There is a hole in mr. smith's backyard. he wants to find out how wide the hole is. from the point where mr. smith is standing, he measures 20 and 25. how wide is the hole? a2 + b2 = c2 a) 10 b) 15 c) 20 d) 90

The answer is:

The correct option is:

B) 15

To solve the problem, we need to use the Pythahorean Theorem. We know that we can use the theorem since we are working with a right triangle as we can see in the picture.

So, we are given the following information:

Now, using the Pythagorean Theorem, we have:

Hence, we have that the correct option is:

B) 15

Have a nice day!

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

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.
