The speed of wind and speed of plane in still air are 23 and 135
km/h respectively.
<u>Step-by-step explanation:</u>
Let the speed of wind and speed of plane in still air are w and p km/h respectively.
The effective speed on onward journey was
................(1)
The effective speed on return journey was
..............(2)
Adding equation (1) and equation (2) we get,
⇒
⇒
⇒
Putting value of in we get:
⇒
⇒
⇒
Therefore ,The speed of wind and speed of plane in still air are 23 and 135
km/h respectively.
Answer:
9sqrt(2) ft or 12.73 ft
Step-by-step explanation:
A = L^2
sqrt(162) = 9sqrt(2)
The diagonal of a square is equal to the side length.
Answer:
The volume of a prism on its own = 248.5cm^3
The volume of a cylinder = 87.92cm^3
Step-by-step explanation:
The volume does not change for the prism as the hole was drilled.
We can show the drilled space with v(l) and (p) for prism V
v(l) 248.5p - 87.92p + 87.92p
= 248.5p
Answer:
The answer is "Experimental Probability ".
Step-by-step explanation:
The probability of experiments is uncertainty which is calculated several times as per the outcome of even an experiment. The probability distribution is probably dependent upon reasoning. This probability is a price of about one or zero. It was based on the relative frequency or what occurs during a probability test.
