Step-by-step explanation:
By phythagorous theorem,
AC²=AB²+BC²
AC²=36+64
AC²=100
AC=root of 100
AC=10
15 × h
h= per hour
and to solve how many hours it would take:
600= 15 × h
600÷ 15 = 40
so it would take 40 hours to rise to the surface
Answer:
A = 846 in²
Step-by-step explanation:
The area (A) of a rhombus is calculated as
A = 
× d₁ × d₂ ( d₁ and d₂ are the diagonals ) , then
A = × 36 × 47 = 18 × 47 = 846 in²
The best and most correct answer providedfrom your question about the entrance examination paper is the second option which is 2,250. The problem can be solved by:
3-1-1 : 5c3*5c1*5c1 *3!/2! = 750
<span>2-2-1 : 5c2*5c2*5c1 *3!/2! = 1500
</span>
Adding the two answers:
750 + 1500 = 2250
I hope it has come to your help.
Divide both sides by 5, and the result is: x=30.
X is 30.
