19/25 = x/100
Cross multiply:
1,900
Divide 1,900 by 25
Equals 76
Subtract 76 from 100
Answer: 24% change
I hope this helps!
First how many times does 25 go into 100? 4 right? So now multiply 9x4= 36. 36 % voted for Maria
Answer:
Step-by-step explanation:
if the base=x
length of one leg is =4x-6
length of the other leg is also =4x-6 (isosceles)
P=x+4x-6+4x-6=51
9x-12=51
9x=51+12
9x=63
x=63/9=7
x=7
Answer:
x (distance) = 10, max height = .75
Step-by-step explanation:
y=-.03x(x-10)
The distance are the x intercepts: 0 and 10, where 0 is time started and 10 is time ended.
Expand the equation:
y=-.03x^2 +.3x
To find max height you find the vertex
x = -b/2a
x = -.3/-.06 = 5
Plug the x into the equation
y=.-03(5)^2 +.3(5)
y=.75
