The Paks bought 4 lunches for $16. The McGills bought 6 lunches for $24. The Manns bought 15 lunches for $60. The relationship o
f lunches to cost is a proportional relationship. What is the constant of proportionality? A. B. C. 4 D. 64
1 answer:
Answer:
$4
Step-by-step explanation:
The equation for direct proportionality =
y = bx
where y = dependent variable
b = constant
x = independent variable
There is positive proportionality is two variables are positively related to each other.
In this question, price of lunches is the dependent variable while number of lunches is the independent variable
$16 = b4
Divide both sides by 4 to find b
b = $4

Answer:266.8
Because you need to divide 1334÷5=(266.8)
It is that the angle has to be formed by two pairs of congruent/corresponding sides of the triangle
Ok so, 42 ft. by 42 ft.
$25 per square yard
1 square yard = 9 square feet
The total square footage is 1,764 ft.
Total square yards is 196.
The total cost would be $4,900.
There should be 283.9. (rounded to the nearest unit). :) <span />
