Suppose you bought 20 tickets in a drawing for a color television. There were 300 tickets sold in the drawing,

What is a square root and what does it do?

WINSTONCH [101]

Answer:

Hey

Definition:-

A square root is a number which produces a specific quantity when multiplied by itself.

Example:-

Suppose the area of a square of side 6 cm is given by 6 × 6 = 36 cm².

Therefore 36 is said to be the square of 6. We write 6² = 36 and we read the ‘the square root of 6 is 36' or simply ‘6 squared is 36.'

hope this helps

One u.s. fluid gallon contains a volume of 231 cubic inches. how many liters of gasoline would you have to buy in canada to fill

denis23 [38]

For this problem, we are asked to convert from one unit to another unit so we need conversion factors to be able to do this. We need to convert from gallon to cubic inches then from cubic inches to liter. We do as follows:

14 gallon ( 231 in^3 / 1 gallon ) ( 2.54 cm / 1 in )^3 ( 1 L / 103 cm^3) = 514.52 L

1. Determine whether the lines given by the equations 2x + 3y = and y=3/2x+4

son4ous [18]

Answer:

1. Yes, the lines are perpendicular.

2. $y=\frac{5}{4}x+6$

Step-by-step explanation:

The first equation of Exercise 1 is incomplete. Let's assume that it is:

$2x + 3y =n$

Where "n" is a number.

First, it is important to remember that the equation of a line in Slope-Intercept form is:

$y=mx+b$

Where "m" is the slope and "b" is the y-intercept.

By definition, the slopes of perpendicular lines are negative reciprocals.

1 . If you solve for "y" from the first equation, you get:

$2x + 3y =n\\\\3y=-2x+n\\\\y=-\frac{2}{3}x+\frac{n}{3}$

You can identify that the slope is:

$m=-\frac{2}{3}$

The second equation of the line is:

$y=\frac{3}{2}x+4$

And its slope is:

$m=\frac{3}{2}$

Since the slopes are negative reciprocals, the lines are perpendicular.

2. Given the first equation of the line:

$y= -\frac{4}{5}x+6$

You can identify that:

$m=-\frac{4}{5}\\\\b=6$

Since the first line and the second one are perpendicular, you know that the slope of the other line is:

$m=\frac{5}{4}$

According to the information given in the exercise, both lines have the same y-intercept; therefore, the equation of the second line is:

$y=\frac{5}{4}x+6$

You saw on the previous page that 2/11=0.18. Show how you can use what you know about the decimal for 2/11 to find the decimal f

pantera1 [17]

1/11 is half of 2/11. (1/11 + 1/11 = 2/11)

As 2/11 = 0.18, 1/11 must equal half of 0.18.

Half of 0.18 is 0.09. Thus the decimal for 1/11 is 0.09.
