In the high school band there are 2 percussionists on the sidelines to every 13 marching instruments. if the high school band has 180 total members then how many percussionists are on the sidelines

Step-by-step explanation:

Let be "x" the number of percussionist that are on the sidelines.

The procedure to find "x" is:

1. There are 2 percussionists on the sidelines to every 13 marching instruments, then the sum is:

2. Knowing that the high school band has 180 total members, you can write the following proportion:

3. Finally, you must solve for "x" in order to find its value:

Therefore, there are 24 percussionists on the sidelines.

13

step-by-step explanation:

divide the cost of the total of sodas you bought by the cost of one soda, for example:

$24.57 divided by $1.89 is 13 which means you bought 13 sodas

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
