Answer:

$389.35

Step-by-step explanation:

A certain computer costs $599.00 at Best Buy. On Black Friday, it is on sale for 35% off.

So, after 35% off the price of the computer will reduce from $599.00.

We are asked to find the cost of the computer on Black Friday.

Therefore, the price of the computer will reduce by [599 \times \frac{35}{100}] = 209.65 Dollars.

And the reduced price on the Black Friday will be $(599 - 209.65) = $389.35 (Answer)

What’s the difference between x and 4 is greater than 10
daser333 [38]

Answer:

There is a whole range of speeds at which you are allowed to drive, not just one. In cases like this where there is more than one correct answer, we use inequalities, not equations, to represent the situation.

Inequalities are mathematical statements that define a range of values. They are easily recognizable because they contain the symbols <, ≤,>, or ≥.

The 2 main support rods for a barbeque grill are each 7.5 cm from the centre of the
sukhopar [10]

Answer:

  58.1 cm

Step-by-step explanation:

The length of each support rod can be found using the Pythagorean theorem. The geometry can be modeled by a right triangle, such that the distance from centre is one leg and half the length of the rod is the other leg of a triangle with hypotenuse equal to the radius of the grill.

__

<h3>Pythagorean theorem</h3>

The theorem tells us that the sum of the squares of the legs of a right triangle is the square of the hypotenuse. For legs a, b and hypotenuse c, this is ...

  c² = a² +b²

<h3>application</h3>

For the geometry of the grill, we can define a=7.5 and c=30. Then b will be half the length of the support rod.

  30² = 7.5 +b²

  b² = 900 -56.25 = 843.75

  b = √843.75 ≈ 29.0473

The length of each support rod is twice this value, so ...

  rod length = 2b = 2(29.0473) = 58.0947

Each support rod is about 58.1 cm long.

Cody's rent is increasing by $51 per month starting next year. That is an increase of 15% from his current monthly rent. Let r r
Inessa05 [86]

Answer:

r = 43.35

Step-by-step explanation:

Given

Current\ Rent = r

Increment = 15\%

New\ Rent = \$51

Required

Determine the value of r

The value of r can be set up percentage increase formula as follows:

\%Increment  = \frac{New\ Rent - Current\ Rent}{Current\ Rent}

Substitute values in the above equation

15\% = \frac{51 - r}{51}

Cross Multiply

51 - r = 15\% * 51

Convert percentage to decimal

51 - r = 0.15 * 51

51 - r = 7.65

And the value of r\ is\ calculated\ using:

r = 51 -7.65

r = 43.35

Hence, Cody's current rent is $43.35 monthly
