In the parking lot there are 1960 convertibles and 490 minivans, for a total of 2450 cars all together what is the ratio of cars
Sidana [21]

Answer: 5:4

Step-by-step explanation:

Given : The number of convertibles  = 1960

The number of minivans = 490

Total cars =  2450

The ratio of A to B can also be written as \dfrac{A}{B}.

The ratio of cars to convertibles = \dfrac{\text{Number of cars}}{\text{Number of convertibles}}

=\dfrac{2450}{1960}\\\\=\dfrac{5}{4}\ \ \ \text{[Simplest form]}

Hence, the  ratio of cars to convertibles = 5:4

A bowl is in the shape of a hemisphere (half a sphere) with a diameter of 8 inches. Find the volume of the bowl. Use 3.14 for pi
gayaneshka [121]

Answer: 267.947 (or 267.95) inches^3

Step-by-step explanation:

The formula for the volume of a sphere is \frac{4}{3}\pi r^{3}.

To find your radius (r), divide the diameter of 8 inches by 2. <em>The radius is 4 inches.</em>

Plug in your numbers to the volume equation to get \frac{4}{3} (3.14)(4^3). The first step is to cube 4 (4*4*4) to get <em>64</em>. Now your equation is \frac{4}{3}(3.14)(64).

Multiply 3.14 and 64 to get <em>200.96</em>. The equation is now \frac{4}{3}(200.96) or \frac{4}{3} * \frac{200.96}{1}.

Multiply the numerators (4 * 200.96) and denominators (1 * 3) to get a final equation of \frac{803.84}{3}.

Finally, divide 803.84 by 3 to get the final answer of 267.947 in^3.
