Step-by-step explanation:

Complete Question

2columbia records unveiled the lp (a vinyl record) in the waldorf astoria on june 18, 1948, in two formats: 10 inches in diameter, matching that of 78 rpm singles, and 12 inches in diameter. if the thickness of one vinyl record is 0.112 in, then determine the difference in volumes between the 10 inch and 12 inch records.

Each of the vinyl records will be modelled as a cylinder

Volume of a cylinder = πr²h

For the 12 inches diameter records.

r = (12/2) = 6 inches

h = thickness = 0.112 inches

Volume = π × (6²) × 0.112 = 12.672 in³

For the 10 inches diameter records

r = (10/2) = 5 inches

h = thickness = 0.112 inches

Volume = π × (5²) × 0.112 = 8.8 in³

Difference in volume between the two vinyl records = 12.672 - 8.8 = 3.872 in³

Hope this Helps!!!

Max makes $612 every three months. At the same rate, how much does Max make in one year (12 months)?
Lostsunrise [7]
Ok! 

Lets find out how much he makes per month.

You do this by dividing 612 and 3. so 612 / 3 = 204.
Max makes 204 per month.

2. Now that you have the per month, you multiply it by 12. 

204 x 12 = 2448

Answer: 2,448

I hope this helped you understand!

A car travels 470.7 kilometers on 52.3 liters of gas. How much gas will it need to go 345.6 kilometers?
murzikaleks [220]

Answer:

38.4[litres].

Step-by-step explanation:

1. \ the \ rule \ \frac{470.7[km]}{52.3[l]} =\frac{345.6[km]}{x};

2. \ x=\frac{345.6*52.3}{470.7}=38.4[l].

Use SAS to explain why ABC = DBC.
sergij07 [2.7K]

Explanation:

The figure shows us ...

  AB ≅ DB

  ∠ABC ≅ ∠DBC

  CB ≅ CB

In order, these are Side, Angle, Side in one triangle being shown congruent to corresponding Side, Angle, Side in the other triangle. This lets us conclude that ...

  ΔABC ≅ ΔDBC by SAS

Two ants start at the origin of the rectangular grid shown above where each unit represents an inch. They roam around in differe
weeeeeb [17]
To help clarify the problem, we can plot the two ants on a graph (see attached image). However, we don't need the graph to solve the problem.

Let's first find the distance in their 'x' values:
= |-3| + |4|
The '| |' means that we don't care if it is negative, we just want the positive value.
= |-3| + |4| is the same thing as = 3 + 4
= 7

Now let's find the distance in their 'y' values:
= |5| + |-2|
= 7

From here, since we have the 'x' and 'y' distances, we can create a triangle. The 'x' and 'y' will be our side lengths, and the hypotenuse is then the distance between the two ants. 

In order to find the hypotenuse, we use the Pythagorean theorm: c^{2}=a^{2}+b^{2}

Now we plug and solve:
c^{2}=(7)^{2} + (7)^{2}
c^{2}=98
c= \sqrt{98}

∴The distance between the two ants is \sqrt{98} or 9.899

Hope this helps!
