GEOMETRIC PROBABILITY AID?

Mathematics

Find the area of small and large circles:

A_{small}=\pi r_1^2=\pi \cdot (8.01)^2=64.1601,\\  A_{large}=\pi r_2^2=\pi \cdot (4.02)^2=16.1604.

The area of the shaded region is

A_{shaded}=A_{large}-A_{small}=64.1601-16.1604=47.9997.

Use the geometric probability to determine the probability that randomly selected point will be in the shaded region:

Pr=\dfrac{A_{shaded}}{A_{large}} =\dfrac{47.9997}{64.1601} =0.7481.

In percent 0.7481 is 74.81% and rounded to the nearest tenth is 74.8%.

Answer: 74.8%.

Please help me just with 8 and #9.
frosja888 [35]
8) The angles of an octagon are 135 degrees and since they're divided in the middle the angle measures are 67.5.
So 180-67.5-67.5=45 so the measure of the inner degree of each small triangle is 45. There are 3 triangles between points T and P (going clockwise) so its 45(3) is 135 degrees. Your answer is 135 degrees
9) There are 5 triangles between U and I (going counterclockwise) so its 45(5) which is 225

What is the force exerted on an object<br> with a mass of 20 kg and an<br> acceleration of 6 m/s2?
OverLord2011 [107]

Answer:

F = 120 N

Step-by-step explanation:

Given that,

The mass of the object, m = 20 kg

Acceleration of the object, a = 6 m/s²

We need to find the force exerted on an object. The force exerted on an object is given by :

F=ma\\\\F=20\ kg\times 6\ m/s^2\\\\F=120\ N

So, the required force exerted on the object is 120 N.

Randy bought a zero coupon bond and a TIPS 5 years ago for $2,500 each. Both had 10 years to maturity. The TIPS's coupon was 2%
UNO [17]
So, we have that the final value of the zero coupon bond after ten years will be 3000$. The TIPS mature after 10 years, but the interest will be calculated only for 5 years. Each year of interest, the TIPS gains 2%*2500=2*25=50$. Hence the TIPS gains 50$ for each year of interest. Since the interest is not compounding, it will gain 5*50=250$ in value. Hence its total value after ten years is 2500+250=2750$. The total maximum value of the two assets combined is 3000+2750=5750$ and it is attained after 10 years. If one things that money is more important now than in 10 years, the assets could be sold at a lower price; nonetheless their max value never exceeds choice d)=5.750$
