to school .

Step-by-step explanation:

As given

Bill is in a class of 15 boys and 35 girls.

Total number of students in the class = Number of boys + Number of girls

                                                              = 15 + 35

                                                              = 50

As given

40% of the students in the class take the bus to school.

40% is written in the decimal form.

= (40)/(100)

= 0.40

Number of students take bus to school = 0.40 × Total students in class.

                                                                  = 0.40 × 50

                                                                  =  20

Thus

Students not take bus to school = Total students - Number of students take bus to school

                                                      = 50 - 20

                                                      =  30

Therefore 30 students not take bus to school .
all\ students=girls+boys\n\nall\ students=15+35=50\n\n40\%\ of\ 50 \n40\%*50=0,4*50=20 \n\n50-20=30\n\n30\ students\ don't\ take\ the\ bus.
