Answer:
Carlos and Pamela drove 120 miles on the first day, 240 miles on the second day, and 290 miles on the third day.
Step-by-step explanation:
Let x be the number of miles driven on the first day.
Then they drove twice as many miles, or 2x on the second day
and 50 miles more than the second day's, so 2x + 50
The total is 650 across all three days, so we'll take the sum.
x + 2x + (2x + 50) = 650
Combine like terms on the left
5x + 50 = 650
Subtract 50 on both sides
5x = 600
Divide by 5 on both sides
x = 120
Check work:
120 + 2(120) + 2(120) + 50 = 650
120 + 240 + 240 + 50 = 650
600 + 50 = 650
650 = 650
So they drove 120 miles on the first day
2*120 = 240 miles on the second day
and 2*120 + 50 = 240 + 50 = 290 miles on the third day
Answer:
answers are given below
Step-by-step explanation:
1.
Circumference = 
Where 2r = Diameter
Hence
Circumference = 
2.
No there is no such circle in which relationship between Radius and Diameter can be represented without 
.
This is because while deriving the relation the angle measurement ts taken into consideration and the angle are measured in radians i.e. in terms of not degrees.
3. We can not determine the exact circumference because 
is a rational number and but its value is approximately taken from and is an irrational number
Answer:
10%
Step-by-step explanation:
First find the difference in the 2 prices
44-40=4
Divide the original price by the difference
difference/original
4/40=0.1
0.1*100=10
Hope this helped!
