PLEASE HELP!<br><br> What is AD? <br><br> A. 15 <br><br> B. 12 <br><br> C. 3 <br><br> D. 20
ki77a [65]

Answer:

A. 15

Step-by-step explanation:

To solve this you need to compare the lengths given to you in the question statement.

Because the lines originate from a single point, they're like triangles.  We can easily see a triangle AGF and a triangle ADE, right?

Both triangles are similar triangles, so we can see triangle ADE as a larger version of angle AGF.

They give you the dimension of A F and A E (through A F + F E) to establish a ratio... and they give you A G, asking for A D.

So, A F = 16, A E = 20 (16 + 4), A G = 12.

Since A D is to A G what A E is to A F, we can easily make the following cross-multiplication:

\frac{A D}{A G} = \frac{A E}{A F}

So, A D = (A G * A E)/A F

A D = (12 * 20) / 16 = 15

denpristay [2]

Answer:

So far we know Jack has a bag of fruits and he if he randomly picks up a fruit from he will most likely get an apple. From this, we know that the percentage of an apple being picked is at least above 50%. And since it is likely we know it could be close to a 70 : 30 ratio.

-1 1/2 _ -1 3/4 which one is greater or less, or equal?
sleet_krkn [62]

Answer:

The answer is -1 1/2 is less than -1 3/4

Step-by-step explanation:

I look at it more as numbers, so for example 1/2 can be simplified into 50, and 3/4 is 75/ 75 would be greater if it was positive. But, with there being a negative 1 in front of the answer, the lowest number closest to 0 is better. :D
