The first digit can only range from 1-9, resulting in 9 possible options. The last digit can only be 2, 4, 6, and 8, resulting in 4 possible options. The other four digits can range from 0-9, resulting in ten options for each. Using the fundamental counting principle, we can use the following equation to solve for the different amount of codes possible.
9 \times 10 \times 10 \times 10 \times 10 \times 4 \\ 360000

Rewrite the expression as a multiple of a sum of two numbers with no common factor 15+24 _____
nata0808 [166]
<span>To rewrite the expression as a multiple of a sum of two numbers with no common factor, we're supposed to find the greatest common factor between the terms and factor it out. </span>We can see that both 15 and 24 are divisible by 3. So let's factor the 3 out. Since the 3 goes into 15 five times and into 24 eight times, the expression can be rewritten like this.

15 + 24 = 3(5 + 8)

What is the surface area of the figure shown? (Use 3.14 for π.)
Ivanshal [37]
We know that
Part 1) 
[surface area of a cone without base]=<span>π*r*l
r=3 in
l=slant height ----> 6 in
</span>[surface area of a cone without base]=π*3*6------> 56.52 in²

[surface area of a cylinder]=π*r²+2*π*r*h------> only one base
r=3 in
h=5 in
[surface area of a cylinder]=π*r²+2*π*r*h
[surface area of a cylinder]=π*3²+2*π*3*5-----> 122.46 in²

[surface area of the composite figure]=56.52+122.46-----> 178.98 in²

the answer Part A) is
 178.98 in²

Part B) 
[surface area of the composite figure]
=12*16+2*12*7+2*16*7+5*12+5*16+13*16----> 932 ft²

the answer Part B) is 
 932 ft²
