Answer:
120 pears
Step-by-step explanation:
Let the number of pears produced by Type B be x
Number of pears produced by type A=144
According to question
Type A produce 20% more pears than B
x+ x ×20%= 144
x+x×= 144
= 144
=144
x= 144×
x=120 pears
Hence, Number of pears produced by B= 120 pears
Hence, the correct answer is 120 pears
<u>Answer:</u>
The height of the ladder is 14.491 feet
<u>Explanation</u>:
Given the height is 11 feet
Base = 7 + 2 = 9 feet
Consider the ladder to be the hypotenuse
Applying Pythagoras Theorem,
Substituting the values in the above formula,
= 112 + 92
= 121 + 81
= 210
H = sqrt(210)
H = 14.491
Therefore, the height of the ladder is 14.491 feet
Answer:
9.694 years
Step-by-step explanation:
Let the investment is $P.
So, we are asked to determine the time it will grow to triple with the compound interest rate of 12%.
Let the time is y years.
So, from the formula of compound interest we can write
⇒
⇒
Now, taking log both sides we get,
y log 1.12 = log 3 {Since, }
⇒ 0.04922y = 0.477712
⇒ y = 9.694 years (Answer)
