How do I show the work for 5.4 divided by 39.42?

Answers

Answer 1

Answer: You have to move the decimal point right the same number of places for each one and divide normally so it would be 540/3942 and it is 0.13698630136986 which is irrational so you have to round to the nearest tenth, hundredth, or thousandth, depending on what the directions say.

Answer 2

Answer:
what you can do is to write what you type on your calculator. So type in 39.42/5.4=7.3

Multiplying complex numbers is a lot like multiplying binomial terms. The only relation one has to remember when dealing with complex numbers is that i² = -1.

Now let us try to multiply binomials. This is done by adding the products of the first term of the first binomial distributed to the second binomial, and the second term of the first binomial distributed to the second binomial. This is done below:

(3 – 5i)(–2 + 4i) = -6 + 12i + 10i -20i²

Simplifying and applying i² = -1:
-6 + 22i - 20(-1)
-6 + 22i + 20
14 + 22i

Among the choices, the correct answer is B.

Answer:

14 + 22i

Select all that apply.Jacqueline solved 80% of problems correctly in a math test whereas Marc solved only 65% of the problems correctly.

Let the event J = correct problems solved by Jacqueline,
and the event M = correct problems solved by Marc.
A. P(J) × P(M) = P(J ∩ M)
B. The probability that Jacqueline and Marc both can solve a problem in a math test is 0.93.
C. P(J) × P(M) = P(J ∪ M)
D. J and M are independent events.
E. The probability that Jacqueline and Marc both can solve a problem in a math test is 0.52

Answers

Answer:

Option A , D and E holds.

Step-by-step explanation:

Let the event J = correct problems solved by Jacqueline,

and the event M = correct problems solved by Marc.

Jacqueline solved 80% of problems correctly in a math

So, probability of correct problems solved by Jacqueline P(J)=0.80

Marc solved only 65% of the problems correctly.

So, probability of correct problems solved by Marc P(M)=0.65

Probability of correct problems Solved by Marc and Jacqueline :

= $P(J) * P(M)$

= $0.80*0.65$

= $0.52$

So, Option E is correct.

we also know that and means intersection .

So, P(J) × P(M) = P(J ∩ M)

So, Option A is also correct.

Since option A holds .

So, property of independent events is satisfied : $P(A) * P(B)=P(A \cap B)$

Thus Option D also holds.J and M are independent events.

Hence Option A , D and E holds.

The right answer for the question that is being asked and shown above is that: "E. The probability that Jacqueline and Marc both can solve a problem in a math test is 0.52; B. The probability that Jacqueline and Marc both can solve a problem in a math test is 0.93."

A ball is thrown horizontally from the top ofa building 110 m high. The ball strikes the
ground 61 m horizontally from the point of
release.
What is the speed of the ball just before it
strikes the ground?
Answer in units of m/s

Answers

The speed of the ball would be 13 m/s just before it strikes the ground.

A ball is thrown horizontally from the top of a 110 m high building. 61 meters horizontally from the moment of release, the ball falls on the earth.

What is the velocity?

Velocity is defined as the displacement of the object in a given amount of time and is referred to as velocity.

First of all, we get the time of aviation from the vertical component:

Here s = 110 m and g = 9.8 m/s²

s = 1/2 × gt²

Solve for t

t = √(2s/g)

Substitute the values of s = 110 m and g = 9.8 m/s² in the equation,

t = √(2×110/9.8)

t = √22.44

t = 4.7 sec

The horizontal component of velocity is constant :

v = s/t

Here s = 61 m and t = 4.7 sec

v = 61/4.7

v = 12.97 ≈ 13

Therefore, the speed of the ball would be 13 m/s just before it strikes the ground.

Answers

Answer:

Step-by-step explanation:

30%, 1/4, 0.725

you should make them all in the same form. for example, ¼ in decimal form is 0.25 and 30% is 0.3.

in conclusion, least to greatest would be
0.25, 0.30, then 0.725

or ¼, 30%, then 0.725
