C=2pir
a=pir^2
69.08=c=2pir
divide both sides by 2
34.54=pir
divide both sides by pi
34.54/pi=r
sub that

a=pir^2
a=pi(34.54/pi)^2
a=(34.54^2)/pi
a=(34.54)/3.14
a=379.94

area of rug is 379.94 square inches

What is the slope of the line parallel to 7x + 4y = -16?

GarryVolchara [31]

Answer:

The slope of the line that is parallel to the given line is $\frac{-7}{4}$

Step-by-step explanation:

Parallel lines have the same slopes and different y-intercepts

The slope of the line who has an equation ax + by = c is m = $\frac{-a}{b}$

Let us use these rules to solve the question

∵ The equation of a given line is 7x + 4y = -16

→ Compare it with the form of the equation above

∴ a = 7 and b = 4

∵ The slope of the line = $\frac{-a}{b}$

∴ The slope of the line = $\frac{-7}{4}$

∵ Parallel lines have the same slope

∴ The slope of the line that is parallel to the given line is $\frac{-7}{4}$

It is probably 0,2,4,6 because other ones go "out of the sequence".

Hope this helps. :)

What is the area of this trapezoid? 175 in² 140 in² 129 in² 85 in²

aksik [14]

Area of trapezoid = (B1 + B2)h/2

B1 = 15 in. + 4 in. + 6 in. = 25 in.
B2 = 15 in.
h = 7 in.

Area = (25 in. + 15 in.)(7 in.)/2 = 140 in.^2
