Answer:
Solution
Step-by-step explanation:
Rewrite logx729= 3 is an exponential form using the definition of a logarithm. If x and b are positive real numbers and b≠1, then logb(x)= y is equivalent to b^y = x.
X^3 = 729
Take cube root on both side and we get
x= 3√729
now we firstly simplify the 3√729
Rewrite 729 as 9^3
x = 3√9^3
pull terms out from under the redical, assuming positive real numbers
x=9
verify each of the solution by substituting them into logx729=3 and solving.
x= 9

Rufina [12.5K]

Answer:

50%

Step-by-step explanation:

The only numbers that are multiples of 2 are all even numbers. From 1 to 10 there are a total of 5 even numbers, meaning that only 5 sections are multiples of 2. Therefore, the probability of the arrow landing in a section that is labeled with a number that is a multiple of 2 would be

5/10  if we simplify this it would be 1/2 or 50%

Finally, we can say that the probability of the arrow landing on one of these sections is 50%

A plumber had two pipes. The ratio of the length of the longer pipe to the shorter pipe was 9:2. When he cut 1.65m from the long
Natasha2012 [34]

Answer:

1.1m

Step-by-step explanation:

Let L denote longer pipe and S denote shorter part

given:

L:S = 9:2

or L/S = 9/2

2L = 9S

S = (2/9)L-----(eq 1)

Also given:

L - 1.65 = 3S

L - 3S = 1.65 ----- (eq 2)

By substitution, sub eq 1 into eq 2

L - 3(2/9)L = 1.65

L - (2/3)L = 1.65

L [ 1 - (2/3) ] = 1.65

L/3 = 1.65

L = 1.65 (3) = 4.95  (substitute into equation 1)

S = (2/9)(4.95) = 1.1m
