Find the area of a parallelogram with base 15 yards and height 21 2/3

icang [17]

Answer:

A = 325 yd^2

Step-by-step explanation:

The area of a parallelogram is found by multiplying the base times the height

A = bh

A = 15* 21 2/3

Changing the mixed number to an improper fraction

21 2/3 = (3*21+2)/3 = 65/3

A = 15 * 65/3 = 15/3 *65 = 5*65 =325

A = 325 yd^2

Answer:

1,600 dentists were surveyed in total.

Step-by-step explanation:

We can set up a proportion for this problem:

$\frac{27}{40} = \frac{1080}{x}\\\\\\$

Now we can cross multiply:

$27*x = 1080*40\\\\27x = 43,200\\\\27x/27 = 43,200/27\\\\x = 1,600$

1,600 dentists were surveyed in total.

Alright...so the coordinates of an ordered pair have opposite signs [one sign is positive while the other is negative] so we could have an example of (-x,+y) or (+x,-y) ...that means out of the 4 quadrants these points could be in the 2nd quadrant or the 4th quadrant or corners of the graph
