Answer:

The shop made a profit about $40.

Step-by-step explanation:

Now, According to the question We know that :

The shop marked the $200 price up by 60%.

60% of $200 is = $120.

Now, the price is = $320 because, 200 + 120 = 320.

Joseph bought the tennis racket at 25% off.

25% of $320 is = $80.

Now, the discount price is = $240 Because, 320 - 80 = 240.

So, Joseph bought the racket for = $240.

Now we know that the original price from the factory was $200.

Joseph bought it for $240.

So, the shop made a profit of $40.

Well to find the value of the interior angle of a hexagon it would be out of a total of 720 degrees therefore just subtract the values of the known interior angle values and you should be able to get the value of the interior angle of X

How many numbers are from k to n? (Including k and n.)

shepuryov [24]

Answer:

n - k + 1

Step-by-step explanation:

This is assuming (because you did not say) that n and k are integers and n is greater than k.

Example: from 2 to 5 {2, 3, 4, 5} includes 5 - 2 + 1 = 4 numbers.

Example: from -6 to 4 includes 4 - (-6) + 1 = 11 numbers, namely {-6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4}

valerie has 8 blue markers and 10 green markers. she has 2 times as many red markers as blue and green markers combined. which d

aleksley [76]

This question means the than (8 + 10) x 2 = red markers. She has 32 red markers, 8 blue markers, and 10 green markers. If you add them all up, you get 50 markers.

What are the two missing sides of the triangle ??

igor_vitrenko [27]

Remark
It's a right triangle so the Pythagorean Theorem applies. All you have to do is put the right things in the right places of the formula.

Givens
a = x
b = x + 4
c = 20

Formula and Substitution.
a^2 + b^2 = c^2
x^2 + (x + 4)^2 = 20^2

Solution
x^2 + x^2 + 8x + 16 = 20 Collect the like terms on the left.
2x^2 + 8x + 16 = 20 Subtract 20 from both sides.
2x^2 + 8x + 16 - 20 = 0
2x^2 + 8x - 4 = 0 Divide through by 2
x^2 + 4x - 2 = 0

Use the quadratic formula
a = 1
b = 4
c = - 2

$\text{x = }\dfrac{ -b \pm \sqrt{b^{2} - 4ac } }{2a} 
$
$\text{x = }\dfrac{ -4 \pm \sqrt{4^{2} + 4(1)(2) } }{2} 
$

From which x = (-4 +/- sqrt(24) ) / 2
x1 = (- 4 +/- sqrt(4*6) ) / 2
x1 = (- 4 +/- 2 sqrt(6) ) / 2
x1 = -2 + sqrt(6)
x2 = -2 - sqrt(6) This is an extraneous root. No line can be minus.

x1 = + 0.4495
x2 = x + 4 = 4.4495
