Set up a proportion where number of times is on top and miles is on bottom:
6/1 = x/(5/6)
Cross-multiply:
6*(5/6) = 1*x
5 = x
She must run 5 times around her neighborhood.
Answer:
third option
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 2x - 5 ← is in slope- intercept form
with slope m = - 2
Given a line with slope m then the slope of a line perpendicular to it is
= - 
= - 
= 
, then
y = x + c ← is the partial equation
To find c substitute (- 1, 1) into the partial equation
1 = - + c ⇒ c = 1 + = 
y = x + ← equation of perpendicular line
The tank has the shape of a cone
So, the area of the cone = π r²+ π r s
where r is the radius
s is the slant height = √(r²+h²)
h is the height
given the diameter = 18 m and the height = 54 m
∴ r = 9 m , h = 54 m
∴ s = √(r²+h²)
= √(9² + 54²) = 54.745 m
∴ Area = π r²+ π r s
= π * 9² + π * 9 * 54.745 ≈ 1802.3 m²
The correct answer is the first option 1802 m²

Understanding how to solve...</h2>
The base of each triangle is 11 ft, and the height of it is 9 ft.
And then, there are 4 of these triangles. So, as we know, when we do the formula for finding one triangle, we do 
. But if we have to do it for 2, then we will do... 
, and applying that same trick, if we have to do it for 4 of them, we will do

209.66ft² of wrapping paper was used
Answer:
11/3
Step-by-step explanation:
x=1, R=39, y=?
R=6x + 9y
(substitute the parameters into the equation)
39=6(1) + 9y
39= 6 + 9y
(collect like terms)
39 - 6 =9y
33=9y
(divide both sides by 9)
33/9=9y/9
11/3=y
therefore, y= 11/3
