Pick 1: 3 apples out of 11 pieces of fruit → 3/11
Pick 2: 4 oranges out of 10 pieces of fruit → 4/10 = 2/5
Pick 1 AND Pick 2
3/11 x 2/5 = 6/55
Answer:
well that depends on how many pieces of gum are in one pack, once you have that info multiply it by 4.
Step-by-step explanation:
Answer:
t=11,11 days
Step-by-step explanation:
F=frogs poblation, t=time, be the variables dF/dt = KF, dF/F=Kdt, integrating
⇒ LnF=Kt+c,
; Knowing t=0, F=17 and t=6 F=51 (tripling every 6 days (17*3)),
⇒
, so
, now if F=130, t=? we have:
![130=17e^{0.183t} =e^{0.183t} =130/17; 0.183t=ln(130/17); t=ln(130/17)/0.183 = 11,11](https://tex.z-dn.net/?f=130%3D17e%5E%7B0.183t%7D%20%3De%5E%7B0.183t%7D%20%3D130%2F17%3B%200.183t%3Dln%28130%2F17%29%3B%20t%3Dln%28130%2F17%29%2F0.183%20%3D%2011%2C11)
1/2 gallon of paint covers 1/12 of a wall
, 12 times as much paint will cover 12 times the area you can solve this by 12*1/2=6.
In seven days they washed a total of 638.85 pounds of laundry. This means each day they washed about 91.26 pounds of laundry.
