So basically the ladder is creating a right triangle with the ground and the wall. Ladder is the hypotenuse (h), building = b, ground = g
b = h - 22 ft
g = 1010 ft
use Pythagorean Theorem to determine the length of h:
The h^2 terms cancel out to = 0
The answer is 48 because you multiply all the numbers.
Part A:
Given that <span>A
presidential candidate plans to begin her campaign by visiting the
capitals in 4 of 50 states.
The number of ways of selecting the route of 4 specific capitals is given by
Therefore, the probability that she selects
the route of four specific capitals is
Part B:
</span>
<span>The number of ways of selecting the route of 4 specific capitals is 5,527,200.
Since </span><span>the number of ways of selecting the route of 4 specific capitals is too large it is not practical to list all of
the different possible routes in order to select the one that is best.
Therefore, "</span><span>No, it is not practical to list all of the different possible
routes because the number of possible permutations is very
large."</span>
The correct answer is 0.99kg/L
Explanation:
To find the density, the first step is to convert the weight (mass) and the volume into the appropriate units.
The volume is 8.5 gallons and this needs to be converted to litters. In this case, multiply the volume in gallons by 3.785 because each gallon contains 3.785 liters.
8.5 x 3.785 = 32.1725 liters
The mass is 70 pounds and this needs to be converted to kilos. In this case, divide the pounds by 2.204 considering each kilo contains 2.204 pounds.
70 ÷ 2.2046 = 31.751 kilos
Now, find the density by dividing the mass into the volume.
Density= 31.751 kg ÷ 32.1725 L
Density = 0.98 kg/L
This means the density is 0.9.868 kg/L and this can be rounded as 0.99 kg/L
