Darren's model is wrong because he multiplied the fractions when he should have subtracted.
4/5 • 1/2 = 4/10

4/5 - 1/2
8/10 - 5/10 = 3/10

The correct model would be 3/10.

2 of the dozen eggs in a cartoon are cracked about what percent of the carton is not cracked
pychu [463]

well, a carton has a dozen, namely 12 or the 100%, two were cracked.

if we know 12 is the 100%, what is 2 off of it in percentage?


\bf \begin{array}{ccll}
amount&\%\\
\cline{1-2}
12&100\\
2&x
\end{array}\implies \cfrac{12}{2}=\cfrac{100}{x}\implies x=\cfrac{2\cdot 100}{12}\implies x=16.\overline{66}

A beach ball rolls off a cliff and onto the beach. The height, in feet, of the beach ball can be modeled by the function h(t)=64
Karolina [17]

Answer:

rate of change = -32 feet/second

Step-by-step explanation:

h(t) = 64 – 16t2

t = time (seconds)

Look at the start of time where t = 0

h(t) = 64 - 16 * (0) * 2 = 64 feet

Then look at the specified time where t = 1.25 seconds

h(t) = 64 - 16 * (1.25sec) * 2 = 24 feet

rate of change = rate of change y / rate of change x

x = time, y = height

rate of change = (24 - 64) / (1.25 - 0) = -32 feet/second

s2008m [1.1K]
Do a proportion
60/100= x/54

Cross multiply and divide
54 x 60= 3,240
3,240 divided by 100 is 32.4

Now subtract
54- 32.4= 21.6
