Answer:
The estimated taken to drive downtown using App is 38.4 minutes
Step-by-step explanation:
Given as :
The initial time taken to drive downtown = i = 48 minutes
The percentage error of time = r = 20%
Let The estimated time using app = t min
Let the time = 1 min
<u>Now, according to question</u>
The estimated time using app = The initial time taken to drive downtown × 
Or, t minutes = i minutes × 
Or, t = 48 minutes × 
Or, t = 48 minutes × 
Or, t = 48 minutes × 
∴ t = 
minutes
I.e t = 38.4 minutes
Or, The estimated time using app = t = 38.4 min
Hence, The estimated taken to drive downtown using App is 38.4 minutes Answer
Answer:
B
Step-by-step explanation:
(f+g)(x) means add f(x) and g(x) together:
(x/2)-2 + 2x^2 +x -3
collect all the like terms:
2x^2
(x/2) + x = 3/2x (explanation below)
-2 -3 = -5
x/2 + x can be turned to 1x/2 + 2/2x (2/2 = 1, so when you simplify it to 1x, it is still x)
Answer: It would cost $10 for 2 baseballs
Step-by-step explanation:
1.) You take 45 and divide it by 9 to find the cost of 1 baseball
2.) You then take the cost of a baseball and multiply it by 2
If there is 10% of $18 = 18 x 0.9 (1 - 0.1) = $16.20
Therefore the pie costs $16.20
He is saving 18 - 16.20 = $1.80
Since variables x and y are in direct proportion,
Y = 12.5/25 x 40
Y = 0.5 x 40
Y = 20.
