Selling price is $607.50

Answer:

1500-40%= 900

1500-25%= 1125

1500-10%=1350

640-25%= 480

640-10%=576

$640-5%=608

Step-by-step explanation:

In order to calculate this you just need to mutliply the cost of the products by the amount that is not in disscount, for example the 1500 product has a disscount of 25% that means that the final cost will be 75% so 1500+.75=1125 and taht would be the cost.

The same with all of the other prices,  you taje the original price and multiply it by the decimal final percentage price, and you get the final price.

Solve cos x - square 1-3 cos^2 x = 0 given that 0° < x < 360°
Furkat [3]

Rearrange the equation as

cos(x) - √(1 - 3 cos²x) = 0

cos(x) = √(1 - 3 cos²x)

Note that both sides have to be positive, since the square root function is non-negative. If we end up with any solutions that make cos(x) < 0, we must throw them out.

Take the square of both sides.

(cos(x))² = (√(1 - 3 cos²(x))²

cos²(x) = 1 - 3 cos²(x)

4 cos²(x) = 1

cos²(x) = 1/4

cos(x) = ± √(1/4)

cos(x) = ± 1/2

We throw out the negative case and we're left with

cos(x) = 1/2

This has general solution

x = arccos(1/2) + 360° n   or   x = -arccos(1/2) + 360° n

(where n is any integer)

x = 60° + 360° n   or   x = -60° + 360° n

Now just pick out the solutions that fall in the interval 0° ≤ x < 360°.

• From the first solution set, we have x = 60° when n = 0.

• From the second set, we have x = 300° when n = 1.

So the answer is D.

Suzie made a mistake in the following problem. The mistake was made in Line ___. Only input the number of the first incorrect li
zalisa [80]

Answer:

Mistake in Line 2

Step-by-step explanation:

Line 1  

7(6) ÷ 5 + 42  

Line 2  

7(6) ÷ 5 + 16  

Line 3  

42 ÷ 5 + 16  

Line 4  

42 ÷ 21  

Line 5  

2

To simplify any expression we use order of operation

Line 1 is 7(6) ÷ 5 + 42  

Order of operation is PEMDAS

First we start with parenthesis

so we multiply 7(6) in line 2

7*6- 42

So Line 2 is 42 ÷ 5 + 42  

Hence there is a mistake in Line 2

7,4,5,2x,11, is 15 find the value of x​
sergejj [24]

Answer:

don't understand

but mean = <u>summation x</u>

total number

15=<u>7+4+5+2x+11</u>

5

15=<u>27+2x</u>

5

multiply both sides by 5

15×5=<u>2</u><u>6</u><u>+</u><u>2</u><u>x</u> ×5

5

75=26+2x

75-26=2x

<u>49</u>=<u>2x</u>

2. 2

x= 24.5
