Answer:

You first work out the radius, as below:

Area = pi x radius^2

=> radius = sqrt(Area/pi)

Then, you find out circumference C.

=> C = 2 x pi x radius

Hope this helps!

Write the coordinates of the vertices after a reflection over the x-axis. 1072
Liula [17]

The reflection about x-axis results in same x coodinate with oppositive of y coordinate. It can be expressed as,

(x,y)\rightarrow(x,-y)

Determine the coordinates of the vertices after reflection over the x-axis.

Q(6,-8)\rightarrow Q^{\prime}(6,8)R(7,-8)\rightarrow R^{\prime}(7,8)S(7,-5)\rightarrow Q^{\prime}(7,5)T(6,-5)\rightarrow T^{\prime}(6,5)

Answer:

<u>The correct answer is 58 1/2 feet. See below to understand the difference of both methods.</u>

Step-by-step explanation:

1. Let's review the information provided to us for solving the question using both methods:

Area of each student = 4 1/2 square feet

Number of students = 13

2. Let's use the first method to solve the question:

4 1/2 = 9/2 (Improper fraction because the numerator, 9 is bigger than the denominator, 2)

9/2 * 13 = 117/2

<u>117/2 = 58 1/2 square feet</u>

3. Let's use the second method to solve the question:

4 1/2 = 4 + 1/2 (Using addition to rewrite the fraction)

(4 + 1/2) * 13 = (4 * 13) + (1/2 * 13) (Distributive property of the multiplication)

(4 * 13) + (1/2 * 13) = 52 + 13/2 = 52 + 6 1/2

<u>52 + 6 1/2 = 58 1/2 square feet</u>

19. You roll two standard number cubes. What is the probability that the sum is odd, given than one of the number cubes shows a
In-s [12.5K]

6 numbers per cube

 if one is a 1, then the other one has to be a 2, 4 or 6 to be an odd sum

1+2=3, 1+4=5,1+6=7

 since there are 3 numbers you can get that would be a 3/6 ( reduce to 1/2) probability


so 1/2 probability

What is the slope of a line that passes (4, 10) and (1, 10)
SpyIntel [72]

Answer:

The slope of the a straight line is given by the ratio of the Rise to the Run

of the line. The rise between the given points is zero.

The slope of the line that passes through the points (4, 10) and (1, 10) is zero.

Step-by-step explanation:

The given points are; (4, 10) and (1, 10)

The slope of a line, m, is given by the following formula;

Where;

(x₁, y₁) = (4, 10) and (x₂. y₂) = (1, 10), we get;

The slope of the line that passes through the points (4, 10) and (1, 10) is 0.
