Suppose A, R, and B are collinear on AB, and AR:AB= 1/5. What are the coordinates of R?
AfilCa [17]

Answer:

R(1.6, 0)

Step-by-step explanation:

Use the formula, (x, y) = (x_1 + k(x_2 - x_1), y_1 + k(y_2 - y_1)) to find the coordinates of point R, that partition the lie segment AB into the ratio 1/5.

Let,

A(1, -1) = (x_1, y_1)

B(4, 4) = (x_2, y_2)

Thus, plug in the values as follows:

R(x, y) = (1 + \frac{1}{5}(4 - 1), -1 + \frac{1}{5}(4 -(-1))

R(x, y) = (1 + \frac{1}{5}(3), -1 + \frac{1}{5}(4 + 1)

R(x, y) = (1 + \frac{1}{5}(3), -1 + \frac{1}{5}(5)

R(x, y) = (1 + \frac{3}{5}, -1 + \frac{5}{5})

R(x, y) = (\frac{5 + 3}{5}, -1 + 1)

R(x, y) = (\frac{8}{5}, 0)

R(x, y) = (1.6, 0)

The coordinates of point R, are (1.6, 0)

A school is taking a field trip with 195 students and 10 adults. Each bus can hold at most 40 students. We need to determine the
Alex777 [14]

Answer:

40n>195+10

n>5.125

Step-by-step explanation:

The equality must satisfy the following:

A total of 195 students and 10 adults with 40 students per bus at most.

If the students it can take is at most 40, we must consider the adults as well. This maximum excludes the adults so therefore the actual amount of students must be less the 40 to allow adults on the bus as well.

40n>195+10

We can solve for n:

40n>205

n>5.125

The number of buses need for this trip must great than 5.
