Alexxandr [17]

According to time, texting speed is a two-variable type of data that's represented by a scatterplot. This is because a scatterplot helps graph the data points, so that you can figure out and interpret the relationship.

The other answer is the sample response, so it's better to put it in your own words. :)

Find the area of the figure to the nearest thousandth
CaHeK987 [17]

Answer:

236.715\:\mathrm{ft^2}

Step-by-step explanation:

The area of the figure consists of a rectangle and two half-circles.

Area of rectangle: 15\cdot 4=60

Area of two half-circles: 2\cdot \frac{1}{2}\cdot 7.5^2\cdot \pi=176.714586764

Thus, the total area of the figure is

60+ 176.714586764\approx \boxed{236.715}

What is the justification for each step in the solution of the equation?
Alexandra [31]

For this case we have the following equation:

\frac{2}{3}x-\frac{1}{3}= 2 (x + 2)\\

If we multiply both sides of the equation by 3 we get:

2x-1 = 6 (x + 2) ---> Multiplication Property of Equality

Applying the distributive property we have:

2x-1 = 6x + 12 ---> Distributive Property

Adding 1 on both sides of equality we have:

2x-1 + 1 = 6x + 12 + 1\\

2x = 6x + 13 ---> Addition Property of Equality

Subtracting 6x on both sides we have:

-6x + 2x = 6x-6x + 13\\

-4x = 13 ---> Subtraction Property of Equality

Finally, dividing by -4 on both sides we have:

\frac{-4x}{-4}= \frac{13}{-4}\\

x = -\frac{13}{4}---> Division Property of Equality
