If y varies inversely as x, and y=9 when x =10, find y when x=5

The value of x is given by 13.

The above angle of the triangle is vertically opposite to the angle 110.

So, the above not mentioned angle of triangle is = 110.

We know from Angle sum property of a triangle that the sum of all interior angles of a triangle is 180.

So, from the given figure we can write that,

110 + 57 + x = 180

167 + x = 180

x = 180-167

x = 13

Hence the value is, x=13.

Answer:

240

Step-by-step explanation:

20%×5=100

48×5=240

Answer:

20% of 240 is 48.

Step-by-step explanation:

Forming the equation,

→ (x/100) × 20 = 48

Now the value of x will be,

→ (x/100) × 20 = 48

→ (20x/100) = 48

→ x/5 = 48

→ x = 48 × 5

→ [ x = 240 ]

Hence, the answer is 240.

4.2 x 10^8 is  2*10^6  times the value of 2.1 x 10^2 when division is performed.

The concept that will be used to solve the question is division operation.

We were given 4.2 x 10^8 which is greater than  2.1 x 10^2

The operation can be expressed as :

4.2 x 10^8 =( n *2.1 x 10^2)

where n = the number of times that 4.2 x 10^8  is greater than 2.1 x 10^2

Then make n the subject of the formular which is

n = 4.2 x 10^8/2.1 x 10^2

n = 2*10^6

Therefore, the values of 4.2 x 10^8 is greater than 2.1 x 10^2 in 2*10^6 times.

The value of x is 33

What other external angles are there?

The alternate exterior angle theorem states that when two parallel lines cross, the exterior angles formed on either side of the transversal are equal. The distance between two intersecting lines or surfaces at or around their meeting point is referred to as the angle.

Since (2x - 30°) and (x+3)° are alternate exterior angles, they will be equivalent to one another.

(2x - 30)° = (x+3)°
Separate all similar phrases, then determine the value of x:
(2x - 30)° = (x+3)°
2x - x = 33 + 3
x = 33
Consequently, x will have the value of 33.

Answer

500 tickets were sold

Step-by-step explanation:

Since 100 main floor tickets were sold, and each cost $7.50, we multiply it by 100 which equals $750, then since revenue was $3250, we do $3250 - $750 = $2500. Now that we got the extra tickets taken out of the way, time to find the rest. First, we add the prices of both tickets together, $7.50 + $5 = $12.50, then divide it by the remaining revenue, $2500 divided by $12.50 = 200 tickets, so 200 of each ticket were sold, + 100 main floor tickets. So now we do 300 main floor tickets + 200 balcony tickets, which is 500 tickets in total. Maybe you didn't read this but that's alright :)

Step-by-step explanation:

A two sigma confidence interval is created whenever our alternate hypothesis does not equal a value.

For example if

[tex]h_{o} = 0.36[/tex]

and

[tex]h _{a} ≠0.36[/tex]

We used a two sigma confidence interval because we are thinking a portion is either below 0.36 or above 0.36.

When solving these probability for the p value, multiply the inital result by 2 to get the p value

The 2 sigma confidence interval is a principle that states that a result will be considered significant if 95% of the population is two standards deviation from the average value.

The two-sigma confidence level states that 95% of the values obtained in the results from a population should be within2 deviations from the mean. Anything below this acceptable percentage is not considered the 2-sigma confidence level.

If 68% of the score are within 1 standard deviation from the mean, then that will be considered the 1-sigma rule. If 99.7% of the score is 3 standard deviations from the mean then we can refer to that as the 3-sigma confidence interval.

The ∠ACD is a straight angles

We know the angles on a straight line add up to 180 degree

Therefore,

The measure of angle ACD = 180 degrees

Here it is given that the line FC bisects angle ACD

Therefore, The angle ACF is equal to Angel DCF

Angle ACF = Angel DCF

Angle ACF + Angle DCF = 180 degrees
