Answer: 10 cm


Step-by-step explanation:

The circumference of the CD = 22\pi


We know that the formula of the circumference is:


Circumference = 2\pi r


We will substitute the value of circumference to find the radius:


22 pi = 2 x pi x r


r = 11


Therefore its radius will be 22 / 2 = 11 cm


Jamie wants to cut the CD from the middle of the CD to one side but leaving one cm. To find the measurement of the cut portion, we will subtract 1 from 11 to get:


11 - 1 = 10 cm

Find the percent of change from the first value to the second. 72: 81 -
nordsb [41]

Answer:

+12.5%

Step-by-step explanation:

This is rather simple. Subtract 72 from 81, then put the difference over 72. Then, multiply that by 100.

(81 - 72)/72 * 100

<em>Subtract 72 from 81 to get 9</em>

9/72 * 100

<em>Multiply 9 by 100 to get 900</em>

900/72

<em>Simplify the above fraction by cancelling out 9.</em>

100/8

<em>Divide 100 by 8 to get 12.5%</em>

The percent of change is +12.5%

What is 20.00 multiplied by 20.00
Gala2k [10]

Answer:

400.00

Step-by-step explanation:

20*20 is close to 2*2. Since we have zeros, we can multiply 2 and 2 to get 4. Then we add two zeros because of the zero in 20 and the zero in the other 20. This could also be written as 20^{2} because we're multiplying 20 by itself.

Sergio [31]

function rule describes the amount of profit that will be made by the student council on the shirt sales is  7.5x-45 .

<u>Step-by-step explanation:</u>

Here we have , student council at Smith Valley High School is planning to sell t-shirts as part of a fundraiser using company A, the shirts cost $4.50 each. The student council has to pay the shirt company a design fee of $45. the shirts will be sold for $12 each. We need to find a function rule describes the amount of profit that will be made by the student council on the shirt sales . Let's find out:

Each shirt cost $4.50 . The student council has to pay the shirt company a design fee of $45. the shirts will be sold for $12 each , So the total amount of t shirt he sell is :

⇒  12x , where x is the number of t shirts !

Now , expenses is given by :

⇒  45+4.5x , where x is the number of t shirts !

So , Profit made is :

⇒  12x-(45+4.5x)

⇒  7.5x-45

Therefore , function rule describes the amount of profit that will be made by the student council on the shirt sales is  7.5x-45 .

Two weather stations are aware of a thunderstorm located at point C. The weather stations A and B are 27 miles apart. How far is
cluponka [151]

Station A is at a distance of 28.83 miles from the storm

<h3>Sine rule</h3>

Sine rule is used to show the relationship between the sides of a triangle as well as their opposite angles. It is given by:

\frac{a}{sin(A)}= \frac{b}{sin(B)}=\frac{c}{sin(C)}

From the diagram:

  • A = 34° + 90° = 124°

Also:

  • B = 90° - 61° = 29°

Hence:

  • C + A + B = 180°
  • C + 29 + 124 = 180
  • C = 27°

b = distance station A from the storm, c = AB = 27 miles

Using sine rule:

\frac{c}{sin(C)} =\frac{b}{sin(B)} \\\\\frac{27}{sin(27)}=\frac{b}{sin(29)}  \\\\b=28.83\ miles \\

Station A is at a distance of 28.83 miles from the storm
