Answer:
The area the sprinkler sprays with water is 201.06 square feet.
Step-by-step explanation:
Step 1; It is given that the diameter of the circular area of grass that the sprinkler sprays with water is 16 feet. The diameter of a circle is equal twice its radius. So we divide the diameter by 2 to get its radius.
Radius of the circle = Diameter of the circle / 2 = 16 feet / 2 = 8 feet.
Step 2; The area of any given circle is π times the square of the radius. The radius of this circle is equal to 8 feet.
Area of the circle = π × r² = 3.1415 × 8 feet = 201.06 square feet
Answer:
the second one
Step-by-step explanation:
10=43–|17p+12|
You won't use the absolute sign here. Since you cannot add variable to number AND there are no negatives.
10=43–|17p+12|
10=43–17p+12
Add 12 to 43.
10=43–17p+12
10=55-17p
Add 17p on both sides.
10=55-17p
17p+10=55
Subtract 10 from both sides.
17p+10=55
17p=45.
Therefore, the answer is p=2.64705882353.

Answer:
a. 0
Step-by-step explanation:
Which values from the set {0, 12, 2.5, 4} make the inequality 8g < 4 true?
Our inequality:
8g < 4
Substitute each values from the set {0, 12, 2.5, 4} for g, to find which value makes the inequality true.
For 0:
8g < 4
8(0) < 4
0 < 4
This statemen is true, because 0 is less than 4
For 12:
8g < 4
8(12) < 4
96 < 4
This statemen is false, because 96 is NOT less than 4
For 2.5:
8g < 4
8(2.5) < 4
20 < 4
This statemen is false, because 20 is NOT less than 4
For 4:
8g < 4
8(4) < 4
32 < 4
This statemen is false, because 32 is NOT less than 4
Hope this helps!
