Answer:
d < -5
Step-by-step explanation:
Okay, so the equation is -5(d-2)>35
First we have to use distributive property to get rid of the parenthesis.
we do -5(d) --> -5d
then, -5(-2) --> 10
So now we just redo the equation---
-5d + 10 > 35
now you have to isolate d, the variable
First, to isolate you have to get rid of 10. Subtract 10 on both sides.
-5d + 10 > 35
- 10 -10
----------------------
-5d > 25
Then you have -5d > 25. You have to do the opposite operation again to make the d by itself, so you divide -5 on each side.
-5d > 25
----- -----
-5 -5
-5d/-5 is d because the -5's cancel out. 25/-5 is -5. Now, you have to flip the equation because when working with inequalities, you have to flip the symbol.
SO,,, the answer is
d < -5
Hope this helps!!

Who says V1=V2?
if we simplify we get
(2/3)pir₁³=12pir₂²
for V1 to equal V2
a.
solve for r₁ to find r₁ as a function of r₂
(2/3)pir₁³=12pir₂²
times 3/2 both sides and divide by pi
r₁³=18r₂²
cube root both sides
r₁=∛(18r₂²)
if solve for r₂
(2/3)pir₁³=12pir₂²
divide by 12pi both sides
(1/18)r₁³=r₂²
squer root both sides
√((1/18)r₁³)=r₂
double radius of pond which is r1
√((1/18)r₁³)=r₂
r₁ turns to 2r₁ to double radius
√((1/18)(2r₁)³)=r₂double
√(8(1/18)(r₁)³)=r₂double
(√8)(√((1/18)(r₁)³))=r₂double
√((1/18)r₁³)=r₂ so
(√8)(r₂)=r₂double
(2√2)(r₂)=r₂double
the radius of the tank is multipled by 2√2
I am pretty sure you would do 396x.25 on a calculator and then do that answer and x's it by 3 and that equals 297
