Tom and jasper have the same percentage of blue marbles in their bags of marbles. Tom had five blue marbles and 20 total marbles. jasper has 12 blue marbles. how many of jasper marbles are not blue?
Answers
First find the persentage of blue marbles 5/20 = 0.25 0.25 = 25%
Next find the persentage for the other marbles 100% - 25% = 75%
Now take 75% of Jasper's 12 marbles 12*0.75 = 9 marbles are not blue
How do i divide negative numbers
Answers
Divide normally but if you are dividing 2 negative number the answer will be positive but if you have a negative and positive number the answer will be negative
well for example if you have just 1 or and odd (1,3,5 etc.) amount of negitive numbers in the equation then you divide it normaly and then put a negitive sign in front of your answer. But if you have an even number of negitives, like 2, then you divide normaly and DO NOT add the negitive sign to your answer. (you can remember it if you think odd negitives=negitive and even negitives= positive)
ex. -9รท3 there is an odd number of negitives so you know the answer will be negitive so put a negitive sign to not forget. = -? then you forget about the signs and solve the equation. =3 then put it together and you get = -3
same for even amount of negitive numbers but you dont place the negitive sign and completly forget about negitives. good luck
A rectangular park has an area of 2/3 square mile. The length of the park is 2 2/3 the width of the park. What is the width of the park?
Answers
Area of the rectangular park = 2/3 square mile Let us assume the width of the rectangular park = x Then The length of the rectangular park = 2 2/3 * x mile = 8x/3 mile Then Area of the rectangular park = Length * Width 2/3 = (8x/3) * x 2/3 = 8x^2/3 (2 * 3)/3 = 8x^2 2 = 8x^2 x^2 = 2/8 x^2 = 1/4 x^2 = (1/2)^2 x = 1/2 So the width of the park is 1/2 feet.
