Answer:
18500 is the initial value
Every year they increase by a factor of 1.03
Step-by-step explanation:
This is written in the form
y = ab^x where a is the initial value and b is the growth rate/decrease
y = (18500) (1.03)^t
The initial value is 18500
The students will increase by 1.03 - 1 = .03
The factor of increase is what they multiply by which is 1.03
Let the number of girls be g and the number of boys be b.
b = 3g
Class average = class score/class size = 17
17 = (class score) / 3g + g
68g = class score
Class score = girls score + boys score
Girls average = girls score/g
girls score = 18g
68g = 18g + boys score
boys score = 50g
Boys average = 50g/3g
= 16.7
Volume = length x width x height
Volume = 8 x 8 x 18
Volume = 1152 in^3
Determine if the following equations are linear or non-linear. Circle your answer and describe why. 7. 2. 3. = + y x linear non-linear. 5. 3.
So with the given information, I make the length equal x and the width equals x+61. Remember a rectangle has two pairs of equal sides.
So then the equation is 4x+122=406
Do systems and you will find that x equals 71.
The length is 71cm
The width is 71+61=132cm
