We know that
volume of a cylinder=pi*r²*h
r=√[V/(pi*h)]
r=10 m
A <span>second cylinder has
V2=V-----> volume of the second cylinder
h2=25*h----> height of the second cylinder
r2----> radius of the second cylinder
r2=</span>√[V2/(pi*h2)]----> r2=√[V/(pi*25*h)]---> r2=(1/5)*√[V/(pi*h)
r2=(1/5)*10-----> r2=2 m
the answer is
<span>the radius of the second cylinder is 2 m</span>
Answer:
Un excursionista camina por un prado llano, observando una montaña a
lo lejos. Mide que el ángulo de elevación entre el suelo
y la cima de la montaña es de 25 grados. Camina 5 millas y luego
mide el ángulo de elevación nuevamente, ahora es de 40 grados. ¿Qué altura tiene
la montaña?
Step-by-step explanation:
Answer:
$38.64
Step-by-step explanation:
Multiply the original price, $48.60 by 0.75 to get the discounted price. This gets you $36.45. Then multiply this by 0.06 to get the sales tax ($2.187) and add this to the sale price (36.45+2.187). This gets you $38.637 which you would round up to $38.64
Answer:
Step-by-step explanation:
<u>The filling speed is 30 hours or:</u>
<u>The draining speed is 34 hours or: </u>
<u>If both lines are open simultaneously, the filling speed is:</u>
- 1/30 - 1/34 =
- 17/510 - 15/ 510 =
- 2/510 =
- 1/255 in an hour
<u>If the tank is 1/5 full, then we need to fill the 4/5 of level and it will take:</u>
- 4/5 : 1/255 =
- 4/5 *255 =
- 204 hours
Step 1. Equation B could not have simplified out to 3y= 3 - 4z because Equation A's original equation was y= 15 - 2z. That means after the multiplication by -3, -3(y)= -3(15 - 2z) it would equal -3y= -45 + 6z.
