Answer:

mAC = 40

Step-by-step explanation:

Use similar triangles,

BAC and DAB are similar

therefore

CA/AB = BA/AD

CA/20 = 20/10

cross multiply

AC = CA = 20*20/10 = 40

Or use metric relations

CA*AD = BA^2

CA = BA^2/AD = 20^2/10 = 40

Answer:

565.7 cubic units

Step-by-step explanation:

Volume of cylinder=2πrh

                               =2x(22/7)(10)(9)

                               =180x(22/7)

                               =565.7

Answer:

x =55 degrees

y = 35 degrees

Step-by-step explanation:

We know that the distance from the center of the circle to the circumference is the radius

that means the triangle starting out from O is isosceles since two of the sides are radii and thus the angle of those sides are the same

Let us call one of the angles z

we know that the sum of the angles in a triangle is 180 degrees

That simply means;

80 + 2z = 180

2z = 180-80

2z = 100

z = 100/2

z = 50 degrees

So the angles at each upper end of the cyclic quadrilateral are;

x + 50 and y + 50

we know that the angles that face each other in a cyclic quadrilateral are supplementary

Thus;

95 + y+ 50 = 180

y= 180-95-50

y= 180-145

y = 35 degrees

Now, for x, the angle supplementary to the angle that faces x+ 50 equals x + 50

Thus;

x + 50 = 105

x= 105-50

x = 55 degrees

Answer:

73,205 vinyls

Step-by-step explanation:

To calculate the number of vinyls sold we need to calculate the compounded increase. To do this we simply raise the number of times that the initial value increases by the number of difference in years from the start to the current year. Then we multiply this number by the initial number of vinyl records. Since there are 4 years between 2012 and 2016, the formula would be the following...

50,000 * [tex]1.1^{4}[/tex] = x

50,000 * 1.4641 = x

73,205 = x

Finally, we can see that there will be a total of 73,205 vinyls in 2016

Answer:

Scott always has 2 more fish per hour or S=M+2

Step-by-step explanation:

5-3 = 2, 9-7 = 2,...

For any given hour, Scott has reeled in 2 more fish compared to Megan.

We can see this by subtracting Scott's amount and Megan's amount for any row.

Because any given row has the same difference, this tells us that the slopes of each are the same.

The equation for Megan is y = 4x-1 while Scott's equation is y = 4x+1

x = number of hours, y = number of fish caught

Lines with equal slopes indicate parallel lines. If these trends keep up, then Megan will never catch Scott (she'll always be 2 fish behind him).

Step-by-step explanation:

25 is missing in the last step.

Option C is the correct answer.

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

To complete the square, we add and subtract the square of half of the coefficient of x, i.e., (10/2)² = 25, inside the parentheses:

8(x²+ 10x + 25 - 25) = -5

Simplifying the expression inside the parentheses.

8(x + 5)² = 200

Dividing both sides by 8.

(x + 5)² = 25

Taking the square root of both sides.

x + 5 = ±5

Solving for x.

x = -10 or x = 0

Thus,

The missing number is 25.

Probability of 100 managers being selected= 100C100*1100C800/1200C900

Probability of selecting just one manager = 1C100*1199C899/1200C900

Explanation:

Given 100 managers, 200 factory workers, 900 miscellaneous workers, and workers bring transferred 900

To find probability of 100 managers leaving given that probability = number of favorable outcomes/total number of outcomes

We use combination since order doesn't matter:

Combination formula= n!/r!(n-r)! Where n= total number of outcomes and r is number of outcome at one time and ! is factorial

Probability of 100 managers using nCr formula for each item = 100C100*1100C800/1200C900

Probability of 1 manager also applying nCr formula as above =1C100*1199C899/1200C900

The probability is the ratio of the favorable event to the total number of events. The probabilities are as follows;

a.  P = ¹⁰⁰C₁₀₀ × ¹¹⁰⁰C₈₀₀ / ¹²⁰⁰C₉₀₀

b.  P = ¹⁰⁰C₁ × ¹¹⁹⁹C₈₉₉ / ¹²⁰⁰C₉₀₀

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen.

Your company is considering offering 600 employees the opportunity to transfer to its new headquarters in Ottawa and, as personnel manager, you decide that it would be fairest if the transfer offers are decided by means of a lottery.

Assuming that your company currently employs 100 managers, 300 factory workers, and 900 miscellaneous staff.

We can use combination since order does not matter;

a)  The probability of all the managers will be offered the opportunity will be

[tex]P = \dfrac{^{100}C_{100} * ^{1100}C_{800}}{^{1200}C_{900}}\\[/tex]

b)  The probability of you will be offered the opportunity will be

[tex]P = \dfrac{^{100}C_{1} * ^{1199}C_{899}}{^{1200}C_{900}}\\[/tex]

Step-by-step explanation:

Start by using the distance formula to find the raidus

The two points are (-2,1) and (-4,1)

√((-4+2)²+(1-1)²)= 2

The radius is two and we have our center which means we can write

(x+2)²+(y-1)²=4

now it's just a matter of expanding everyhting

x²+4x+4+y²-2y-3=0

x²+y²+4x-2y+1=0

7 7/8 is my answer

Step-by-step explanation:

All you need to do is turn you mixed numbers into improper fractions 4 1/2 as an improper fraction is 9/2 and 1 3/4 as an improper fraction is 7/4. Then, you would mulitply them which will give you 63/8. After that, you would divide 63 by 8 which is 7 is you is your answer but you also have 7 as a remainder, which is good. That would be your numerator and the other 7 would be your mixed number. The 8 we were just talking about, would stay as your numerator. So, your answer is 7 7/8.  

Hope that helps!!
