Volume of a sphere formula: V=4/3*pi*r^3
Surface Area of a Sphere formula: SA=4*pi*r^2
SA=14,657,414 
V=5,276,669,286
ratio= SA;1 : V;360

grandymaker [24]

Answer:

The right option is B) 12.60

Step-by-step explanation:

We have given,

Number of shares = 30

Cost of each share = $34

Total cost of shares = 30 × 34 = $1020

Since the company paid annual dividends of $0.42 per share.

i.e Total annual dividend company paid = 0.42 × 30

Total annual dividend company paid = $ 12.60

Hence the right option is B) 12.60

Who can do this question, I don't know how to do...this is difficult for me....who can teach me?
cupoosta [38]
We know that AB and CD are parallel.  This allows many assumptions.
From that we know that angle A and angle D are congruent. 
That means that x + 8 = 2x - 22 and we can solve for x
x + 8 = 2x - 22
x + 30 = 2x
30 = x or x = 30

We know from the figure that angle B is x or now that we solved for x is 30 degrees.  Also, we know that both angle A and angle D are 38 degrees.  Now we can solve for the vertical angle E which has a measure of y degrees.  A triangle has the sum of its angles equal to 180 degrees.

We can set up an equation like this 30 + 38 + y = 180
30 + 38 + y = 180
68 + y = 180
y = 112 degrees

That is how you would solve this problem

Find the range of the given data set. 5/8, 3/4, 1 1/8, 1 1/4 A)5/8 B)3/4 C)1 1/8
rodikova [14]

Answer:

A)5/8

Step-by-step explanation:

  • <em>The range of a set of data is the difference between the highest and lowest values in the set. </em>

<u>Given data set:</u>

  • 5/8, 3/4, 1 1/8, 1 1/4

<u>Rewriting the data set in the same denominator to compare:</u>

  • 5/8, 6/8, 9/8, 10/8

<u>As we see the smallest value is 5/8 and the highest value is 10/8, so the difference:</u>

  • 10/8 - 5/8 = 5/8

So, the range of the given data set is 5/8

<u>Correct choice is</u>: A)5/8
