Answer:

option D.

Step-by-step explanation:

average rate of change in steel production over the eight days=-0.15 tons per day

Step-by-step explanation:

The production rate of a steel factory is declining due to old machinery. Over the last eight days production has dropped by 1.2 tons.

Production is dropped by 1.2 tons, so its negative

Average rate of change = Change in production / number of days

Average rate of change = -1.2/ 8= -0.15

so sorry -0.15

PLZ HELP its Triangle Properties and where using the 45º-45º-90º Triangle Theorem and the 30º-60º-90º Triangle Theorem.
den301095 [7]

Answer:

The answer to your questions is below

Step-by-step explanation:

4.-

In a 45°-45°-90° triangle, the length of the legs are "x" and the length of the hypotenuse is x\sqrt{2}

Then, in this problem, the length of the leg is 7 then the length of the hypotenuse will be 7\sqrt{2}

5.- In a 30°-60°-90° triangle, the length of the hypotenuse is 2x, the length of the longer leg is x\sqrt{3} and the length of the shorter leg is x.

In this problem we have the length of the hypotenuse = 20 and find x.

                          2x = 20

                             x = 20/2

                             x = 10

          longer leg = xx\sqrt{3} = 10\sqrt{3}

6.- nonzero

7.- hypotenuse = 20 cm

     Find x

                         2x = 20

                           x = 20/2

                          x = 10

   Shoter leg = x = 10 cm

What is true about the sum of the two polynomials?<br> 6s^2t – 2st^2<br> 4s^2t – 3st^2
Snowcat [4.5K]
The sum is 10s^2t-5st^2. With two separate sections it’s a binomial, and the sum of the powers of the variables is 2+1=3, it has a degree of 3.
