Answer:
15
Step-by-step explanation:
Mia take 1/4 and 1/10 hours to create a bracelet. This is 1/4 + 1/10 = 10/40 + 4/40 = 14/40 = 7/20.
It takes her a total of 7/20 hours to make the bracelet. She has 5 1/4 hours to work. To find the number of bracelets she can make divide 5 1/4 by 7/20.
Write first 5 1/4 as a mixed number. 21/4. Then rewrite it as multiplication with the reciprocal of 7/20 to divide fractions.
21/4 * 20/7 = 420/28 = 15
She will make 15 bracelets.

The correct answer is A. All triangles' interior angles equal 180.
Answer:
-3 and 1
Step-by-step explanation:
The zero(root, range) of a parabola is where the parabola touches the x axis, here you can see that the parabola touches 1 and -3 on the x axis, hence that is the root.
Answer:
x = 111
Step-by-step explanation:
126+158+120+125+121+139 = 789
900-789 = 111
(n-2)*180
5*180 = 900
