Answer:
The number is 20
Step-by-step explanation:
Let the number be x
5(x - 9) = 2x + 15
5x - 45 = 2x + 15
5x - 2x = 15 + 45
3x = 60
x = 60/3
x = 20
Answer:
5mm
Step-by-step explanation:
using the formula of volume of cone i.e. 1/3 ×πr²h
1/3 × πr²h = 314
or, r²= (314×3)/ (π×h)
or, r² = 25
r= 5 mm
Answer -2 + x / 2
Step-by-step explanation:
3:4=0.75
6:8=0.75
just divide both of them and you will get the answer, so yes
Interest = p times R times T
