A=LW  We want to solve for L so divide both sides by W

L=A/W, and we are told that A=120 and W=8 so

L=120/8 m

L=15m

(now if that isn't a typo and you actually want the length in cm then)

L=15m(100cm/m)=1500cm

Suppose you throw a dart at a circular target of radius 10 inches. Assuming that you hit the target and that the coordinates of
sukhopar [10]

Answer:

a) The probability is 0.04

b) The probability is 0.36

c) The pprobability is 0,25

d) The probability is 0.09

Step-by-step explanation:

Lets calculate areas:

the target has a radius of 10 inces, hence the target area has a area on 10²*π = 100π square inches.

a) A circle of 2 inches of radius has an area of 2²π = 4π square inches, hence the probability of hitting that area is 4π/100π = 1/25 = 0.04

b) If the dart s within 2 inches of the rim, then it is not at distance 8 inches from the center (that is the complementary event). The probability for the dart to be at 8 inches of the center is 8²π/100π = 64/100 = 16/25 = 0.64, thus, the probability that the dart is at distance 2 or less from the rim is 1-0.64 = 0.36.

c) The first quadrant has an area exactly 4 times smaller than the area of the target (each quadrant has equal area), thus the probability for the dart to fall there is 1/4 = 0.25

d) If the dart is within 2 inches from the rim (which has probability 0.36 as we previously computed), then it will be equally likely for the dart to be in either of the 4 quadrants (the area that is within 2 inches from the rim forms a ring and it has equal area restricted on each quadrant). Therefore, the probability for the dice to be in the first qudrant and within 2 inches from the rim is 0.36*1/4 = 0.09.

What’s the answer for IJG
Flauer [41]

Answer:

<u>∠IJG = 123° </u>

Step-by-step explanation:

Since AB║CD, EF ║GH, we can use the Corresponding Angles Postulate, for finding the following congruent angles:

∠IKL ≅ ∠EIJ and  ∠EIJ  ≅ ∠GJA

∠GJA and ∠IJG are supplementary, therefore:

∠GJA + ∠IJG = 180°

∠IJG = 180° - 57°

<u>∠IJG = 123°</u>
