Answer:
The quadratic equation is x^2 -12x -120 = 0
where x represents the length of the field
Step-by-step explanation:
We want to make an expression in terms of a quadratic equation;
Let the length of the field be x mm , then the width will be (x-12) mm
Mathematically , the area of the field will be L * B
Thus;
x * (x-12) = 120
That gives;
x^2 -12x = 120
x^2 -12x -120 = 0
A given angle measures 90°.. Then, note that the total measurement of the triangle is 180°... Subtract 180° by 90°, and the other angles must add up to 90°!
Good luck!
Answer:
A. x/4 = 12
Step-by-step explanation:
Alicia and 3 of her friends are 4 people in total. To find what they spent, you do 4 • 12 = x, which is the same as x/4 = 12
Answer:
-2; Inferior good
Step-by-step explanation:
Given that,
Initial Quantity = 10 boxes
New Quantity = 8 boxes
Percentage increase in Sally's income = 10%
Change in consumption:
= 8 boxes - 10 boxes
= - 2 boxes
Percentage change in quantity demanded:
= (Change in quantity demanded ÷ Initial quantity) × 100
= (-2 ÷ 10) × 100
= - 20%
Therefore,
Income elasticity of demand:
= percentage change in quantity demanded ÷ Percentage change in income
= - 20% ÷ 10
= -2
Inferior goods are generally have a negative income elasticity of demand which means that an increase in the income of the consumer will lead to reduce the quantity demanded for inferior good and vice versa.
Hence, the good is a inferior type of good.
4x+4(3)+4(2)=y
4x+20=y
X equals the amount it cost for each ticket which is unknown. Y equals the total cost. Because the amount of the food is provided, it can be calculated unlike the tickets which is just left at 4x. The work for the snacks are upwards. Its mostly substitution.
