Good morning,
Answer:
Step-by-step explanation:
h = altitude
side = a
using Pythagorean theorem: in the right triangle:
h² = a² - (a/2)²
= a² - a²/4
= 3/4a²
= [(√3/2)×a]²
⇒ h = (√3/2)×a.

Answer:
Part 1) Is not a valid code
Part 2) The last digit should be 6 in order to make it a valid code
Step-by-step explanation:
we have
2-81273-05213-8
we know that
The last number is the check digit (8)
<em>Verify the UPC number</em>
step 1
Sum the digits in the odd positions, starting at the left
so
2+1+7+0+2+3=15
step 2
Multiply the answer in step 1 by 3
15(3)=45
step 3
Sum the numbers in the even positions, ignoring the last (12th) digit because that is the check digit that you are verifying
Do not multiply this number by 3.
8+2+3+5+1=19
step 4
Add the results from steps 2 and 3
45+19=64
step 5
Subtract the number in step 4 from the next higher multiple of 10. In this example, the next multiple of 10 after 64 is 70, so subtract 64 from 70:
70-64=6
This number is not equal to the check digit (8)
therefore
Is not a valid code
The last digit should be 6 in order to make it a valid code

To convert this fraction to a decimal, just divide the numerator (9) by the denominator (11): 9 ÷ 11 = 0.8181818181818182. So,
9/11 = 0.8181818181818182
Don't forget the invisble negative ones to distriute
do inside to outside
{n-1-1[n-1-1(n-1)]}
do inside
{n-1-1[n-1-n+1]}
simplify inner parenthasees
{n-1-1[n-n+1-1]}
{n-1-1[0]}
multply
{n-1-0}
add
n-1-0=n-1
it is n-1 simplified
Answer:
708
Step-by-step explanation:
In month 1 she will have 118 because 135-17. She will do this for 6 months so you would do 118 times 6.
