Ebecca reads a book at a rate of 1 page every 4 minutes. If her reading rate remains the same, which method could be used to det

Nikolay [14]

Answer:

Multiply 4 by 16

Explanation:

Given

$Rate = 1\ page/4\ minutes$

Required

Select the method that maintains her rate for 16 pages

To get the method for 16 pages, we simply multiply 4 by 16. This is shown below

$Rate = 1\ page/4\ minutes$

Calculate the unit rate

$Rate = \frac{1}{4} page/min$

$Rate = 0.25 page/min$

For 16 pages, it is:

$Rate = \frac{16 page}{4 min * 4}$

$Rate = \frac{16 page}{4 min * 16}$ -- Here, we multiply 4 by 16

$Rate = \frac{16 page}{64\ min}$

$Rate = \frac{16}{64} page/min$

$Rate = 0.25 page/min$

See that the unit rates remain the same.

Other options will give different rates

The algorithm below simulates rolling a regular 6-sided die twice. Consider the goal of determining if the sum of the values of

FrozenT [24]

Algorithms are used to simulate real programs.

The true conditions of the algorithm are:

(a) If the value found in step 6 is 10, 20, 30, 40, 50 or 60 then the sum is even
(b) If the last digit of the value found in step 6 is 5, then the sum is odd

First, we analyze the algorithm.

Assume the outcomes of the two rolls are x and y

Step 4: Calculate sum

$Sum = x + y$
