Answer:

t=\frac{A}{pr}-\frac{1}{r}


Step-by-step explanation:

The equation given is A=p+prt

Doing some algebra manipulation, we can solve for t:

A=p+prt\\prt=A-p\\t=\frac{A-p}{pr}\\t=\frac{A}{pr}-\frac{p}{pr}\\t=\frac{A}{pr}-\frac{1}{r}


So t=\frac{A}{pr}-\frac{1}{r}

lys-0071 [83]
C - 0.17c = 0.83c
When you write “c” at the start, or x or whatever, it has an understood (invisible) number 1. So you’re subtracting the decimal on the next variable from 1.

Remove parentheses and simplify 7a+6b-4 (3a-3b)
Varvara68 [4.7K]
Normally, you would do whatever is inside of the parenthesees first then do the rest but we cant get any further so we remove the parenthasees by distrubtion

7a+6b-4(3a-3b)
-4(3a-3b)
a(b+c)=(ab)+(ac)
-4(3a-3b)=-12a-(-12b)

7a+6b-12a+12b
7a-12a+6b+12b
-5a+18b
that's the asnwer

Complete the equation of the graphed linear function in point-slope form.
BlackZzzverrR [31]
They are using the point (2, 8) to write this equation.  You know that because of the "y-8" in the equation, and also because it's bolded! lol.  Anyways, what's missing is the slope and the x value from our point.  The slope is -2.  Find this by picking 2 points on the line and putting those into the slope equation.  Use the bolded point and the x-intercept: (2,8) and (6,0):m= \frac{0-8}{6-2}= \frac{-8}{4}=-2.  As stated earlier the x coordinate in the bolded point is 2.  So our equation is y-8=-2(x-2).  And there you Go!

Find the area ratio of a regular octahedron and a tetrahedron regular, knowing that the diagonal of the octahedron is equal to h
Anton [14]

Answer:

\frac{4}{3}

Step-by-step explanation:

The area of a regular octahedron is given by:

area = 2\sqrt{3}\ *edge^2. Let a is the length of the edge (diagonal).

area = 2\sqrt{3}\ *a^2

Given that the diagonal of the octahedron is equal to height (h) of the tetrahedron i.e.

a = h, where h is the height of the tetrahedron and a is the diagonal of the octahedron. Let the edge of the tetrrahedron be e. To find the edge of the tetrahedron, we use:

h=\sqrt{\frac{2}{3} } e\\but\ h=a\\a=\sqrt{\frac{2}{3} } e\\e=\sqrt{\frac{3}{2} }a

The area of a tetrahedron is given by:

area = \sqrt{3}\ *edge^2 = \sqrt{3} *(\sqrt{\frac{3}{2} }a)^2=\frac{3}{2}\sqrt{3}    *a^2

The ratio of area of regular octahedron to area tetrahedron regular is given as:

Ratio = \frac{2\sqrt{3}\ *a^2}{\frac{3}{2} \sqrt{3}*a^2} =\frac{4}{3}
