Answer:
3/10
6/20
Step-by-step explanation:
We need to find the number of bucks
4 does + 3 fawns + x bucks = 10
4 + 3 +x = 10
7+ x = 10
Subtract 7 from each side
x = 3
There are 3 bucks
3/10 is the fraction of bucks
Multiply the top and bottom by 2
3/10 * 2/2 = 6/20 is an equivalent fraction
Step-by-step explanation:
3 is cross multiplication
2 is proportion
and 1 is equal
Since the solution cannot be negative hence the true solution to the expression is x = 10
<h3>Laws of logarithm</h3>
Given the logarithmic expression
ln 20 + ln 5 = 2lnx
In logarithmic law, the sum of log is equivalent to its product .The equation above can be written as:
ln(20*5) = 2lnx
ln100 =2lnx
ln100 = lnx^2
x^2 =100
x = 10
Since the solution cannot be negative hence the true solution to the expression is x = 10

<h3>The ladder will reach a height of 11.8 feet up the wall</h3>
<em><u>Solution:</u></em>
The ladder, wall and base of the ladder from wall forms a right angled triangle
Length of ladder forms the hypotenuse
Length of ladder = 12 foot
base of the ladder from wall = 2 feet
<em><u>To find: height of wall</u></em>
By pythagoras theorem.

Where,
"c" is the Length of ladder
"a" is the base of the ladder from wall
"b" is the height of wall
Substituting the values,

Thus, the ladder will reach a height of 11.8 feet on wall
