Multiply the given dimensions by (100cm/1m) to convert it to centimeters
<span>1.2(100cm/1m) = 120 cm </span>
<span>3.4(100cm/1m) = 340 cm </span>
<span>0.5(100cm/1m) = 50 cm </span>
<span>the volume of a box is equal to (length)(width)(height) </span>
<span>that is </span>
<span>V = (120cm)(340cm)(50cm) </span>
<span>V = (6000 cm^2)(340cm) </span>
<span>V = 2040000 cm^3 </span>
<span>now 1 cm^3 is equal to one mL and 1000 mL is 1 Liter </span>
<span>V =2040000 mL multiply by (1 Liter/1000 mL) </span>
<span>V = 2040 L </span>
<span>That's 2,040 liters.
Hope this helps :)</span>
Divide the numerator and denominator by 21:
21 / 21 = 1
84 / 21 = 4
So 21/84 is equal to 1/4.
Answer:
x^2\ 16 - y^2/9 = 1
step-by-step explanation:
soooo the equation for a hyperbola that is horizontal is x^2/a^2 - y^2/b^2 = 1
a hyperbola should always equal one so dont forget that when writing your equation becuase it is easy to forget.
it helps to graph this so you can see it better
to find a it is the distance from the center to the vertices which is 4 so in the equation you will write 16 becuase it is a^2
then you need to find b. to get b you have to figure out that c is the distance from the center to the foci which is 5 and it is all related to the plythagorm theorum becuase it forms a right triangle. so you do c^2 - a^2 = b^2
you get 9 for b^2 because 25-16=9 and so you put that in the equation
