How can you tell Is something is a unit rate

Unit rate is a ratio between two different units with a denominator of one. When we divide a fraction's numerator by its denominator, the result is a value in decimal form. For example: 8/4 = 2 and 3/6 = 0.5. When we write numbers in decimal form, we can write them as a ratio with one as the denominator.

For example, we can write 2 as 2/1, and 0.5 as 0.5/1. However, since that approach can be a little clumsy, we usually drop the one. That said, it's important to remember the one is there, especially when working with unit rates.

For instance, 8 miles/4 hours = 2 miles/hour. Notice again that, while we did not include the 1, we did include the unit 'hour' Miles per hour is a familiar expression, as are unit rates such as:

interest/amount invested

revolutions/minute

salary/year

Conversationally, the word ''per'' indicates we are using a unit rate.

Help plz
LUCKY_DIMON [66]

Answer:

h = 0.64 ft

Step-by-step explanation:

s =  \frac{14 + 12 + 6}{2}  =  \frac{32}{2}  = 16 \: ft \\  \\ A =  \sqrt{(s - 14)(s - 12)(s - 6)}  \\  \\ A =  \sqrt{(16 - 14)(16 - 12)(16 - 6)}  \\  \\ A =  \sqrt{(2)(4)(10)}  \\  \\ A =  \sqrt{80}  \\  \\ A =  8.94427191\\  \\ A  \approx  8.94 \:  {ft}^{2}

A = 14h

8.94427191 = 14h

h = 8.94/14

h = 0.638571429

h = 0.64 ft

A is the poin 3,5 and b is the point 0,k if the distance of ab is 5 units find the possible value of k
JulijaS [17]

Answer:

K is either 9 or 1

Step-by-step explanation:

Sqrt((0 - 3)² + (k - 5)²) = 5

Square both sides

(0 - 3)² + (k - 5)² = 5²

(0 - 3)² + (k - 5)² = 25

-3² + (k - 5)² = 25

9 + (k-5)(k-5) = 25

9 + k² - 5k - 5k + 25 - 25 = 0

k² - 10k +9 = 0

k² - 9k - k + 9 = 0

k(k - 9) - 1(k - 9) = 0

k - 1 = 0 ; k = 1

k - 9 = 9; k = 1

K = 9 or k = 1

K is either 9 or 1
