A bag of candy contains 300 pieces of which 28% are red.

Mathematics

Answer:

216 candies are not red

Step-by-step explanation:

300 = Total candies

28% = Percent of candies that are red

100% - 28% = 72%  

72% = Percent of candies that are NOT red

My personal preference for setting up this type of question:

300 -> 100% (Total candies)

___ -> 72% (NOT red candies)

___ -> 28% (Red candies)

Next:

28% = 0.28

300 x 0.28 = 84

84 = Number of candies that are red

300 -> 100% (Total candies)

___ -> 72% (NOT red candies)

84   -> 28% (Red candies)

Now:

300 - 84 = 216

300 -> 100% (Total candies)

216 -> 72% (NOT red candies)

84 -> 28% (Red candies)

216 equals the number of candies that are NOT red.

Answer:

84 are red, 216 are non red

Step-by-step explanation:

if the bag has 300 pieces, then that's 100% of the sum of red + non red candies

28/100 x 300 = 84 are red

300 - 84 = 216 are non red

Solve the equation using the zero-product property. (2x − 8)(7x + 5) = 0 x = –2 or x = 7 x = 4 or x = x = 4 or x = x = –4 or x =
aliya0001 [1]

(2x-8)(7x+5)=0\iff2x-8=0\ \vee\ 7x+5=0\\\\2x-8=0\qquad\text{add 8 to both sides}\\2x=8\qquad\text{divide both sides by 2}\\\boxed{x=4}\\\\7x+5=0\qquad\text{subtract 5 from both sides}\\7x=-5\qquad\text{divide both sides by 7}\\\boxed{x=-\dfrac{5}{7}}

Find the unknown length of the right triangle. If necessary approximate the length to the nearest thousandth
WARRIOR [948]

We are given a right triangle and we are asked to determine the hypotenuse given the measure of its sides. To do that we will use the Pythagorean theorem:

h^2=(10km)^2+(20km)^2

Now, we solve the square:

h^2=100km^2+400km^2

Now, we add the values:

h^2=500km^2

Now, we take the square root to both sides:

h=\sqrt[]{500km^2}

Solving the operations:

h=22.361km

Therefore, the length of the hypotenuse is 22.361 kilometers.
