Answer:

then r is parallel to s

Step-by-step explanation:

<3 = <11

The are same side interior angles

If same side interior angles are equal , then r is parallel to s

Answer:

A. rectangle, not a square.

Step-by-step explanation:

A right rectangular prism is a shape of a cube which is made up of 6 rectangular edges.

It has 4 vertical edges and 2 horizontal edges

The adjacent edges of the rectangular prism is at right angles

A plane intersects a right rectangular prism parallel to its base that is the parallel edges. The cross section formed by the plane would be the shape of the base as it is parallel to base and will intersect the the 4 vertical edges perpendicularly.

Thus, the shape of the cross section formed by the plane would be best described by a rectangle and not a square because the base is in the shape of a rectangle.

The figure representing the plane is shown below.

What is the factorization of 216x12 – 64?

GalinKa [24]

9514 1404 393

Answer:

Step-by-step explanation:

The correct factoring can be found by looking at the first exponent in the second set of parentheses.

The factorization of ...

(a^3 -b^3)

is ...

(a -b)(a^2 +ab +b^2)

Here, you have a=6x^4 and b=4, so the first term in the second parentheses is ...

a^2 = (6x^4)^2 = 6^2·x^(4·2) = 36x^8 . . . . matches the 3rd choice

You are going to meet a friend at the airport. Your experience tells you that the plane is late 70% of the time when it rains, b

Feliz [49]

Answer:

0.4

Step-by-step explanation:

Probability of rain = P(R)

Probability of late plane = P(L)

So, the probability of no rain = P(R')

Breaking it down

If it rains, 40% chance, P(R) = 0.4

That the plane would be late if it rains = 70% × 40%, that is, P(R n L) = 0.7 × 0.4 = 0.28, 28% of the total chance.

That the plane would be on time if it rains = 30% × 40%, that is, P(R n L') = 0.3 × 0.4 = 0.12, 12% of the total chance.

If it doesn't rain, 60% chance, P(R') = 1 - P(R) = 1 - 0.4 = 0.6

That the plane would be late if it doesn't rain = 20% × 60%, that is, P(R n L') = 0.2 × 0.6 = 0.12, 12% of the total chance.

That the plane would be on time if it doesn't rain = 80% × 60%, that is, P(R' n L') = 0.8 × 0.6 = 0.48, 48% of the total chance.

So, probability that the plane would be late = P(L) = P(R n L) + P(R' n L) = 0.28 + 0.12 = 0.4 = 40%
