Answer:
15 cm
Step-by-step explanation:
The altitude is one leg of the right triangle formed by the altitude, half the base, and the triangle side. The Pythagorean theorem applies, so you have ...
... (17 cm)² = (altitude)² + (16 cm/2)²
... altitude = √(17² -8²) cm = √225 cm
... altitude = 15 cm
Answer:
Both of your answers are correct.
Step-by-step explanation:
Expand the equations by distributing the number outside of the parentheses. After doing the expansion, your equations are both correct.
Answer:
If:
(1)
And we have to rewrite the following expresion in terms of
:
(2)
Firstly we have to rearrange the right side of equation (2) in terms of
, factorizing by the common factor:
Then, we can substitute
by
:
And set it equal to zero:
>>>>This is the resulting equation
Now, each term of an algebraic expresion (like the equation above) is composed of sign, coefficient, variable and exponent. The terms are separated from each other by the plus sign (+) or the minus sign (-).
In this case, the variable is
and the number that multiplies the variable (the coefficient) is
, whereas the constant (which is the term with no variable) is 
Answer:

Answer:
29
Step-by-step explanation:
Sum of the 21 numbers is 21*30 = 630
Now let's remove 50 from the sum of 630
630-50 = 580
The new average can be found. Remember we removed the largest number so we now have 20 numbers.
580/20 = 29
