The least common denominator of 3/2 and 2/3

Inscribe a circle in a unit square and to r= 1000 random.

Oduvanchick [21]

Step-by-step explanation:

area of square = 1

area of a circle in square = $\pi r^2 = \pi *(1/2)^2 = \frac{\pi }{4}$

bu estimate $p^ = X/n = 760/1000 = 0.76Therefore, 
[tex]\frac{\pi }{4} \approx 0.76$

$\pi \approx 0.76*4 =3.04$

b) if n tend to infinity

$\pi will approach 3.14$

Emily ran her first lap in 75 seconds she ran her second lap in 69 seconds using percentages how much better was her second lap

julsineya [31]

Answer:

Her second lap was 8% better when compared to her first lap.

Step-by-step explanation:

Given:

Emily ran her first lap in 75 seconds she ran her second lap in 69 seconds.

Now, to find how much better was her second lap when compared to her first lap.

Emily ran her first lap in 75 seconds.

Emily ran her second lap in 69 seconds.

So, we get the difference in seconds:

$75-69=6\ seconds.$

Thus, in her second lap she was 6 seconds better than first.

Now, to get the percentage of her first lap better than second:

$\frac{6}{75}\times 100$

$=0.08\times 100$

$=8\%.$

Therefore, her second lap was 8% better when compared to her first lap.

Determine the expression you can substitute for y in to solve the system below.

FromTheMoon [43]

Answer:

Step-by-step explanation:

given are the two following linear equations:

f(x) = y = 1 + .5x

f(x) = y = 11 - 2x

Graph the first equation by finding two data points. By setting first x and then y equal to zero it is possible to find the y intercept on the vertical axis and the x intercept on the horizontal axis.

If x = 0, then f(0) = 1 + .5(0) = 1

If y = 0, then f(x) = 0 = 1 + .5x

-.5x = 1

x = -2

The resulting data points are (0,1) and (-2,0)

Graph the second equation by finding two data points. By setting first x and then y equal to zero it is possible to find the y intercept on the vertical axis and the x intercept on the horizontal axis.

If x = 0, then f(0) = 11 - 2(0) = 11

If y = 0, then f(x) = 0 = 11 - 2x

2x = 11

x = 5.5

The resulting data points are (0,11) and (5.5,0)

At the point of intersection of the two equations x and y have the same values. From the graph these values can be read as x = 4 and y = 3.
