Answer:
There are 42 quarters (and 6 dimes).
Step-by-step explanation:
The given ratio is 2:14. But this does not tell us how many dimes nor how many quarters we have. Instead, it's a ratio. Modify this by multiplying numerator and denominator by n and then find n:
Number of dimes 2n
----------------------------- = -----
Number of quarters 14n
Then the total number of coins is 2n + 14n =48, implying that:
16n = 48, or n = 3.
Then the number of dimes is 2(n) = 2(3) = 6, and that of quarters is 14(n) =
14(3) = 42.
There are 42 quarters (and 6 dimes). Notice how the total of 42 and 6 is 48.
Answer:
The correct order of the steps is CEABD ⇒ B
Step-by-step explanation:
Let us arrange the figures
To construct a bisector of an angle
First: Draw angle AOB
First step is figure C
Second: Place the pin of the compass on point O and draw an arc intersects the two sides of the angle OA and OB at points D and E
Second step is figure E
Third: Place the compass on point D and draw an arc in the interior of the angle
Third step is figure A
Fourth: without change the open of the compass place its pin on point E and draw an arc which intersects the arc drawn from point D at point C
Fourth step is figure B
Fifth: Draw a line from point A to point C, this line AC is the bisector of angle AOB
Fifth step is figure D
The correct order of the steps is CEABD
Part A: y-intercept = 12 miles
Part B: Find the average rate of change: 36 - 20/2 = 16/2 = 8 mph
This tells us that the bird can travel long distances.
Part C: 172 - 12 = 160 miles at a rate of 8 mph
160 mi ÷ 8mph = 20 hrs
Domain of function = 0 ≤ x ≤ 20
