Answer:
9.73 lb
Step-by-step explanation:
The total together is 235.68 lb. Taking away the weight of the table, 157.84, we are left with
235.68-157.84 = 77.84 for the weight of all of the chairs. Dividing this by 8 gives us the weight of one chair:
77.84/8 = 9.73
Add the 2 equations together
y = -x+1
y =3x+1
========
2y = 2x+2
divide by 2
y = x+1
y = x+1
y = -x+1
======= add these two equations together
2y = 2 divide by 2
y = 1
y = x+1
1 = x+1
x=0
3x+y=3(0) +1=1
Answer =1
Answer:

Step-by-step explanation:
we know that
The roots of the quadratic function (x-intercepts) are
x=-1 and x=5/3
so
we can write the equation of the parabola as

where
a is a coefficient
Remember that
The parabola pass through the point (5,40)
substitute the value of x and the value of y of the ordered pair in the quadratic equation and solve for a
x=5, y=40



substitute

apply distributive property

Answer:
r = 1 ft
Step-by-step explanation:
Using the formula
d=2r
Solving for
r = d/2 = 2/2 = 1 ft
