Answer:
option a
Step-by-step explanation:
95 +x=180
x=180-95=85
85+31+y=180
116+y=180
y=180-116=64

Answer:
See below
Step-by-step explanation:
<em>Quadratic function is in general form of:</em>
- <em>y = ax^2 + bx + c</em>
<em>The function has a minimum if a > 0 and maximum if a < 0</em>
<em>The minimum or maximum point is a vertex of the graph</em>
- <em>A vertex is the point x = -b/2a</em>
<em>When b = 0, the min or max point equals to value of c.</em>
- 33. It has maximum of -1
- 34. It has minimum of 7
- 35. It has minimum at x = - 8/4 = -2
f(-2) = 2*(-2)^2 + 8(-2) + 7 = 8 - 16 + 7 = - 1
- 36. It has maximum at x = -18/2(-3)= 3
g(3) = -3*3^2 + 18*3 - 5 = -27 + 54 - 5 = 22
- 37. It has minimum at x = - 6/(2*3/2) = - 2
f(-2) = 3/2*(-2)^2 + 6(-2) + 4 = - 6 - 12 + 4 = - 14
Answer:
25
Step-by-step explanation:
Each of the 16 "ratio units" representing all 80 dancers must stand for ...
(80 dancers)/(16) = 5 dancers
Then 5 "ratio units" representing seventh-grade dancers will stand for ...
5 × 5 dancers = 25 dancers
___
Another way to figure this is to write the proportion ...
(seventh-grade dancers)/(all dancers) = 5/16
seventh-grade dancers = (all dancers)×(5/16) = 80×5/16
seventh-grade dancers = 25
Answer:
.03472
Step-by-step explanation:
take sell price $20. subtract cost of 11.32 which equals 8.68. then divide 8.68 by the sell price $20
The formula for contribution margin is the sales price of a product minus its variable costs. In other words, calculating the contribution margin determines the sales amount left over after adjusting for the variable costs of selling additional products.
