on a 15 hour trip, Rob drove 35% of the time and Mark drove the reminder of the time. how many hours did Mark dive?

Answer:

B. None

Step-by-step explanation:

We are given the angles of a triangle as 66°, 66° and 66°

In order for these angles to construct a triangle, the sum of the three angles must be 180°.

So, we get that,

66° + 66° + 66° = 66° + 132° = 198°

Since, the sum of the angles is not 180° .

Therefore, no triangle can be drawn using the angles 66°, 66° and 66°.

Hence, option B is correct

Answer:

7

Step-by-step explanation:

Ms Smith has 28 sixth graders and 35 seventh graders

she wants to break them down into groups with each group having the same number of students from each grade

for this we have to find the highest common factor of 28 and 35 to see by which both 28 and 35 are divisible by

factors of 28 and 35 are as follows

28 - 1,2,4,7,14,28

35 - 1,5,7,35

the highest common factor both numbers is 7

therefore Ms Smith can break them down into 7 groups

each group will have

28 / 7 = 4 sixth graders

35 / 7 = 5 seventh graders

so each group will have 4 sixth graders and 5 seventh graders

so in each group there will be 4 + 5 = 9 students

she will break them down into 7 groups

each group has 9 students
