If there’s 18 pink butterflies then if you look at the ration for every 3 pink butterflies there are 5 yellow butterflies, so divide 3/18 to get 6 the multiply 6*5 to get 30 yellow butterflies
Answer:
Step-by-step explanation:
The area of a circle is A = πr², where r is the radius. That means in order to solve this we have to find the value of x, which is the diameter of the lake, and then divide it in half to get the radius. To find x we will use similar triangles and proportions. x is the height of the big triangle and 4.5 is the height of the smaller triangle; 15.3 + 7.4 is the hypotenuse of the big triangle and 7.4 is the hypotenuse of the smaller triangle. Setting up our proportion:
which simplifies a bit to
and cross multiply to solve for x:
7.4x = 102.15 so
x = 13.8 That is the diameter of the lake. Divide it in half to get 6.9, the radius. Applying the area formula for a circle:
A = (3.14)(6.9)² and
A = 3.14(47.61) so
A = 149.5 which rounds to 150, Choice C

<h3>What is Unitary Method?</h3>
Unitary method is a process by which we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.
Jon spent 1 hour 17 minutes less than Camden
Camden spent 47 minutes less than Pete.
Pete spent 3 hours reading.
Since, pete spent 3 hours. So, Camaden spent
= 3 hours or (180 minutes) - 47 minutes
= 2 hours 13 minutes.
Now, Jon spent = 2 hrs 13 minutes - 1 hour 17 minutes
= 56 minutes
