We know all the side lengths so can use law of cosines. a=90, b=55, and c=50.
2500=8100+3025-2(90)(55)cos(C)
cos(C)=.8712
C=arccos(.8712)=29.4 degrees
Step-by-step explanation:
= (11+13+14+15+18+20+23+26)/8
= 140/8
= 17.5
Answer:
he equation given in the exercise is:
Observe that highest exponent of the variable "x" is 2. Therefore, it is a Quadratic equation.
Therefore, making an exponent 1 instead of the exponent 2 would turn the given equation into a Linear function.
Step-by-step explanation:
Answer: 23
Step-by-step explanation:
Benches = x
4x + 3 = 5x - 2
x = 5
this equals that x = 5 because we put the unknown algebraic number on one side and the numerals on the other.
So if there are 5 benches then the number of children will be
4 * 5 + 3 or 5 * 5 - 2, which both equal 23.
Therefore, the answer to this question is 23 children
Well, if half of the garden's area is 10' x 12.5' (which is equal to 125 inches^2), then we add 125+125 which gets us 250 inches^2 .
