Let the original number be ‘x’
Then half of that number= 1/2x or simply x/2
Similarly one fifth of that number = x/5
According to the question
x+x/2+x/5=51
Taking LCM
10x/10+2x/10+5x/10=51
Multiplying 10 throughout
10x+2x+5x=510
17x=510
x=510/17
Therefore x=30
Answer:
x(y² - 4) = 1.512
Step-by-step explanation:
We need to evaluate the following expression for x = 0.2 and y = 3.4 :
x(y² - 4)
Put the values of x and y.
x(y² - 4) = (0.2)((3.4)² - 4)
= (0.2)((3.4)² - 4)
= 0.2×7.56
= 1.512
So, the value of the above expression is 1.512
Answer:
72
Step-by-step explanation:
Volume for a triangular prism = a · c · h
A = Height. C = Width. H = Length.
A = 3 yd. C = 8 yd. H = 6 yd.
V = 114 yd.
V = 114 yd ÷ 2 yd = 72 .
