Since 15 workers did 8 hours of work, the total amount of work needed is 120 hours. Half of this job would be 60 hours. Then divide this amount by the 5 workers doing the job. This would make the job 12 hours

J=15w*8h=120(worker*hours)

5h=120/2

5h=60

h=12 hours

What type of triangle is defined by the following set of side lengths
NARA [144]

Answer:

<u>ACUTE</u><u> </u><u>TRIANGLE</u><u> </u>

Step-by-step explanation:

If the sum of the squares of the two shorter sides of a triangle is greater than the square of the longest side, the triangle is acute. However, if the sum of the squares of the two shorter sides of a triangle is smaller than the square of the longest side, the triangle is obtuse.

Therefore, the triangle with sides 11, 9, and 7 is an acute triangle since 9² + 7² is greater than 11²

{9}^{2}  \:  +  \:  {7}^{2}  >  \: {11}^{2}  \\ 130 > 121

Daniel [21]

Okay so f(n) is the range and n is the domain. The graph should be inclined up crossing (0,0).  The domin is (0, infinity) because is she woulds 0 hours then Julia will get paid $0 so it starts at 0 and goes to inifinity.

A book with a yellow sticker costs 50cents more than double a book wit3a red sticker
navik [9.2K]

Answer:

50b>100b

Step-by-step explanation:

the book (b) is your variable in this case (a variable is just an item and im using b because it stands for books lol)

the book costs 50 cents, so we are going to put 50 cents in front of b(the books) so like this---->  50b: this reads as "the books are 50 cents."

now, the "more than" always means this sign ">"

and here's the tricky part, since it says " double a book with a red sticker." you're going to want to multiply ( 50*2=100), and we do this because of the word "double" (double means two) this is how you would write this scenario.

now im not sure if you wanted me to solve for it, but if curious you would just have to divide. the 50 and the 100 to get an answer.
