Answer:
Pretty sure it's 17 ducks.
The correct answer is based on the information given, we can estimate by probability that there are approximately 9 ducks with red marks on the bottom out of the 150 ducks in the pool.
To estimate the number of ducks with red marks on the bottom, we can use the information given: out of 50 people playing the game, only 3 have won a small prize.
We can assume that the probability of winning a small prize is the same for each player, and that each duck is equally likely to have a red mark.
If only 3 out of 50 people have won a small prize, we can estimate that the probability of winning is approximately 3/50.
Let's denote the number of ducks with red marks as "x." The probability of winning a small prize can be represented as x/150 (since there are 150 ducks in total).
Setting up the equation:
x/150 = 3/50
To solve for x, we can cross-multiply:
50x = 3 * 150
50x = 450
Dividing both sides by 50:
x = 9
Therefore, based on the information given, we can estimate by probability that there are approximately 9 ducks with red marks on the bottom out of the 150 ducks in the pool.

In a triangle, its midsegment is (2x + 8) units long and its parallel side is (5x - 9) units long. How long is the midsegment?
Answer:
The midsegment is 58 units long.
Step-by-step explanation:
Midsegment Theorem:
It states that the length of the midsegment is half the length of the parallel side.
In this question:
Midsegment: 2x + 8
Parallel side: 5x - 9
Parallel side is double the midsegment. So, we use this to find x:
[tex]5x - 9 = 2(2x + 8)[/tex]
[tex]5x - 9 = 4x + 16[/tex]
[tex]x = 25[/tex]
Midsegment:
[tex]2x + 8 = 2(25) + 8 = 50 + 8 = 58[/tex]
The midsegment is 58 units long.

One angle of an isosceles triangle measures 70°. Which other angles could be in that isosceles triangle?
Answer:
Step-by-step explanation:
The total of all 3 angles in every triangle equals 180 degrees. An isosceles triangle has two side lengths equal and two angle degrees equal.
So you either have two angles with each having 70 degrees and the third angle is 40 degrees,
70 + 70 + 40=180
OR
One angle of 70 degrees and two angles that are 55 degrees each.
70 + 55 +55 =180
Answer:
Step-by-step explanation:The total of all 3 angles in every triangle equals 180 degrees. An isosceles triangle has two side lengths equal and two angle degrees equal. So you either have two angles with each having 70 degrees and the third angle is 40 degrees, 70 + 70 + 40=180OROne angle of 70 degrees and two angles that are 55 degrees each. 70 + 55 +55 =180

simplify using distributive law ;
1.) X n ( X n Y )
2.) ( X n Y ) u ( X n Y )
Answer:
X n Y , X n Y
Step-by-step explanation:
1) Use Associative law:
X n (X n Y) = (X n X) n Y
Idempotent law:
= X n Y
2) it is in the 'distributed' form, thus we need to reverse the distribution,
akin to 'factorization':
(X n Y) u (X n Y) = (X n (Y u Y))
which can be further simplified using idempotent law:
= X n Y

Mi-young is cooking kalguksu for a large family kalgusku is a korean soup with noodles. She makes two kinds of kalguksu,chicken and seafood.
Mi-young makes 24 cups of seafood kalguksu. This is 60% of the total kalguksu she makes
HELP I DONT PAY ATTENTION IN CLASS
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the ratio and percentages.
let's be the total kalguksu soup quantity be x
hence, 60% of x = 24 cups, so we get as
===> 60/100 * x = 24
=> 0.6*x = 24
hence, x ==> 24/0.6
=====> x = 40 cups
hence the answer is 40 cups are in total kalguksu soup.

Answer:
106.83ft
Step-by-step explanation:
29 + 29 + 19 = 77ft
Now we must calculate the semicircle, The diameter is 19ft
19ft x 3.14 = 59.66
since 59.66 would be a full circle, you divide it in half.
59.66/2=29.83
