740 square meters
Just find the areas of all the faces of the prism. And add then all up:
Area of rectangular base (bottom):
16 • 10= 160 square meters
Area of triangle facing front:
1/2 • 15 • 16= 120
Multiply 120 by 2 cause theres a same triangle facing back the prism: 120 • 2= 240
Area of rectangle facing right:
10 • 17= 170
Multiply 170 by 2 cause theres a same rectangle facing left the prism: 170 • 2= 340
Add them all up together:
160+ 240+340= 740
Comm.ent me if u have any questions
MARK ME BRAINLIEST TYSM! Say if my answer was wrong/right!
Answer:
x= -3/4
Step-by-step explanation:
Combine like terms
21x+17=x+2
-17. -17
21x= x-15
-x -x
20x= -15
Divide
x= -0.75 or -3/4
Answer:
discrete, the class boundaries are;
16 - 25
26 - 35
36 - 45
46 - 55
56 - 65
66 = 75
continuous, the class boundaries are;
16 to less than 26
26 to less than 36
36 to less than 46
46 to less than 56
56 to less than 66
66 to less than 76
Step-by-step explanation:
Given that;
Range of the dataset = maximum value - minimum value = 74 - 16 = 58
total number of data set n = 50
Rule : ≥ n
substitute value of n
≥ 50
k × log(2) = log( 50 )
k × 0.3010 = 1.69897
k = 1.69897 / 0.3010
k = 5.64
Hence, we have a total of 6 number of classes needed to be constructed.
so,
class width = 74 - 16 / 6 = 58 / 6 = 9.67
If the Data is discrete, the class boundaries are;
16 - 25
26 - 35
36 - 45
46 - 55
56 - 65
66 = 75
If the Data is continuous, the class boundaries are;
16 to less than 26
26 to less than 36
36 to less than 46
46 to less than 56
56 to less than 66
66 to less than 76
Angle EJM (69°) and Angle KJL(69°) will EACH equal one half of the intercepted arcs.
So, 69° = .5 * (arc EM + arc KL)
69° = .5 * (58° + arc KL)
69° = 29 + .5 *arc KL
40° = .5 * arc KL
Therefore arc KL = 80°
