Answer:
D. both B and C
Step-by-step explanation:
The radius of the pond and border is (x+1). Then the diameter of the pond and border is 2(x+1) = 2x+2. The width of the square yard is 6 more, so is (2x +2) +6. = 2x +8.
The area of the yard is the square of the width: (2x +8)^2, and the area of the pond is pi times the square of its radius: π(x +1)^2.
The non-pond area of the yard is the difference of these:
non-pond area = (2x +8)^2 -π(x +1)^2
= (4x^2 +32x +64) -π(x^2 +2x +1) . . . . . . matches B
= (4 -π)x^2 +(32 -2π)x +(64 -π) . . . . . . . . matches C

Which graph shows the solution set of x2 + 9x + 20 / x2 - x -20 > 0 ?
Answers
Answer:
B Is correct
Step-by-step explanation:
Solve the solution set and divide to get the points and whether to fill them in or not.
-5 filled in, and 5 open circle
The graph of the solution set can be seen in option B.
What is a solution set?
The solution set is the set representing all solutions for an equation. It is also the roots that obey a quadratic equation or an inequality.
From the given equation, we have:
[tex]\mathbf{\dfrac{x^2+9x+20}{x^2-x-20}\ge 0}[/tex]
Let's factor out the quadratic equation, we have:
[tex]\mathbf{\dfrac{(x+4)(x+5)}{(x+4)(x-5)}\ge 0}[/tex]
By identifying the intervals;
x ≤ -5 or x > 5
The representation of these intervals on a graduated scale on a number line can be seen in the image attached below.
Therefore, we can conclude that the correct graph that show the solution set to the given equation can be seen in Option B.

a) 4.71ft
b) 3.53ft^2
Step-by-step explanation:
Perimeter is 1/2 the circumference
1/2 Circumference = 2*pi*radius
Radius = 1/2 Diameter
Radius = 3/2 = 1.5ft
Circumference = 2*pi*1.5ft = 9.42
1/2 Circumference = 4.71
4.71ft is the perimeter.
The area is 1/2 that of a full circle
A = pi*r^2
A = 3.14*1.5*1.5
A = 7.065ft^2
1/2 A = 3.53ft^2

what fraction of 7 2/5 is 49 1/3?
Answers
Answer:
8 1/6 / 1 7/8 = 196/45 = 4 16/45 ≅ 4.3555556
Step-by-step explanation:
Conversion a mixed number 8 1/6
to a improper fraction: 8 1/6 = 8 1/6 = 8 · 6 + 1/6= 48 + 1/6 = 49/6
To find new numerator:
a) Multiply the whole number 8 by the denominator 6. Whole number 8 equally 8 * 6/6 = 48/6
b) Add the answer from previous step 48 to the numerator 1. New numerator is 48 + 1 = 49
c) Write a previous answer (new numerator 49) over the denominator 6.
Eight and one sixth is forty-nine sixths
Conversion a mixed number 1 7/8
to a improper fraction: 1 7/8 = 1 7/8 = 1 · 8 + 7/8 = 8 + 7/8= 15/8
To find new numerator:
a) Multiply the whole number 1 by the denominator 8. Whole number 1 equally 1 * 8/8 = 8/8
b) Add the answer from previous step 8 to the numerator 7. New numerator is 8 + 7 = 15
c) Write a previous answer (new numerator 15) over the denominator 8.
One and seven eighths is fifteen eighths
Divide: 49/6 : 15/8 = 49/6 · 8/15 = 49 · 8/6 · 15 = 392/90 = 2 · 196 /2 · 45 = 196/45
Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 15/
8 is 8/15
) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the next intermediate step , cancel by a common factor of 2 gives 196/45
.
In words - forty-nine sixths divided by fifteen eighths = one hundred ninety-six forty-fifths.
My other dog, Beau, runs through the house dropping a line of slobber across
my 40 foot hallway. If he runs at a rate of 15 ftis, how long did it take him to mess
Answers
Answer:
2.67 seconds
Step-by-step explanation:
Distance covered by the dog = 40 ft
The rate at which the dog runs (speed) = 15 ft/s
But,
speed = [tex]\frac{distance}{time}[/tex]
So that,
time = [tex]\frac{distance}{speed}[/tex]
= [tex]\frac{40}{15}[/tex]
= 2[tex]\frac{2}{3}[/tex]
time = 2.6667 s
It would take the dog 2.67 s to mess.

Answer:B
Step-by-step explanation:I looked it up, I don’t copy people’s answers ok don’t flame me in comments.
The coordinates of X in triangle XYZ after reflection across the y axis is X' = (-4, -5)
TransformationTransformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, rotation and dilation
If a point A(x, y) is reflected over the line y axis, the new point is at A'(-x, y).
Triangle XYZ is reflected across the y-axis, and X = (4, –5). Hence X' = (-4, -5)
