I need the description of how to draw a parallel line and a perpendicular line.

1 answer:

5 0

How to Draw Parallel Lines:
1. Draw a straight line any length

2. Draw another straight line any length

(note : ensure the lines will never intersect)

They shall never horizontally or vertically.

How to Draw Perpendicular Lines:
1. Draw a straight line vertically

2. Draw a straight line horizontally

(note : length does not necessarily matter)

The two lines must cross at right angles to each other!!

With the parallel line instructions, simply just draw lines but, when given the slopes of two lines, you must get graphing paper or make your own, and graph it by plotting points and then getting a ruler and tracing it.

With the perpendicular lines it helps with showing a relation between situations along with given slopes. They shall intersect always and meet at a 90° angle. Use the equations and plot them then take a ruler and trace them and notice the intersection. Solve it yourself and see that the intersection and the answers you got are the same.

Jacoby followed a recipe that requires 2 cup for water four every 3 cups of flours. if he used 8 cups flours, how many cups of w

zmey [24]

Answer:

5 and 1/3 cups of water.

Step-by-step explanation:

Set up a proportion like this:

2:3 for the original recipe

Then a second proportion for the recipe Jacoby used:

w:8 (use w for the unknown water amount)

Set up an equation so that the proportions equal each other. It helps if you write them in fraction form:

$\frac{2}{3} =\frac{w}{8}$

Use cross multiplication to get the new equation:

8 x 2 (or 16) = 3w

Then, divide both sides by 3 to get the amount for w, or water, by itself:

5 and 1/3 = w

I hope this helps! ☺

naomis fish is 40 ml long her guinea pig is 25 cm long how much longer is her guinea pig than her fish

aliya0001 [1]

Answer:

the guinea pig is 21 cm longer

Step-by-step explanation:

fish = 40 mm

guinea pig 25 cm

convert the fish to cm

1 cm = 10 mm

40 mm * 1 cm/10 mm = 4 cm

guinea pig - fish

25 cm - 4 cm

21 cm

the guinea pig is 21 cm longer

6 times a number is 27 less than the square of that number. Find the positive solution.

Verdich [7]

Let x = your number.

6x = x^2 - 27. Subtract 6x from each side.

0 = x^2 - 6x - 27. Factor

0 = (x-9) (x+3). Set each term equal to zero

(x+3) = 0. Subtract 3 from each side.

x = -3. This is the negative solution.

(x-9) = 0. Add 9 to each side.

x = 9. This is the positive solution.
