.
So we get
Answer:
7
Step-by-step explanation:
7.base of triangle=√(32.5²-28²)
=√4.5(32.5+28)
=√4.5(60.5)
=√272.25
=16.5
area of triangle=1/2 ×16.5×28
=231
volume=231×31=7161 km³
8.
39.4-25=14.4
width=√(30.6²-14.4²)
=√16.2(30.6+14.4)
=√16.2(45)
=√729
=27
volume=(25+39.4)/2 ×27×35
=(64.4)/2×27×35
=32.2×27×35
=30429 cm³
4.5. because ⁼3=9, and 9 divided by 2 is 4.5
A function assigns the values. The cost of 6 CDs will be $32.
<h3>What is a Function?</h3>
A function assigns the value of each element of one set to the other specific element of another set.
Given that the Recycled CDs. Incorporated, offers a choice of 5 used CDs for $27, with each additional CD costing $5. Therefore, a cost function for purchasing 5 or more CDs, where x represents the number of CDs over 5 can be written as,
C(x) = $27 + $5(x)
Now, if 6 CDs are purchased then the number of CDs that are more than 5 is 1. therefore, the cost of 6 CDs will be,
C(1) = $27 + $5(1)
= $27 + $5
= $32
Hence, the cost of 6 CDs will be $32.
