First, add 3+3 which is 6/5. Next, you use KCF. 6/5 * 5/2. You now have to find a least common denominator. You can multiply 5*2 and 2*5 to both fractions. 6*2/5*2 simplifies to 12/10. Lets do the same to the other fraction except using 5 this time. We now get 5*5/2*5 = 25/10. We can now multiply across. 25*12/10*10. 300/100 which reduces to simply 3. You can double check this on a scientific calculator like I did and got the same answer.

The sales tax on the model rocket shown is $1.92. What is the percent of sales tax? A drawing of a model rocket with a tag label

astraxan [27]

Answer:

The sales tax is 8%

Explanation:

We are given that:

The price of the rocket is $24 and the sales tax is $1.92

To get the percentage of the sales tax, all we have to do is divide the sales tax by the price of the rocket and then multiply the quotient by 100 (to convert the ratio to percentage)

This is done as follows:

% of sales tax = $\frac{tax}{price}*100$

% of sales tax = $\frac{1.92}{24}*100 = 8$ %

Hope this helps :)

A company has two types of machines, type R and type S. Operating at a constant rate, a machine of type R does a certain job in

kozerog [31]

Answer: C. 6

Step-by-step explanation:

Given : Time taken by Machine R to do the job = 36 hours

Time taken by Machine S to do the job = 18 hours

Let x be the number of each type of machine to do the job.

Then , according to the question the required equation will be :-

$\dfrac{x}{36}+\dfrac{x}{18}=\dfrac{1}{2}\\\\\Rightarrow\ x(\dfrac{1}{36}+\dfrac{1}{18})=\dfrac{1}{2}\\\\\Rightarrow\ \dfrac{x}{12}=\dfrac{1}{2}\\\\\Rightarrow\ x=\dfrac{12}{2}=6$
