Inessa [10]3 years ago
4 0

Answer:

Step-by-step explanation:

-50 = -5x - 3(5x + 15)           {Use distributive rule}

-50 = -5x  + 5x *(-3) + 15*(-3)

-50 = -5x - 15x - 45         {Combine like terms}

-50 = -20x - 45     {Add 45 to both sides}

-50 + 45 = -20x

-5   = -20x         {Divide both sides by -20}

-5/-20 = x

1/4 = x

Find the size of angle YZX
Tasya [4]

Answer:

21.001 cm

Step-by-step explanation:

The diagram shows right triangle with

Hypotenuse ZY = 22.3 cm

Leg XY = 7.5 cm

By the Pythagorean theorem,

XY^2+XZ^2=ZY^2\\ \\7.5^2+XZ^2=22.3^2\\ \\XZ^2=22.3^2-7.5^2\\ \\XZ^2=(22.3-7.5)(22.3+7.5)\\ \\XZ^2=14.8\cdot 29.8\\ \\XZ^2=441.04\\ \\XZ=\sqrt{441.04}\approx 21.001\ cm

You work in a chemical lab. Last quarter, you successfully completed an average of about 5 chemical analyses per day. This quart
Kryger [21]

Answer: 60%

Step-by-step explanation:

Since, According to the question,  Last quarter, we successfully completed an average of about 5 chemical analyses per day.

Therefore initially our average = 5 chemical analyses per day.

Again, From the question, This quarter, we have increased this average to about 8 per day.

Therefore New average =chemical analyses 8 per day

Thus, Percentage change in the average = (Initial average - New average)×100/ initial average  

= \frac{8-5}{5} \times 100

= \frac{3}{5} \times 100

= 60 %

Therefore, Percentage change in the average=60 %
