Answer:
230 2/3 ft
Step-by-step explanation:
60 5/6 + 54 1/3 + 59 1/3 +56 1/6
5/6+1/3+1/3+1/6=
Put them into same denominator times 1/3 by 2
5/6+2/6+2/6+1/6= 10/6 (this is improper fraction, simplify and then turn it into mixed)
10/6= 5/3 = 1 2/3
60+54+59+56= 229 +1= 230 and the 2/3 before makes it
230 2/3 ft
Answer:
12.6
Step-by-step explanation:
The two left sides have lengths, so this allows you to establish the ratio of the lengths of the sides of the triangles,
left triangle : right triangle
ratio = 25 : 17.5
The bottom sides are also in the same ratio.
ratio = 18 : w
Write a proportion by setting the ratios equal and solve for w.
25/17.5 = 18/w
Cross multiply.
25w = 17.5 * 18
25w = 315
w = 12.6
Answer: 12.6
Answer:
6
Step-by-step explanation:
really dude, im in 7th grade and answerd this.
ax^2 +bx+c=0
X^2 + 2x+8=0 so a=1, b=2, c=8
Discriminat= b^2 -4ac=2^2 -4•1•8=4-32=-28
So there are no real number solutions, yet there are complex numbers solutions.
Solutions=(-b+- sqrt (discriminant))/2•a
=(-2+-i sqrt ( 2•2•7))/2
Solutia 1= -1 + i sqrt7
Solutia 2= -1 - i sqrt 7
The equation of the graph show is
y = -2/3x - 2
