Two parallel lines are crossed by a transversal what is the value of A?
gulaghasi [49]

Answer: 63 degrees (second choice)

The two angles shown are corresponding angles. They are both on the bottom side of their adjacent parallel line, and at the same time, they are also on the left side of the transversal line. This is why they are corresponding angles.

Corresponding angles are congruent if you have a set of parallel lines like the diagram shows. So that's why a = 63.

A coffee mixture has beans that sell for $0.20 a pound and beans that sell for $0.68. If 120 pounds of beans create a mixture wo
atroni [7]
Let x be the number of pounds of the $1.35 beans. The cost of those beans is $1.35 * x, or 1.35x. 
<span>Let y be the number of pounds of the $1.05 beans. The cost of those beans is $1.05 * y, or 1.05y. </span>
<span>We know that 120 pounds of the mix sells for $1.15/pound, for a total of 120 * 1.15 = $138. </span>

<span>x + y = 120 </span>
<span>1.35(x) + (1.05)y = 138 </span>

<span>We can rewrite the first as </span>
<span>x = -y + 120 </span>

<span>Now we can substitute (-y + 120) in for (x) in the second equation, because we just proved they're equal. </span>

<span>1.35(x) + 1.05(y) = 138 </span>
<span>1.35(-y + 120) + 1.05y = 138 </span>
<span>-1.35y + 162 + 1.05y = 138 </span>
<span>-0.3y + 162 = 138 </span>
<span>-0.3y = -24 </span>
<span>y = 80 </span>

<span>And since x + y = 120, that means x = 40. </span>

<span>Check: </span>
<span>40 pounds of x at $1.35 costs 40 * 1.35, or $54. </span>
<span>80 pounds of y at $1.05 costs 80 * 1.05, or $84. </span>
<span>Do those add up to our target total, according to the question, of 120 * 1.15 = $138? </span>

scoray [572]

Answer:

Answer+Step-by-step explanation: 2019 game of the year award limited edition.

Step-by-step explanation:

This is all about carefully examining the slope. If you look carefully you will notice B curves in at the top just a little more than A so the first one is correct.

The second one is obviously not true.

The third one is disproved by the first.

The fourth one is correct as C is the peak and has little to no drop or rise.

The 5th one is correct, after spending several minutes examining it with 200%+ zoom I will tell you that it is correct B and D are the same.

I'm not 100% sure but I'm probably 95% sure that The 6th one is incorrect and A is changing height faster than D.
