The ladder is placed 6 feet away from the wall
The formula you have to use is a2 + b2= c2
(I used x instead of c)
225+36=x2
Add them
261=x2
Now find square root
Square root of x2=x
Square root of 261= 6.15549...
x=6.15549
The ladder can reach x feet
Answer:
Step-by-step explanation:
2(x + 3) + 4x + 1 - Distribute
2x + 6 + 4x + 1 - Add like terms
6x + 7
If solving for x:
6x = -7
x = -7/6
Answer: Rachel's unit rate is less than Kevin's because 3.2 is greater than 2.8.
Step-by-step explanation:
Given: Rachel bought 12 rolls of packing tape and paid a total of $33.60.
Therefore, the unit rate of tape bought by Rachel =
Hence, the unit rate of tape bought by Rachel =$2.8
From the table , Kevin bought 2 rolls of packing tape and paid a total of $ 6.40.
The unit rate of tape bought by Kevin =
Hence, the unit rate of tape bought by Kevin = $3.2
Clearly, 3.2>2.8
Therefore, Rachel's unit rate is less than Kevin's because 3.2 is greater than 2.8.
Step one- find a perfect square as close as possible to the number
step 2-divide the number by the square root
step 3- calculate the average of your result of step 2 and the root
step 4
Use the result of step 3 to repeat steps 2 and 3 until you have a number that you think is accurate enough for you.
