We are given the speed of the shuttle as:
speed = 28,000 miles / hour
We know that:
1 mile = 5280 ft
24 hour = 1 day
Therefore by conversion:
speed = (28,000 miles / hr) * (5280 ft / 1 mile) * (24 hr
/ day)
speed = 3,548,160,000 ft / day
In 2 significant figures:
<span>speed = 3.5 x 10^9 ft / day</span>
Answer:
Step-by-step explanation:
we know that
The area of the decking is equal to the area of the parallelogram minus the area of the pool minus the area of the sand box
Remember that
so
6 - 2x = 18
-2x = 12
x = -6
90 grams are equivalent to 0.09 kilograms and 55 grams are equivalent to 0.055.
So 0.09 + 0.055 = 0.145.
0.145 * 12 = 1.74
So 1.74 kilograms of sugar is needed to make 12 crisps.
