Answer:
weight of 25 students
25 × 58 = 1450kg
weight of 29 students
29 × 62 = 1798kg
total students = 25 + 29 = 54
total weight of students = 1450 + 1798 = 3248
mean weight of all students = 3248/54 = 60.19kg
Answer:
8 2/3 divided by 4 1/8=2 1/10 is Correct
exactly 2 10/99
A. 69 degrees
exterior angles should equal 360 degrees so just add 131+160= 291 , 360-291= 69 degrees
or u can find it by finding the interior angle degrees by using supplementary angles. 180-131= 49 , 180-160= 20, 20+49=69, 180-69= 111 so the missing exterior angle corresponding interior is 111 and u can use supplementary angles to find the exterior. 180-111= 69 degrees
Answer:
a, the number of pupils that like maths
b. we are given the number of students in the class and the percentage that like maths
c. percentage of students that like maths x total number of students
0.7 x 40
d. 0.7 x 40
28
Step-by-step explanation:
Number of pupils that like maths = percentage of students that like maths x total number of pupils in the class
(70 / 100) x 40 = 28 pupils
Answer:
(25,-26)
Step-by-step explanation:
difference between the two points in x and y coordinates are
x = 10 - (-5) =15, y = -9 - 8 = -17,
so to get to the other endpoint you need to add another
x = 15 and y = -17 to the midpoint, (10,-9).
10+15 = 25 for x and -9 - 17 is -26 for y.
