At Best Buy they have a stereo system that sells for $2200 and is on sale for 15% and sales tax is 7% what is the final cost

1 answer:

6 0

The sales price is 85% of the original $2,200, which can be calculated as follows: .85(2,200) = 1870 Assuming you meant 15% discount price..

Now we need to find a 7% sales tax, which can be calculated as follows:

.07(1870) = 130.90

Now we add the sale price and the sales tax: 1870 + 130,90 = $2000.90 for the total cost.

HELP PLSSSSS

Ipatiy [6.2K]

Answer: 11.4 feet of the ground

Step-by-step explanation:

You would use sin to get the answer. So it'd be sin(72) = x/12

Once you get the sin you would multiply it by the 12 to get the x by itself and that's your answer.

It would be sin because the question is asking for that side, and it's across the 72, making it the opposite side, the side that is across from the 90 degrees is always the hypotenuse and you have a number for that side and sin uses the opposite and hypotenuse

£140 is divided between Angad, Nick & June so that Angad gets twice as much as Nick, and Nick gets three times as much as Ju

kramer

Answer:

Step-by-step explanation:

Let's say Nick gets amount N, Angad amount A, and June amount J.

Here's what we know:

A+N+J=140

A=2*N

N=3*J.

Let's plug these values in.

N=3*J, so A+N+J=140 can now be A+3*J+J=140.

A=2*N, and N=3*J, so A=2*3*J=6*J. Then, A+3*J+J=140 is now 6*J+3*J+J=140, so 10*J=140 and J=14. N = 3*J=42 and A=2*N=84. Checking this, 14+42+84=140, so we are good to go!

Solve the equation<br> 56 ÷ (-8)= ?

Hunter-Best [27]

Answer:

-7

Step-by-step explanation:

Because for dividing one positive and one negative number, the rule is that the answer is going to be negative. So, what you can do is just do 56÷8 which equals 7 then add the negative sign to make it -7.

Which technique for gathering data (observational study or experiment) do you think was used in the following studies?(a) The Co

miv72 [106K]

Answer:

For question a, the correct option is: This is an observational study because observations and measurements of individuals are conducted in a way that doesn't change the response or the variable being measured.

For question b, the correct option is: This is an experiment because observations and measurements of individuals are conducted in a way that doesn't change the response or the variable being measured.

For question c, the correct option is: This is an experiment because a treatment was deliberately imposed on the individuals in order to observe a possible change in the response or variable being measured.

For question d, the correct option is: This is an observational study because observations and measurements of individuals are conducted in a way that doesn't change the response or the variable being measured.

Step-by-step explanation: To give us a background on why the options above were chosen, let us see the difference between Observational study and Experimental study.

In an observational study, the researcher draws inferences from an independent variable that is not under his/her control. While in an experimental study, there in an intervention and the effects of the intervention are studied.

Therefore, in the questions a to d above, all we need to do is identity which variables were influenced and which were merely observed.

For question a, the variables were only observed.

For question b, the variables were influenced.

For question c, the variables were also influenced.

For question d, the variables were merely observed.
