The sides of a square field are 28 meters. A sprinkler in the center of the field sprays a circular area with a diameter that corresponds to a side of the field. How much of the field is not reached by the sprinkler? Round your answer to the nearest hundredth. Use 3.14 for π.
Answers
Answer:
168.24784 m²
Step-by-step explanation:
Area of the square:
28 x 28=784 sq. m.
Area of the circle:
π(r²)=π(14)²=196π
=615.75216
Area not covered by the sprinkler:
784-615.75216=168.24784 m²
Answer:
The sprinkler does not reach 168.56 m² of the field.
Step-by-step explanation:
Find the circular area sprayed by the sprinkler.
A = πr² Use the formula.
A = π(14)² Substitute. Use 14 for r.
A ≈ 3.14 × 14² Substitute. Use 3.14 for π.
A ≈ 3.14 × 196 Evaluate the power.
A ≈ 615.44 Multiply.
The area of the circular area is about 615.44 ft².
Find the area of the square field.
A = s² Use the formula.
A = 28² Substitute. Use 28 for s.
A = 784 Evaluate the power.
The area of the square field is 784 m².
Find how much of the field is not reached by the sprinkler. Subtract the circular area sprayed by the sprinkler from the area of the square field.
784 − 615.44 = 168.56

Which pair of triangles MUST be similar?
A. Triangle 5 has a 25 degree angle and a 75 degree angle. Triangle 6 has a 25 degree angle and a 70 degree angle.
B. Triangles 1 and 2 each have a 40 degree angle.
C. Triangle 7 has a 40 degree angle and a 35 degree angle. Triangle 8 has a 40 degree angle and a 105 degree angle.
D.Triangles 3 and 4 are both scalene. Each have a 65 degree angle.
Answers
Answer:
C
Step-by-step explanation:
The total measurement of a triangle is 180
Triangle 7 has a 40 degree angle and 35 degree angle.
40+35=75
180-75=105
Triangle 8 has the same angle that is 40 degrees and 105. And if you do the same math, you would get 35 for the missing angle of triangle 8
Can someone explain Slope to me? I literally have no idea what is from my teacher or from Aleks. I don't get what y1 and y2 are and i don't get what rise or run is. I have no idea how to get slope (brainliest for whoever explains a function too)
Answers
Yeah, I know Alex sucks. SO slope is the change in Y over x. So to find slope for ex. is lets use points (8,4) and (6,5) the equation to find slope is Y2-Y1 over X2-X1 or Y2-Y1 / X2-X1 and that basically the y's on the points you have. In this case it will be 4 and 5 since y always comes second or after the x. What I like to do is this X1(8), Y1(4) and X2(6), Y2(5). After you have that set up you just put them in the equation it will be 5-4/6-8 which is -1/2 use calculator. So Y is the y-axis and X is the x-axis.
Function is when every input(x) has only one output(y) . For example if we have the table
X,1 , 4 , 5, 9, 10 this is not a function because the -3 has both 9 and 10 for an output.
Y,2, 6 ,6, -3 , -3
A function will look more like this
1 2 3 4 5 6
2 4 6 8 10 12 every output has only one input
I recommend to watch Brian McLogan on youtu he can really help. Just search anything then his name. Or even Function then his name he explains it really well.

A 30ft electric line is suspended between the tops of two 20ft electric poles on level ground. The lowest point of the line is 5ft above the ground. What's the distance between the two electric poles?
Answers
Answer:
There is no distance between them
Step-by-step explanation:
For a 30 ft electric line to be placed between two 20ft electric poles, it would take 15 ft of the electric line to go down to about 5 ft above the ground and another 15 ft of the line to go to the top of the second electric pole. This means that a total of 30ft (15 ft + 15 ft) electric line would be needed which is all the cable we have.
For this to be possible then the poles must be adjacent to each other (i.e. no distance between them).
Use the graph below for this question: A 6 4 3 What is the average rate of change from x = -1 to x = -2? (1 point) 2 - 2 4 -1
Answers
Answer:
- 2
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
Here [ a, b ] = [ - 2, - 1 ] , then
f(b) = (f(- 1) = 5 ← corresponding value of y (- 1, 5 )
f(a) = f(- 2) = 7 ← corresponding value of y (- 2, 7 ) , thus
average rate of change = [tex]\frac{5-7}{-1-(-2)}[/tex] = [tex]\frac{-2}{1}[/tex] = - 2

I need help with this plz help me
Answers
Answer:
Please check the explanation.
Step-by-step explanation:
1) Writing the equation of the pattern
Figure 1 has 4 circles.
Figure 2 has 7 circles.
Figure 3 has 10 circles.
Thus, the sequence becomes
4, 7, 10,...
Finding the common difference between the adjacent terms
d = 7 - 4 = 3, d = 10 - 7 = 3
As the common difference is the same, so this represents the Arithmetic sequence.
so
d = 3
as
a₁ = 4
Thus, the nth term of the Arithmetic sequnce is
aₙ = a₁ + (n-1)d
aₙ = 4 + (n-1)3
aₙ = 4 + 3n - 3
aₙ = 1 + 3n
2) Determining the circles in the 23rd figure
As the nth term is given by
aₙ = 1 + 3n
putting n = 23
a₂₃ = 1 + 3(23)
a₂₃ = 1 + 69
a₂₃ = 70
3) Determining the figure having 82 circles
As the nth term is given by
aₙ = 1 + 3n
Given
aₙ = 82
To determine
n=?
Thus,
aₙ = 1 + 3n
82 = 1 + 3n
3n = 82-1
3n = 81
Dividing both sides by 3
n = 27
Therefore, 27th figure will have 82 circles.

Solving systems of equation using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
3x = y + 2
3x + 2y = 5
Step 2: Rewrite Systems
3x = y + 2
Subtract 2 on both sides: 3x - 2 = yRewrite: y = 3x - 2Step 3: Redefine Systems
y = 3x - 2
3x + 2y = 5
Step 4: Solve for x
Substitution
Substitute in y: 3x + 2(3x - 2) = 5Distribute 2: 3x + 6x - 4 = 5Combine like terms: 9x - 4 = 5Isolate x term: 9x = 9Isolate x: x = 1Step 5: Solve for y
Define equation: 3x + 2y = 5Substitute in x: 3(1) + 2y = 5Multiply: 3 + 2y = 5Isolate y term: 2y = 2Isolate y: y = 1A family has four daughters, Molly, Daisy, Rosie and Tilly.
