152640 grams per day

10^2 is 100

4.5 x 100= 450 grams per person per day

3.2 x 106=339.2

339.2 x 450= 152640

18 divide by 2 * 3/5-2 simplify show all work

liraira [26]

Answer:

Step-by-step explanation:

I would guess it looks like this - if not then tell me

$\frac{18}{ \frac{2 \times 3}{5 - 2} }$

2×3=6

5-2=3

Then there's only

$\frac{18}{ \frac{6}{3} }$

Which is equal to

$\frac{18}{1} \times \frac{3}{6} = \frac{54}{6} = \frac{9}{1} = 9$

What is the area of a triangle whose vertices are D(3,3), E(3,-1), and F(-2,-5)?

Elis [28]

There is a formula which employs the use of determinants and which helps us calculate the area of a triangle if the vertices are given as $(x_1,y_1),(x_2,y_2),(x_3,y_3)$ . The formula is as shown below:

Area= $\frac{1}{2}\begin{vmatrix}x_1&y_1&1 \\ x_2&y_2&1\\ x_3&y_3&1\end{vmatrix}$

Now, in our case, we have: $(x_1,y_1)=(3,3)$

$(x_2,y_2)=(3,-1)$ , and

$(x_3,y_3)=(-2,-5)$

Thus, the area in this case will become:

Area= $\frac{1}{2}\begin{vmatrix}3&3&1 \\ 3&-1&1\\ -2&-5&1\end{vmatrix}$

Therefore, Area= $\frac{1}{2}\times [[3(-1\times 1-(-5)\times 1]-3[3\times 1-(-2)\times 1]+1[3\times -5-2]]= \frac{1}{2}\times -20=-10$

We know that area cannot be negative, so the area of the given triangle is <u>10 squared units</u>.
