consecutive integers have a difference of 1 between them
let the brothers have ages n , n + 1 and n + 2 thus
n + n + 1 + n + 2 = 96
3n + 3 = 96
subtract 3 from both sides of the equation
3n = 96 - 3 = 93
divide both sides by 3
n = 
= 31
The ages are 31 , 32 and 33
Answer:
240 cm², A = 300 cm², and 540 cm²
Step-by-step explanation:
1) The area of a parallelogram is A = bh, so:
A = (20)(12)
A = 240 cm²
2) Similarly, the area of a rectangle is A = bh, so:
A = (15)(20)
A = 300 cm²
3) The composite area is the sum of both the rectangle's area and the parallelogram's area, so:
240 cm² + A = 300 cm² = 540 cm²
Answer:
Step-by-step explanation:
mass of scaffold, m = 135 kg
mass of box, m' = 440 kg
let the tension in the left wire is T.
take moments about the right end.
According to the diagram,
135 x g x 3.3 + 440 x g x (6.6 - 1.7) - T x 6.6 = 0
4365.9 + 21128.8 - T x 6.6 = 0
T x 6.6 = 25494.7
T = 3862.8 N
Answer:
The no. of student failed is 36.
Step-by-step explanation:
Given, the number of student enrolled= 216
Let us suppose number of student failed = x
Given,
no. of student passed is 5 times no. of student failed.
Then, no. of student passed = 5x
x +5x = 216
6x = 216
x = 216/6
x = 36
Thus, the no. of student failed is 36.
