The length of an average toucan is about two thirds the length of an average macaw. Toucans are
about 24 in. long.
Answer:
36 in
Step-by-step explanation:
T= toucan

Find the perimeter of the figure to the nearest hundredth.
12 in.
5 in.
5 in.
9 in.
perimeter: about
in.
Answer:
50.28 inches
Step-by-step explanation:
From the Image, we can find the length of the arc of the semi-circle by dividing the circumference of the resulting circle by 2
Radius= 9in
C= 2πr
C=2*3.142*9
C=2*3.142*9
C= 56.556 inches
Hence the length of the arc is
=56.556/2
=28.278 inches
The perimeter of the shape
=28.278+5+12+5
=50.28 inches
Answer:
its actualy 50.26, but follow what the guy before me did.

k = 9/2 = 4.5
What is the difference between the number of solutions for a two-step equation and for a two-step inequality
Answer:
A two-step equation is something like:
A*X + B = C
In this case, like in a linear equation, we have only one solution that can be found as:
A*X = C - B
X = (C - B)/A
In the case of a two-step inequality, we have something like:
A*X + B > C
Solving this we get;
A*X > C - B
X > (C - B)/A
In this case, any value of X that is larger than (C - B)/A is a solution, so in this case, we have infinite solutions.
That is the difference between the number of solutions for each case, in a two-step equation we have only one, while in the case of the inequality we have infinite.

If the number of bacteria in a colony doubles every 27 hours and there is currently a population of 2,000 bacteria, what will the population be 54 hours from now?
Which of the following are parallel to
y = 3x – 2
(Choose all that apply)
y = 5 – 3x
Y= 3x
y = 3x – 1
y = 3x – 4
y = -3x
Answer:
y=3x-1,y=3x-4
Step-by-step explanation:
y=mx+c
where is gradient, parallel lines have same gradient
y=5-3x
=-3x+5
m=-3
y=-3x
m=-3
y=3x-1
m=3 ,the gradient is equal to the original equation
y=3x-4
m=3,the gradient also equal to the given equation
