I would say about 189 people. I found the percentage of 8 out of 11, which I rounded to the nearest tenth and got 73%. Since that is how much do carry brief cases, I took 100-73 and got 23% for those who don’t carry briefcases. Then I found 23% of 700, which is 189. So, 189 out of 700 people do not carry briefcases.
Answer:
less value
Step-by-step explanation:
To deterimine if value was improved or not, we need to compare the price reduction to the size reduction.
__
The reduction in price is ...
((new value)/(old value) -1) × 100%
= (42/50 -1) × 100% = -16%
The size reduction of 20% is more than the price reduction of 16%, so the chocolate bar is <em>less value</em>.
_____
<em>Additional comment</em>
Compared to the original value, the new price to chocolate ratio is ...
0.84/0.80 = 1.05
Effectively, the price was raised by 5%.
Here are your examples
A spring that is bouncing up and down.
An atom or molecule that resonates with a certain frequency.
In fact, anything that resonates: a violin string, a pendulum, the air column in a muffler,.....

Answer:
92
Step-by-step explanation:
x= the ideal mark for his third test
100 + 63 + x/3 = 85
163+x=85x3
163 + x = 255
x=92
He would need to get at least a 92 to have the 85 average.
