Step-by-step explanation:

A B and D C are parallel lines.

"slope" means inclination. and as you can imagine, parallel lines must have the same inclination, or they would not be parallel.

so, the slope of D C must be also 2/7.

same thing as with 5.

both lines are parallel and must therefore have the same slope.

so, the slope of D C is also 3/4. and the first answer is correct.

If 15 students share 26 brownies, how many would each student get?

slamgirl [31]

Hi, all we need to do is to divide the number of brownies by the number of students, and we will get the amount of how many would each student get.

26/15 = 1,73 brownies per student.

The radius r of a cone is increasing at a rate of 4in/min. The height h of the cone is always 4 times the radius. Find the rate

AlekseyPX

$\bf \textit{volume of a cone}\\\\
V=\cfrac{\pi r^2 h}{3}\qquad h=4r\implies V=\cfrac{\pi r^2 \cdot 4r}{3}\implies V=\cfrac{4\pi r^3}{3}\\\\
-----------------------------\\\\
\cfrac{dv}{dt}=\cfrac{4\pi }{3}\cdot 3r^2\cdot \cfrac{dr}{dt}\implies \cfrac{dv}{dt}=4\pi r^2\cdot \cfrac{dr}{dt}\qquad 
\begin{cases}
\frac{dr}{dt}=4\\\\
r=7
\end{cases}
\\\\\\
\cfrac{dv}{dt}=4\pi (7)^2\cdot 4$

Suppose $2000 is invested at 9% interest compounded continuously. How long will it take for the investment to grow to $10,000? U

Lady bird [3.3K]

Answer:

Step-by-step explanation:

sing the equation > A = Pe^rt

20000 = 10000e^0.1t > 10% = 0.1

2 = e^0.1t

log 2 = log e^0.1t > log to the base e

log 2 = 0.1t * 1 log e to the base e =1

0.6931 = 0.1t

t = 6.931

= 7 years
