61.80 miles per hour is Jen's speed.

Given:
170 miles
2 hours and 45 minutes

2 hours and 45 minutes is 2 45/60 in fraction and can be simplified to 2 3/4 in fraction. 
2 hours and 45 minutes is 2.75 in decimal.  

Let us use the decimal form for our time:

Speed = distance / time
            = 170 miles / 2.75 hours
Speed = 61.818 miles per hour

61.818 miles per hour rounded to the nearest tenth is 61.80 miles per hour.

Speed= distance /time
distnace=170 miles
t=2 hours + 45 minutes *(1 hora / 60 minutes=2 hours + 0.75 hours=2.75 hours.

Speed=170 mile / 2.75 hours=61.818...miles/hour≈61.8 miles/hour.

Solution: 61.8 miles/hour.

Here are the graphs of L(x) and R(x) what are the values of L(2) and R(2)
Sedaia [141]

Using the function graph given, it is found that:

  • L(2) = 7.
  • R(2) = 1.

When a piece-wise function is given, that is, a function that has <em>multiple definitions</em>, the numeric value at x when the definition changes is given by the closed circle.

  • For function L(x), when x = 2, the closed circle is at y = 7, hence, L(2) = 7.
  • For function R(x), when x = 2, the closed circle is at y = 1, hence, R(2) = 1.

Answer:

The volume of cone = Maximum holding of glass = 60 cube cm(cm^3)

Step-by-step explanation:

Cone formula:

v =  \frac{1}{3}  \pi \: r {}^{2} h

The radius is 3cm and Volume is 60cm^3.

if pi =~ 3 So the "h" is 6.66 cm.

"h" is distance from cone's head to its base.

The "H"( height of glass) = 6.66 + 7 = 13.6 =~ 14
