Answer:
She can buy 5 rolls of crepe paper with 2ft of paper left.
Step-by-step explanation:
If you multiply 12ft by 4 sides you will get 48ft so then 5 rolls of paper that is 10ft equals 50ft so you will have more than enough paper
17(k + 6) > 3(5k + 4)
17(k) + 17(6) > 3(5k) + 3(4)
17k + 102 > 15k + 12
- 17k - 15k
2k + 102 > 12
- 102 - 102
2k > -90
2 2
k > -45
Answer: 
Step-by-step explanation:
We know that:
Where "d" is distance, "r" is rate and "t" is time.
Solved for the time "t":
The first step is to convert the distance from miles to feet.
Since 
, we get:
Knowing that:
We can substitute values into in order to find the time in seconds:
Since:
The time in minutes is:
Answer:
5/4
Step-by-step explanation:
The constant of proportionality is the coefficient of x: 5/4.
Answer:yes, the lawn can be watered completely by 4 installed sprinklers.
Step-by-step explanation:
The lawn is rectangular and its area is 32 square yards. Sprinklers are to be installed and each sprinkler waters in a circle. The formula for determining the area of a circle is expressed as
Area = πr²
Where
r represents the radius of the circle.
π is a constant whose value is 3.14
If each sprinkler can completely water a circular area of lawn with a maximum radius of 2 yards., the the maximum area that can be watered by each sprinkler would be
Area = 3.14 × 2² = 12.56 yards²
If 4 sprinklers are completely installed, then the total area that they can water would be
12.56 × 4 = 50.24 yards²
Therefore, the lawn can be watered completely by 4 installed sprinklers.
