1.7 x 10 ^-23
Or maybe 1.6 x 10^-23
(The -23 is how many 0’s there are).
Against the wind:
distance = 3400 km
time = 5 hr.
rate = d/t = 3400/5 = 680 km/hr
With the wind:
distance = 3400 km
time = 4 hr
rate = d/t = 3400/4 = 850 km/hr
Equations:
plane speed - wind speed = 680 km/hr
plane speed + wind speed = 850 km/hr
2(plane speed) = 1530
plane speed = 765 km/hr
Substitute and solve for "wind speed":
765 + wind speed = 850
wind speed = 85 km/hr

If Martina becomes the manager she will make $10.40 hourly.
Equation: $8÷30%= x $x+ $8= $10.40
To calculate The number of tissues package each day, you would take the number of tissues a box holds multiplied by how many boxes the manufacturing plant packages each day. We don't know the number of boxes, so that is where we would use a variable. I would use b.
250b would be an algebraic expression representing this.
180 - 83 = 97 I Hope this Helps <3
