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).

Yellow
12
Heads Tails

Using Victoria's simulation, what is the probability of pulling a blue marble and the coin landing tails up?
540/2500
48/50
38/50
360/2500

Answers

Answer: $(540)/(2500)$

Step-by-step explanation:

Formula:

$\text{Probability}=\frac{\text{Favorable outcomes}}{\text{Total outcomes}}$

Using Victoria's simulation :

Total number of outcomes = Total number of times marbles rolled x Total number of times coin flipped

= 50 x 50 =2500

Favorable outcomes = Total number of times pulling a blue marble and the coin landing tails up

= Number of times blue marble rolled x Number of times coin flipped to tail

= 18 x 30=540

Now, the the probability of pulling a blue marble and the coin landing tails up will be :-

$=(540)/(2500)$

Answer:

C. 540/2500

Step-by-step explanation:

18 times 30=540

50 times 50= 2500

Ax + c = R (solve for x)

Answers

Answer:

$x=(R-c)/(A)$

Step-by-step explanation:

Given equation,

$Ax + c = R---(1)$

For getting the equation for x,

We need to isolate x in the left side,

Subtract c on both sides of equation (1),

$Ax = R - c$

Divide both sides by A,

$x=(R-c)/(A)$

Which is the required equation.

Ax + c = R (subtract c from each side)

Ax + c - c = R - c

Ax = R - c (divide A from each side)

Ax/A = (R-c)/A

x = $(R-c)/(A)$ <-answer

Log4(6x-8)=3
Help please

Answers

The equation would be 4^3 = 6x -8 (Asmasharif49rihan, you forgot that this is a log problem, not a regular equation where you just distribute). Therefore, 6x - 8 = 64, 6x = 72, and x = 12.

first one 776 becasue you do half of 36 and then do to the cube and do 4/3
2) B because you need to to 5^3 then do 4/3 and multiply by 3.14
3)2350.87 because 8.25 ^ 3 then times 4/3 and multiplpy by 3.14
