Answer:
You must pick at least 13 pennies to be sure of getting at least five from the same year.
Step-by-step explanation:
You have:
12 1967 pennies
7 1868 pennies
11 1971 pennies.
how many must you pick to be sure of getting at least five pennies from the same year?
This value is the multiplication of the number of different pennies by the antecessor of the number of pennies you want, added by 1.
So
You have 3 differennt pennies
You want to get at least five from the same year.
You must pick at least 13 pennies to be sure of getting at least five from the same year.
For example, if you pick 12 pennies, you can have four from each year.
Adding three values, 13 is the smallest number that you need at least one term of the addition being equal or bigger than 5.
Answer:
1/2
Step-by-step explanation:
well, there are 10 cards altogether
then, count how many 5's there are.
there are 5.
therefore, 5/10 or 1/2
Idk tbh so I’m sorry guys lmso
Answer:
The value of the missing angle, x° is 115°
Step-by-step explanation:
The sum of the interior angles in a polygon is given by the formula (n - 2)×180, where, 'n', is the number of sides in the polygon
The number of sides in the given polygon, n = 10 sides
Therefore;
The sum of the interior angles in the polygon is (10 - 2)×180 = 1440°
The given angles of the polygon are;
107°, 126°, 325°, 125°, 95°, x°, 90°, 280°, 47°, and 130°
Therefore, we have;
107° + 126° + 325° + 125° + 95° + x° + 90° + 280° + 47° + 130° = 1440°
x° = 1440° - (107° + 126° + 325° + 125° + 95° + 90° + 280° + 47° + 130°) = 115°
The value of the missing angle, x° = 115°.
The answer is 5
Explanation:
We need to use the Pythagorean,
a^2 + b^2 = c^2
Where c is the hypotenuse
We can fill in spots now 12^2 + b^2 = 13^2
And then we solve 144 + b^2 = 169
Next we get b^2 alone
169-144=25
So we get b^2=25
For the final step you have to find the square root of 25 to get b alone which is 5
