Write the equation for a line that is perpendicular to the line y=2x-3 and passes through the origin

Answers

Determine the slope

Since the equation is already given in slope-intercept form, we'd assume that the slope is the coefficient of x.

2 is the slope

To write the equation in perpendicular form, change the slope to opposite-reciprocal.

2 opposite-reciprocal is -1/2

So, the equation would be y= -1/2x - 3

Answer:

y= -1/2x - 3

Dr. florenz needs 25 grams of salt for each student to do an experiment. she has 1.2 kilograms of salt on hand. she has a total of 128 students. how much more salt does she need?

Answers

First we solve for how much Dr. Florenz needs in total. So:
128 students * 25 grams = 3200 grams
Then we know that she has 1.2 kg or 1200 g (convert from kg into g)
Now, since she needs 3200, we subtract 3200-1200 to find how much she doesn't have, how much she needs. 
The answer is 2000 g or 2 kg

What is 60% of 30.00 when making a purchase for 30.00

Answers

The easiest way to find this is first finding 10% by taking a zero off before the decimal point of 30.
This leaves $3. In conclusion: 10% = $3. 
Multiply 3 x 6 so that 60% = $18! 

$18 is 60% of $30.00
18 is 60% of 30.
50 percent of 30 is 15 and sense 30 is 3x10 its easy you just need to add 3 more

How can you use the Pythagorean Theorem to solve real-world problems?You can use the Pythagorean Theorem to find missing ________ (angles or lengths) in objects that are_________. ( squares, right triangles, or equilateral Triangles)

Answers

You can use the Pythagorean Theorem to find missing lengths in objects that are right triangles.

What is Pythagorean Theorem?

The Pythagorean Theorem is a mathematical principle that relates to right triangles. It states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

You can use the Pythagorean Theorem to find missing lengths in objects that are right triangles.

The theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

By rearranging the formula, you can solve for the missing length when given the lengths of the other two sides.

This can be applied to real-world problems involving measurements of objects or distances, such as determining the length of a ladder needed to reach a certain height on a wall or calculating the distance between two points on a map.
