The circumference of a circular lawn is 110 feet. If you double the radius, what will the new circumference be?
Answer:
220
Step-by-step explanation:
The new circumference of the circle will be 220 feet if the circumference of a circular lawn is 110 feet.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
We have:
The circumference of a circular lawn is 110 feet.
2πr = 110
r = 55/π
Double the radius:
R = 2r= 110/π
New circumference = 2πR = 2π(110/π) = 220 feet
Thus, the new circumference of the circle will be 220 feet if the circumference of a circular lawn is 110 feet.

Determine the solution for the equation, 5w - 9= 44.
Answer:
w=2
Step-by-step explanation:
Simplifying
4w + -9(6 + -5w) = 44
4w + (6 * -9 + -5w * -9) = 44
4w + (-54 + 45w) = 44
Reorder the terms:
-54 + 4w + 45w = 44
Combine like terms: 4w + 45w = 49w
-54 + 49w = 44
Solving
-54 + 49w = 44
Solving for variable 'w'.
Move all terms containing w to the left, all other terms to the right.
Add '54' to each side of the equation.
-54 + 54 + 49w = 44 + 54
Combine like terms: -54 + 54 = 0
0 + 49w = 44 + 54
49w = 44 + 54
Combine like terms: 44 + 54 = 98
49w = 98
Divide each side by '49'.
w = 2
Simplifying
w = 2
Answer:
w has multiple forms
exact w = 53/5
decimal w = 10.6
mixed number w = 10 3/5
5 x 53/5 - 9 = 44
Jan and two of her friends raised money by having a bake sale. They split the proceeds. If each person received $32.19, how much money did the girls earn in total at their bake sale? Write an equation and solve it to find the answer.
Answer: 1. Equation =3x = M , where x = money each received and M= total money received.
2.total money from bake sale=$96.57
Step-by-step explanation:
STEP 1
Let the total money receive from proceeds be = M
and let the amount of money each receive after the split = x
Since Jan and her two friends raised the money together, the total proceeds will be calculated using the equation
x+x+x= M
3 x = M ---- Equation
STEP 2--- Solving
if 3 x= M
and x =mount of money each receive after the split=$32.19
Therefore total money from bake sale, M = 3x = 3 x 32.19 = $96.57
Answer:
The last one
Step-by-step explanation:
$96.57

Remark
The best way to find the slope is to take the two points that are marked.
(5,3) and (0,-1)
Formula
m = (y2 - y1)/(x2 - x1)
Givens
y2 = 3
y1 = -1
x2 = 5
x1 = 0
Solution
m = (3 - -1)/(5 - 0)
m = (3+1) / 5 = 4/5
the line parallel to the line in the graph would be the new with a slope equal to the given line.
The perpendicular to this line would have a slope of
m * m1 = -1
4/5 * m1 = - 1 Multiply by 5
4 * m = -5 Divide by 4
m = -5/4
A line perpendicular to the given line would have a slope of -5/4
Find the volume for 2 different spheres by randomly choosing different radii.
Using the same radii values, find the volume of 2 cylinders where the height of the cylinder is the same as the diameter of the sphere.
Answer:
The volume of a sphere of radius r is:
S = (4/3)*pi*r^3
The volume of a cylinder of radius r and height h is:
C = pi*r^2*h
For this problem the height of the cylinders will be equal to the diameter of the spheres, which is equal to two times the radius.
First, let's use the radius: r = 2.
The volume of the sphere will be:
S = (4/3)*3.14*(2)^3 = 33.49
The volume of the cylinder, where h = 2*2 = 4, is:
C = 3.14*(2^2)*4 = 50.24
Now, let's choose the radius r = 3.
The volume of the sphere will be:
S = (4/3)*3.14*3^3 = 113.04
The volume of a cylinder with this radius and h = 3*2 = 6, is:
C = 3.14*(3^2)*6 = 169.56

What is an equation of the line that passes through the point (-2, 2) and is parallel to the line 2x + y = 1?
An equation of the line that passes through the point (-2, 2) and is parallel to the line 2x+y=1 is y=2x+6.
Given that, the equation of a line is 2x+y=1 and the coordinate point is (-2, 2).
What is an equation of the line?The equation of line is an algebraic form of representing the set of points, which together form a line in a coordinate system. The numerous points which together form a line in the coordinate axis are represented as a set of variables x, y to form an algebraic equation, which is referred to as an equation of a line.
In the equation of a line 2x+y=1, slope is 2.
As we know the slopes of parallel lines are equal, that is m1=m2.
Now, put (-2, 2) and m=2 in y-y1=m(x-x1) and simplify.
That is, y-2=2(x+2)
⇒ y-2=2x+4
⇒ y=2x+4+2
⇒ y=2x+6
Therefore, an equation of the line that passes through the point (-2, 2) and is parallel to the line 2x+y=1 is y=2x+6.

If an plane can fly around the earth at the equator without stopping. It would have traveled about 24,900 miles. Find the radius of the earth.
Step-by-step explanation:
This equation gives circumference (24900 miles). Knowing this the formula to start off finding radius is
[tex]c=2\pi r[/tex]
we know c(circumference) and we know pi(3.1415926535...)
so move the numbers to isolate r(radius) to look something like this
[tex]\frac{c}{2\pi } =r[/tex]
input the known values then solve.
[tex]\frac{24900}{2\pi } =r[/tex]
[tex]\frac{12450}{\pi } =r[/tex]
[tex]3962.95808... =r[/tex]

Review the following information about vectors q and r.
What is the value of a?
q=(-4,1)
31
r = (a, 3)
7(q + r) = (-35, 28)
-5
==========================================
Work Shown:
q = (-4, 1) is one vector
r = (a,3) is another vector
The resultant vector is
q+r = (-4,1)+(a,3)
q+r = (-4+a,1+3)
q+r = (-4+a,4)
Multiply both sides by 7
7(q+r) = 7*(-4+a,4)
7(q+r) = (7*(-4+a),7*4)
7(q+r) = (-28+7a, 28)
---------------
Since 7(q+r) = (-35, 28), we know that,
(-28+7a, 28) = (-35, 28)
which leads to
-28 + 7a = -35
when we equate the x components of each vector. Let's solve for 'a'
-28 + 7a = -35
7a = -35+28
7a = -7
a = -7/7
a = -1
--------------
Check:
q = (-4,1)
r = (a,3) = (-1,3)
q+r = (-4,1)+(-1,3)
q+r = (-4+(-1), 1+3)
q+r = (-5, 4)
7*(q+r) = 7*(-5, 4)
7*(q+r) = (7*(-5), 7*4)
7*(q+r) = (-35, 28)
The answer is confirmed.

Kathy is 33 years old. She is 7 years younger than 5 times her daughter's age. The equation,
5x-7= 33, where x equals her daughter's age, can be used to find the age of Kathy's daughter. How
old is Kathy's daughter?
Answer:
Kathy's daughter is 8 years old
Step-by-step explanation:
What we know:
Kathy is 33 years old.
That is 7 years younger than 5 times her daughter's age.
With that, the equation 5x - 7 = 33 can be used to find x.
Step 1:
Move "- 7" to the right side of the equation, and find the opposite of it.
5x = 33 + 7
Step 2:
Add "33" and "+7" to get "40."
5x = 40
Step 3:
Divide both side by "5."
5x/5 = 40/5
x = 8
Thus, Kathy's daughter is 8 years old.

8
