Part A: Find a rational number that is between 7.7 and 7.9. Explain why it is rational. (2 points)

1 answer:

7 0

Part A.
7.8 is a rational number between 7.7 and 7.9.
It is rational because it can be written as a fraction of integers, such as 78/10.

Part B.
sqrt(60) = 7.75
sqrt(60) cannot be written as a fraction of integers. It is a decimal number that never ends and never repeats.

Wittaler [7]

Answer:

The size of the scale model is 60 centimeters.

Step-by-step explanation:

Given that the length of a boat is 10.8 m, and Boris buys a scale model of the boat whose ratio is 1 to 18, to determine the length of the scale model of the boat in centimeters the following calculation must be performed:

1m = 100cm

10.8 m = (10.8 x 100) = 1080 cm

1080/18 = X

60 = X

Therefore, the size of the scale model is 60 centimeters.

Hey 20 points for the first person to show work and answer this

Harrizon [31]

Step-by-step explanation:

First, the pizza is 18 inches in diameter, so

$d = 18$

and, because the radium is half of the diameter,

$r = 9$

<u>Note that the units are inches.</u>

Using the equation

$a = \pi r ^{2}$

where a is the area of a circle, we know that the area of the whole pizza is approx.254.5 square inches. Divide by 8 to find the area of 1/8 of a pizza. Each slice will have an area of approx. 32 square inches. For a precise result, the answer is

$a(s)= \frac{(\pi \times 9^{2})}{s}$

where a(s) is the area of a slice of pizza, and s is the total number of slices, given they are equal in size.
