Hey!

Hope this helps....

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

For Question 2: 6+3+n=12

This is because we know that there is a combined total of 12, so it has to equal 12 (which cancels out C), we also know that the question is not saying anything that implys that we are multiply anything thing (which cancels out B, and D), so we are only left with A.) 6+3+n=12


For Question 4: 2 (Fraction 2 over 3)

This is because when we substitute all those choices in for y, we get...

2/(3*(3/8)) ~ 1.77778

2/(3*(5/12)) = 1.6

2/(3*(11/12)) ~ 0.727273

2/(3*(8/3)) = 0.25

^^^^ I got 8/3 from A (b/c) > ((A*c)+b)/c

(And we know 1/4 = 0.25)

The diagram shows a triangle.<br> x+19°<br> 6x–7°<br> 56°<br> What is the value of x?<br> x = <br> °
djverab [1.8K]

Answer:

x = 16.

Step-by-step explanation:

The 3 angles sum to 180 degrees so:

x + 19 + 6x - 7 + 56 = 180

7x + 68 = 180

7x = 112

x = 112/7 = 16.

2. A spy uses a telescope to track a rocket launched vertically from a launch pad 6 km away. The rocket travels upwards at a vel
grandymaker [24]

Answer:

The rate of change in distance between the spy and the rocket is 10.8 km/min,

or about 180 m/sec.

Step-by-step explanation:

At "Time=0" the rocket is 6km from the spy.

The rocket travels vertically 8km in about 0.37 minutes, calculated by 8km÷21.6km/min.

At that point, the rocket is 10 km from the spy., calculated by 6²+8²=10²

The difference is 4 kiilometers over 0.37minutes, about 22.2 seconds

Divide Distance by Time to get Rate:

4km/0.37min = 10.8 km/min

That is about 180 meters per second.
