A. X = -6; X = 4
B. X = -1; x = 4
C. x=-1; x = 3
D. X = 5; x = -4

Answer:

Step-by-step explanation:

By triangle sum theorem,

73°+ 39° + m∠1 = 180°

m∠1 = 180° - 102°

m∠1 = 78°

Since, m∠1 = m∠2 [Vertically opposite angles]

m∠2 = 78°

Sum of interior angles of a polygon = (n - 2)×180°

Where n = number of sides of the polygon

Sum of the interior angles of a quadrilateral = (4 - 2)×180°

= 360°

Therefore, 77° + m∠3 + 90° + m∠2 = 360°

77° + m∠3 + 90° + 78° = 360°

m∠3 = 360° - 245°

m∠3 = 115°

Given that :

Fraction of pocket money spent by Jamal = 3/4

The number line is divided into 4 equal parts with distance between successive tick marks representing 1 of the whole = (1/4). Hence, 3/4 of the whole would mean 3 portions of the total 4 portions of the number line represents the amount spent by Jamal.

The fraction spent by Jamal is also labeled on the number line picture in the attached document.

Answer:

135°

Step-by-step explanation:

here's your solution

=> we know that , sum of all angles is

equal to 180°

=> hence ,we have two angles

=> 1st angle = 45°

=> 2nd angle = 9x + 18

=>. adding both angle

=> 45° + 9x + 18° = 180°

=> 63° + 9x = 180°

=> 9x = 180° - 63

=> 9x = 117°

=>. x = 117/9

=> x = 13°

=>. hence, the required angle = (13*7) + 18°

=> angle = 135°

17+21+15+15+25+x=150

93+x=150

x=150-93

x=57

Answer:

age=57

Step-by-step explanation:

ages=17 21 15 15 25 ?

17+21+15+15+25=93(old mean)

17+21+15+15+25+?=25(new mean)

25(new mean)*6(number of numbers)=150

?=150-93=57

= 57

The common prime factor of the numbers  77 and 242? will be 11.

A number can be expressed as the product of its prime factors through the process of prime factorization. A number with exactly two factors, 1 and the number itself, is said to be a prime number. As an illustration, let's use the number 30. Even though we are aware that 30 = 5 6 is not a prime number,

Given that the numbers are 77 and 242. The prime factor of the numbers is calculated as,

77 / 11 = 7

242 / 11 = 22

Hence, the number 11 is completely dividing both the numbers 77 and 242 so the prime factor of the numbers is 11.

Answer:

Yes

Step-by-step explanation:

Being proportional means that if you divide the Y value by the X number for each ordered pair, they all equal the same number

For this case, this is proportional because you need to multiply by 6 to get the Y value.

Answer:

1. r = 5 m 2. a = 25.6 m/s²

Step-by-step explanation:

The relation between the velocity, the radius of path and the acceleration on the circular path is given by :

[tex]a=\dfrac{v^2}{r}[/tex]

1. Acceleration, a = 39.2 m/s²

Velocity of the car, v = 14 m/s

The radius of the path can be calculated using the above formula i.e.

[tex]r=\dfrac{v^2}{a}\\\\r=\dfrac{(14)^2}{39.2}\\\\r=5\ m[/tex]

2. Velocity of the car, v = 8 m/s

The radius of the path, r = 2.5 m

The acceleration of the car is given by :

[tex]a=\dfrac{8^2}{2.5}\\\\a=25.6\ m/s^2[/tex]

Hence, this is the required solution.
