Answer:
The ratio of the number of mangoes in the $3 stack to those in the $6 stack is 1 : 2
Step-by-step explanation:
Let the number of mangoes bought by the grocery store be n. Also let the number of mango sold for $3 in one stack be x and the number of mango sold for $6 in the second stack be y.
Therefore:
x + y = z (1)
Also, the mangoes was sold at break even price, that is the cost of the mango and the price it was sold for was the same. Therefore:
Cost of buying = Price it was sold for
The cost of the mango = 5z and the price it was sold for = 3x + 6y
3x + 6y = 5z (2)
Substituting z = x + y in equation 1
3x + 6y = 5(x + y)
3x + 6y = 5x + 5y
6y - 5y = 5x - 3x
y = 2x
x / y = 1/ 2 = 1 : 2
The ratio of the number of mangoes in the $3 stack to those in the $6 stack is 1 : 2
Answer:
C
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, - 1) and (x₂, y₂ ) = (- 1, 1)
m =
=
= - 2
Note the line crosses the y- axis at (0, - 1) ⇒ c = - 1
y = - 2x - 1 → C
The percentage off that the individual got off from his groceries is 5.09%
<h3>Calculating the percentage coupon on an item</h3>
Tax is the amount removed on a cost of an item. It is represented as a percentage.
Given the following parameters
total price of goods = $69.50
Discount = $3.54
<u>Determine the </u><u>percent off</u>
Percent off = discount/Total price * 100
Percent off = 3.54/69.50 * 100
Percent off = 354/69.50
Percent off = 5.09%
Hence the percentage off that the individual got off from his groceries is 5.09%

The sinusoid makes a complete oscillation (i.e. 360°) every 3 seconds. So, in one second it makes 1/3 of a turn, leading to 360°/3 = 120°.
So, the correct answer is the last one.
