A wire of length 240 inches is cut into 2 equals pieces. Each piece of wire is then bent into forming an equilateral triangle an
Tamiku [17]
240 inches cut into 2 equal pieces is just taking half of the wire.
Making the two pieces of wire 120 inches. 
If you bend one 120 inch wire into a square, that means that each side equals 30 inches. (A square has 4 sides. 120/4 = 30)
An area of a square is length times width, which the length equals 30 and width equal to thirty. 30 * 30 = 900. square inches. 
120 wire bent into a triangle makes each side equal to 40. 120/3=40. The area of an equilateral triangle is height times width. The width is just one of the sides (40 inches) but the height needs some geometry. To find the height you need to use either 30 times sin(60) or 30 times cos(30), both are equal. To be clear, I will leave the height as 30sin(60). The area will be equal to 40*30sin(60)
which can be simply written as 1200sin(60). 
So the sum of both areas is (1200sin(60)+900)

natita [175]

Answer:

B) 2600

Step-by-step explanation:

Set up a proportional equation and solve:

220/300=x/3545

(220)(3545)=300x

779900=300x

2599.666=x

2600=x

Your best estimate is B) 2600

Ben has 57 toys.15 of them are new,9 are his favorite ones, 2 are new and favorite. Ben is going to give away all of his other t
Stells [14]

Answer:

31 toys

Step-by-step explanation:

What we know:

- There are 57 toys in total

- 15 are new

- 9 are Ben's favourite

- 2 are both Ben's favourite and new

Ben is not going to give away toys that are new or favourite. This means that the number of toys he <em>will not</em> give away is equal to 15+9+2.

15+9+2

= 26 toys

He has 57 toys in total, so we can find the number of toys he <em>is</em> going to give away by subtracting 26 from 57.

57-26

= 31 toys

Therefore, he will give away 31 toys.

I hope this helps!
