75.25x + 3604 = 300.50x
300.50x - 75.25x = 3604
225.25x = 3604
x = 16
Both companies charged the same at 16 tons
first answer 16 tons
--------------------
300.50x = 300.50(16) = $4,808
both companies charged the same are $4,808
second answer is $4,808

OK, With the ones I have gotten full answers on, the pattern is y=x-12
So, ? one is 6 because you ADD 12.
? 2 on the y side is -22 because you subtract 12!

a recipe calls for 6 cups water and 4 cups of flour.if the recipe is increased,how many cups of water should be used with 6 cups

fgiga [73]

The ratio is 6w = 4f.
Multiply both sides by 3/2 to get 6 cups of flour, and we have:
6*3/2 w = 4 * 3/2 f
18/2 w = 12/2 f
9 w = 6 f
So 9 cups of water.

A student is trying to calculate the density of a ball. She already knows the mass, but she needs to determine the volume as wel

mario62 [17]

<h2>Answer and Explanation:</h2><h2 />

The density of a substance is defined as its mass per unit volume. In a mathematical language, this can be written as follows:

$\rho=\frac{m}{V} \\ \\ \\ Where: \\ \\ \rho: \ density \\ \\ m:mass \\ \\ V:Volume$

From the problem, a student is trying to calculate the density of a ball. She already knows the mass, but is facing a problem because she also needs to find the volume. From geometry, we know that the volume of a sphere is:

$V=\frac{4}{3} \pi r^{3}$

Since a ball is a sphere, then the student can use this formula. She just need to measure the radius of the ball and compute the Volumen, then she have to plug both the value of the mass and the value of the Volume in the equation $\rho=\frac{m}{V}$ . An easy way to find the radius is to take the measure of the diameter of the ball and divide that value by 2.
