Answer:
AB ≈ 4.41
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos25° = = = ( multiply both sides by AB )
AB × cos25° = 4 ( divide both sides by cos25° )
AB = ≈ 4.41 ( to the nearest hundredth )
Answer:
Yes
Step-by-step explanation:
The driver completed his route 9 different times as recorded here: 44.2, 44.9, 46.1, 45.8, 44.7, 45.2, 45.1, 45.3, and 44.6. The goal of the company is for the driver to complete it within less than 0.5 mins of 45 mins. The driver failed to do this two times when they completed it in 44.2 mins and 46.1 mins. If you take an average of the bus drivers 9 runs it is 45. 1 mins. Overall the driver does complete most runs within 0.5 mins on average.
44.2+ 44.9 +46.1 +45.8+ 44.7+ 45.2+ 45.1+ 45.3+ 44.6 = 405.9
405.9 / 9 = 45.1
Answer:
<em>75-9d</em>
Step-by-step explanation:
<em>Hello,</em>
<em>The Answer to the question is 75-9d let me explain why,</em>
<em />
<em>you are asking, how much money is leftover. For me to get that I need to know that for every book it cost "d" dollars.</em>
<em>You know you have $75, and you need 9 books, we don't know how much they cost but we don't really need to. </em>
<em>75 - 9d</em>
<em>75 is the total. You need to subtract it by how many books your buying, 9.</em>
The books are d amount of dollars, so we put 9d so that we know that for every 1 book it cost d amount so technically 9 is the amount of books times d, how much 1 book costs
<em>Hope you can understand, I was having some trouble finding a way to explain it so my bad.</em>
<em />
<em>Also, I haven't done that in a while so sorry if I'm wrong</em>

Answer:
the slope is change in the independent variable divided by the change in the dependent variable. in this case 800-400/5-1 = 100
Step-by-step explanation:
change in independent variable = 800 - 400
change in dependent variable = 5 - 1 = 4
divide the change = 400/4 = 100.
Note, this can work with any values you use in the table and your answer remains constant
