Using the Pythagorean theorem:
90^2 +90^2 = X^2
8100 + 8100 = x^2
16,200 = x^2
X = √16,200
X = 127.28 feet.
Rounded to the nearest foot = 127 feet.
Answer:
I think its C
Step-by-step explanation:
I think its y= -x+6 i think this because it would be a positive number or variable
x= 3+√5/4,3-√5/4
Step-by-step explanation:
1.In general, given ax^2+bx+c=0, there exists two solutions where:
x= -b+√b^2 - 4ac/2a, -b-√b^2-4ac/2a
2.In this case, a=4, b=-6 and c=1.
x=6+√(-6)^2-4×4/2×4, 6-√(-6)^2-4×4/2×4
3.Simplify.
x=6+2√5/8, 6-√5/8
4.Simplify solutions.
x=3+√5/4, 3-√5/4
The 3 over 8 because 1 over 4 is 25 from 100 but 3 over 8 do not tell how many she bought in all.there is no number multiply by 8 then gives as 100, ? × 8=100 but there is a number multiply by 4 then gives as 100 25 × 4=100 the answer of the question is '3 over 8'
