Answer:
1/4 and 0.25 and 25% chance for blue, 2/5 and 0.4 and 40% chance for red, and 7/20 and 0.35 and 35% for green.
Step-by-step explanation:
add all the marbles (20) and that’s the total. then however many marbles in the color that’s the top number in the fraction. divide the top number by the bottom number to get the decimal and move the decimal 2 spaces to the right to get the percent.
Answer:
Is not possible to compute the angle under those conditions.
Step-by-step explanation:
You need more information, I will be more specific, there is a book called "Geometry" by Moise Downs where the following theorem is stated on the chapter 7.
Let ΔABC and ΔDEF be two triangles where AB = DE and AC = DF if
∠A > ∠D then BC > EF, which in simple terms means that, if two sides are equal, the angle between them can vary as much as you want and that will directly imply the size of the third size of your triangle.
Therefore, there is information missing in order to solve the question
The first triangle does. That's the right answer.
-5- is the correct answer
Answer:
8 seconds
Step-by-step explanation:
lets first start by plugging in 1024 into initial height
h(t) = -16t^2 + 1024
I would find a Greatest Common Factor (GCF) first
-16(t^2 - 64) If this is new just think that if you multiply -16 by t squared and -64 you will come back to the original equation
But now we notice that T squared -64 can be factored with the difference of perfect squared method
so we will get -16(t-8)(t+8)
So to get the answers we will set everything equal to 0
-16t =0
t =0 this is the time that the penny was thrown
t-8 = 0
t = 8 the is the time the penny hit the ground
t+8 =0
t= -8 This is an extraneous solution or a solution that doesn't make sense so we just disregard the solution.
