Of the 8760 hours in a year, one television was on for 2190 hours. What percent is this?

Answers

IS 25%, YOU FIND OUT BY DIVIDING 8760/100=87.60 WHICH REPRESENTS 1 PERCENT AND THEN 2160/87.60=25%
ALSO, IF YOU DIVIDE 8760/2190=4, SO THIS REPRESENTS 25%

What is 2.33 written as a mixed number in simplest form?A. 1002/33
B. 233/100
C. 2100/33
D. 233/100

Answers

The correct answer for the question that is being presented above is this one: "233/100". When the decimal 2.33 written as a mixed number in simplest form, then the answer will 233/100. You just move the decimal point in 2.33 two places to the right. Since, there are two decimal places, therefore the denominator should be 100.

A hyperbola has vertices (+-5,0) and one focus (6,0) what is the standard form equation of the hyperbola.

Answers

The standard form equation of the hyperbola:
x² / a² - y² / b² = 1
a = 5,
a² = 25
c = 6
c² = a² + b²
36 = 25 + b²
b² = 36 - 25
b² = 11
Answer:
x²/25 - y²/11 = 1

Final answer:

The standard form equation for this hyperbola, when vertices are (+-5,0) and one focus is (6,0), is x²/25 - y²/11 = 1.

Explanation:

In the question, we are given a hyperbola with vertices at (+-5,0) and one focus at (6,0). A hyperbola is defined by its distances from a given point to the two different foci, and its standard form equation along the x-axis can be written as

(x-h)²/a² - (y-k)²/b² = 1

, where (h, k) is the center of the hyperbola, a represents the distance from the center to each vertex, and b represents the distance from the center to each co-vertex. In this case,

h = 0

, since the center of the hyperbola is at the origin. The value of

a = 5

is the distance from the center to each vertex. Finally, the square of the distance c from the center to each focus is defined as

c² = a² + b²

, so we can find

b = sqrt(c² - a²)

. Here, c = 6, so b = sqrt(6² - 5²) = sqrt(11). Thus, the standard form equation of this hyperbola is

x²/25 - y²/11 = 1
