See in the explanation

<h2>Explanation:</h2>

In this exercise, <em>we have the following points:</em>

$(0.8) \\ \\ (6.4)$

And <em>the following linear equations:</em>

$(1) \ y=-x+8 \\ \\ (2) \ y=\frac{3}{2}x+6 \\ \\ (3) \ y=-\frac{4}{5}x+4 \\ \\ (4) \ y=\frac{1}{2}x+8$

When plotting these graphs, we find the following facts:

We see the graph in the first figure below. The graph only passes through the point (0, 8)

This is the second graph below. The graph passes neither through point (0, 8) nor (6, 4)

This is the third graph below. The graph passes neither through point (0, 8) nor (6, 4)

This is the fourth graph below. The graph only passes through the point (0, 8)

So, <em>there is no any equation of the line that passes through the points (0.8) and (6.4) at the same time.</em>

A science teacher has a supply of 50% sugar solution and a supply of 80% sugar solution. How much of each solution should the te

mash [69]

How much of each solution should the teacher mix together to get 105 ML of 60% sugar solution for an experiment?

1. Look at how 60% is closer to the solution of lower concentration (50%). You can deduce that you will be mixing a higher volume of the 50% solution.

2. All 4 answers add up to 105ml.

3. The intuitive answer is the first option:
70 ML of the 50% solution and 35 ML of the 80% solution

4. Let's check whether point 3 is true.
70ml/105ml X 0.5 + 35ml/105ml X 0.8 = (35 + 28)/105= 63/105= 60% / 105 ml = 105ml of 60% sugar solution

Answer:

b = 6

Step-by-step explanation:

Cross multiply: 39(b) = (26)(9)

39b = 234

Divide both sides by 39

b = 6

Two circles, one of radius 5 inches, the other of radius 2 inches, are tangent at point P. Two bugs start crawling at the same t

lawyer [7]

Answer:

40 minutes

Step-by-step explanation:

The circumference of the larger circle is ...

C = 2πr = 2π(5 in) = 10π in

The bug navigates the circumference at 3π in/min, so will take

time = distance/speed = (10π in)/(3π in/min) = 10/3 min

to travel once around.

The circumference of the smaller circle is ...

C = 2πr = 2π(2 in) = 4π in

The bug navigates this circumference at 2.5π in/min, so will take

(4π in)/(2.5π in/min) = 8/5 min

to travel once around.

The bugs will meet at a time that is the least common multiple of these times. Both can be expressed in 15ths of a minute as ...

{50/15, 24/15}

Then the LCM of these will be ...

(1/15)LCM(50, 24) = (1/15)(50×24)/GCD(50, 24) = 1200/30 = 40

It will be 40 minutes before the bugs next meet at point P.

___

A graphing calculator can make use of the mod function to show when the bugs meet at point P (total is displacement of the two bugs from P is zero). It shows the meeting occurs after 40 minutes.
