Answer 1
Answer:

Final answer:

The correct statement is B. A vertical line has a slope of zero.

Explanation:

The correct statement is option B: A vertical line has a slope of zero. A slope of zero means that there is no relationship between x and y. Graphically, the line is flat, with zero rise over the run. A vertical line goes straight up or down and has no change in the x-coordinate, resulting in a slope of zero.

For Example: Consider the equation x = 2. This represents a vertical line that passes through the point (2, y) for any value of y. Since the x-coordinate does not change, the slope is zero.

Answer 2
Answer:

Answer:

A line that rises from left to right has a positive slope

Step-by-step explanation:

Verify each statement

case A) A horizontal line has no slope

The statement is False

Because a horizontal line has a slope equal to zero

case B) A vertical line has a slope of zero

The statement is False

Because a vertical line has a undefined slope

case C) A line that rises from left to right has a positive slope

The statement is True

case D) A line that falls right to left has a negative slope

The statement is False

Because a is a positive slope

Brass is an alloy made from copper and zinc in the ratio 3:2, based on weight. If 120g of copper are needed for a certain piece of brass, how much zinc will be needed for the same piece?

Answers

If 120g of copper are needed for a certain piece of brass, then the weight of the zinc that will be needed for the same piece is 80 grams.

What is a Ratio?

A ratio expresses the number of times one number contains another. For example, if a dish of fruit contains eight oranges and six lemons, the orange-to-lemon ratio is eight to six. Similarly, the lemon to orange ratio is 6:8, while the orange to total fruit ratio is 8:14.

Given that Brass is an alloy made from copper and zinc in the ratio 3:2, based on weight. Therefore, the ratio of the metals can be written as,

Copper / Zinc = 3/2

Now, as the weight of the copper is 120grams. Therefore, the ratio can be written as,

Copper / zinc = 3/2

120 grams / zinc = 3/2

zinc = (120 grams × 2) / 3

zinc = 80 grams

Hence, If 120g of copper are needed for a certain piece of brass, then the weight of the zinc that will be needed for the same piece is 80 grams.
