Answer:

1200 ounces

Step-by-step explanation:

How much of an alloy that is 10% copper should be mixed with 600 ounce of an alloy that is 70%copper in order to get an alloy that is 30%copper?

Let us represent

Number of ounce of 10% copper = x

Hence, our Equation =

x × 10% + 600 × 70% = (x + 600) × 30%

0.1x + 420 = (x + 600)0.3

0.1x + 420 = 0.3x + 180

Collect like terms

0.3x - 0.1x = 420 - 180

0.2x = 240

x = 240/0.2

x = 1200 ounces

Answer:

A.) What is your favorite subject this year?

Step-by-step explanation:

A statistical question is a type of question that can't be answered with just one number or value. It has to have different responses for different types of people in different situations. An example of a statistical question is "What do you do afterschool?" because every person does different things afterschool. The only question that has different responses for different people is the first one, "What is your favorite subject this year?".

What are the values of a and b?
aleksklad [387]

Answer: A

Step-by-step explanation: While I'm sure there is an equation to solve this which I don't remember I used process of elimination to solve this, there are two right triangle and one of the triangles is sides a, 2, and b. Since B is across from the right angle, it is the hypotenuse, therefore b is greater than a, that means d and b cannot be correct, since a is the same in a and c, we can assume a=8, using Pythagorean Theorem. 8^2 + 2^2= b^2.

b^2 = 68

the square root of 68 can be simplified to 2 * square root of 17

If g(x) and f(x) are inverse functions, which graph represents g(x)?
34kurt

When g(x) and f(x) are inverse functions, the graph that represents g(x) is the second graph.

<h3>How to explain the graph?</h3>

It should be noted that the first graph shows the radical expression where, f(x) = ✓x.

In order to find the inverse, we need to replace f(x) with y and switch the x. This will be:

x = ✓y

(✓y)² = x².

y = g(x) = x²

Therefore, the graph that shows the exponential growth is the second graph.
