Which of the below is not one of the properties of logarithms?

MrRa [10]

Answer:

option-B

Step-by-step explanation:

we know that

Sum rule of logarithm:

$log(a)+log(b)=log(a\times b)$

which is same as

the log of a product (ab) is equal to the addition of log a nad log b

Subtraction rule of logarithm:

$log(a)-log(b)=log(\frac{a}{b} )$

which is same as

the log of the quotient of a and b is equal to the log of a minus the log of b

Exponent rule of logarithm:

$log(a^b)=blog(a)$

which is same as

the log of the quantity a raised to b is equal to the product of b and the log of a

so,

option-B is not correct

Cheryl paid $37.20 for 12 gallons of ice cream for a school picnic. How much would 1 quart of ice cream cost?

Stells [14]

First, you need to get to one gallon, which is 37.20 divided by 12. (3.1)
Divide that number by four, which is: 0.775, or 0.78 rounded up to the nearest hundredth.
Hope that helped.

Can somebody help me solve for x?

Dahasolnce [82]

Let y = the distance between the top left corner and the bottom right corner

y^2 = 24^2 + 15^2

y^2 = 801

y = 3 * sqrt(89)

Now we can find x.

12^2 + x^2 = (3 * sqrt(89))^2

x^2 = 657

x = 3 * sqrt(73) or 25.63
