Answer:
a = 120 cm²
Step-by-step explanation:
n = number of sides
edge length
40/n
divide the polygon into n congruent triangles
a = (1/2)(edge * apothem) * number of triangles
a = (1/2)(40/n)(6) * n
n cancels out
a = (1/2)(40)(6)
a = 120 cm²
Answer:
The rate at which how many tokens a person loses per minute.
Step-by-step explanation:
If we move around the terms in the equation to fit standard form, it will be easier to determine the slope.
y = 50 - 2x
y = -2x + 50
We know that the slope is the coefficient of the x variable, so m = -2 or .
Since the slope is negative, we know that the line will go down as x increases. Since the slope is multiplied by the number of minutes x, we know that the slope represents the typical rate at which a guest spends tokens per minute. In simpler words, how many tokens a person loses every minute.
Answer:
Using the form y = m x + b where b is the y-intercept and m the slop
1. 6.85 is the y-intercept- when c = 0 the value of y will be 6.85
2. the slope here is m = 2.95 that means for every increase of 1 on the x-axis which is c the value of y increases by 2.95 (additional cost of each child)
3. If no children were to go the cost would be 6.85 (c = zero)
So she paid 18.65 - 6.85 = 11.8 for the children that went
11.8 / 2.95 = 4 so 4 of her grandchildren attended
