We know that
[volume of a cone]=pi*r²*h/3
h=70 cm
r=15 cm
[volume of a cone]=pi*15²*70/3----------> 16485 cm³
if <span>Cathy uses 500 cm</span>³ of honey----------------> 1 day
<span>16485 cm</span>³--------------------------------------> X
<span>X=16485/500-----------> 32.97 days
the answer is 33 days </span>
Yes 921/3 = 307 873 is not divisible by 4 and 491 is also not divisible by 3
Answer: length: 7
Width: 6
Step-by-step explanation:
When h=0, that is when it hits the ground
0=70-4t-16t²
based on your previous questions, you should have learned how to complete the square
solve by copmleting the square
minus 70 both sides
-70=-4t-16t²
times both sides by -1
70=4t+16t²
16t²+4t=70
divide both sides by 16
t²+1/4t=35/8
take 1/2 of the linear coefint and square it
half of 1/4=1/8, (1/8)²=1/64
add that to both sides
t²+1/4t+1/64=35/8+1/64
factor perfect square trionomial



square root both sides, remember to take positive and negative roots

minus 1/8


or

the 2nd solution is not valid because that gives us a negative time, before the ball was dropped
so

is the solution
t≈1.97
1.97 seconds
(3 +

) × (3 -

)
Take the special case
(a - b)×(a + b)=a² - b²
a = 3
b =

3² - (

)² {(√)² = the number itself}
