Answer:
First Place wins in 15 events
Second Place wins in 12 events
Step-by-step explanation:
Let
the number of events winning first place be "f"
the number of events winning second place be "s"
Total 27 swimming events, we can write:
First place wins is THREE MORE than 2nd place wins, so we can write:
Replacing 2nd equation in 1st equation, we can solve for "s":
We know
f = s + 3
so,
f = 12 + 3
f = 15
Thus,
<u>First Place wins in 15 events</u>
<u>Second Place wins in 12 events</u>
Answer: Choice A) $0.45
================================
Explanation:
Plug in d = 0 and you'll have A(d) = 0.45d+180 turn into A(0) = 180. This says that Terry is paid $180 even if he doesnt travel a single mile.
Now plug in d = 1. You should get A(1) = 180.45 as the result.
Subtract the results: 180.45 - 180 = 0.45
He has earned 45 cents or 0.45 dollars for traveling one mile
----------
A shortcut is to notice that the slope of the line is 0.45
It might help to view A(d) = 0.45d+180 as y = 0.45x+180. We see that the equation is in slope intercept form y = mx+b
m = slope = 0.45 tells us how much additional dollars Terry earns for each additional mile traveled
b = 180 = y intercept = starting amount of money Terry is paid, this amount does not change based on how many miles he travels.
Answer:
See below
Step-by-step explanation:
<em>Refer to attache</em>d
Since 40 oz is total
<u>The weight of each shape indicated in the picture and calculated as:</u>
- 40/2 = 20 oz
- 20/2 = 10 oz
- 10/2 = 5 oz
As each inch weights 1 oz, there must be 5 of each shapes included in the kit
