The approximate circumference of the path Round to the nearest hundredth is 93.12 feet.
What is circumference of circle?A circle's outside boundary is called the circumference and can be measured, or calculated, by using
Circumference = 2πr
where r is the radius of circle.
Now it is given that,
circumference of pond = 68 feet
⇒ 2πr = 68
⇒ r = 34/π
⇒ r = 10.82 feet
Now it is also given that, The outer edge of the path is going to be 4 feet from the pond all the way around
⇒ Radius of path, R = r + 4
⇒ Radius of path, R = 10.82 + 4
⇒ R = 14.828
So,circumference of the path = 2πR
⇒ circumference of the path = 2π*14.828 = 93.119 feet
⇒ circumference of the path Round to the nearest hundredth = 93.12 feet
Thus, the approximate circumference of the path Round to the nearest hundredth is 93.12 feet.

Write an equation for each line. m=-5 and the y -intercept is (0,-7) .
The equation of the line for given values is y = -5x - 7.
Given a point and a slope, how do you build an equation for a line?When you know the slope of the line to be investigated and the provided point is also the y intercept, you may utilize the slope intercept formula, y = mx + b. (0, b). The y value of the y intercept point is denoted by the symbol b in the formula.
The standard equation of straight line is y = mx + c.

Your friend says the line y=-2 x+3 is perpendicular to the line x+2 y=8 . Do you agree? Explain.
I do not agree that the line y = -2x + 3 is perpendicular to the line x + 2y = 8.
Perpendicular lines are lines that form right angles at the point of intersection. The equation of the lines that are in perpendicular with each other have slopes that are negative reciprocal with one another.
If slope of A = a/b, and B is perpendicular to A, then slope of B = -b/a.
To check if the two given equation of the line is perpendicular with each other, get their slopes and see if they're negative reciprocal of one another.
Line 1 : y = -2x + 3
m = -2
slope of perpendicular line to line 1 = 1/2
Line 2 : x + 2y = 8 ⇒ 2y = -x + 8 ⇒ y = -1/2 x + 4
m = -1/2
1/2 ≠ -1/2
Since the negative reciprocal of the slope of the first line is not equal to the slope of the second line, then they are not perpendicular with each other.

Find point X on AB such that the ratio of AX to XB is 1:3
The point X on AB such that the ratio is 1.25 units.
XB=AX×3
AX+XB=AB
AX+(AX×3)=AB
AX×4=AB
AX×4=9
AX=2.25
X=-1+2.25
X=1.25 units
Ratio shows how often one number is contained in another. For instance, the proportion of oranges to lemons in a bowl of fruit is eight to six if there are eight oranges and six lemons (that is, 8:6, which is equivalent to the ratio 4:3). The proportions of oranges to the overall amount of fruit are 8:14 for oranges and 6:8 (or 3:4) for lemons (or 4:7).
The quantities in a ratio can be of any form, including counts of people or things, measures of lengths, weights, or times, etc.
Hence , the Coordinate in units: (2,1.25). In most contexts, both numbers are restricted to be positive.

[tex]\frac{12}{5}[/tex] = [tex]2\frac{2}{5}[/tex] revolutions per second is the unit rate.
What is unit rate ?An item's unit rate is its price for one of it. This is expressed as a ratio with a one as the denominator. For instance, if you covered 70 yards in 10 seconds, you covered 7 yards on average every second. Seven yards in one second and 70 yards in ten seconds are both ratios, but only one of them is a unit rate.
1) Convert mixed fractions into fractions.
[tex]6\frac{2}{5}[/tex] = [tex]\frac{((6*5) + 2)}{5}[/tex] = [tex]\frac{32}{5}[/tex]
[tex]2\frac{2}{3}[/tex] = [tex]\frac{((2*3) + 2)}{3}[/tex] = [tex]\frac{8}{3}[/tex]
2) [tex]\frac{32}{5}[/tex] ÷ [tex]\frac{8}{3}[/tex] ; where [tex]\frac{32}{5}[/tex] is the 1st fraction and [tex]\frac{8}{3}[/tex] is the 2nd fraction
a) Find the second fraction's reciprocal:
From [tex]\frac{8}{3}[/tex] to [tex]\frac{3}{8}[/tex]
b) Multiply the first fraction by the second fraction's reciprocal, which is 32/5, 5/3, or (5/3), to get 96/40.
c) Simplify the fraction.
Divide 96 / 40 by 4 to get 24/10.
Divide 24/10 by 2, and the result is 12/5. The 96/40 simple fraction

Solve each equation. Check your answers. -3(x-4)=2(x+8)
The solution of the given equation -3(x-4)=2(x+8) is at x = -4/5.
According to the given question.
We have a linear equation in one variable.
-3(x-4)=2(x+8).
As we know that,the linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.
Thereofre, the solution of the given equation is given by
-3(x - 4) = 2(x + 8)
⇒ -3x + 12 = 2x + 16
⇒ -3x - 2x = 16 - 12
⇒ -5x = 4
⇒ x = -4/5
We get the solution of the given equation is at x = -4/5.
Now, we can check that x = -4/5 is a solution of the given equation or not.
Therefore,
L.H.S
= -3(-4/5 - 4)
= 12/5 + 12
= (12 + 60)/5
= 72/5
Similarly,
R.H.S
= 2(-4/5 + 8)
= -8/5 + 16
= -8 + 80/5
= 72/5
So, L.H.S = R.H.S
Hence, the solution of the given equation -3(x-4)=2(x+8) is at x = -4/5.

The probability that it hits region I is 15%.
Probability:
Probability means the possibility of the required event.
The formula for the probability is written as,
P(E) = n(E)/n(S)
Where,
P(E) is the probability of an required event
n(E) is the number of possible outcomes
n(S) is the total number of events.
Given,
At a carnival, the object of a game is to throw a dart at the board and hit region III.
Here we need to find the probability that it hits region I.
Consider the board was look like the following figure.
Then based on the given figure,
First, we have to find the total area of the board and the area of the required region.
And then we have to compare it to calculate the Probability.
So, the total area of the board is,
=> total area of the board = (10 + 30)(10 + 15)
=> total area of the board = 1000 in²
Now, the The area of the region I is
=> Area = (10)(15)
=> Area = 150 in²
Therefore, the probability that it hits region I is
=> P = 150/1000
=> P = 15/100
=> P = 15%
Therefore, the probability that it hits region I is 15%.

Find the value of c that completes the square. r^2+21r+c
Answer:

Step-by-step explanation:
Hello!
Perfect Square Trinomial: [tex](a + b)^2 = a^2 + 2ab + b^2[/tex]
21r is basically 2 times r and b, the missing number.
Solve for b21r = 2*r*b10.5 = bThe missing number, b, would be 10.5
Now c is basically b², so we just have to simplify 10.5²:
10.5²110.25c should be 110.25 for it to be a Perfect Square Trinomial. The factored form would be (r + 10.5)².
Evaluate the expression for the given values of the variables.
11(a+2b)+2(a-2b);a=-3 and b=4
The value of expression is 33
For evaluating the expression, we will keep the given values of variables in the expression. Further solving will be done according to the mathematical operators.
Rewriting the equation -
Value = 11 (a + 2b) + 2 (a - 2b)
Now keeping the values of variables in expression -
Value = 11 (-3 + 2×4) + 2 (-3 - 2×4)
Firstly solving the brackets
Value = 11 ( -3 + 8) + 2 (-3 - 8)
Value = 11 (5) + 2 (-11)
