Which strategy best explains how to solve this problem? Colin is preparing for a marathon by running in his neighborhood. The first week, he runs one block. The next week, he runs twice as many blocks as the first week (2 blocks). Each week, he plans to run twice as many blocks as he ran the week before.

How many blocks will Colin run by the end of the sixth week?

A.
Use objects to model the problem.

Put out 1 chip to represent the blocks run in week one. Put out twice that amount for week two. Put out twice that amount (from week two) for week three. Do this 3 more times, putting out twice the amount from the previous week each time.

B.
Make a table.

In the first row, write first week - 2 blocks. In the next row, write second week - 4 blocks. In the third row, write third week -6 blocks. Continue this pattern for three more rows.

C.
Write a number sentence.

(1 + 2) × 6 = x
Add the number of blocks run in the first and 2nd week. Then multiply the sum by the number of weeks (6).

Here is the table
X | Y
_|__
1 | 2
2 | 4
3 | 8
4 | 16
5 | 32
6 | 64

Because if he runs twice as many blocks as the previous week, you have to multiply the previous week's number of blocks by 2.
You will have to ask someone else about the equation, though, because I'm not as good with the equations.

A is the best to use. B and C are if you're adding 2 instead of doubling :)

a manufacturer of cat toys produces three different toys filled with catnip the toys are the shape of a cone cylinder sphere each with radius 3 inches the cone and the cylinder each have a height of 2 inches which statement about the toys are true choose all that apply help ?

Answers

Statements A, B, and C are true.

Step-by-step explanation:

Step 1:

A cone, a cylinder and a sphere all have radii of 3 inches. The cone and cylinder have heights of 2 inches.

The volume of the cone, $V=\pi r^(2) (h)/(3).$ Here r = 3 inches and h = 2 inches.

So the volume of the cone $=\pi r^(2) (h)/(3) = \pi (3^(2)) (2)/(3) = 18.85$ cubic inches.

The volume of the cylinder, $V=\pi r^(2) h.$ Here r = 3 inches and h = 2 inches.

So the volume of the cylinder = $=\pi r^(2) h= \pi (3^(2)) (2) = 56.55$ cubic inches.

The volume of the sphere, $V=(4)/(3) \pi r^(3).$ Here r = 3 inches.

So the volume of the sphere $=(4)/(3) \pi (3^(3))= 113.1$ cubic inches.

Step 2:

Now we check to see which statements are true.

A. About 113 cubic inches of catnip will fit inside a sphere-shaped toy so it is true.

B. About 18.8 cubic inches of catnip will fit inside a cone-shaped toy so it true.

C. The sphere-shaped toy holds the most of the three so it is true.

D. No shape holds 169.6 cubic inches, so D is false.

E. The toys shaped like a cone and a cylinder do not hold the same amount of catnip in them. So it is false.

P.S. I couldn't see the options B, D, and E completely.

If the equation y=mx+b is used to model a quantity y as a function of the quantity x, why is b considered to be the starting value?

Answers

Answer:

This is because even when the quality of the variable x is 0, the value of b still exists and is the starting point for y.

Step-by-step explanation:

To prove this, we start with the base form of the equation and input 0 for x.

y = mx + b

y = m(0) + b

y = 0 + b

y = b
