Use the three steps to solve the problem. maple syrup worth $6.00 a gallon and corn syrup worth .80 cents a gallon are used to m

Ksenya-84 [330]

Cost of maple syrup = $6.00 a Gallon Cost of corn syrup = 0.80 cents a Gallon Cost of the syrup mixture = $2.36 a Gallon There is mixture of 50 Gallons Lets maple syrup be x gallons, so corn syrup be 50-x gallons Hence, 6*x + 0.80(50-x) = 2.36*50 6x + 40 - 0.8x = 118 5.2x = 78 => x = 78/5.2 => x = 15 So Maple will be syrup be 15 gallons. Corn syrup will be 35 gallons.

If y varies inversely with the square of r, what is the constant of proportionality when y - 10 and 1 = 5?

Anvisha [2.4K]

Question:

If y varies inversely with the square of r, what is the constant of proportionality when y =10 and r = 5?

Answer:

The constant of proportionality is 250

Solution:

Given that,

y varies inversely with the square of r

Which means,

$y \propto \frac{1}{r^2}\\\\y = k \times \frac{1}{r^2}$

Where, "k" is constant of proportionality

Subtitute y = 10 and r = 5

$10 = k \times \frac{1}{5^2}\\\\10 = k \times \frac{1}{25}\\\\k = 10 \times 25\\\\k = 250$

Thus the constant of proportionality is 250

Complete Question:

Emily and Zach have two different polynomials to multiply: Polynomial product A: (4x2 – 4x)(x2 – 4) Polynomial product B: (x2 + x – 2)(4x2 – 8x) They are trying to determine if the products of the two polynomials are the same. But they disagree about how to solve this problem.

Answer:

$A = B$
