Which mathematical sentence most accurately expresses the information in the problem below? Crystal has 121 compact discs that s

ExtremeBDS [4]

Crystal has 121 compact discs. The total number of boxes required are 5.

Solution:

Given, Crystal has 121 compact discs that she wants to put into boxes.

Each of the boxes that she brought home holds 25 discs.

We have to find how many of these boxes will she need for all of her discs?

Now, we know that, number of boxes required $=\frac{\text {total number of discs}}{\text {capacity of one box}}=\frac{121}{25}=4.84=5$

Here we took 5 because 0.84 means that box with discs less than 25 still we require a box.

Hence, the total number of boxes required are 5.

Answer:

$FJ=18\ units$

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

If two triangles are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

In this problem

△FEG is similar with △FHJ -----> by AA Similarity Theorem

$\frac{FE}{FH}=\frac{FG}{FJ}$

we have

$FE=HF+EH=12+8=20\ units\\FH=HF=12\ units\\FG=30\ units$

substitute the given values

$\frac{20}{12}=\frac{30}{FJ}\\\\FJ=12(30)/20\\FJ=18\ units$
