Let's use Pythagorean theorem.
where
is the hypotenuse.
So if we set it up:
now we simplify:
and get
by itself:
Now to get
by itself, we need to take the square root of both sides:
And that's your answer!
Answer:
To determine the circumference, of the circle what you would need to do is to use the formula for the Circumference.
This formula can be seen as : C = Pi x Diameter.
C = 2 x Pi x R.
Answer:
the answer is 14 converting 1and 1/6 to improper fraction gives u 7/2 then dividing by 1/12 is 14
Answer:
Step-by-step explanation:
We need a system of equations to help us solve this. One of the equations in the system is about the number of cultures bought, and the other one is about the money spent on the cultures. They are 2 very different things!
The #'s equation says that the number of cultures (c) plus the number of vials (v) totaled 57. The equation that puts that together is
c + v = 57
Now for the money part. Each culture costs $8, so the expression for that is 8c; each vial costs $1, so the expression for that is 1v; we know the amount of money spent in total was $106. The equation for that is
8c + 1v = 106
There's our system. 2 unknowns need 2 equations. Go back to the first one and solve it for either c or v. I'll solve for c, just because:
c = 57 - v. Now sub that value for c into the money equation:
8(57 - v) + v = 106 and
456 - 8v + v = 106 and
-7v = -350 so
v = 50. There are 50 vials of fruit flies. To find c, plug that into the first equation:
c + 50 = 57 so
c = 7.
Possibly d, because it’s a reflection
