Answer:
Step-by-step explanation:
So this is multiplication
24.5 times 20 in dollars is $4.90 if we round it than it will be 5 dollars
Answer:

Step-by-step explanation:
We have been given that a certain function is an inverse proportion. We are asked to find the formula for the function if it is known that the function is equal to 12 when the independent variable is equal to 2.
We know that two inversely proportional quantities are in form
, where y is inversely proportional to x and k is constant of variation.
Upon substituting
and
in above equation, we will get:

Let us solve for constant of variation.


Now, we will substitute
in inversely proportion equation as:

Therefore, the formula for the given scenario would be
.
Answer:
48 soldiers leave the place.
Step-by-step explanation:
- 100/60=80/x
- 100x=4800
- x=4800/100
- x=48

I would say D my dear friend from what i see from the patterns hope it helps :) and sorry if its wrong i tried lol
The a and b determine how big or small the shape of the conic section is.
<span>For the different conic sections given through the equations </span>
<span>Circle: x^2/a^2 + y^2/a^2=1 </span>
<span>Ellipse: x^2/b^2+y^2/a^2 = 1 </span>
<span>Hyperbola: x^2/a^2 - y^2/b^2 = 1 </span>
<span>When trying to isolate cos and sin from those equations to get cos^2t + sin^2 t = 1 you can determine the conic section when substituting cos t = x/a and sint = y/b into cos^2t+sin^2t square it and then refer to the conic section equations to determine the conic section. x defines the major axis and y is the minor axis. a and b provide the coordinate pairs</span>
