Answer: 25 houses
Step-by-step explanation:
Add the number of houses in each column.
Number of houses is shown on the left of the graph.
Let us say that y = vertical height and z =
hypotenuse <span>
dz/dt = 600
dy/dt = 0 since y (altitude) is constant
sin(θ) = 2/3
Calculating for the angle: θ = arcsin(2/3) = 0.729728 radians
sin(θ) = y/z
z sin(θ) = y
<span>We then differentiate the two sides with respect to time t:
dz/dt sin(θ)+ z cos(θ) dθ/dt = dy/dt
(600) (2/3) + (3) cos (0.729728) dθ/dt = 0
400 + [3 / cos (0.729728) ] dθ/dt = 0
400+ 4.0249 dθ/dt = 0
dθ/dt = -98.38 radians/hour
= -99.38/60 radians / min
= -1.66 radians / min = 2PI - 1.66 radians / min
<span>= 4.62 radians / min (ANSWER)</span></span></span>
Answer:
6.375 or 6 3/8
Step-by-step explanation:
Just add 2 2/3+1 5/6+1 7/8 and that= 6.375 or 6 3/8
It's a simple ratio table.
3 years 7 years 10 years
180 cm 368 cm
The difference between 3 and 7 is 4.
The difference between 180 and 368 is 188.
So every 4 years it increases 188 cm. A rate change of 4/188 simplify this fraction to be 1/47 so every 1 year it increases by 47 cm.
So 7 to 10 years is 3 years, so 47 x 3 = 141cm.
D. the median because its in the middle
