A cube-shaped tank that measures 4.64.6 meters on each side is full of water. If some water is drained to fill a cone with a hei

rusak2 [61]

Answer:

The amount of water left in the tank is approximately 58.1 cubic meters

Step-by-step explanation:

step 1

Find the volume of the a cube shape tank

The volume is equal to

$V=b^{3}$

we have

$b=4.6\ m$

substitute

$V=4.6^{3}=97.336\ m^{3}$

step 2

Find the volume of cone

The volume is equal to

$V=\frac{1}{3}\pi r^{2}h$

we have

$r=2.5\ m$

$h=6\ m$

$\pi =3.14$

substitute

$V=\frac{1}{3}(3.14)(2.5)^{2}(6)$

$V=39.25\ m^{3}$

step 3

Find the difference of the volumes

$97.336\ m^{3}-39.25\ m^{3}=58.1\ m^{3}$

How much would $100 invested at 8% intrest compounded annually be worth after 15 years? round your answer to the nearest cent. d

frosja888 [35]

Our P = 100, r = .08, n = 1 (annually means once a year), and t = 15. Filling in accordingly, we have $A(t)=100(1+ \frac{.08}{1})^{(1)(15)}$ . Simplifying a bit gives us $A(t)=100(1+.08)^{15}$ and $A(t)=100(1.08)^{15}$ . Raising that number inside the parenthesis to the 15th power gives us $A(t)=100(3.172169114)$ . Multiplying to finish means that A(t) = $317.22

What is the slope of a line perpendicular to the line whose equation is 3x-7y+14=0?

tatyana61 [14]

1. Find the slope of the given line. Do this by solving 3x-7y+14=0 for m:

3x + 14 = 7y, which gives us m = 3/7.

2. Find the slope of a line perpendicular to this one. It's the negative reciprocal of m = 3/7, or -7/3.

What is the value of y? 72° A. 1080 B. 540 C. 36° D. 720

nadya68 [22]

Answer:

B. 54

Explanation:

Take 72 from 180.

180 - 72 = 108.

Since there are two y's AND they're congruent, divide 108 by two and get 54.
