Answer:

15pages

Step-by-step explanation:

there are 75 pages on her book

lilla read 1/5 of her book last week=1/5*75=15pages

this week she read 3times as much as she read last week=3*15=45pages

pages left to readcan be given as;

75-(15+45)

Calculate the average travel time for each distance, and then use the results to calculate. A 6-column table with 3 rows in the

BigorU [14]

The average travel time is simply the mean travel time between the given points

The average time that it takes for the car to travel the first 0.25m is 2.23s.
The average time to travel just between 0.25m and 0.50m is 0.9s.
Given the time taken to travel the second 0.25 m section, the velocity would be 0.28m/s.

<u>(a) The average time to travel the first 0.25m</u>

The time travel in the first 0.25m are: 2.24s, 2.21s and 2.23s.

So, the average time to travel is:

$Time = \frac{2.24s + 2.21s + 2.23s}{3}$

$Time = \frac{6.68s}{3}$

$Time = 2.23s$

<u>(b) The average time to travel just between 0.25m and 0.50m</u>

The time travel in the 0.50m are: 3.16s, 3.08s and 3.15s.

So, the average time to travel this distance is:

$Time = \frac{3.16s + 3.08s + 3.15s}{3}$

$Time = \frac{9.39s}{3}$

$Time = 3.13s$

The average time to travel between both distance is the difference between the average time of each distance.

So, we have:

$Average = 3.13s - 2.23s$

$Average = 0.9s$

<u>(c) The velocity in the second 0.25m section</u>

The distance and time are:

$Distance = 0.25m$

$Time = 0.9s$

So, the velocity is:

$Velocity = \frac{Distance}{Time}$

This gives

$Velocity = \frac{0.25m}{0.9s}$

$Velocity = 0.28m/s$

Calculate the area of a sector with radius 13m and angle 93

pashok25 [27]

Answer:

137.16

Step-by-step explanation:

we have a formular of the area of a sector:

S= pi*(its angle)/360*R^2

so apply to it

S= pi*(93/360)*13^2=137.16
