Are the ratios 30:12 and 40:16 equal if reduced?

serg [7]

Yes, borh ratios when reduced are 5:2. 30:12 is 5:2 because both are divisible by 6. 30/6=5 and 12/6=2. 40:16 is 5:2 because both are divisible by 8, 40/8=5 and 16/8=2

X^3 - 8 = x - 2 Solve the equation for all values of x

kirill [66]

X³-8=x-2: Original equation.
x³-x-6=0: Subtract x and add 2 to both sides.
(x-2)(x²+2x+3): Factor the equation
x-2=0; x²+2x+3=0: Separate the expressions into equations
x=2: Add 2 to both sides
x²+2x+3=0: Quadratic Formula
x= 2, -2+√-8,-2-√-8

It has been estimated that the price elasticity of demand for attending baseball games is 0.23. Other things held constant, a 10

Akimi4 [234]

Answer:

Correct option: (A) 43.48% fall in the price of a ticket.

Step-by-step explanation:

The price elasticity of demand is defined as the percent change in quantity demanded to the percent change in the price.

$Price\ elasticity\ of\ demand=\frac{\%\ change\ in\ quantity\ demanded}{\%\ change\ in\ price}$

Given:

Price elasticity of demand = 0.23

% change in quantity demanded = 10

Compute the % change in price as follows:

$Price\ elasticity\ of\ demand=\frac{\%\ change\ in\ quantity\ demanded}{\%\ change\ in\ price}\\0.23=\frac{10}{\%\ change\ in\ price}\\{\%\ change\ in\ price}=\frac{10}{0.23}\\=43.4783\\\approx43.48$

Thus, a 10 percent increase in attendance can be explained by a 43.48% fall in the price of a ticket.

Y is directly proportional to x^2, if y=9 when x=3, find: a) the constant of proportionality.

Gekata [30.6K]

Answer:

k = 1

Step-by-step explanation:

=> y ∝ x²

So, y = kx² ----------------------------(1)

Where k is the constant of proportionality

Now,

y = 9 when x = 3

Putting in (1)

=> 9 = k(3)²

=> 9 = k(9)

Dividing both sides by 9

=> k = 1
