The Country Buffet restaurant has tables that seat 6 people and booths that can seat 4 people. The restaurant has 38 seating uni
Alina [70]

Answer:

There are 20 booths and (38 - 20), or 18, tables

Step-by-step explanation:

Represent the number of tables with t and the number of booths with b.

We need to find the values of t and b.

(6 people/table)(t) + (4 people/booth)b = 188           (units are "people")

t + b = 38                                                                      (units are "seating units")

Solving the second equation for t, we get 38 - b = t.

Substitute 38 - b for t in the first equation:

(6 people/table)(38 - b) + (4 people/booth)b = 188

Then solve for b:   6(38) - 6b + 4b = 188, or:

228 - 2b = 188, or 2b = 228 - 188, or 2b = 40.  Thus, b = 20   (booths)

There are 20 booths and (38 - 20), or 18, tables.

Skee ball is a game played by rolling a wooden sphere up a ramp into a series of rings. The wooden ball has a surface area of ab
SVEN [57.7K]

<u><em>Answer:</em></u>

Radius of the ball is approximately 6.5 cm to the nearest tenth

<u><em>Explanation:</em></u>

The ball has the shape of a sphere

<u>Surface area of a sphere can be calculated using the following rule:</u>

Surface area of sphere = 4πr² square units

<u>In the given problem, we have:</u>

Surface area of the ball = 531 cm²

<u>Substitute with the area in the above equation and solve for the radius as follows:</u>

531 = 4\pi r^2\\ r^2=\frac{531}{4\pi } = 42.255 \\ \\ r=\sqrt{42.255}=6.5004 cm which is approximately 6.5 cm to the nearest tenth

Hope this helps :)

How do you solve for 5/6w = 2/3 (the answer is w= 4/5) I just don’t know how to show it.
Readme [11.4K]

Answer:

5/6w=2/3

5/6(4/5)=2/3

20/30=2/3

20/30=10/15=2/3=2/3

Proof:

5/6w=2/3

6/5*5/6w=2/3*6/5

30/30w=2/3*6/5

w=12/15=4/5

Hope this helps ;) ❤❤❤
