6:15 is in ratio form..... If you mean fraction form, a ratio is equivalent to a fraction, so the answer is 6/15
Answer:
c. both
Step-by-step explanation:
Part (a)
<h3>Answer: 0.2</h3>
----------------------------------
Work Shown
It costs $15 to rent a bike for 3 hours. We can write the following ratio below
15 dollars : 3 hours
To represent the connection of the two concepts (dollars connecting with hours)
We want the "15 dollars" to turn into "1 dollar". This is because the phrasing "per dollar" really means "per 1 dollar".
Divide both sides of the ratio by 15 to achieve this goal.
15 dollars : 3 hours
15/15 dollars : 3/15 hours
1 dollar : 1/5 hours
1 dollar : 0.2 hours
0.2 hours : 1 dollar
So we get 0.2 hours per dollar.
As a side note, 0.2 hours = 0.2*60 = 12 minutes.
========================================================
Part (b)
<h3>Answer: 3.38</h3>
----------------------------------
Work Shown
27 pages : 8 minutes
27/8 pages : 8/8 minutes
3.375 pages : 1 minute
3.38 pages : 1 minute
I'm dividing both parts of the original ratio by 8 to turn "8 minutes" into "1 minute" (due to the phrasing "per minute"). Don't forget to round to 2 decimal places.
The Aanswer is Perpendicular bisector. Hope this will help you!
(a.) The triangles presented in this problem are congruent. We can prove this using the AAA (angle-angle-angle) theorem of similarity. This states that if all three angles of a triangle are equivalent then the sides of the triangles are proportional. We know that all three angles of these triangles are the same since the image shows angle A = angle P, and angle B = angle Q, therefore, angle C = angle R.
(b.) Now that we know the triangles are similar and the sides are proportional, we can simply take a ratio of the sides to solve for x.
(3x+6)/24 = 28/32
3x+6 = (28/32)(24)
3x = 21 - 6
x = 15/3
x = 5
