If the cost of a 2.5 meter cloth is $30.5. What will be the cost of 22 meters ?

alisha [4.7K]

Answer:

268.40

Step-by-step explanation:

We can write a ratio to solve

2.5 meters 22 meters

----------------- = --------------

30.5 dollars x dollars

Using cross products

2.5 * x = 30.5 * 22

2.5x =671

Divide each side by 2.5

2.5x / 2.5 = 671/2.5

x =268.4

What is the solution to 2logg(x) = logg8+log,(x-2)? x=-4 x=-2 X=4 X= 8

astra-53 [7]

Answer:

x = 4

which agrees with the third listed answer among the given options

Step-by-step explanation:

We can re-write the logarithmic equation using the properties of logarithms:

$2\,log(x)=log(8)+log(x-2)\\log(x^2)=log(8*(x-2))\\log(x^2)=log(8x-16)$

Therefore, the arguments of the log functions must also be equal (and we can solve for "x" by noticing that this expression is the perfect square of a binomial:

$x^2=8x-16\\x^2-8x+16=0\\(x-4)^2=0$

and for this equation to verify, x must be 4

a 40-foot ladder leans outside against a the cafeteria. The ladder’s base is 20 feet from the cafeteria. To the nearest degree,

eimsori [14]

Answer:

60 degrees.

Step-by-step explanation:

We use trigonometry of a right angled triangle:

Adjacent side = 20 ft, Hypotenuse = 40 ft.

cos x = adjacent / hypotenuse = 20/40 = 1/2

x = 60 degrees.
