If one inch is 60 then 3 would be 60*3 which is 180. The .5 s half of one so the half of 60 is 30. Add that to 180 and 180+30=210.
The answer is 210 miles
Answer:
Step-by-step explanation:
First, find the slope of the given line by finding two points. (0, 3) and (1, 1)
Use the equation for slope rise/run to find the slope.
From the left point to the right point, it goes down 2 units and to the right by 1 unit
-2/1 = -2 = slope
We already know the y-intercept which is y = 3, when x=0 and when the line crosses the y-axis
y=-2x+3 is the equation of the line.
Perpendicular line's slope is the opposite reciprocal of the original line's slope. Opposite reciprocal of -2 would be 1/2
y = 1/2(x)
y=1/2x -5/2
Answer:
17.922
Step-by-step explanation:
first you plug it in
y=0.860(17) + 3.302
then u simplify
y=14.62+3.302
then add them
y=17.922
Answer: 0.07 (choice B)
===================================================
Explanation:
Let's define two events: B = hitting bullseye, and, T = hitting the third (outermost) ring
To figure out the probabilities of each event happening, we need to find the areas of each region. The bullseye is a circle with radius 6 inches (half of diameter 12), so the area is roughly...
A = pi*r^2 = pi*6^2 = 36pi
The radius of the outermost circle is 6+5+5 = 16 inches, leading to an area of
A = pi*r^2 = pi*16^2 = 256pi
So P(B) = (36pi)/(256pi) = 9/64 is the probability of hitting bullseye
-----------------
The area of the third ring is equal to the difference of the overall largest circle and the second largest circle.
The second largest circle has a radius of 6+5 = 11 inches with area pi*11^2 = 121pi square inches
So the third ring has an area of 256pi - 121pi = 135pi square inches
P(T) = probability of hitting the third ring
P(T) = (135pi)/(256pi)
P(T) = 135/256
-----------------
The last thing to do is to multiply the two probabilities P(B) and P(T). This works because the two events B and T are independent
P(B and T) = P(B)*P(T)
P(B and T) = (9/64)*(135/256)
P(B and T) = 0.07415771484376
P(B and T) = 0.07
