How many seconds on a day

Mathematics

Answer:

There are 86,400.

Step-by-step explanation:

This is because there are 60 seconds in one minute. Then you need to times 60 by 60 to see how many seconds there are in a hour. Then you times that by 24 because there are 24 hours and that is your answer. I will show my work below:

60 (how many seconds there are in a minute)

60 (how many minutes there are in a hour)

24 (how many hours there are in a day)

60 x 60 (for the amount of seconds there are in a minute and how many minutes in a hour). Which 60 x 60 = 3600

Then, take that seconds in a hour and times it by 24 because there isn't 1 hour in a day, and it isnt asking how many seconds are in a hour, it is asking how many seconds there are in a DAY.

3600 x 24 = 86400

So, there are 86,400 seconds in one day! :D

Good luck on your test!

Answer:

86 400

Step-by-step explanation:

Using the conversions

1 minute = 60 seconds

1 hour = 60 minutes

1 day = 24 hours, then

seconds in a day = 60 × 60 × 24 = 86 400

an ellipse has a center at the origin , a vertex along the major axis at (13,0), and a focus at (12,0). What is the equation of
-BARSIC- [3]

Answer:

The answer to your question is below

Step-by-step explanation:

Data

Center = (0, 0)

Vertex = (13, 0)

Focus = (12, 0)

Process

From the data we know that it is a horizontal ellipse.

1.- Calculate "a", the distance from the center to the vertex.

                  a = 13

2.- Calculate "c", the distance from the center to the focus

                  c = 12

3.- Calculate b

Use the Pythagorean theorem to find it

                  a² = b² + c²

-Solve for b

                  b² = a² - c²

-Substitution

                  b² = 13² - 12²

-Simplification

                  b² = 169 - 144

                  b² = 25

                  b = 5

4.- Find the equation of the ellipse

                       \frac{x^{2} }{13^{2}} + \frac{y^{2}}{5^{2}} = 1    or \frac{x^{2} }{169} + \frac{y^{2}}{25} = 1
