Answer:
Equation: 
when n = 4
Step-by-step explanation:
Given
Direct Variation: P ∝ n
When n = 15, P = 150
Required
Determine the equation
Her earnings if she sold 4 necklaces
P ∝ n
Convert variation to equation
When P = 150, n = 15 (Substitute these values in the given equation)
Divide both sides by 15
Substitute k = 10 in
------- Equation that relates P and n
When she sold 4 necklaces, n = 4
Substitute n = 4 in the formula above
Answer:
108units^2
Step-by-step explanation:
1) area of a trapezoid formula:
((a+b)/2)h
where a=base 1
b= base 2
h=height(24)
so
(8+1)/2=4.5
4.5*24=108
area is 108 units^2
1. I would multiply the dimensions of each room to find the area of each room. Then I can add up the areas to get the total area.
2. (24.5x16)+(15x12.75)+(10.5x10.5)
3. 392+191.25+110.25 = 693.5 ft²
