Answer:

The answer should be 2

Step-by-step explanation:

16 pi = 1/3 pi r^2 ( 12) Divide both sides by pi

16 = 1/3 r^2 (12) 1/3 * 12 = 4

16 = 4 r^2 divide both sides by 4

4 = r^2 You should be able to take it from here !

If a salesperson sells 3/4 of an acre for $80,000, what was the price per square foot rounded to two decimal spaces?

Julli [10]

Now, recalling that for 1 yard, there are 3 feet, therefore $\bf \begin{array}{ll}
yards&feet\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
1yd&3ft\\
(1yd)^2&(3ft)^2\\
yd^2&3^2ft^2\\
&9ft^2
\end{array}$

and keeping in mind that, there are 4840 yd² in 1 acre, then

$\bf \cfrac{\quad \frac{3}{4}~\underline{acre}\quad }{80000~\$}\cdot \cfrac{4840~\underline{yd^2}}{\underline{acre}}\cdot \cfrac{9~ft^2}{\underline{yd^2}}\implies \cfrac{\frac{3}{4}\cdot4840\cdot 9~ft^2}{80000~\$}\implies \cfrac{\frac{130680}{4}}{80000}
\\\\\\
\cfrac{\frac{130680}{4}}{\frac{80000}{1}}\implies \cfrac{130680}{4}\cdot \cfrac{1}{80000}\implies \cfrac{3267}{8000}~\frac{ft^2}{\$}~\approx~ 0.408375 ~\frac{ft^2}{\$}$

I need some help in geometry

kogti [31]

Answer:

JT = 29

Step-by-step explanation:

CT=CJ+JT

69= (4x+8)+ ( 3x+5)

69= 7x +13

7x= 69-13

7x= 56

x=56/7

x=8

JT=3x+5=3(8)+5= 24+5=29

I hope I helped you^_^

Find the slope of the line that passes through the pair of points (–1, –10) and (–3, 10).

svet-max [94.6K]

To find the slope of a line you only need two points. The first point is (x1,y1) and the second point is (x2,y2). The slope m is (y2-y1)/(x2-x1) = (10--10)/(-3--1)
= 20/ -2 = -10.
Answer: m = -10.
