Answer:
12.5
Step-by-step explanation:
20+20=40
10 miles
Since then you have ten minutes you gotta divide 5 and you"l get 2.5
10+2.5=12.5
Answer:
i think the answer is no i used tge desmo graphing calculator and tht point wasnt on it
Use 12 to divide evenly among 3 sets. it will be 4 each set. 12 is negative, and you are dividing by a positive, so the answer will be negative (-4).
Answer:
The first three terms are -30, -27 and -24
Step-by-step explanation:
The formula for nth term of a arithmetic series is given by:
aₙ = a₁ + (n - 1)d
Substitute n = 16 in the given equation:
a₁₆ = a₁ + (16 - 1)d
Where aₙ = a₁₆ = 15. Substitute in the given equation
15 = a₁ + 15d ⇒ Equation (i)
Sum of arithmetic sequence is given by:
Sₙ = n(a₁ + aₙ) / 2
Substitute n = 16 in the above equation:
S₁₆ = 16(a₁ + a₁₆) / 2
Where S₁₆= -120 and a₁₆=15, substitute:
-120 = 16(a₁ + 15)/2
-240 = 16(a₁ +15)
-15 = a₁ + 15
a₁ = -30
Substitute it in Equation (i)
15 = a₁ + 15d
15 = -30 + 15d
15d = 15+30
d = 45/15
d = 3
So
a₁ = -30
a₂ = a₁ + (2-1)d
a₂ = -30 + 3
a₂ = -27
a₃ = a₁ + (3-1)d
a₃ = a₁ + 2d
a₃ = -30 + 2(3)
a₃ = -30 +6
a₃ = -24
Answer:
37% of the backyard will not be covered by the water from the sprinkler.
Step-by-step explanation:
The sprinkler is at the centre (0,0). It squirts in a circular motion. The other end of the radius is at (12,16).
First we will calculate the radius of the circle.
Area of the circle = πr^2
= 3.1416*(20)^2
= 3.1416*400
= 1256.64
Area of yard = 40 ft * 50 ft
= 2000
Percent covered by the water = 100*(area of circle/area of yard)
= 100*(1256.64/2000)
= 100*(0.628)
= 62.8%
= 63%
Area not covered by the water = 100 - 63
= 37%
