The Cartesian coordinate system is also known as a rectangular coordinate system and it is done on two coordinate axes that are perpendicular to each other.

<h3>What is a distance-time curve?</h3>

The distance-time curve can be plotted on the rectangular coordinate axis with distance on the y-axis while the time will be on the x-axis. The slope of the s-t curve gives velocity while v-t curve will give acceleration.

In the rectangular coordinate system, the points are of the form (x,y) but in the case of polar coordinates, the point on the circle will be denoted by (rcosθ,rsinθ) where 'r' is the radius of the circle.

Step-by-step explanation:

2 male percussionists

2 female percussionists

3 male woodwinds

2 female woodwinds

4 male brass players

3 female brass players

We're looking for a female woodwind. Now there is only 2 of them so we get the female woodwinds out of all the jazz band members or $\frac{2}{16}$ or $\frac{1}{8}$ or 12.5% chance.

Match the fraction with its equivalent decimal form of the number.

bagirrra123 [75]

Answer:

see below

Step-by-step explanation:

The overbar on decimal digits means they repeat forever.

Any fraction with a denominator consisting of powers of 2 and/or 5 will terminate. These can be converted to decimal by multiplying the fraction by a number to make the denominator an appropriate power of ten.

1 2/3 = 1.66666666666... repeating

1 3/5 = 1 (3·2)/(5·2) = 1 6/10 = 1.6

1 1/4 = 1 (1·25)/(4·25) = 1 25/100 = 1.25

1 33/50 = 1 (33·2)/(50·2) = 1 66/100 = 1.66

Of course, your calculator can tell you the decimal equivalents, too.
