A restaurant sees about 600 orders on Tuesday. This is down from last Tuesday by about 0.85%. How many did they see last Tuesday
zaharov [31]

Answer:

Number of orders seen on last Tuesday = 605

Step-by-step explanation:

Number of orders seen on Tuesday = 600

It is given that it is 0.85% less than last Tuesday.

Let number of sales on last Tuesday = x

As per question statement:

Number of order on last Tuesday - 0.85% of Number of order on last Tuesday = 600

OR

i.e. if we subtract 0.85% of x from x, it must be equal to 600.

x-\dfrac{0.85}{100}x =600\\\Rightarrow x-\dfrac{0.85}{100}x =600\\\Rightarrow \dfrac{100-0.85}{100}x =600\\\Rightarrow \dfrac{99.15}{100} \times x =600\\\Rightarrow x =\dfrac{600\times 100}{99.15}\\\Rightarrow x =\dfrac{60000}{99.15}\\\Rightarrow x \approx 605

So, there were about 605 order seen last Tuesday.

Find the length of x round your answer to the nearest hundredth
allsm [11]

Answer:

x = 7.55

Step-by-step explanation:

We can use the Pythagorean theorem to solve

a^2 +b^2 = c^2

where a and b are the legs and c is the hypotenuse

a^2 +8^2 = 11^2

x^2 +64 = 121

Subtract 64 from each side

x^2 +64-64 = 121-64

x^2 =57

Take the square root of each side

sqrt(x^2) = sqrt(57)

x = 7.549834435

To the nearest hundredth

x = 7.55

24. Use the intercepts to graph the equation.
romanna [79]

Answer:

See below ~

Step-by-step explanation:

<u>Finding x-intercept</u>

  • Take y = 0
  • 2x - 5(0) = 10
  • 2x = 10
  • x = 5
  • x-intercept is at (5, 0)

<u>Finding y-intercept</u>

  • Take x = 0
  • 2(0) - 5y = 10
  • -5y = 10
  • y = -2
  • y-intercept is at (0, -2)

<u>Graph (with points marked)</u>
