Answer:
Step-by-step explanation:
Pythagorean Theorem
c^2 = a^2 + b^2
a = 20
b = 15
c = ?
c^2 = 20^2 + 15^2
c^2 = 400 + 225
c^2 = 625 Take the square root of both sides.
√c^2 = √625
c = 25
The third side is 25 cm long.
The denominator of your probability is the total number of outcomes possible. the answer choice would be "D"
X is equal to 50 in this equation.
Answer:
Step-by-step explanation:
The variables are defined, so we only need to express the given relations. The total of the two quantities is 14.
x + y = 14
The sum of costs is $72. Totts are $8 each, so x of them will cost 8x. Elentines are $3 each, so y of them will cost 3y.
8x +3y = 72
Answer:
1/3n-3<6
Step-by-step explanation:
One third of a number: 1/3
3 is subtracted from 1/3 of a number n: 1/3n -3
Result is less than 6: less is represented with the symbol <. So, the result of the expression 1/3n-3 is less (<) than 6.
The final expression:
1/3n-3<6
