Answer 1
Answer:

Answer:

JK = 24

Step-by-step explanation:

Δ BKJ and Δ BCA are similar triangles and ratios of corresponding sides are equal, that is

(JK)/(AC) = (BK)/(BC) , substitute values

(JK)/(40) = (3)/(5) ( cross- multiply )

5JK = 120 ( divide both sides by 5 )

JK = 24

Answer 2
Answer:

the triangles are all similar, because they have proportional sides and equal angles.

if you assume the smallest, equal part of side to be x

the biggest triangle has "5 parts" so BC=5x and BK has 3 parts so BK=3x .

since they're similar, ratio of their corresponding sides is constant or equal.

{BK\over BC}={JK \over AC}

BK/BC=3/5

and AC=40

so JK = 40*3/5=24

Trying to write an equation for line on graph without any numbers given to plug into for slope

In that situation, you use the information you DO have.  It's not always
enough to do the job.  But often it is, and in that case, you use what you
do have to answer the question or solve the problem.

Sadly, I can't be any more specific than that.  You haven't told us what
information you do have ... only what information you don't have.


Final answer:

The equation for the line is y = 3x + 9.

Explanation:

The equation for a line can be written in the form y = mx + b, where m represents the slope and b represents the y-intercept. In this case, since the slope is 3 and the y-intercept is 9, the equation for the line is y = 3x + 9.

He then unpacked 192 packs of frozen peas from 8 boxes.How many packs of frozen peas were in each box?

Answers

The question involves dividing the total number of packs (192) by the total number of boxes (8). The answer is 24 packs per box.

The subject of this question is Mathematics, and it's about the Division concept.

If a total of 192 packs of frozen peas were taken out from 8 boxes, we need to find out how many packs were in each box originally.

This can be done by dividing the total number of packs by the total number of boxes.

Therefore, you would do the calculation: 192 ÷ 8, which equals 24. So, there were 24 packs of frozen peas in each box.
