The answer is D. This is because when you take 10.65 and subtract 9.95 from it you get 0.07. If you take this number and continuously add to 9.95 you get the numbers provided in the chart. We'll also notice that the 0.07 is only added after 10 minutes of talking (10,20,30,etc.).

Answer:

Step-by-step explanation:

21)

The sine rule is expressed as

a/SinA = b/SinB = c/SinC

Where a, b and c are the length of each side of the triangle and angle A, Angle B and angle C are the corresponding angles of the triangle. Therefore,

12/Sin 64 = x/Sin 12

Cross multiplying, it becomes

xSin 64 = 12Sin12

xSin 64 = 12 × 0.209

0.8988x = 2.508

x = 2.508/0.8988

x = 2.79

The sum of the angles in a triangle is 180 degrees. Therefore, the unknown angle in triangle is

180 - (64 + 12) = 104 degrees. Therefore,

y/Sin104 = 12/Sin64

ySin64 = 12Sin104

0.8988y = 12 × 0.9703 = 11.6436

y = 11.6436/0.8988

y = 12.95

22) we would apply the law of Cosines which is expressed as

a² = b² + c² - 2bcCosA

Therefore,

28² = 20² + 24² - 2 × 20 × 24Cosx

784 = 400 + 576 - 960Cosx

784 = 976 - 960Cosx

960Cosx = 976 - 784 = 192

Cosx = 192/960 = 0.2

x = Cos^(-1)0.2

x = 78.5°

borishaifa [10]
To find the approximately volume you will use the formula for finding the volume of a cylinder:

V = pi x r^2 x h
      3.14 x 0.5^2 x 21
V = 16.485

The volume is approximately 16.49 cubic inches.

Llana [10]

For Marvin used the Quantitative Reasoning Process to build a budget while he is going to college. He worked hard over the summer and saved $2,595.9 to live on during the next two semesters of school. Marvin will receive a scholarship each semester for $958.35 money can Marvin spend each month, on average, for things like groceries, entertainment, and miscellaneous items is mathematically given as  

$4512.6

<h3>How much money can Marvin spend each month, on average, for things like groceries, entertainment, and miscellaneous items?</h3>

Savings with Marvin = $2,595.9

Scholarship amount  = $958.35

Total Scholarship amount received in 2 semesters = $958.35 X 2 = $ 1916.7

Now total money that Paolo have = (Savings with Marvin) + (Total Scholarship amount received in both semesters) = $2,595.9 + $1916.7 = $ 4512.6

Tuition & books cost  = $2000

Tuition & books cost for 2 semesters = $2000 X 2 = $4000

Housing cost for 2 semester contract =$1,000

Total expenses in books and housing = $4000+ $1000 = $5000

Money left with Marvin after Total expenses in books and housing = $ 4512.6 - $5000 = −487.4

This means he has overspent.

as no. of months in 2 semesters = 8

Amount that Marvin would be in debt each month = −487.4/8 = −$60.925
