The sum of the measures of the interior angles of a polygon of n sides is
180(n - 2)
If the polygon is regular, all angles are congruent, and each angle measures
[180(n - 2)]/n
Set the measure of one angle equal to 140, and solve for n, the number of sides.
[180(n - 2)]/n = 140
180(n - 2) = 140n
180n - 360 = 140n
40n = 360
n = 9
The number of sides is 9.
We are given: Barrel quantity averages = 50 pounds.
Crate quantity = 120 pounds.
Number of barrels is taken by variable x and
Number of crates is taken by variable y.
The elevator load should be greater than of total load.
Therefore,
50 * number of barrels + 120 * number of crates > Total load.
50*x +120*y > Total load.
50x +120y > total load.
Power = Current *Voltage
You already have the current, but not the voltage.
But you are given resistance, and you know that
Voltage=Current*Resistance
Therefore
V=I*R=4*12=48V
So you have 48V
Now you can figure out the Power
P=I*V=4*48=192W
Therefore you have 192W.
hope this helps
Answer:
170.097 grams are in 6 ounces
Answer:
1.575 × 10^6 gallons
Step-by-step explanation:
1.25 × 10^6 = 1.25 × 1,000,000 = 1,250,000 gals.
Dolphin tank = 325,000 gals.
total vol. = 1,250,000 + 325,000 = 1,575,000 gals.
scientific notation = 1.575 × 10^6 gallons
