At the neighborhood grocery, 0.5 pounds of salmon cost $3.45. Gianna spent $19.32 on salmon. How many pounds of salmon did she buy, to the nearest hundredth of a pound?

Answer 1

Let x be the number of pounds of salmon Gianna bought.

If 0.5 pounds of salmon cost $3.45, then 1 pound of salmon would cost $3.45 / 0.5 = $6.90.

Therefore, the total cost for x pounds of salmon is $6.90x.

Since Gianna spent $19.32 on salmon, we can set up the equation:

$6.90x = $19.32

Dividing both sides by $6.90, we get:

x = $19.32 / $6.90 = 2.80

Therefore, Gianna bought 2.80 pounds of salmon to the nearest hundredth of a pound.

Answer 2

A satellite flies 79550 miles in 10, point, 7, 510.75 hours. How long would it take to fly 3966439664 miles?

Answer 3

To find out how long it would take the satellite to fly 3966439664 miles, we can set up a proportion comparing the distance traveled to the time it takes.

First, let's determine the speed of the satellite:

Speed = Distance / Time
Speed = 79550 miles / 10.7 hours
Speed ≈ 7430.8411 miles per hour

Now we can set up the proportion:

79550 miles / 10.7 hours = 3966439664 miles / x hours

Solving for x, the time it would take the satellite to fly 3966439664 miles:

x = (3966439664 miles * 10.7 hours) / 79550 miles

x = 5330.70 hours

Therefore, it would take approximately 5330.70 hours for the satellite to fly 3966439664 miles.
