Answer:

2,176,782,336

Step-by-step explanation:

6 x 6 x 6 x 6 x 6 x 6 x 6 x 6 x 6 x 6 x 6 x 6 = 2176782336

217678336  let me explain

Step-by-step explanation: You have to multiply 6 every 12 times

6 x 6 =36

36 x 6 =216

216 x 6 =1296

1296 x 6 =7776

7776 x 6 =46656

46656 x 6 =279936

279936 x 6 =1679616

1679616 x 6 = 10077696

10077696 x 6 = 60466176

60466176 x 6 = 362797056

362797056 x 6 = 2176782336

Answer:

I notice in the compensation strategy it's much simpler than basic subtraction.

Step-by-step explanation:

Just say that ;)

When rounding, if the digit in the one's place is higher than 5, you round up. If it's lower than 5, you round down.

She's closer to 370m. Since the runner is at 368m and the digit in the ones place is higher than 5, you have to round up to 370. This means the runner is closer to 370m.

Hope this helps!

Answer: 65

Step-by-step explanation:

Answer: 20 would be in the column for 2, and 60 would be in the column for 6.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given function f(x), when you want to find f(4) you just put 4 for every x in the equation of the function.

f(x) = 3x + 5    ⇒    f(4) = 3(4) + 5 = 12 + 5 = 17

g(x) = 2x² - 4   ⇒    g(4) = 2(4)² - 4 = 2•16 - 4 = 32 - 4 = 28

h(x) = -3x - 9   ⇒    h(4) = -3(4) - 9 = -12 - 9 = -21

Answer:

19500 times in 26 mile race

Step-by-step explanation:

Answer:

none

Step-by-step explanation:

The first step you have to do is add 15 to both sides

so 12b > 36

next, you want to find out what b is so divide both sides by 12

b>3

As you represent this, you first want to find a line that is greater then three

this would be a because it is the only option that is greater then 3

However, because the dot is closed it can't be A so none of those options are correct

Tips:

if you are having trouble figuring out which lines are which remember that if the variable is on the left side of the equation to look at the sign. if you look at the sign then you see that the way the sign is going is also the way the arrow at the end of the line is going, but this trick only works if the variable is on the left side.

Answer: the awnser is B

Step-by-step explanation: First look at it nothing can be above 0 so if the graph has 1 before 0 its wrong then u have completed one step of the equation.

The data which satisfies the line is Option B.

The standard equation of a line is given by

y = mx+c

Here m is the slope and c is the y intercept

The slope can be determined by

m = (y₂ -y₁)/(x₂ -x₁)

The line passes through points (0, 0), (3, 1), and (6, 2).

m = 1/3

y = (1/3)x +c

c = 0

y = (1/3) x

The points in the table are substituted and then the data which satisfies is determined.

Column 1                                      Column 2

   X                                                              Y

-1                                                             -  3

0                                                                 0

1                                                                  3

2                                                                  6

This table satisfies the line.
