Answer:
87.5 percent
Step-by-step explanation:
when you have to increase a number by 50 percent you are multiplying it by 1.5
later when you increase the number by 25 percent you multiply it by 1.25
you can multiply 1.5 by 1.25 to get your answer
1.5 * 1.25 is 1.875
so the percent increase is 87.5 percent

Answer:
2 + 2w
w = 9.3in
l = 20.7 in
Step-by-step explanation:
Perimeter of a rectangle = 2 x (length + breadth)
legnth = 2 + 2w
width = w
2 x (2 + 2w + w ) = 60
(2 + 2w + w ) = 30
2 + 3w = 30
3w = 28
w = 9.3
length = 2 + 2x9.3 = 20.7
Answer:
To convert a quadratic from y = ax2 + bx + c form to vertex form, y = a(x - h)2+ k, you have to Get ready to create a perfect square trinomial. BUT be careful!! In previous completing the square problems with a leading coefficient not 1, ... Take half of the coefficient of the x-term inside the parentheses, square it, and place it in the box.
hope this helps :)
Answer:
4 (5/12). four and five-twelfths
Step-by-step explanation:
1/2 is the same as 2/4, so: 1 1/2 = 1 2/4
1 2/4 + 2 1/4 = 3 3/4
3/4 and 2/3 have a LCM or least common multiple of 12
4 x 3 = 12 and 3 x 4 =12; but whatever you do to the bottom you have to do to the top (3/4) turns into (9/12) and (2/3) turns into (8/12)
9/12 + 8/12 = 17/12 or 1 5/12 as a mixed number
3 + 1 5/12 = 4 5/12
