Evaluate log12 - log4 + log5 and can you explain it to me?

1 answer:

7 0

Remember some simple log rules

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

work from left to right

$log(12)-log(4)+log(5)=$
$log(\frac{12}{4})+log(5)=$
$log(3)+log(5)=$
$log(3*5)=$
$log(15)$

The product of 6 and the quantity 9 more then the number x is 253

allochka39001 [22]

Answer:

$6(x+9)=253$

Step-by-step explanation:

we know that

The algebraic expression of the phrase"The product of 6 and the quantity 9 more then the number x is 253" is equal to the number 6 multiplied by the sum of x and 9 and this result is equal to 253

$6(x+9)=253$

solve for x

$6x+54=253$

$6x=253-54$

$6x=199$

$x=199/6$

PLEASE HELP I DONT KNOW HOW TO DO THIS

sergij07 [2.7K]

Answer:

step by step

Step-by-step explanation:

where

r = radius

h= height

Area of a cylinder = 2πrh+2πr^2

Area of a cylinder = 2π8(3)+2π8^2

Area of a cylinder = 176π = 552.92

Area of a hemisphere= 3r2π

Area of a hemisphere= 3(2)2π

Area of a hemisphere= 12π = 37.699111843

Area of the cylinder in this problem

176π - 12π = 164π

How do you find the missing height of a triangle?

g100num [7]

Answer:

Use the Pythagorean theorem

Step-by-step explanation:

The pythagorean theorem is $a^{2} +b^{2} =c^{2}$ where a is a height, b is a height, and c is the hypotenuse, which is the longest side of a triangle. For example, if the triangle has two side with lengths of three and four we would put them into the equation to get:
