Answer:

$x=-64$

Step-by-step explanation:

$\frac{x}{4} -16=-32$

Add 16 to both sides.

$\frac{x}{4} -16+16=-32+16$

Simplify.

$\frac{x}{4} =-16$

Multiply both sides by 4.

$\frac{4x}{4} =4(-16)$

Simplify.

$x=-64$

A pair of snow boots at an equipment store in Big Bear that originally cost $80 is on sale for $56. What is the rate of discount

8_murik_8 [283]

Divide the sale price by the original price:

56 / 89 = 0.7

Multiply by 100:

0.7 x 100 = 70%

The sale price is 70% of the original price, so the discount would be 30% (100-70= 30)

The half-life of lead is 22 years. How long will it take for a sample of this substance t decay to 80% of its original amount?

Svetlanka [38]

Answer: 7 years

Step-by-step explanation:

$t_{\frac{1}{2} }$ = In2 / ∧

since the half life is given , we have :

22 = In 2/ ∧

∧ = In2/22

∧ = 0.032

Recall the formula for half life:

$\frac{N(t)}{N(0)}$ = $e^{-∧t}$

Therefore:

0.80 = $e^{-0.032t}$

Take the In of both sides

In 0.80 = - 0.032t

t = In 0.80 / - 0.032

t = 7 years
