Answer:
300
Step-by-step explanation:
The minimum and maximum operating temperatures for the engine are 200°F and 240°F respectively.
Average operating temperature =220°F
Absolute error = 20 °F
The minimum operating temperatures for the engine will be:
= 220°F - 20°F
= 200°F
The maximum operating temperatures for the engine will be:
= 200°F + 20°F
= 240°F

<h3>
Answer: Choice A</h3>
=========================================================
Explanation:
A proportional linear relationship is of the form y = kx
We can solve for k to get k = y/x.
Based on that, we can prove a table is a proportional linear relationship if and only if each column of x,y values divide to the same number.
Choice A shows that y/x = 2/8 = 1/4 for the first column; however, y/x = 8/16 = 1/2 for the second column. The outputs 1/4 and 1/2 not being the same indicates we don't have a constant k value for all of the columns. This is sufficient to show that table A is not a proportional linear relationship.
-------------
In contrast, table B is a proportional linear relationship because we have these four divisions that lead to the same value (1/8)
- Column One: y/x = 2/16 = 1/8
- Column Two: y/x = 4/32 = 1/8
- Column Three: y/x = 6/48 = 1/8
- Column Four: y/x = 8/48 = 1/8
Showing that k = 1/8 for table B. The equation here is y = (1/8)x. We can rule out choice B.
I'll let you check out tables C and D on your own, but you should find that a similar situation shows up as did with table B. This indicates tables C and D are also proportional linear relationships. We can rule out choices C and D.
Hey there Ag484p1stit,
Answer:
Rent = 25% x $3,400
= $850
Left now = $3,400 - $850
= $2,550
Transportation = 30% x $2,550
= $765.
She spends $765 on transportation.
Hope this helps :D
