Help me please for a test

 y = 24

Step-by-step explanation:

you need the pythagorean theorem(a^2 + b^2 = c^2)

so we have the hypotenuse so we plug in what we knowwhich is:  

10^2 + b^2 = 26^2     ->    100 + b^2 = 676

then solve for b^2

b^2 = 576   -> = 24

step-by-step explanation:

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
