Answer:
5.78 x 10^-2
Step-by-step explanation:
move the desimal over till it looks like 1.00 count places moved left=negitive, right=positive
Step 1
Let the first consecutive integer be n
Then the second will be n+1
The third will be n+2
Step 2
Write an inequality for the problem
![n+n+1+n+2\leq15](https://tex.z-dn.net/?f=n%2Bn%2B1%2Bn%2B2%5Cleq15)
Step 3
Solve the inequality
![\begin{gathered} 3n+3\leq15 \\ 3n\leq15-3 \\ 3n\leq12 \\ \frac{3n}{3}\leq\frac{12}{3} \\ n\leq4 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%203n%2B3%5Cleq15%20%5C%5C%203n%5Cleq15-3%20%5C%5C%203n%5Cleq12%20%5C%5C%20%5Cfrac%7B3n%7D%7B3%7D%5Cleq%5Cfrac%7B12%7D%7B3%7D%20%5C%5C%20n%5Cleq4%20%5Cend%7Bgathered%7D)
Step 4
Find the possible set of three integers to satisfy the inequality.
![\begin{gathered} n=4---\text{ first integer} \\ n+1=4+1=5---\text{ second integer} \\ n+2=4+2=6---\text{ Third integer} \\ \text{check} \\ 4+5+6\leq15 \\ \text{Hence the set of thr}ee\text{ integers are; }\mleft\lbrace4,5,6\mright\rbrace \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20n%3D4---%5Ctext%7B%20first%20integer%7D%20%5C%5C%20n%2B1%3D4%2B1%3D5---%5Ctext%7B%20second%20integer%7D%20%5C%5C%20n%2B2%3D4%2B2%3D6---%5Ctext%7B%20Third%20integer%7D%20%5C%5C%20%5Ctext%7Bcheck%7D%20%5C%5C%204%2B5%2B6%5Cleq15%20%5C%5C%20%5Ctext%7BHence%20the%20set%20of%20thr%7Dee%5Ctext%7B%20integers%20are%3B%20%7D%5Cmleft%5Clbrace4%2C5%2C6%5Cmright%5Crbrace%20%5Cend%7Bgathered%7D)
One possible set of three integers that satisfy the inequality is;
{4,5,6}
The answer to the question “Round 0.423 to the nearest hundredth” is 0.42 because 3 is less than 5 and so 2 stays that way and so it is 0.42
Answer:
B. 18 sq in.
Step-by-step explanation:
Surface area of the triangular pyramid excluding the base = area of the three triangular faces = 3(½ × base × height)
Where,
base = 3 inches
height = ED = 4 inches
Plug in the known values into the equation
Surface area of the triangular pyramid excluding the base = 3(½ × 3 × 4)
= 3(3 × 2)
= 3(6)
= 18 sq in.
