Does anyone know this?
Neko [114]

"c" is the hypotenuse of the largest triangle, and "a" is that triangle's shortest side. Thus the ratio is

... (longest side)/(shortest side)


Since all the triangles in the figure are similar, to complete the proportion, you need to recognize the triangle that "a" is the longest side of, then find the shortest side of that triangle.


"a" is the longest side (hypotenuse) of the smallest triangle. The shortest side of that triangle is "r". So, your proportion is ...

... c/a = a/r


The appropriate choice is the 2nd one, ...

... r

Your realized income from your primary job is $3,076.45/month. Your fixed expenses are 36% of your realized income. How much mus
erastovalidia [21]
If you would like to know how much money you must save for an emergency fund of 6 months, you can calculate this using the following steps:

36% of $3,076.45 = 36% * 3,076.45 = 36/100 * 3,076.45 = $1,107.522

6 months * $1,107.522 = 6 * 1,107.522 = $6,645.132

The correct result would be $6,645.132.

Finger [1]

Answer:

J = 8

Step-by-step explanation:

multiply both sides of the equation by 4/3 = 4/3 × 3/4j = 4/3 × 6

Reduce the numbers with the greatest common factor 4 = 1/3 × 3j = 4/3 × 6

j = 4/3 × 6

j = 4 × 2

Multiply the numbers = j = 4 × 2

j = 8
