Dion is laying brick down to make a patio. He plans for the patio to be 8.75 feet by 14.8 feet. He orders enough brick for 135 square feet. Which statement about the amount of brick is correct? Dion estimated correctly by rounding up. He ordered enough brick. The exact area is 129.5 square feet. Dion estimated correctly by rounding down. He ordered enough brick. The exact area is 129.5 square feet. Dion did not estimate correctly by rounding up. He did not order enough brick. The exact area is 129.5 square feet. Dion did not estimate correctly by rounding down. He did not order enough brick. The exact area is 129.5 square feet.

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)

the answer to your question is b.

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
