Answer:
a. $435
b. 33.33%
Step-by-step explanation:
P.S - The exact question is -
Let Clara raised money = x
As given,
Ali raised 20% more than Clara
⇒Ali raised money = 
Also given,
Clara raised 
times more than Shan
Clara raised money = Shan raise money + times shan raired money
⇒Clara raised money = 
Shan raised money
⇒Shan raised money = 
times Clara
⇒Shan raised money = x
As given,
Ali raised $58 more than shan
⇒
⇒
⇒
⇒x = (29)(5) = $145
∴ we get
Clara raised money = x = $145
Ali raised money = 
= $174
Shan raised money = x = $116
a.)
Total raised money = $145 + 174 + 116 = $435
b.)
Percentage of money Clara raised = 
×100% = 
×100% = 33.33%
The volume of a cone is always 3 times smaller than that of its corresponding cylinder (that is, a cylinder with the same height and base radius).
As in:
Volume of a cylinder= πr²h
and Volume of a cone=⅓πr²h
But just in case you were referring to an actual difference, then that would be ⅔πr²h, since 1—⅓ = ⅔.
C. There are many solutions
4(5)-1=19

Answer:
1. b. The common difference is 0.39
2. no good answer (Zach's method is exponential; Victoria's is linear)
Step-by-step explanation:
1. The differences in mileage are ...
24.39 -24 = 0.39
24.78 -24.39 = 0.39
25.17 -24.78 = 0.39
The common difference is 0.39.
____
2. Zach's monthly times are ...
10, 20, 40, 80
The differences are ...
10, 20, 40
The ratios are ...
20/10 = 40/20 = 80/40 = 2
Zach's times have a common ratio, so are exponential.
__
Victoria's monthly times are ...
35, 50, 65, 80
The differences are ...
15, 15, 15
Victoria's times have a common difference, so are linear.
__
The choices are ...
a. both exponential; common factor . . . . correct for Zach; not for Victoria
b. Zach's is linear (has equal factor) . . . incorrect
c. both exponential; common difference . . . incorrect
d. Victoria's is linear . . . . correct for Victoria
Choice D describes Victoria's method. Choice A is correct regarding Zach's method, but incorrect regarding Victoria's.
Choices B and C are not self-consistent, so are incorrect on their face.
There is no good choice.
F(4)=4(4)+5
Which equals
F(4)=21
