54. log(20x) - log4 = 2

Mathematics

1 answer:

Luba_88 [7]4 years ago

4 0

Answer:

x=e^2/5

Step-by-step explanation:

log(20 x) - log(4) = 2

Add log(4) to both sides:

log(20 x) = 2 + log(4)

Cancel logarithms by taking exp of both sides:

20 x = 4 e^2

Divide both sides by 20:

And we get Answer:

x = e^2/5

The formula for area of a rectangle is length by width where the width is the height of the rectangle

Given that area=130 in²

Lets assume the length of this rectangle is =l inches

ExtremeBDS [4]

Answer:

Decreased by 20%.

16 lbs is 80% of 20 lbs.

$\frac{y}{100} :\frac{16}{20}$

y × 20 = 16 × 100

20y = 1600

20y ÷ 20 = 1600 ÷ 20

y = 80

100% - 80% = 20%
