Parallelogram abcd has the coordinates of a(-1,10) and c(5,4). Find the coordinates of where diagonals ac and bd intersect

Answer:

The coordinates of where diagonals ac and bd intersect at (2,7)

Step-by-step explanation:

we are given coordinates as a(-1,10) and c(5,4)

we know that diagonals of parallelogram always bisect each other

Let's assume O is the intersection point between diagonals

So, point O bisects line ac into two equal parts

So, point O is the mid-point of ac

so, we can find point O

we get

now, we can simplify it

and we get

So,

The coordinates of where diagonals ac and bd intersect at (2,7)

Jane and her friends are going on a hiking trip. Jane wants to make snack packs to take on the trip. She has 24 apples, 36 small bags of trail mix and 18 cans of juice. Each snack pack must have the same number of apples, bags of trail mix and cans of juice. What is the greatest number of apples that will be in each snack pack?

You didn't say how many friends so depending on say if 1 friend(s) went, then you would divide the lowest number by 2 and Jane and her 1 friend would each get 9 of each item in their bag. if it was 2 friends, then it would be 6 because 18 divided by 3 is 6. Hope I helped!

An electronics firm sells four models of stereo receivers, three CD decks, and six speaker brands. When the three types of components are sold together, they form a "system." How many different systems can the electronics firm offer? A. 169

B. 72

C. 13

D. 36

Answer:

B. 72
