5 0

Answer:

x = 48°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°, thus

x = 180° - (90 + 42)° = 180° - 132° = 48°

Find the volume of the figure.
jeka57 [31]

Hello from MrBillDoesMath!

Answer:

1283.3

Discussion:

Volume of figure =

volume of cone + volume of cylinder =

(1/3) Pi r^2 h       + Pi r^2 h                    =

(1/3) Pi (7)^2* 7   + Pi (7)^2 * 6  =

Pi * 7^2 (  (1/3) *7 + 6) =                      => using PI is approx 22/7

(22/7) * 7^2 ( 7/3 + 6) =

(22/7)* 49 (25/3) = 1283.3


Thank you,

MrB

Which pairs of points would result in a line with a rate of change of 2:1? Select all that apply.
Helen [10]

Answer:

Options A, C, D are true.

Step-by-step explanation:

We have to choose the pair of points from that given in the attached file which will result in a line with a rate of change i.e. slope of 2:1 i.e. 2.

A. The points are (-4,-11) and (-2,-7).

Then the slope of the joining line is \frac{-7-(-11)}{-2-(-4)} =2

B. The points are (5,6) and (-5,12).

Then the slope of the joining line is \frac{12-6}{-5-5} =-\frac{3}{5}

C. The points are (0,-3) and (-4,-11).

Then the slope of the joining line is \frac{-11-(-3)}{-4-0} =2

D. The points are (0,-3) and (5,7).

Then the slope of the joining line is \frac{7-(-3)}{5-0} =2

Therefore, options A, C, D are true. (Answer)
