Answer: 58.11 cm³
Step-by-step explanation:
1. The volume can be calculated with the following formula:

Where <em>l</em> is the lenght, <em>w</em> is the width and <em>h</em> is the heigth of the smartphone.
2. You know that the dimensions are:

3. Convert the height and the width from inches to centimeters, as following:


4. Convert milimeters to centimeters:

4. Then, the volume is:

Answer:
She can type 225 words in 10 minutes
Step-by-step explanation:
We can find the rate by dividing the number of words by the time
90 words/ 4 minutes
22.5 words per minute
Now to find the number of words in 10 minutes, multiply the rate times the time
22.5 * 10 = 225
She can type 225 words in 10 minutes
Answer:
s = 4·3^t
Step-by-step explanation:
After the first term, each term in the sequence is 3 times the previous one. This is a description of a geometric sequence. Here, the first term is 4, so the general term is ...
an = 4·3^n . . . . for n counting from 0
We can name the function "s" for "speed" and use "t" for the time in seconds. Then the equation is ...
s = 4·3^t

Answer:
infinitely many solutions
Step-by-step explanation:
Let's eliminate the fractional coefficient in the first equation by multiplying that equation by 4:
4y = 6x - 4
The second equation can be rewritten as 4y = 6x - 4, so the two equations are actually identical. They have infinitely many solutions.
