Can someone help me on this

Eva8 [605]

Answer:

100°

Step-by-step explanation:

Angle AKC is a vertical angle with angle BKD, so has the same measure. Since K is the center of the circle, arc AC has the same measure as angle AKC: 100°.

A diagram may help.

A standard piece of paper is 0.05 mm thick. Let's imagine taking a piece of paper and folding the paper in half multiple times.

tatyana61 [14]

Answer:

(a) $g(n)=0.05\cdot 2^n$

(b) $g^{-1}(n)=\log_{2}20g(n)$

Step-by-step explanation:

Part A

The paper's thickness = 0.05mm

When the paper is folded, its width doubles (increases by 100%).

The thickness of the paper grows exponentially and can be modeled by the function:

$g(n)=0.05(1+100\%)^n\\\\g(n)=0.05\cdot 2^n$

Part B

$g(n)=0.05\cdot 2^n\\2^n=\dfrac{g(n)}{0.05}\\ 2^n=20g(n)\\$Changing to logarithm form, we have:\\\log_{2}20g(n)=n\\$Therefore:\\g^{-1}(n)=\log_{2}20g(n)$

Part C

If the thickness of the paper, g(n)=384,472,300,000 mm

Then:

$g^{-1}(n)=\log_{2}20g(n)\\g^{-1}(n)=\log_{2}20\times 384,472,300,000\\=\dfrac{\log 20\times 384,472,300,000}{\log 2} \\g^{-1}(n)=42.8 \approx 43\\n=43$

You must fold the paper 43 times to make the folded paper have a thickness that is the same as the distance from the earth to the moon.

So I am doing geometry in my math class, and I can't figure how how to do some of the problems.We have angles and you have to fi

Marianna [84]

Ok, so in the problem there are 5 angles given but you really only need to focus on <KNL and <MNL. these two angles are a linear pair, or supplementary, which means that they add up to 180˚. so, if <KNL is 38˚, then <MNL is 142˚. 180-38=142

hope this helped

When 240 sixth grade students were polled results showed that 96 students were dissatisfied with the music played at the school

Studentka2010 [4]

Answer: 40%

Step-by-step explanation:

Total students= 240

Dissatisfied students= 96

To get the percentage of sixth grade students that were dissatisfied with the music played in the school, we divide 96 by 240 and multiply the result by 100. This can be written as:

= 96/240 × 100

= 0.4 × 100

= 40%

The percentage represented is 40%
