Answer:
B. 4/3
Step-by-step explanation:
slope-intercept formula is y=mx+b, where m is the slope and y has to be by itself.
dividing 4 by 3 cant be more simplified than 4/3.
Based on the numbers we have we can assume that she saves 3 times more each week than the last (1*3=3, 3*3=9).
Following this trend we would multiply the amount she saved the third week ($9) by 3 to get $27 for the fourth week.
Then, we would multiply the amount she saved the fourth week ($27) by 3 to get $81 for the fifth week.
Finally, to figure out how much she saved in the 5 weeks, we need to add each value up to get 1+3+9+27+81= $121 saved in 5 weeks
Answer:
15 teachers
Step-by-step explanation:
Given:
number of children is c
number of teachers is t
= 
(rearrange)
t = 
x C
When C = 70,
t = x 70
t = 15 teachers
E^x^2 - 9 = 1
e^x^2 = 1 + 9 = 10
Ln e^x^2 = Ln 10
x^2 = Ln 10
x = sqrt (Ln 10) = 1.517
x = 1.517
