Answer:
398.12 m
Step-by-step explanation:
The perimeter fence consists of two half-circles (hence, a full circle) of radius 36.5 m, and two straight lengths of 84.39 m.
The circumference of a circle is given by the formula ...
C = 2πr
so the circular sections of fence have a total length of ...
C = 2π(36.5 m) = 73π m ≈ 229.34 m
__
Adding the two straight lengths to this gives a total perimeter of ...
P = 2(84.39 m) +229.34 m = 398.12 m
The approximate length of the fence around the field shown is 398.12 m.
_____
Comment on significant figures
Since the length of the straight section is given to the nearest cm, we have elected to give the total length accurate to the nearest cm. If we assume that the radius is only good to 3 significant figures, then the circumference of the circle is good only to 3 significant figures (229 m). Thus, we must give our approximate value to the same precision, the nearest meter: 398 m.

Y=1/3x + ? DUE IN 2 MINS PLEASE HELP
Answer: Using the slope-intercept form, the y-intercept is 0 .
Step-by-step explanation:
'm so sorry :( i dont know if this right tho
Answer:
y = 3x + 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 3, 4) and (x₂, y₂ ) = (3, 2) ← 2 points on the line
m = [tex]\frac{2-4}{3+3}[/tex] = [tex]\frac{-2}{6}[/tex] = - [tex]\frac{1}{3}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{1}{3} }[/tex] = 3, thus
y = 3x + c ← is the partial equation
To find c substitute (- 1, 4) into the partial equation
4 = - 3 + c ⇒ c = 4 + 3 = 7
y = 3x + 7 ← equation of perpendicular line

Trigonometric Ratios
The ratios of the sides of a right triangle are called trigonometric ratios. The longest side of a right triangle is called the hypotenuse and the other two sides are the legs.
The tangent ratio relates the opposite leg with the adjacent leg. Please note the given side is the opposite leg to 60° and x is the adjacent leg to 60°, thus we apply the tangent ratio:
[tex]\displaystyle \tan\theta=\frac{\text{opposite leg}}{\text{adjacent leg}}[/tex]
[tex]\displaystyle \tan 60^\circ=\frac{3\sqrt{3}}{x}[/tex]
Solving for x:
[tex]\displaystyle x=\frac{3\sqrt{3}}{\tan 60^\circ}[/tex]
Since:
[tex]\tan 60^\circ=\sqrt{3}:[/tex]
[tex]\displaystyle x=\frac{3\sqrt{3}}{\sqrt{3}}[/tex]
Simplifying:
x = 3

What are the rate of change and the initial value of the function represented by the graph?
The rate of change is 3 and the initial value is 5.
The rate of change is 13 and the initial value is 5.
The rate of change is 5 and the initial value is 3.
The rate of change is 5 and the initial value is 13.
Answer:
The rate of change is 1/3 and the initial value is 5.
Step-by-step explanation:
See attachment for graph
First, we select any two corresponding x and y values
[tex](x_1,y_1) = (0,5)[/tex]
[tex](x_2,y_2) = (9,8)[/tex]
This implies the slope and slope (m) is calculated as follows:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{8-5}{9-0}[/tex]
[tex]m = \frac{3}{9}[/tex]
Simplify
[tex]m = \frac{1}{3}[/tex]
(b) Calculating the initial value.
This is the point [tex]where\ x = 0[/tex]
From the graph, we have the following point:
[tex](x_1,y_1) = (0,5)[/tex]
Here, we have that:
[tex]x = 0[/tex] and [tex]y = 5[/tex]
This means the the initial value is 5

-3(x - 3) + 2 = -22
solve for x
Answer:
x=11
Step-by-step explanation:
Answer:
x would be 11
Step-by-step explanation:
Let's solve your equation step-by-step.
−3(x−3)+2=−22
Step 1: Simplify both sides of the equation.
−3(x−3)+2=−22
(−3)(x)+(−3)(−3)+2=−22(Distribute)
−3x+9+2=−22
(−3x)+(9+2)=−22(Combine Like Terms)
−3x+11=−22
−3x+11=−22
Step 2: Subtract 11 from both sides.
−3x+11−11=−22−11
−3x=−33
Step 3: Divide both sides by -3.
−3x/-3=-33/-3
x=11
5x - 22 = -7

12. Which area best describes a continental slope?
area of land dropping steeply towards deep ocean basins
75-mile shallow flat area just off coastlines
thick deposits of sediments carried out from land
the surf area along coastlines
Answer:
area of land dropping steeply towards deep ocean basins :)
Step-by-step explanation:
"Area of land dropping steeply towards deep ocean basins" best describes a continental slope. Option A is correct.
What is a continental slope?The continental slope is defined as "the overall reduction in steepness out from the shelf margin to the top limit of the continental rise."
The geological boundary of the continent is where it ends and the ocean's deepest floor begins. The ocean bottom dips downhill when the continental shelf terminates, increasing the depth of the water.
The continental slope is the location where the continent ends and the ocean bottom begins.
Thus, the area of land dropping steeply towards deep ocean basins" best describes a continental slope. Option A is correct.

A school has 617 students. Each class has between 28 and 32 students. Which is the best estimate of the number of classes in the school?
14 classes
20 classes
30 classes
60 classes
Answer:
20
Step-by-step explanation:
617/28= 22 (rounded too)
617/32= 19 ( rounded too)
19-22 is teh amount of classes that can be filled with 28 to 32 students.
20 is correct because it is around the amount of classes that there can be. !4 is too little so the number of students should be smaller.
30 and 60 classes are to big. there would only be about 10 or 20 kids per class

Answer:
Yes for 1st and 4th, No for the 2nd, 3rd and 5th.
Step-by-step explanation:
You need to plug the first number in each set of brackets into x and the second number into y. The first equation asks if y is the greater than -x. The only ones this is true for are the 1st, 3rd, and 4th answers, so the 2nd and 5th are no. Now check the 1st, 3rd and 4th to see if the answer is less than or equal to 2 when plugging in x and y. This is true for the 1st and 4th answers, so move those to yes and the 3rd to no.
Answer: Yes for 1st and 4th, No for the 2nd, 3rd and 5th.

-3x + 4/5 = -2/3x + 12
Answer:
Step-by-step explanation:
You first collect isolate all the variables
-3x+4/5=-2/3x+12
Subtract 4/5 from both side and add2/3x from both sides
-7/3x=56/5
You then multiply both sides by the reciprocal of the coefficient of the variable, in this case -3/7
-7/3x*(-3/7)=(56/5)*(-3/7)
x=-168/35
x=-24/5
