Answer:
The constant of proportionality gives you the price per unit at each store.
Step-by-step explanation:
If you assume that the price (y) is directly proportional to the amount (x) you get, the formula is
y = kx
where k is the constant of proportionality.
k = y/x
k has the units of cost per unit, for example, dollars per ounce.
The fewer the dollars per ounce, the better the deal you are getting.
If store A offers apple sauce at $1.29 for 25 oz and Store B offers apple sauce at $2.89 for 50 oz, which is the better deal?
At store A, k = $1.29/25 oz = $0.052/oz or 5.2¢/oz
At store B, k = $2.89/50 oz = $0.058/oz or 5.8¢/oz
The apple sauce is cheaper at Store A.
Answer:
6.59999999999999999977 × 10^17
Step-by-step explanation:
6.6 x 10^17 - (9.2 x 10^14)/(4 x 10^16)
True… irrational numbers focus more around square roots that cant be simplified into a single number, or symbols like pi. while not all rational numbers are whole, an irrational number can never be whole.
Answer:
1,536 square centimeters
Step-by-step explanation:
The formula for the Lateral surface area of the pyramid =
1/2 × perimeter of the square base × slant height
Square base = 32cm
Slant height = 24cm
Perimeter of the square base = (4 × length of the square base side)
4 × 32cm = 128cm
Lateral Surface Area = 1/2 × 128cm × 24cm
= 1,536 square centimeters
