Answer:
4.84% of trees on the island are poisonous.
Step-by-step explanation:
The proportion of fruit trees that are poisonous is the number of poisonous fruit trees divided by the total number of trees.
The percentage is the proportion multiplied by 100.
In this question:
60 poisonous trees.
1240 total trees.
60/1240 = 0.0484
0.0484*100 = 4.84%
4.84% of trees on the island are poisonous.
Answer:
[i] Area of Juan's garden:
Soln,
length(l)=16
width(w)=12
area(a)=?
Now,
a=l×w
=16×12
=192
[ii] Area of Matthew's garden:
Soln,
length(l)=18
width(w)=21
area(a)=?
Now,
a=l×w
=18×21
=378
So,the area ofJuan's garden=192
And
the area of Matthew's garden=378
Answer:
(E) 9
Step-by-step explanation:
I found what numbers worked in all three cases. I found that when a = 4 b = 5 c = 0, all of the equations were satisfied.
Equation 1 4 + 5 = 9
Equation 2 4 + 0 = 4
Equation 3 5 + 0 = 5
Also, a + b+ c or 4 + 5 + 0 = 9
