Answer:
The answer to your question is the letter A.20%
Step-by-step explanation:
Data
Questions correct in the first attempt = 25
Questions correct in the second attempt = 30
Percent of increase = ?
Process
1.- Use proportions and cross multiplication to solve this problem. 25 questions is 100%.
25 questions -------------------- 100%
30 questions -------------------- x
x = (30 x 100)/25
x = 3000/25
x = 120 %
2.- Subtract 100 from 120%
Percent increase = 120 - 100
= 20%
The answer is 18... hope this helps :D

Answer:
x-intercepts: (2,0), (4,0)
y-intercepts: (0,-8)
Explanation:
To find the x intercept(s), you must compute where y=0. So solve 0= -x^2 + 6x - 8. So, the x intercepts are: (2,0) and (4,0) since the solutions to the mentioned equation are x=2 and x=4. To find the y intercept(s) compute what is y when x=0. In this case, when x=0, y=-8. So the only y intercept is (0,-8).
Answer:
Step-by-step explanation:
look at each picture to see what they are stating is the same in each of the triangles... the marks thur the lines means they are the same length, or the double or triple arcs in the angles means those are the same. so if there are two sides that are the same... you can say SSS , if there are two angles that are the same you can say ASA . the one where there is one side and one angle the same you can say SAS .... hmmm kinda get it?
