Answer:
326.666miles
Step-by-step explanation:
v=distance/time (v=d/t)
d=140 miles
t=3hrs
v=d/t, v=140/3, v= 46.666mph
v=46.666mph
t=7hrs
d=?
v=d/t, d=vt, d=46.666mph x 7hrs, d= 326.666miles
Answer:
B. m, (3m +1), and (m +2)
Step-by-step explanation:
The product of the constants in the binomials must be +2 in order for those binomials to be factors of the volume expression. That is only the case for ...
B. m, (3m +1), and (m +2)
Answer:
a, c
Step-by-step explanation:
3.2(4p + 8.5)
= 12.8p + 27.20 (C)

Set an equation:
4/5=x-3/x+1
cross multiply
5x-15=4x+4
x=19
Width: 16 cm
Length: 20 cm
Find the perimeter and the area:
Perimeter: 16+16+20+20=72
Area: 20•16=320
Ratio: 320:72
Simplify the ratio:
40:9
Answer: The ratio of the area to the perimeter is 40:9.
