Answer: 150 students walk to school
Step-by-step explanation: 75%=0.75
200 multiplied by 0.75
200×0.75=150 students
Or
75%=3/4
3/4 of the children walk to school
3/4×200=3/4×200/1=150
Answer:
There were 7 small boxes and 14 large boxes shipped.
Step-by-step explanation:
This problem may be solved by a system of equations:
I am going to say that:
x is the number of small boxes used
y is the number of large boxes used
There were twice as many large boxes shipped as small boxes shipped
This means that 
Each small box of paper weighs 45 pounds and each large box of paper weighs 80 pounds. The total weight of all boxes was 1435 pounds.
This means that 
So we have to solve the following system:






There were 7 small boxes and 14 large boxes shipped.
Answer:
0.1905 = 19.05%
Step-by-step explanation:
We have a total of 106 containers of oxygen, from which:
20 have oxygen not ionized, 86 have oxygen ionized.
If the first one selected is ionized, now we have 20 not ionized and 85 ionized.
So the probability of the second one selected being not ionized is the number of not ionized (20) over the total number of containers (20 + 85):
P = 20 / (20 + 85) = 0.1905 = 19.05%
<u>D. 85 ((: </u>
40 + 55 = 95 then you would do 180 - 95 = 85
all triangle equal 180 ((:
