=========================================================
Explanation:
We'll use Heron's Formula.
When given the three sides a,b,c, the area of the triangle is
[tex]A = \sqrt{s(s-a)(s-b)(s-c)}[/tex]
where s = (a+b+c)/2 is the semi-perimeter, aka half the perimeter.
Let's compute the value of s first
s = (a+b+c)/2 = (8+9+3)/2 = 20/2 = 10
Then we can say,
[tex]A = \sqrt{s(s-a)(s-b)(s-c)}\\\\A = \sqrt{10(10-8)(10-9)(10-3)}\\\\A = \sqrt{140}\\\\A \approx 11.8321595661992\\\\A \approx 11.83\\\\[/tex]
The triangle has area of roughly 11.83 square meters.

Sylvia has 6 1/2 boxes of chocolate to share at a family picnic. If she gives each person 1/3 of a box, how many people can receive chocolate?
The number of persons that would be able to receive the chocolates based on the question is 19
How to solve for the numberThe total number of chocolate = 6 1/2
This can be written to be 13 / 2 or 6.5
The number or amount that she has to give from what is contained in the box to each person is 1/3 = 0.33
Hence to get the number of people that would receive the chocolate we would have
6.5 / 0.33
= 19.5
This can be approximated to 19
Hence the total number that would receive the chocolate is 19

Answer:
4, 0, 3
Step-by-step explanation:
You want to know which numbers are possible values of m, given a graph of the values of m.
Interpreting a number line graphThe graph shows an empty circle at m=6, and an arrow extending to the left from that point. The empty circle means that m=6 is not a possible value of m.
The arrow extends through possible values of m, and extends to negative infinity. That means m may have any value less than 6. Such values on the offered list are ...
4, 0, 3
__
Additional comment
The values 6, 7, 9 are not covered by the dot or the arrow, so are not possible values of m.
Answer:
0, 3, 4
Step-by-step explanation:
When the circle is open and pointing to the left, it means that the variable is less than the number the circle is at. In this case, it means that the variable is less than 6, so you would select all values that are less than 6!

How do I graph y+4=5x?
To graph a linear equation, including the function y + 4 = 5 · x, we needed to rewrite the equation into its explicit form, mark two distinct points on a Cartesian plane and pass a line through them. The result is presented in the image attached below.
How to graph a linear equationHerein we find a linear equation in a non-canonical form and to which we are asked to graph. According to geometry, lines can be created by knowing the location of two distinct points on Cartesian plane. The detailed procedure is now shown.
First, clear the variable y to obtain the explicit form of the linear equation:
y = 5 · x + 4
Second, look up for two distinct points on Cartesian plane by evaluating the expression at distinct values of x:
x = 0
y = 5 · 0 + 4
y = 4
x = 1
y = 5 · 1 + 4
y = 9
The points (0, 4) and (1, 9) lie on the line.
Third, mark the coordinates of the two points and pass a line through them.

A cooler contains eleven bottles of sports drinks: three lemon-lime flavored, five orange-flavored, and three fruit-punch flavored. You randomly grab a bottle. It is a lemon-lime or a fruit punch..
The probability of grabbing a lemon-limbed or a fruit punch bottle from the cooler is 6/11.
What is 'AND' and 'OR' statements in probability?'AND' represents multiplication and 'OR' represents addition.
The total number of bottles of sports drinks which is also our sample space
N(S) = 11.
The number of lemon-lime flavored bottles [tex]N(L_l)[/tex] = 3.
The Number of fruit punch flavored bottles [tex]N(F_p)[/tex] = 3.
So, the probability of grabbing a lemon-lime bottle [tex]P(L_l)[/tex] = [tex]\frac{N(L_l)}{N(S)}[/tex] = 3/11.
And, the probability of grabbing a fruit punch bottle [tex]P(F_p)[/tex] = [tex]\frac{N(F_p)}{N(S)}[/tex] = 3/11.
∴ The probability of grabbing a lemon-lime or a fruit punch bottle is the sum of the probability [tex]P(L_l) + P(F_p)[/tex].
= 3/11 + 3/11.

x and y graph also known as the x and y-axis are two important lines that make a graph. A graph consists of a horizontal axis and a vertical axis where data can be represented. A point can be described in a horizontal way or a vertical way, which can be easily understood using a graph. These horizontal and vertical lines or axis in a graph are the x-axis and y-axis respectively.
A x and y graph can be defined by the two axes i.e. x-axis and the y-axis that form a coordinate plane for a graph. The horizontal axis is represented by the x-axis and the vertical axis is represented by the y-axis. The point where the x and y-axis intersect is known as the origin and is used as the reference point for the plane.
y = 1/3x

Tavon have a gift card for $130 that loses three dollars for each 30 day It is not used he another gift card for $110 that loses 2.5 for each 30 day. It’s not used write and solve an equation for the number of 30 days periods Until the value of kid cards will be equal what will the value of each card Be when they have equal value
The equation for the number of 30 days periods until the value of both cards will be equal is 130 - 3x = 110 - 2.5x
Equationlet
Number of 30 days period = x
Gift card 1:
130 - 3x
Gift card 2:
110 - 2.5x
Equate both gift cards130 - 3x = 110 - 2.5x
130 - 110 = -2.5x + 3x
20 = 0.5x
divide both sides by 0.5x = 20/0.5
x = 40
So,
Gift card 1:
130 - 3x
= 130 - 3(40)
= 130 - 120
= $10
Gift card 2:
110 - 2.5x
= 110 - 2.5(40)
= 110 - 100
= $10
Therefore, the value of each card when they have equal value is $10

A skier is trying to decide whether or not to buy a season ski pass. A daily pass costs $79. A season ski pass costs $350. The skier would have to rent skis with either pass for $30per day. How many days would the skier have to go skiing in order to make the season pass less expensive than the daily passes?
Answer:
Let s =cost of skiing per day. Here's what we know:
450 + 20s = 64s + 20s (the season pass plus ski rentals equates to daily skiing plus ski rentals)
We have 20s on both sides, so those cancel out easily:
450 = 64s
Divide both sides by 64:
7.03 ≈ s
You can't pay for a partial day, so the skier will have to ski for at least 8 days to make the season pass cheaper than getting daily passes.

What will be the median of the following set of numbers? 126,132,128,124,134,142,134,146,134,132
Answer:
133
Step-by-step explanation:
for that we need to sort the numbers :
124,126,128,132,132,134,134,134,142,146
the median is the number, for which half of the other numbers are smaller, and the other half of the other numbers is larger.
as we have 10 numbers, there is no such single middle number.
instead, we take the 2 middle numbers and calculate their mean value. that is then the median.
the 2 middle numbers are based on our sorted list above
132, 134
the mean value is
(132 + 134)/2 = 133
and that is then the median.
abc is right angled triangle at a then cosine angle b sine angle c equals
abc is right angled triangle,
A triangle in which one of the interior angles is 90° is called a right angled triangle.
The longest side of a right triangle, which is also the side opposite the right angle, is the hypotenuse.The two arms of the right angle triangle are the height and the base.According to the diagram 'ab' is the height or perpendicular 'ac' is the base and 'bc' is the hypotenuse of the triangle.
Sin θ = [tex]\frac{perpendicular}{hypotenuse}[/tex]
Cos θ = [tex]\frac{base}{hypotenuse}[/tex]
Tan θ = [tex]\frac{perpendicular}{base}[/tex]
Cosine angle at b will be represented as Cos b = [tex]\frac{base}{hypotenuse}[/tex] = [tex]\frac{ab}{bc}[/tex]
the base considered for the angle at 'b' will be 'ab' since Cosine uses the base attached to the angle.
Sine angle at c will be represented as Sin c = [tex]\frac{perpendicular}{hypotenuse}[/tex] = [tex]\frac{ab}{bc}[/tex]
the perpendicular considered for the angle at 'c' will be 'ab' since Sine uses the perpendicular which lies opposite to the angle considered.
