Let x be the number of sessions. Then
3/4x ≥ 12
3/4x + 3 ≥ 12
3/4x ≥ 9
x ≥ (9 x 4)/3 = 12
Therefore, 12 sessions remain to meet or exceed her weekly practice goal.
If 1 pint equals 2 cups then you would have 10 cups for 5pints.... 5 pints is the answer
Given - Taisha has a general goal is to burn the 280 calories.
she is varies by the 25 calories.
Find out the maximum and minimum of calories burn by the taisha.
To proof -
let us assume that the calories burn by the taisha be x.
as given the calories are varies by the 25 calories.
then the maximum calories equation becomes
x-25 = 280
x = 280 + 25
x = 305
the maximum calories burn by the taisha is 305 calories.
minimum calories equationbecomes
x + 25 = 280
x = 255
The minmum calories burn by the taisha is 255 calories.
Hence proved
Answer:
The equation of the ellipse is standard form is expressed as:
x²/81 + y²/9 = 1
Step-by-step explanation:
General equation of an ellipse is expressed as shown below:
x²/a² + y²/b² = 1
Length of the major axis = 2a
Length of the Minor axis = 2b
Given length of major axis = 18
18 = 2a
a = 9
Similarly, if the length of the minor axis is 6, then
6 = 2b
b = 3
The equation of the ellipse becomes;
x²/9² + y²/3² = 1
x²/81 + y²/9 = 1
Finding the LCM
(x²+9y²)/81 = 1
x²+9y² = 81
