Write down the equations you know!
40x + 60y = 6500
x = 5y
x = bootcut jeans
y = straight leg jeans
Replace 'x' with it's equation, then solve for y.
40(5y) + 60y = 6500
200y + 60y = 6500
260y = 6500
y = 25
Now plug that back into one of the original equations:
x = 5y
x = 5(25)
x = 125
125 = bootcut jeans
25 = straight leg jeans
Answer:
3
Step-by-step explanation:
volume of a hemisphere = (2/3) x (n) x (r^3)
n = 3.14
r = radius = 12/2 = 6
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
(2/3) X (6^3) X 3.14 = 452.16 cm^3
1 cm = 1 gram
452.16g
So we see Model/actual so for the first question, it would be n/48 = 1/40. 40n = 48. n = 1.2. Next question 4.3/n = 1/38. n = 4.3(38) = 163.4.
We are going to use exponential function. The population growth is mostly formulated as
P = P₀b^(kt)
where
P₀ = initial population
b = base number
k = proportionality constant
t = time
Given P₀ = 64. The base number is increased by 50%, in this case, 1+0.50=1.50. Yet every four hours, this will be proportionality constant. Pluging in the values, we have the function:
P = 64(1.50)^(4t)
