Answer:
Step-by-step explanation:
Red blood cells : Platelets = 680 : 40 = (680÷10) : (40÷10)
= 68 : 4 = (68÷4) : (4÷4)
= 17 : 1
Answer:
Step-by-step explanation:
r and d are the radius and diameter of a, respectively.
area of a = πr² = 500 in²
r = √500/√π = 10√5/√π
d = 20√5/√π
radius of b = 3r = 30√5/√π
area of b = π(30√5/√π)² = π(4500/π) = 4500 in²
Answer:
i believe 1 is d but i’m not sure. very sorry if i’m wrong
Step-by-step explanation:
E=6
f=8
H=12
h=?
a=?


a=5


h=12.25
Area=0.5*e*f+4*a*h*0.5=0.5*6*8+4*0.5*5*12.25=146.5
Correct Question :-
- If y = - 7 & x = - 21 , determine x when y = 9
Given :-
We need to find :-
Solution :-
Using proportion ,
By means & extremes ,
=> - 7x = - 21 × 9
=> x = ( - 21 × 9 ) / - 7
=> x = 3 × 9
=> x = 27
Hence , when y = 9 → x = 27
