158 boys, and 163 girls, do this by dividing 321 by two(do get how many of each gender if #s were equal) subtract 2.5 to get boys, and add 5 to that to get girls
Answer:
yes because when you multiply 3000 by 10 that gives you a total of 30000 that you paid off
Answer:
Step-by-step explanation:
we have that
The scale drawing is
we know that
Using proportion find out the actual dimensions of the volleyball court
Let
x -----> drawing court lengths in cm
y ----> court lengths in cm
For x=40 cm
For x=80 cm
Find the equation for the proportional relation ship between drawing court lengths x in centimeters and court lengths in y centimeters
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form 
or 
For x=40 cm, y=900
substitute
-----> 
The equation is
Answer:
19/72
Step-by-step explanation:
To calculate the probability that a randomly-chosen child from this group likes either Chess or Swimming but not Football?
We already know the number that liked chess only which is 10, we have to solve for those that liked swimming only which is
8+7+16+x = 40
x which represent swimming only is
40-31 = 9
Thus probability = 10/72 + 9/72 = 19/72
7/50 = 0.14 therefore In order to write it as a fraction out of 100 you move 2 decimal to the right.
Therefore, the answer for the first box is 14/100
The last box obviously being 0.14
