Answer:
84.14 square units, total
Step-by-step explanation:
Use the formulas for area of the figures you're interested in.
<u>Rectangle Area</u>
A = LW
<u>Circle Area</u>
A = πr^2
__
Your rectangle area will be ...
A = 5 × 14 = 70 . . . . square units
The area of a full circle with diameter 6 (radius = 6/2 = 3) will be ...
A = π × 3^2 = 9π
The area of a semicircle of that size is half that:
semicircle area = 9π/2 = 4.5π
Then the total area of the two figures is ...
70 + 4.5π ≈ 70 +14.14 = 84.14 . . . square units
Pauline's average speed for this trip is 64 km/hr.
<em><u>Explanation</u></em>
First we will convert each 'minutes' into 'hours' . So......
40 minutes =
and 23 minutes = 
Now, 
So, the distance traveled for first 40 minutes at 88 km/hr speed
,
the distance traveled for next 40 minutes at 75 km/hr speed
and
the distance traveled last 23 minutes at 49 km/hr speed 
So, <u>the total distance traveled </u>
She spends 17 minutes eating lunch and buying gas.
So, <u>the total time taken for the trip</u> 
Thus, Pauline's average speed for this trip = (Total distance / Total time)
<em>(Rounded to the nearest km/hr)</em>

Answer:
4 miles per hour
Step-by-step explanation:
Let the miles jogged be directly proportional to the hours taken hence we say that m=kh where m is miles, k is constant of proportionality and h is the number of hours. Making k the subject of the formula then
. Substituting miles jogged with 3.5 miles and hours with 7/8 hours as given then

Therefore, the constant of proportionality is 4 miles per hour
