Alright!
The formula of area of a triangle is base x height /2
so you're given the height and hypotenuse.
Do the reverse of the pythagorean theorem to find the base
a^2= c^2 -b^2
c^2 is the hypotenuse and b^2 is the height
a^2= 10^2 - 8^2
a^2 = 100 - 84
a^2 = 16
a= (square root the 16)
a= 4 cm
now put these numbers into the formula for area of a triangle
bxh / 2
(4x8)/ 2
= 16 cm squared !!
hope that makes sense :)
- Start position: -2
- East 4 units
- West 5 units
- East 6 units
- West 7 units
(-2) + (4) + (-5) + (6) + (-7) = -4
Total distance traveled: (Start position)-(End position) = (-2)-(-4) = 2
The ant travels a total of 2 units from its starting position. But traveled 22 units overall.

Answer:
40 Laps per Hour
Step-by-step explanation:
45 * 5 * 12 = 2700
2700/60 = 45
1800/45 = 40
Answer:
0.1979 or 19.79%
Step-by-step explanation:
If 20% of all bulbs are defective, there is a 20% chance of each bulb being defective and an 80% chance of each bulb not being defective.
This is a binomial probability model with probability of success (bulb being defective) of p=0.20.
In order for the lot to pass inspection, it must contain either zero or one defective bulb, the probability of one of these scenarios occurring is:
The probability that the lot will pass inspection is 0.1979 or 19.79%.
