Help I was never taught how to do this im confused

Mathematics
1 answer:
vazorg [7]3 years ago

Answer:

36

Step-by-step explanation:

Area of a triangle = (bh)/2

Where b = base length and h = height

Given base length: 18ft

Given height: 4ft

This being known let's define the variables

b = 18

h = 4

Now to find the area we simply plug in these values into the formula

Area = (18)(4)/2

Simplify multiplication 18 * 4 = 72

Area = 72/2

Simplify division

Area = 36

You sell candy at a football game for $1.50 each. You paid $50 for 300 candy bars. what is the domain and range for your profit?
-Dominant- [34]

Answer:

Domain is number of candy or 300

Range is profit from selling candy or $50

Step-by-step explanation:

Domain is the numbers you are allowed to use in your function. In this case, it would be the amount of candy you sold.

The range is the output from inputting the number(s) in the domain. In this case, the range is the amount of money you profit.

Profit=(amount gained)-(amount lost)

amount gained is from selling candy

amount lost is what you invested to get the candy

amount gained=(cost per candy)X(number of candy)

amount gained=(1.50)(300)

amount gained=$450

amount lost=$50

therefore

Profit=450-40=$400

a function for profit can be as follows:

P(x)=1.5x-c

where amount you sold each candy for, c is cost for those x candies, and P(x) is the profit for x candies

How do you find the total length when you have the coordinates of the midpoints?
son4ous [18]
Check the picture below, so, those red ones are the midpoints you found.

\bf \textit{distance between 2 points}\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
%  (a,b)
\stackrel{midpoint}{KL}&({{ 3}}\quad ,&{{ 1}})\quad 
%  (c,d)
\stackrel{midpoint}{JM}&({{ -2}}\quad ,&{{ -1}})
\end{array}
\\\\\\
d = \sqrt{({{ x_2}}-{{ x_1}})^2 + ({{ y_2}}-{{ y_1}})^2}\implies d_1=\sqrt{(-2-3)^2+(-1-1)^2}
\\\\\\
d_1=\sqrt{(-5)^2+(-2)^2}\implies d_1=\sqrt{25+4}\implies d_1=\sqrt{29}\\\\
-------------------------------\\\\


\bf \textit{distance between 2 points}\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
%  (a,b)
\stackrel{midpoint}{JK}&({{ -1}}\quad ,&{{ 2}})\quad 
%  (c,d)
\stackrel{midpoint}{ML}&({{ 2}}\quad ,&{{ -2}})
\end{array}
\\\\\\
d = \sqrt{({{ x_2}}-{{ x_1}})^2 + ({{ y_2}}-{{ y_1}})^2}\implies d_2=\sqrt{[2-(-1)]^2+[-2-2]^2}
\\\\\\
d_2=\sqrt{(2+1)^2+(-4)^2}\implies d_2=\sqrt{9+16}\implies d_2=5

now, that many units are each distance for those "medians", hmmm now, recall that each unit is meant to be 10 meters, so, just multiply each by 10, to get how many meters long each one is.
