Answer:
<h2>The answer is 15cm</h2>
Step-by-step explanation:
Let b be the length of the second parallel side
Area of a trapezium is given by
where
h is the height
a and b are the parallel sides
From the question
Area = 230 cm²
height = 20cm
one of parallel side / a = 8 cm
Substitute the values into the above formula and solve for b
That's
Reduce the fraction with 2
That's
Expand the terms
That's
Divide both sides by 10
We have the final answer as
<h3>b = 15cm</h3>
Hope this helps you
First let as solve all unit pirce
whistles 21.25 / 25 = $ 0.85 per unit
36 / 50 = $ 0.72 per unit
60 / 80 = $ 0.75 per unit
kazoos
10 / 25 = $ 0.4 per unit
18.50 / 50 = $ 0.37 per unit
27.20 / 80 = $ 0.34 per unit
a.) $ 0.85 - $ 0.72 = $ 0.13
b.) 10 / 25 = $ 0.4 per unit
c.) he must order 80 kazoos she should order
T(n) = 0.2n

The volume of the sphere would be 149.42m³
The answer is 0.52 s
The function is t = 0.005x² + 0.002x
x = 10
Substitute x into the function:
t = 0.005 * 10² + 0.002 * 10
t = 0.005 * 100 + 0.02
t = 0.5 + 0.02
t = 0.52 s
