Answer:
40 in.^2
Step-by-step explanation:
Let's name the 2 shaded triangles: The left one is T1 and the right one is T2.
The area of a right triangle can be found using the equation (a*b)/2.
The 2 legs of T1 are 8 in. and 6 in. (from 10 - 4)
Area of T1 = = 24 in.^2
The 2 legs of T2 are 8 in. and 4 in.
Area of T2 = = 16 in.^2
Area of shaded region = 16 + 24 = 40 in.^2
Hi again Lacy!
The answer would be 45.3. The same steps I took with the last question applies here, just this time in the TENTHS instead of HUNDREDTHS (I almost didn't catch that myself until I reread the problem and Kmc's post xP)
45.3297 -> 45.330 -> 45.33 -> 45.3
B it is similar but not congurent
(6.5 + p)/3
or
1/3(6.5 + p)
same answer written a different way
Answer:
A=368 miles
B= 356.3 miles
Step-by-step explanation:
Given data
Let the two trains be A and B
A+B=724.3----------1
A-B=11.7--------------2
From eqn 1
A= 724.3-B
put this in place of A in eqn 2
724.3-B-B= 11.7
724.3-2B= 11.7
724.3-11.7= 2B
712.6=2B
B= 712.6/2
B= 356.3 miles
Put B=356.3 in eqn 1
A+356.3=724.3----------1
A= 724.3-356.3
A=368 miles
