Answer:
A. 9, 12, 15
Step-by-step explanation:
9, 12, 15 is a set of numbers that form pythagorean triple because it satisfies the equation, a² + b² = c².
Where, c is the longest side while a and c are the two other legs of the triangle.
Thus:
9² + 12² = 15²
225 = 225 (this is true).
If you begin with the basic equation of a vertical parabola: y-k=a(x-h)^2, where (h,k) is the vertex, then that equation, when the vertex is (-3,-2), is
y + 2 = a (x + 3)^2. If we solve this for y, we get
y = a(x+3)^2 - 2. Thus, eliminate answers A and D. That leaves B, since B correctly shows (x+3)^2.
Answer:
1/4, 0.25
Step-by-step explanation:
The reciprocal of a number is 1 divided by the number. 1/4=0.25.
76% would be your test score
Answer:
The answer is: there is 89.2% of the dog food remaining.
Step-by-step explanation:
Given: 31 1/4 lbs of dog food.
In one week - 3 1/8 lbs was used.
To find the amount left, subtract:
31 1/4 - 3 1/8 =
30 5/4 - 3 1/8 =
30 10/8 - 3/8 =
27 7/8 remaining.
To find the percent left, divide:
27 7/8 / 31 1/4 =
27.875 / 31.25 = .892.
Multiply by 100 to get percent:
.892 * 100 = 89.2% remaining.
Hope this helps!! Have an Awesome day!!! :-)
