HOw far away can a person live from a radio station and hear its broadcast if the signal covers a circular area of 40000 square miles?
Answer:
The radio station is at the center of a circle with an area of 40,000 square miles. The furthest point that you could hear the broadcast would be on the outer edge of the circle or at the end of the radius of the circle. The formula for the area of a circle is:
Area = π[tex]r^{2}[/tex]
So we take what we know and work the formula in reverse.
40,000 = πr²
40,000 / π = r²
12,732.4 = r²
√12,732.4 = √r²
112.84 = r
The radius of a circle with an area of 40,000 square miles is 112.84 miles. This is the furthest point that you would be able to hear the broad cast.

A singles tennis court measures (8x – 2) ft long and (3x – 3) ft wide.Which expression represents the area of the court?
Answer:
The expression that represents the area of the court is: [tex]24x^2 - 30x + 6[/tex]
Step-by-step explanation:
Area of a rectangle:
A rectangle has length l and width w. The area of a rectangle is:
[tex]A = lw[/tex]
A singles tennis court measures (8x – 2) ft long and (3x – 3) ft wide.
This means that [tex]l = 8x - 2, w = 3x - 3[/tex]
Which expression represents the area of the court?
The tennis court is rectangular, so
[tex]A = lw = (8x - 2)(3x - 3) = 24x^2 - 24x - 6x + 6 = 24x^2 - 30x + 6[/tex]
The expression that represents the area of the court is: [tex]24x^2 - 30x + 6[/tex]

Determine the solution to the system of equations graphed below and explain your reasoning in complete sentences.
Answer:
The solution to the system of equations is (0, -3) because that is where the two graphs intersect. It is the only solution since the equations intersect at that point only.
Step-by-step explanation:
We have the two equations:
[tex]f(x)=|x+1|-4\text{ and } g(x)=-2x-3[/tex]
Remember that graphically, the solution(s) of a system of equations is always where the graphs intersect.
We can see that the two graphs intersect at (0, -3).
So, g(0) = -3 and f(0) = -3 also.
And that is the only point of intersection. So the only solution to our system here is (0, -3).

The Reyes want grilled chicken and tilapia for dinner. Mrs.
Reyes finds that chicken sells at Php 150 per kilogram and
tilapia sells at Php 100 per kilogram. How many kilograms of
each she buy if the total cost is not to exceed to Php 450?
Answer:
Kilogram of chicken = 1
Kilogram of tilapia = 3
Step-by-step explanation:
Cost of chicken = 150 per kilo
Cost of tilapia = 100 per kilo
Number of kilos of each if total cost should not exceed 450
Let :
Number of kilo of chicken = x
Number of tilapia kilo = y
The constraint :
150x + 100y ≤ 450
We could choose some reasonable values of x and y then, test the constraint ;
If x = 1 and y = 3
150(1) + 100(3) = 450
Hence,
1 kilo of chicken with 3 kilos of tilapia offers the greatest combination of Number of kilograms of tilapia and chicken that could be purchased and still satisfy the maximum cost constraint.

Point P has coordinates (1, 3). Point Q has coordinates (4, 8). How long is the line segment? Round to the nearest tenth if necessary.
Answer:
The length of the line segment is of 5.9 units.
Step-by-step explanation:
Distance between two points:
Suppose that we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between these two points is given by:
[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
How long is the line segment?
The distance between points P and Q. So
P(1,3), and Q(4,8).
[tex]D = \sqrt{(4-1)^2+(8-3)^2} = \sqrt{3^2 + 5^2} = \sqrt{34} = 5.9[/tex]
The length of the line segment is of 5.9 units.

Step-by-step explanation:

The value of the acceleration due to gravity is 9.8 m/s^2.
What is the acceleration due to gravity?Now we know that the acceleration due to gravity is the slope when you plot the graph of velocity against time for motion under gravity.
Now we must look at the data given and use;
v = u + at
Given that the object was dropped, u = 0 hence
v = at
at t = 1 s and v = 9.8 m/s
a = 9.8 m/s/ 1 s
a = 9.8 m/s^2
This value remains the same irrespective of the time that you pick hence it is the value of the acceleration due to gravity.

What type of triangle is triangle ABC?
Give your reasons for your answer:
Answer:
a. Isosceles
b. It has two equal angles
Step-by-step explanation:
✅<DCA = <BAC = 50° (alternate interior angles are congruent)
<ACB = 180 - (<BAC + <ABC) (sum of triangle)
<ACB = 180° - (50° + 80°) (substitution)
<ACB = 50°
✅∆ABC is an isosceles triangle judging from the measure of its three angles. ∆ABC has two equal angles. ∆ABC is therefore an isosceles ∆.

There are 9 marbles representing 3 different colors. Write a problem where 2 marbles are selected at random without replacement and the probability is 16.
Answer fast pls! <3 xx
Answer:
There are 9 marbles in the bag. We pick 2 without replacement and get a probability of 1/6.
Each draw of a marble has a probability associated with it. Multiplying these gives 1/6 so let us assume the probabilities are (1/3) and (1/2).
In order for the first draw to have a probability of 1/3 we need to draw a color that has (1/3)(9)=3 marbles. So let's say there are 3 red marbles. The P(a red marble is drawn) = 1/3.
Now that a marble has been drawn there are 8 marbles left. In order for the second draw to have a probability of 1/2 we must draw a color that has (1/2)(8) = 4 marbles. So let's say there are 4 blue marbles out of the 8.
Since there are 9 marbles to start and we have 3 red marbles and 4 blue marbles, the remaining 2 marbles must be a different color. Let us say they are green.
The problem is: There are 3 red marbles, 4 blue marbles and 2 green marbles in a jar. A marble is picked at random, it's color is noted and the marble is not replaced. A second marble is drawn at random and its color noted. What is the probability that the first marble is red and the second blue?
