y=400+50x

y=300+25x

Step-by-step explanation:

x is the number of minutes and y is the total cost

Answer:

This is because angles inscribed in a semicircles are 90 degrees (BCA)

The tanget of that circle is also a 90 degree angle to the diameter (ABD)

Therefore they're both 90 degrees

The measure of angle BCA must equal the measure of angle ABD should be that angle should be  inscribed in a semicircles that are 90 degrees,

In terms of geometry, an inscribed angle refer to the angle that should be created in the interior of a circle  at the time when two chords should be intersect on the circle. It can also be refer to the angle subtended at a point on the circle via two given points on the circle.

Also, angle should be  inscribed in a semicircles that are 90 degrees,

or, 27000 = L ^ 3

or, cube root undefr 27000 = L

Therefore, Edge length = 30 cm

Answer:

Mean= the average of the number set= 18+18+63+63+84=246/5=49.2

Median- the number in the middle of the set= 63

Mode- the number(s) that repeat=1 8, 63

Range- the amount between the highest and lowest numbers= 84-18=66

Step-by-step explanation:

The mode, mean, and median of the data will be 18 or 63, 49.2, and 63, respectively.

Statistics is the study of collection, analysis, interpretation, and presentation of data or discipline to collect and summarise the data.

The data set is given below.

18, 18, 63, 63, 84

The mode of the data is given as,

Mode = Frequency of the repeated number

Mode = 18 and 63

The mean of the data is given as,

Mean = (Sum of observations) / (Number of observations)

Mean = (18 + 18 + 63 + 63 + 84) / 5

Mean = 246 / 5

Mean = 49.2

The median of the data is given as,

Median = (n + 1)th / 2

Median = (5 + 1)th / 2

Median = 6th / 2

Median = 3th

Median = 63

The mode, mean, and median of the data will be 18 or 63, 49.2, and 63, respectively.

Answer:

x = 36°

Step-by-step explanation:

There are 180° on a line so 180° - 126° = 54°

54° is one of the angles and so is 90° (because it is a right angle)

Therefore, now we know that x = 180° - (54° + 90°)

54° + 90° = 144°

180° - 144° = 36°

x = 36°

Answer:

x = 36

Step-by-step explanation:

solution:

we have given,

            in the right angled triangle.

             exterior angle = [tex]126^{o}[/tex]

we know,

          exterior angle = sum of interior non adjacent angle

   so,   [tex]126^o[/tex] = [tex]x + 90^o[/tex]    [∵ one angle of right angled triangle is [tex]90^o[/tex]]

     or,  [tex]x = 126^o - 90^o\\[/tex]

     or,  [tex]x = 36^o[/tex]

hence, the value of x is [tex]36^o[/tex]
