Answer: D = r*t + r*t <em>372 3/4 = (63 * 2 3/4) + (57 * 3 1/2)</em>
OR
D1 + D2 = Total 173 1/4 + 199 1/2 = 372 3/4
D1 = r1 *t1 63 * 2 3/4 = 173 1/4
D2 = r2 * t2 57 * 3 1/2 = 199 1/2
Step-by-step explanation:
The trip is in two segments, so calculate the distance driven in each portion, then add the two distances together to get the total.
Another way to write the expression would be D = r*t + r*t
Answer:
a=10
Step-by-step explanation:
a^2+b^2=c^2
8 is b
12.8 is c
a^2+64=163.84
a^2=99.84
a=√99.84
a=10
Hope this helps!
