Answer:
speed = (125×1000/2×60×60) m/s
=125000/7200 m/s
=17.36 m/s
1 pound of rice costs $3.45
1.2 pounds of rice costs x
Set up the proportion
1 / 1.2 = 3.45 / x Cross Multiply
x = 1.2 * 3.45 Combine
x = $4.14 Answer
C. 6.2g can be combined with -3/8y. This is because they both end in ‘y’.
1 because 10/9= 1 1/10
which is closer to 1
X= -5/2 (0.4)
or
x= -2 1/2 (2.5)
