Answer:

She will have stretched her neck 1 time, she will have stretched her legs 2 times, and she will have stretched her arms 4 times.

Step-by-step explanation:

This is because 1/2 can only go into 2/3 once, 1/3 can go into 2/3 twice, and 1/6 can go into 2/3 four times.

15. The container shown in the figure is filled with a liquid that weighs 50 g. Find its density.
3241004551 [841]

Answer:

  C.  0.006 g/cm³

Step-by-step explanation:

As the units tell you, density is the ratio of mass to volume. The volume of the container is found from ...

  V = πr²h = π(10 cm)²(25 cm) = 2500π cm³

Then the density is ...

  ρ = (50 g)/(2500π cm³) = 1/(50π) g/cm³

  ρ ≈ 0.006 g/cm³

_____

<em>Comment on the problem</em>

The "liquid" has about the same density as air pressurized to 75 psi.

<h3>Answer: Choice B) </h3><h3>-6x - 2y = 12</h3>

===============================================

Explanation:

The x intercept is (-2,0) which is where the graph crosses the x axis.

The y intercept is (0,-6) which is where the graph crosses the y axis.

-----

Find the slope of the line through those two points

m = (y2-y1)/(x2-x1)

m = (-6-0)/(0-(-2))

m = (-6-0)/(0+2)

m = -6/2

m = -3

-----

The y intercept (0,-6) leads to b = -6

Both m = -3 and b = -6 plug into y = mx+b to get

y = mx+b

y = -3x+(-6)

y = -3x-6

-----

Now add 3x to both sides

y = -3x-6

y+3x = -3x-6+3x

3x+y = -6

-----

Lastly, multiply both sides by -2 so that the "-6" on the right hand side turns into "12" (each answer choice has 12 on the right hand side)

3x+y = -6

-2(3x+y) = -2(-6)

-2(3x)-2(y) = 12

-6x-2y = 12

which is what choice B shows.

MArishka [77]

The range for Week 1 equals he range for Week 2 is the true statement.

Answer: Option A.

<u>Step-by-step explanation:</u>

Median is the middle number of an ordered list.

75 is the median for Week 1 and Week 2.

The range is the difference between highest and lowest value for the given number series.

The highest and lowest value of the series for both Week 1 and Week 2 is same.

Lowest value =62.

Highest value =89.

∴ The range for Week 1 and Week 2 = 89-62.

The range for Week 1 and Week 2 = 27.

∴The range for both Week 1 and Week 2 remains the same.
