Good morning,
Answer:
<h2>the area of THe bigger triangle equal to 80.</h2>
Step-by-step explanation:
There are 2 similar triangles with a ratio of 10-40 Then:
the area of THe bigger triangle equal to (40/10)²×(the area of THe smaller one)
then the area of THe bigger triangle equal to 4²×(the area of THe smaller one)
the area of THe bigger triangle equal to 16×(the area of THe smaller one)
the area of THe bigger triangle equal to 16×5
the area of THe bigger triangle equal to 80.

22/7 -2/3= 20/4
20/4×1/2=20/8
you need simplifly
so is 4/2
Answer:
16 and 4
Step-by-step explanation:
Let (x+y) =20 and (x-y)=12 then:
Isolate for x in each equation
x=20-y and x=12+y
Set the equations to equal each other since the value of x should be the same for both
20-y = 12+y
Rearrange so that y is on one side and the numbers are on the other
8 = 2y
y= 8/2
y= 4
Now substitute the y- value back into either of the original equations
x+y= 20
x+4 = 20
Rearrange and isolate x
x = 20-4
x = 16
So the two values are 16 and 4
1/3:no feathers or fur = fish
1/2: 4 legs =bear
1/6: left = birds
1/6 of the animals were birds.
