Answer:
1) (8,24)
2) (2,6); it represents how she walks 2 steps in 6 feet.
Answer:
4%
Step-by-step explanation:
we know that
The simple interest formula is equal to
where
I is the Final Interest Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
in this problem we have
substitute in the formula above
solve for r
Convert to percent
Round to the nearest whole percent

H = Tower Height = 320
W = Tower Width = 260
h = Model Height
w = Model Width
h = (1/500) * H = (1/500) * 320 = .64 feet
w = (1/500) * W = (1/500) * 260 = .52 feet
Now, we need to convert these measurements to inches.
There are 12 inches per foot.
Let x = height in inches and y = width in inches
The ratio below compares feet to inches
x / h = 12 in / 1 ft
y / w = 12 in / 1 ft
Plug in h and w, cross multiply, and solve for x and y, respectively.
x / .64 = 12 / 1
1 * x = .64 * 12
x = 7.68 in
y / .52 = 12 in / 1 ft
1 * y = .52 * 12
y = 6.24 in
Answer:
V = π /2 volume units
Step-by-step explanation:
Volume of y = √x bounded by y = x and y = 1
y = √x
limits of integration ( see Annex )
By simple inspection limits of integration are x = 0 to x = 1
or y = √x and y = x
solving these two equations
x = 0 y = 0 x = 1 y = ± 1
V = ∫ π*f(x)²*dx
V = π * ∫₀¹ x*dx = π * x²/2 |₀¹
V = π * (1/2) - 0
V = π /2 volume units
Answer:
no
Step-by-step explanation:
because if you multiply 60 times 2 you dont get 2 so it is not proportional
