Answer:
666.6667 feet²
Step-by-step explanation:
So.
Since the scale is 1 : 20, we can do 4 x 20 and 5 x 20, Which is 80 and 100.
Find area: 80 x 100 = 8000 we can just add 2 zeros to 80 since it's multiplying by 100.
So it's 8000in²
Then we do 8000 in to feet.
Which is ≈ 666.6667feet
btw it asked for feet so we give them FEET

Answer:
probability of blue ball is 1/2
probability of yellow ball is 1/4
Step-by-step explanation:
We have given 6 blue balls 3 green balls and 3 yellow balls
Total number of balls are: 12
we have to find the probability of choosing a blue ball:
Then the ball was placed in the bag since, it is given replacement
Now, we have to find probability of choosing a yellow ball
{5x + 4y = -30
{3x - 9y = -18 | : 3
{5x + 4y = -30
{x - 3y = -6 | + 3y
{5x + 4y = -30
{x = 3y - 6
{5(3y - 6) + 4y = -30
{x = 3y - 6
{15y - 30 + 4y = -30 | + 30
{x = 3y - 6
{19y = 0 | : 19
{x = 3y - 6
{y = 0
{x = 3 · 0 - 6
{y = 0
{x = -6
