Im assuming that 100p is 1 pound? So that ratio should be A) 1:10 and 20mm is 2cm so the ratio is B)1:2
To answer, find the distance from point C to D, point D to E, point E to F, and point F to C. The formula for the distance is,
d = sqrt ((x2 - x1)² + (y2 - y1)²)
Point C to D d1 = sqrt ((-3 - -2)² + (1 - 4)²) = 3.16 units
Point D to E d2 = sqrt ((1 - -3)² + (0 - 1)²) = 4.12 units
Point E to F d3 = sqrt ((-1 - 1)² + (2 - 0)²) = 2.83 units
Point F to C d4 = sqrt ((-1 - -2)² + (2 - 4)²) = 2.23 units
Then, add up all the distances and the answer is 12.34 units. The closest answer is letter D. Credit:Meerkat
Answer:
There are no solutions to this equation because we will end up in 0=0 or if we do other methods, you will get something = 0
Hope it helps :)
Because of the low amount of dollars used, it is easier to use cents. 500 cents will buy you 250 text messages. You now need to find how much it cost to do one text message. Divide the price for 250 by the amount, and you will find that each text cost 2 cents. Now multiply by the 300 texts to find the total amount. 2 cents times 300 messages is 600 cents, or $6.
$6
Answer:
"a" must be negative
Step-by-step explanation:
The slope between points (-1, 1) and (1, -1) is a minimum of (-1-1)/(1-(-1)) = -1.
The slope between points (1, -1 and (3, -4) is a maximum of (-4-(-1))/(3-1) = -3/2.
Thus, as x increases, the slope is decreasing. In order for that to be the case, the value of <em>a</em> must satisfy a < 0.
