Mathematics

There are 14 tables with 8 chairs and 26 tables with 6 chairs in the cafe.

Step-by-step explanation:

Given,

Total tables at the cafeteria = 40

Table with 8 chairs = 35% = \frac{35}{100}=0.35

Tables with 6 chairs = 65% = \frac{65}{100}=0.65

Number of tables with 8 chairs = 0.35*Total tables

Number of tables with 8 chairs = 0.35*40 = 14 tables

Number of tables with 6 chairs = 0.65*40 = 26 tables

Therefore,

There are 14 tables with 8 chairs and 26 tables with 6 chairs in the cafe.

A runner warmed up for 10 minutes and then takes seven minutes to run each mile. The total time after r miles is 45 minutes how
scoundrel [369]
So our equation to find this can be represented by 7x + 10 = 45.
(x representing miles run)
Just solve for x!

Subtract the 10 from both sides, you've got
 7x = 35
And now to isolate the x, we divide both sides by 7.
Now we're left with just
x = 5!

We can check this by substituting 5 as x in our equation.
7x x 5 + 10 = 45
45 = 45
It's right!

So the runner ran 5 miles total.

Hope this helps!
If I skimmed over this too much, let me know and I'll try to explain the best that I can.

Find the equation of the line normal to the curve of y=3cos1/3x, Where x=\pi
sertanlavr [38]

Answer:

y = \frac{\sqrt{2}x}{3} - \frac{\sqrt{2}\pi}{3} + 1.5

Step-by-step explanation:

The equation to the line normal to the curve has the following format:

y - y(x_{0}) = m(x - x_{0})

In whicm m is the derivative of y at the point x_{0}

In this problem, we have that:

x_{0} = \pi

y(x) = 3\cos{\frac{x}{3}}

y(\pi) = 3\cos{\frac{\pi}{3}} = \frac{3}{2}

The derivative of \cos{ax} is a\sin{ax}

So

y(x) = 3\cos{\frac{x}{3}}

y'(x) = 3*\frac{1}{3}\sin{\frac{x}{3}} = \sin{\frac{x}{3}}

m = \sin{\frac{\pi}{3}} = \frac{\sqrt{2}}{3}

The equation of the line normal to the curve of y=3cos1/3x is:

y - y(x_{0}) = m(x - x_{0})

y - \frac{3}{2} = \frac{\sqrt{2}}{3}(x - \pi)

y = \frac{\sqrt{2}}{3}(x - \pi) +  \frac{3}{2}

y = \frac{\sqrt{2}x}{3} - \frac{\sqrt{2}\pi}{3} + 1.5

Three consecutive integers are such that three times the smallest is 14 more than the largest.Find the integers.
viktelen [127]

Answer:

<h3>           8, 9, 10</h3>

Step-by-step explanation:

x ← the smallest integer

x+1 ← the middle integer

x+2 ← the largest integer

3x   ← three times the smallest

x+2 + 14   ← 14 more than the largest

  3x = x+2 + 14

   -x     -x

  2x = 16

 ÷2     ÷2

   x = 8

x+1 = 8+1 = 9

x+2 = 8+2 = 10

Check:  3×8 = 24;  24-14 = 10
