Add the numbers in the series 3+11+19+27+.....+395+403.

Answers

Answer 1
Answer:

Answer:

10353

Step-by-step explanation:

The given series is in arithmetic progression since the common difference is same which is 8.

To find the sum of series we can simply apply the formula'

S= n/2( first term + last term)

S is the sum and n is the number of terms

we also need to find the number of terms n

n = (last term- first term)/2 + 1

n= (403-3)/(8) + 1

n= 51

s= (51)/(2)(3+403)

s= 10353

Driving along, terry notices that the last four digits on his car's odometer are palindromic. a mile later, the last five digits are palindromic. after driving another mile, the middle four digits are palindromic. one more mile, and all six are palindromic. what was the odometer reading when terry first looked at it? form a linear system of equations that expresses the requirements of this puzzle.

Answers

Designate the initial digits, left to right, as {a, b, c, d, d, c}.

After adding one mile, the digits are {a, b, c, d, c, b}, so the relevant equation is
  10c +b = 10d +c +1

After adding another mile, the digits are {a, b, c, c, b, e}, so the relevant equation is
  100c +10b +e = 100d +10c +b +1

After another mile, the digits are {a, b, c, c, b, a}, so the relevant equation is
  a = e +1

In summary, we have 3 equations in 5 unknowns.
  b + 9c -10d = 1
  9b +90c -100d +e = 1
  a - e = 1
along with the constraints {a, b, c, d, e} ∈ {0, ..., 9}


_____
These have the solution {a, b, c, d, e} = {1, 9, 8, 8, 0}, so the odometer readings were

During an experiment, the temperature of a substance increased at a constant rate of three degrees Celsius (°C) per hour. Which graph represents this relationship?

Answers

A graph which represents this relationship between the temperature of a substance and time is shown in image.

What is a graph?

In Mathematics, a graph can be defined as a type of chart that is typically used for the graphical representation of data points on both the horizontal and vertical lines of a cartesian coordinate, which are the x-coordinate (x-axis) and y-coordinate (y-axis).

In Science, temperature can be defined as a measure of either the degree of hotness or coldness of a physical body (object).

Since, the temperature of a chemical substance increased at a constant rate of three degrees Celsius (3°C) per hour, a graph which represent the relationship that exist between the temperature of a substance and time is shown in the image attached below.
