What does 6÷3/4 equal

alex41 [277]

Answer:

Step-by-step explanation:

When you divide by a fraction, you can also say that you are multiplying by the reciprocal.

So $6/\frac{3}{4}=6*\frac{4}{3}$

$6=\frac{6}{1}$

$\frac{6}{1}*\frac{4}{3}=\frac{24}{3}=8$

The temperature dropped 5 degrees every hour during 8 hours. How much the temperature drop in all?

Murrr4er [49]

Answer:

<h3>40 degrees</h3>

Step-by-step explanation:

If the temperature dropped 5 degrees every hour, this can be expressed as;

5 degree = 1 hour

To get the total number of degree dropped fro 8hours, we will say;

x degree = 8hours where x is the temperature drop in all

Solving both equality

5 degree = 1 hour

x degree = 8 hours

cross multiply

x * 1 = 5 * 8

x = 40 degrees

<em>Hence the total temperature drop in all is 40°</em>

I need answer Immediately pls!!!!!!

Illusion [34]

Given:

Total number of students = 27

Students who play basketball = 7

Student who play baseball = 18

Students who play neither sports = 7

To find:

The probability the student chosen at randomly from the class plays both basketball and base ball.

Solution:

Let the following events,

A : Student plays basketball

B : Student plays baseball

U : Union set or all students.

Then according to given information,

$n(U)=27$

$n(A)=7$

$n(B)=18$

$n(A'\cap B')=7$

We know that,

$n(A\cup B)=n(U)-n(A'\cap B')$

$n(A\cup B)=27-7$

$n(A\cup B)=20$

Now,

$n(A\cup B)=n(A)+n(B)-n(A\cap B)$

$20=7+18-n(A\cap B)$

$n(A\cap B)=7+18-20$

$n(A\cap B)=25-20$

$n(A\cap B)=5$

It means, the number of students who play both sports is 5.

The probability the student chosen at randomly from the class plays both basketball and base ball is

$\text{Probability}=\dfrac{\text{Number of students who play both sports}}{\text{Total number of students}}$

$\text{Probability}=\dfrac{5}{27}$

Therefore, the required probability is $\dfrac{5}{27}$ .
