Answer:
Step-by-step explanation:
Vertex form of a quadratic equation is: y = a(x - h)² + k, where point (h, k) is the vertex
f(x) = 3(x - 2)² + 11
This is in vertex form, so the vertex is (2, 11)
*it's positive 2 because we are subtracting h in the equation, and we are subtracting positive 2 in our problem
We know, 1 oz = 28349.5 mg
so, 7 oz = 198447
So, it would be: 198447 * 2%
= 198447 * 0.02
= 3968.24 mg
In short, Your Answer would be 3968.24 mg
Hope this helps!
Answer:
10
12.5% less than 80 = 10
Step-by-step explanation:
Step 1: Our output value is 80.
Step 2: We represent the unknown value with x.
Step 3: From step 1 above, 80=100%
Step 4: Similarly, x=12.5%
For every 100 students, 72 prefer pizza.

Answer:
6 hours
Step-by-step explanation:
Let the labor hours be x.
The bill comprises of parts cost plus labor cost. Labor cost is hours times the cost per hour. Then we have equation:
- 265 + 48x = 553
- 48x = 553 - 265
- 48x = 288
- x = 288/48
- x= 6
So the answer is 6 hours.
