20 miles per hour
If it can cover 40 mph in 2 hours divide 40 by 2 to get the amount for one hour and 40/2=20mph

Cosine = Adjacent / Hypotenuse
∆ABC, where lets say B is the right angle.
cos C = adjacent/hypotenuse = BC/AC

slope = 3
y-intercept = 1
explanation
slope, m = (y2-y1)/(x2-x1)
= (19-10)/(6-3)
= 9/3
= 3
equation of a line is y = mx + c
at point (3,10)
=> 10 = 3*3 + c
=> c = 10-9
=> c = 1
finding y-intercept when x = 0
y = mx + c
by putting the values we have
y = 3*0 + 1
y = 1

Answer:
b=3in
Step-by-step explanation:
SO first of all, the formula for area is lxw (length x width)
And our question tells us that
l x w=24in^2
4 x w = 24 (question tells us that length is 4 inches as listed on side)
4 x (b+3) = 24 (b+3 is the total width of the postcard)
4b + 12 =24 (multiply by 4 inside the bracket)
4b=12 (subtract 12 from both sides)
b=3 (solve for b by dividing by 4)
X = 88.2
