The answer for dividing 5/31 by 15/23 is 23/93
The division of fractions means dividing a fraction into further equal parts.
For example, If you have three-fourth of a pizza left, and you divided each slice into 2 parts you would get a total of six slices, but this would represent six-eighths of the total pizza.
Given that, find quotient 5/31 divided by 15/23.
5/31÷15/23
We know that, when we divide two fractions, we do the reciprocal of the second fraction and multiply it by the first fraction,
5/31×23/15
= 23 / 93
Hence, the answer for dividing 5/31 by 15/23 is 23/93

If A central angle has a measure of 2. 3 radians and the subtended arc length is 12 cm, then the radius of the circle is approximately 5.2 cm.
The formula relating the central angle, radius, and arc length of a circle is:
arc length = radius × central angle
We can use this formula to find the radius of the circle, given the central angle and arc length.
Substituting the given values, we get:
12 cm = r × 2.3 rad
Solving for r, we divide both sides by 2.3 rad:
r = 12 cm / 2.3 rad
Using a calculator, we get:
r ≈ 5.2174 cm
Rounding to the nearest tenth, we get:
r ≈ 5.2 cm

Therefore the car takes 2 s to reach a minimum height from the ground before rising again.
Step-by-step explanation:
Given that a roller coaster ride reach a height of 80 feet.
The height above the ground of the roller coaster is modeled by the function
h(t)=10t²-40t+80
where t is measured in second.
h(t)=10t²-40t+80
Differentiating with respect to t
h'(t)= 10(2t)-40
⇒h'(t)=20t-40
To find the minimum height we set h'(t)=0
∴20t-40=0
⇒20t =40
⇒t=2
The height of the roller coaster minimum when t=2 s.
The minimum height of of the roller coaster is
h(2)= 10(2)²-40.2+80
=40-80+80
=40 feet.
Therefore the car takes 2 s to reach a minimum height from the ground before rising again.
