Lucky you it's sale time at Best Buy! This TV was originally $229 it's now on sale for 25% off. How much is the TV now?

Answers

Answer:

0.000725 i think :)

Step-by-step explanation:

   Divide the number by 100 (move the decimal place two places to the left).

   Multiply this new number by the percentage you want to take off.

Answer- 171.75
You multiply your original cost (229) by the percent it’s on sale for (.25) then you get $57.25. That is how much is being taken off of the original price so you would subtract 229 by 57.25 to get your answer of $171.75.

Answers

Answer:

x= 2

Step-by-step explanation:

7x = 13x -12

0= 13x-12-7x

12= 13x-7x

12= 6x

2= x

you need to bring all the X's to one side then solve from there

Answer:

x=2

Step-by-step explanation:

7x=13x-12

Subtract 13x from both sides

7x-13x=13x-12-13

-6x=12

Divide both sides by -6

-6x/-6=-12/-6

The figure below shows a right triangle:

What is r ÷ p equal to? (6 points)

Group of answer choices

A. sin y°

B. sin x°

C. tan y°

D. tan x°

Answers

Answer:

tan y°

Step-by-step explanation:

by using the Sine Rule (See attached), we can form the equation:

[tex]\frac{r}{sin (y)} = \frac{p}{sin (x)}[/tex]

rearranging this, we get:

[tex]\frac{r}{p} =\frac{sin(y)}{sin(x)}[/tex]   ---------------------eq 1

Recall that all internal angles of a triangle must sum to 180°. we observe that we have a right triangle where one of the angles is 90°. It then follows that the sum of the other two angles must sum to 90°

i.e x + y = 90°

with a little rearranging, we get

x = (90° - y)

Substituting this into eq 1 above, we get:

[tex]\frac{r}{p} =\frac{sin(y)}{sin(90- y)}[/tex]  ---------eq 2

recall that from the trigonometric co-function identities,

sin (90°- y) = cos y

substituting this into eq 2 gives :

[tex]\frac{r}{p} =\frac{sin(y)}{cos(y)} = tan(y)[/tex]   (answer)

A recipe for cookies calls for 2/3 of a cup of sugar. Elena used 5 1/3 cups of sugar to make multiple batches of cookies. How many batches did she make?

Answers

Answer:

8 batches

Step-by-step explanation:

A recipe for cookies calls for 2/3 of a cup of sugar. Elena used 5 1/3 cups of sugar to make multiple batches of cookies. How many batches did she make?

From the above question, 1 recipe = 1 batch of cookies

Hence:

2/3 cup of sugar = 1 batch of cookies

5 1/3 cups of sugar = x batches of cookies

Cross Multiply

2/3 cup × x batches = 5 1/3 cup × 1 batch

x batches = 5 1/3 cup × 1 batch/2/3 cup

x batches = 16/3 ÷ 2/3

x batches = 16/3 × 3/2

= 8 batches

Therefore she made 8 batches

what is 3/4b>15 solution

Answers

The solution set of the given inequality is  {b| b > 20}.

How to solve the inequality?

Here we have the inequality (3/4)b > 15 and we want to solve it. To do so, we just need to isolate the variable b.

And to do it, we can work with this like we would do with any equation, we can just multipy both sides by (4/3) so we get:

(4/3)*(3/4)*b > 15*(4/3)

b > 20

Then the solution set can be written as {b| b > 20}

That is the set of all values larger than 20.

Step-by-step explanation:

Chenelle has a savings account that earns 5% simple interest each year. She can only deposit small amounts into her account each month. Should Chenelle keep her account open even though she can deposit only a small amount each month?

Answers

Answer:

Yes, she should.

Step-by-step explanation:

5% may not seem like a lot. Lets say she deposits $20 per month. That's $240 a year. Lets also say you keep this for 6 years, you'll have $72 from interest. The more amount she puts in the more she'll gain.

First, converting R percent to r a decimal

r = R/100 = 5%/100 = 0.05 per year,

then, solving our equation

I = 240 × 0.05 × 6 = 72

I = $ 72.00

The simple interest accumulated

on a principal of $ 240.00

at a rate of 5% per year

for 6 years is $ 72.00.

Yes, she should keep  her account open even though she can deposit only a small amount each month.

Calculation of keeping the account:

Since Chenelle has a savings account that earns 5% simple interest each year.

So here we assume that she deposit $20 per month

So for year it should be 240

And the number of years should be 6 so the interest be like 72

Now

I = 240 × 0.05 × 6

I = 72

Hence, Yes, she should keep  her account open even though she can deposit only a small amount each month.
