Answer:
%18.75
Step-by-step explanation:
360 is 11.25% of 3200. If you subtract 11.25 from 30, you get 18.75. So 18.75 percent of the townspeople speak only italian,
More in depth and another way to solve:
the 30% is the amount of people that speak italian. And that 30% is split into two groups. The people that ONLY speak italian. and the people that speak BOTH italian and french.
By doing a little calculation, you find out that 960 people in the town speak italian. 360 of these people also speak french. So in order to find the amound of people that ONLY speak Italian, subtract 360 from 960 to get 600. 600 people in the down ONLY speak Italian, and not french. 600 is 18.75% of 3200, so 18.75% of the townspeople speak only Italian
Did that make sense?
Hai, Brainiac!
Great question!
Basically to find the answer, first you add the number of each marble there is.
5 black marbles + 9 white marbles + 2 red marbles = 16 marbles altogether.
Red marbles to the total number of marbles altogether is 2:16, a ratio.
Simplified, that would be 1:8 marbles, or, answer choice B, so your answer would be 1/8 :D
Hope this helps!

Answer:
i.1832 ii.-56
Step-by-step explanation:
using BODMAS for the first question we solve for what's in the bracket after we go with the division and after multiplication next addition and subtract in doing all that we get
35+25*72-51/17
35+25*72-3
35+1800-3
1835-3
1832
you can also use your calculator to verify answer
