45²
This says "forty five squared"
Try saying it aloud, it may help to hear it :)
This basically just means to multiply 45 by itself twice.
So, what's 45 times 45?
Its 2025!
Hope I helped! :)
A triangle is 180 degrees. Depending on their angles: Right Angle - 90 degrees
Acute Angle - less than 90 degrees and Obtuse Angle greater than 90 degrees and under 180 degrees. Hope that helps.
The function "choose k from n", nCk, is defined as
nCk = n!/(k!*(n-k)!) . . . . . where "!" indicates the factorial
a) No position sensitivity.
The number of possibilities is the number of ways you can choose 5 players from a roster of 12.
12C5 = 12*11*10*9*8/(5*4*3*2*1) = 792
You can put 792 different teams on the floor.
b) 1 of 2 centers, 2 of 5 guards, 2 of 5 forwards.
The number of possibilities is the product of the number of ways, for each position, you can choose the required number of players from those capable of playing the position.
(2C1)*(5C2)*(5C2) = 2*10*10 = 200
You can put 200 different teams on the floor.
The sum of two numbers is 136 (sum is what you get when you add two numbers together). If one of the two numbers is 51, and the other number is X, then:
X + 51 = 136
To solve for x we subtract both sides by 51.
X + 51 -51 = 136 - 51
X = 85
The other number is 85.
What are the common factors of these two numbers?
Factors are the numbers that multiply to make the product.
Factors of 51: 1, 51, 3, 17
Factors of 85: 1, 85, 5, 17
Only 1 triangle can be constructed with the given measurements.
