Answer:

1). a

2). b

3). c

4). d

Step-by-step explanation:

From the picture of a cone attached,

Radius of the circular top = r

Height of the cone = h

Slant height of the cone 'l' = 6

Area of the circular top of the cone with radius 'r' = πr²

Amount of space inside the cone = Volume of the cone = \frac{1}{2}\pi r^{2} h

The amount of wrapper needed to cover the side of the ice cream cone, not including the circular top of the cone = πrl = πr(6 in.)

The vertical height 'h' of the cone when the cone is standing upright = \sqrt{6^2-r^2}

[By Pythagoras theorem, l² = h² + r² ⇒ h = \sqrt{l^2-r^2}]

If three bags of birdseed cost $14.16, how much will 14 bags cost?
Rus_ich [418]
All the information's required for solving this problem is already given in the question.
The cost of 3 bags of birdseed = 14.16 dollars
Then
The cost of 1 bag of birdseed = (14.16/3) dollars
So
The cost of 14 bags of birdseed = (14.16/3) * 14 dollars
                                                    = 198.24/3 dollars
                                                    = 66.08 dollars
So from the above deduction we can see that the correct option is option "B". The cost of 14 bags of birdseed is $66.08. I hope the procedure is clear enough for you to understand.

Which fraction is equivalent to 2/5?  <br> A. 4/10 <br> B. 2/10   <br> C. 1/2   <br> D. 4/6
Lelechka [254]
Hey there James!

So, just remember, 2/5 is almost half of 1.

When it is almost half of 1, this means that it would have to be 2.5/5

This would mean that 4/10 would be your answer, because it is almost half of 1 also.

Hope this helps.
