Use the formulla d=rt.find t for r =48.3m/h and d=545.79m.

1 answer:

4 0

If you solve d = rt for t, you have t = d/r. If we have values for d and r we will fill them into that equation and divide. $\frac{545.79m}{48.3 \frac{m}{h} }$ . Setting that up so the meters cancel as they should looks like this: $545.79m* \frac{h}{48.3m}$ lets us divide as we need to and at the same time cancel out the distance, leaving us time in hours. The t value then is 11.3 hours.

A sack of potatoes weighs 14 pounds 9 ounces after wendy makes potato salad for a picnic the sack weights 9 pounds 14 ounces wha

dlinn [17]

For this case we have the following conversion:
1 pound = 16 ounces
Then we rewrite the sack weights:
14 pounds 9 ounces = 14 9/16
9 pounds 14 ounces = 9 14/16 = 9 7/8
Then, we subtract both values:
(14 9/16) - (9 7/8) = 4.6875 = 4 + 0.6875
Rewriting:
4 + 0.6875 = 4 + 6875/1000
4 + 1375/200 = 4 + 275/40
4 + 275/40 = 4 + 55/8
Answer:
the weight of the potatoes wendy use for the potato salad is:
4 + 55/8 pounds
