Find the missing length
jasenka [17]

Answer: 15

Step-by-step explanation:

For this you will have to use pythagoras’ theorem.

The formula for the shorter side of this triangle is u²=c²-b² (or in this case u²=17²-8²).

17²=289

8²=64

The formula becomes u²=289-64 or u²=225

Then to find u on its own you have to square root 225.

The square root of 225 is 15.

Answer:

The bag of chips and the pretzel are 14.

The cookie is 8.

The popcorn is 13.

"?" is 222.

Step-by-step explanation:

We know that the bag of chips and the pretzel are equal to each other so all we have to do to figure them out is to divide 42 by 3, which gets us 14.

So, now we know the bag of chips and the pretzel are both 14.

To figure out what the cookie is, we take 14 away from 30, which gets us 16. Two cookies are 16 which means that one cookie is 8.

To figure out what the popcorn is, we have to take away 16 from 29 since two cookies are 16. 29 minus 16 is 13.

Popcorn therefore is 13.

Two popcorns' is 26.

26 multiplied by 8 is 208.

208 plus 14 is 222.

Hope that made sense and answered your question! :)
