First we need to find a common denominator
=
now we can add them
+
=
1. count how many sig figs are in the number with least sig figs
2. multiply
3. cut the result off at the number of sig figs on top
15.05 has 4 sig figs
341.2
C
To solve the problem we will use this equation where,
d will be distance.
x is the speed of the plane without tailwind.
y is the speed of the wind affecting the plane.
Going to Philadelphia the speed of the plane affected by wind will be x-y=220 miles/hr
Coming back with a tailwind, the speed of the plane will be x+y= 280 miles/hr.
since time = distance / speed, t1 =d/220 and t2 = d/280
and since the total time traveled is 6.5hrs
d/220 + d/ 280 = 6.5hrs
d = 800.8 miles x 2 (back and forth trip) the answer is 1601.6 miles
So that is area of rectangle-1/2areacircle
so
areacircle=pir^2
r=5
1/2pir^2=1/2pi5^2=25pi/2=12.5pi
arearectangle=lw=12*5=60
unshaded=60-12.5pi=20.75 square feet
round
20.8 square feet
Answer:
5.4
Step-by-step explanation:
To find the distance between each pair of points, we use the distance formula, which is:
d = 
So we have
When we plug in the values into the formula we get:
d = 
d =
