A gold, a silver, and a bronze medal are awarded in an Olympic event. In how many possible ways can the medals be awarded for a 200-meter sprint in which there are 12 runners
Answer:
The medals can be awarded in 1,320 possible ways.
Step-by-step explanation:
Given that a gold, a silver, and a bronze medal are awarded in an Olympic event, to determine in how many possible ways can the medals be awarded for a 200-meter sprint in which there are 12 runners, the following calculation must be performed:
12 x 11 x 10 = X
12 x 110 = X
1,320 = X
Therefore, the medals can be awarded in 1,320 possible ways.
Which value is closest to the perimeter of the window
Answer:
9.82 feet
Step-by-step explanation:
the perimeter of the window is the circumference of a semi-circle with a diameter of 5
P = (πd)/2 (divided in half because it's only half a circle)
P ≈ 3.14(3.5) which is approx 11
11 is closest to 9.82
Answer:
9.82 Is the Closest
Step-by-step explanation:
First of all, you can see its a half circle, meaning if we make it a full circle, the length of the center is 5, so the full circle's area is about 19.5-20. Now to find the area of the half circle/windows we get 9.75 - 10. The only number between that is 9.82, which should be you answer.
Have a nice day!

Steven bought 4 pizzas to share with his family. Together, they ate 2 7/12 pizzas on Friday and another 2/3 of a pizza on Saturday. How much pizza is left??
Answer:
3/4 of a pizza is left.
Step-by-step explanation:
4 pizzas minus (2 and 7/12 plus 2/3). Change 2/3 to 8/12 by multiplying the numerator and denominator by 4 to get both denominators the same. 4 pizzas minus (2 and 7/12 plus 8/12 or 2 and 15/12 or 3 and 3/12 or 3 and 1/4). Restated 4 pizzas minus 3and 1/4 pizzas 3/4 pizzas. 3/4 of a pizza is left.

Suppose you have a deck of 52 cards. Let:
A: draw a 7
B: draw a diamond
Find the probability of A U B and write as a fraction
Answer:
16/52
Step-by-step explanation:
A U B= A + B - A ∩ B
A= 4/52
B= 13/52
A∩B= 1/52 (it's 1/52 because there is only one 7 of diamonds in the deck)
4/52+13/52-1/52= 16/52

What is the value of t? Points D and E are midpoints of the sides of triangle ABC. The perimeter of the triangle is 48 units. 2 3 B 6 8 D 37 А 4t 7t + 6 С
Answer:
2
Step-by-step explanation:
A midpoint divides a segment in two equal segments
DB = 3t
AB = 6t
BE = 4t
BC = 8t
8t + 6t + 7t + 6 = 48
21t = 42
t = 2
The value of t in the given triangle is 2.
What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
ABC is a given triangle.
The points D and E are the midpoints of the triangle ABC.
The perimeter of the triangle is 48 units.
We know that a midpoint divides a segment in two equal segments.
The midpoint is the middle point of a line segment.
DB = 3t
AB = 6t
BE = 4t
BC = 8t
From perimeter definition the sum of the sides is the perimeter.
8t + 6t + 7t + 6 = 48
Add the like terms
21t = 42
Divide both sides by 21
t = 2
Hence, the value of t in the given triangle is 2.

Solve the following quadratic by
completing the square.
y = x2 + 2x – 6
x =
[?]+)
Answer:
x = - 1 ± [tex]\sqrt{7}[/tex]
Step-by-step explanation:
let y = 0
x² + 2x - 6 = 0 ( add 6 to both sides )
x² + 2x = 6
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(1)x + 1 = 6 + 1
(x + 1)² = 7 ( take the square root of both sides )
x + 1 = ± [tex]\sqrt{7}[/tex] ( subtract 1 from both sides )
x = - 1 ± [tex]\sqrt{7}[/tex] , that is
x = - 1 + [tex]\sqrt{7}[/tex] , x = - 1 - [tex]\sqrt{7}[/tex]

Explain how a piece of food when eaten is digested and absorbed by the human body
PLS HURRY I NEED IT!!<3
Answer:
The muscles of the small intestine mix food with digestive juices from the pancreas, liver, and intestine, and push the mixture forward for further digestion. The walls of the small intestine absorb water and the digested nutrients into your bloodstream.
Answer & Explanation:
When humans chew food, it is chemically and physically broken down into smaller molecules. Your teeth physically crush the food and enzymes in your saliva break down the food into smaller pieces. Then your food goes through your esophagus and begins the digestion process. When the food reaches the stomach, the stomach walls pound the food to make it into smaller chunks of food. Hormones secreted in the stomach walls release acids and enzyme juices that chemically dissolve the food into even smaller pieces. The liver, pancreas, and gallbladder are major parts of the digestive process as well. They produce digestive juices and transfer bile to prepare for the next stage. After the food has been in the stomach for three hours, the food is now a liquid called chyme and is ready to move into the small intestine! The liver sends the bile to the gallbladder that secretes it into the duodenum. Then it dissolves the fats in the chyme so they can be digested by the juices from the pancreas and intestines. The enzyme juices break down the fat molecules in the chyme into fatty acids. The enzymes carry out the final deconstruction of proteins into amino acids. This happens in the small intestine lower region that is coated with villi. The villi maximizes molecule absorption and transfers it into the bloodstream. The blood then feeds it to the body’s organs and tissues.
That is whole process of digestion. Hope this helps! :3

Answer:
substitute the value of y into the equation 7x+3y = 35
7x + 3(x+5) = 35 (distribute 3 through the parenthesis)
7x + 3x + 15 = 35
collect the like terms
7x + 3x = 35 - 15
10x = 20 (divide both sides by 10)
x = 2
substitute x = 2 into the equation y = x + 5
y = 2 + 5
y = 7

when a number is doubled andthen eight added it became 60 what is the number
Answer:
26
Step-by-step explanation:
All I did was 60-8
(52)
Then 52/2
26
Answer:
26
Step-by-step explanation:
1) A number is doubled. This number will be represented by X.
8 + (X • 2) = 60
2) Subtract 8 from both sides of the equation
(X • 2) = 60 - 8
3) Simplify the equation
X • 2 = 52
4) Divide each side of the equation by 2
X = 52 ÷ 2
52 ÷ 2 = 26
5) Simplify the equation
X = 26
