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.
Answer:
<h3>4.84*10^-4hours</h3>
Step-by-step explanation:
Speed = Distance/Time
Time = Distance/Speed
Given
Distance = 1.2m = 0.012cm
Speed = 24.8cm/hr
Get the time;
Time = 0.012/24.8
Time = 4.84*10^-4hours
Hence it will take the water 4.84*10^-4hours to reach the top of the dock
Answer:
$1875
Step-by-step explanation:
Given the information:
- An apartment costs: $625 per month
- They require that the cost of rent be no greater that a third of his monthly income
- The must earn at least 3 times the cost of his rent
=> the smallest amount of money that Carlos needs to make per month to be approved to move in:
= 3 times of $625
= 3*$625
= $1875
because 625 is exactly 1/3 of $1875

Answer:
m>11
Step-by-step explanation:
2*(m+3)-(-5+3*m)<0
STEP1:
2 • (m + 3) - (3m - 5) < 0
STEP2:
11 - m < 0
STEP3:
Multiply both sides by (-1)
Flip the inequality sign since you are multiplying by a negative number
m-11 > 0
