Answer:
should be left in the candy bar.
Step-by-step explanation:
Jenn and David shared a candy bar. Let's assume the bar was split into 10 parts, since 10 is the denominator of the fraction.
First, we need to add how much that the candy bar was eaten so we can subtract easier.
Jenn ate three tenths.
David ate four tenths.

So, seven tenths of the candy bar was eaten. We need to subtract that from a whole, because we need to know how much candy is left.

So, there are 3/10, or 0.3, of the candy bar left to share later.
Yes, all triangles have at least two acute angles. If there were two right angles, it would not be a closed figure. If there were two obtuse angles, there would be more than 180 degrees.
Hope this helps =)
4 out of 50 is what percent
4/50 is what percent
percent mens parts out of 100
x%=x/100
4/50=x/100
multiply both sides by 100
8=x
answer is 8%
The equation is y = 1/2 x + 13, where x is the number of days, and y is the length of the barrier
