If BC = 5, DE = 9, and AB = 4, what is the length of AD?<br><br><br> 7<br> 8<br> 7.2<br> 7.5
steposvetlana [31]

There are two triangles here: ABC and ADF. These triangles are similar, and thus proportional. So, we can set up a proportion between the left side of each triangle and the base of each triangle.

AB / AD = BC / DE

4 / (4 + BD) = 5 / 9

---AD is made up of AB and DB. We know AB, but not BD, so we need to find its value to find the length of AD.

5(4 + BD) = 9 x 4

20 + 5BD = 36

5BD = 16

BD = 3.2

AD = AB + BD

AD = 4 + 3.2

AD = 7.2

Hope this helps!

Using the slope and the y-intercept, graph the line represented by the following equation. Then select the correct graph. 3y = 2
Over [174]
First, let's write the given equation in slope-intercept form: y = mx + b

In slope-intercept form, the slope of the line is m, and the y-intercept is b. The slope is a measure of how steep the graph is at any point and is found by doing rise over run. This means the change in y values divided by the change in x values. Next, y-intercept is just where the graph crosses the y axis.

All we need to do to get the equation in slope-intercept form is to divide each term by 3. This will isolate the y.

y= \frac{2}{3}x-2

As you can see, the slope of the line is 2/3, and the y-intercept is -2.

To graph the line, plot a point at (0,-2). This is the point where the graph crosses the y axis. Then from that point, count up two and right 3. Plot a point here as well. Lastly, connect the two points with a straight line.

See attached picture for the graph.

A farmer has a bale of hay with mass of 36 kilograms. How many milligrams of hay are in the bale?
Ilia_Sergeevich [38]

KILO=1000.............. MILLI= thousandth

1kg is 1000 grams

1 milligram is one thousandth of a gram, so a 1 gram = 1000mg.

in 36 kg, then there are 36 * 1000 grams.

and in (36*1000) grams there are (36*1000)*1000 mg, 36,000,000 mg.
