Answer: 1.25
Step-by-step explanation:
The equation which can be used to find the length of EF is option A which is EF=
.
Given the length of base of right angled triangle is 12 and the hypotenuse be 24.
We are to find the length of EF and tell which equation can be used to find the length of EF.
We know that pythagoras theorem applies in a right angled triangle.
Pythagoras theorem says that in a right angled triangle the square of the hypotenuse is equal to the sum of square of base and perpendicular.

In this triangle we are only given base and hypotenuse and we have to find EF which is perpendicular.

EF=
=
--1
=
=
Hence the equation which can be used to find the length of Ef is option A which is EF=
.
Question is incomplete as it should include the figure also.

For each of the possible outcomes add the numbers on the two dice and count how many times this sum is 7. If you do so you will find that the sum is 7 for 6 of the possible outcomes. Thus the sum is a 7 in 6 of the 36 outcomes and hence the probability of rolling a 7 is 6/36 = 1/6.
Answer:
<h2>
29.17m/s²</h2>
Step-by-step explanation:
Acceleration is defined as the change in velocity of a body with respect to time.
Acceleration = velocity/time
Given velocity of the space shuttle = 525m/s and time = 18.0seconds
Its average acceleration = 525/18
Its average acceleration (in m/s²) = 29.17m/s²
