<u>Answer-</u>
The speed of wind is 13 mph
<u>Solution-</u>
We know that,
⇒
Let's assume, W = speed of wind
39 + W = speed with the wind
39 - W = speed against the wind
Time taken by him to travel with the wind
Time taken by him to travel against the wind
∴ As he takes same time for both the cases
⇒
⇒ 78 - 2W = 39 + W
⇒ 3W = 39
⇒ W = 13 mph
The Probability of choosing a green marble out of total 29 marbles is 11/29.
What is the Probability?
Probability defines the likelihood of occurrence of an event. There are many real-life situations in which we may have to predict the outcome of an event. We may be sure or not sure of the results of an event. In such cases, we say that there is a probability of this event to occur or not occur.
Total number of marbles = 11 Green + 18 Silver = 29 marbles
Number of Green marbles = 11
Probability = Number of green marble / Total number of marbles
= 11 / 29
Thus, The Probability of choosing a green marble out of total 29 marbles is 11/29.

Your answer is gonna be: 2.9
The diagonal of a cube is the square root of 3x^2, where x is a side length....The three dimensional diagonal is the counterpart to the two dimensional hypotenuse found in a right triangle...mathematically a three dimension diagonal can be found with an extension of the Pythagorean Theorem adapted to three dimensions...
d^2=x^2+y^2+z^2 but since we are dealing with a cube, x=y=z=s where s is a side lenght...
d^2=3s^2 and we are told that the diagonal is 30 in. so
3s^2=30^2
3s^2=900
s^2=300
s=√300
s=10√3 in. exact
s≈17.3 in. (to the nearest tenth of an inch)
