Step-by-step explanation:
There are infinite solutions.
By observing the inequality, we can tell that the unknown number, n, is greater than the number 4.
Answer:
√
42 lies between 6 and 7
Step-by-step explanation:
We know that √
42 will lie between √
36 and √
49
And √
36
=
6 ; √
49
=
7
Hence we can be sure that √
42 lies between 6 and 7
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.
Answer:
19
Step-by-step explanation:
From the question we have been given this data
y=ax+b
a=−1.077
b=30.98
r2=0.744769
r=−0.863
Where
X = number of situps
Y = number of hours spent watching tv
We have x = 11
Inputting this into the formula we have
Y = (-1.077)(11) + 30.98
Y = −11.847 + 30.98
Y = 19.133
Which is approximately 19
Therefore we conclude that a person who watches TV for 11 hours can do 19 situps.
