Answer:
The area of the actual playground is 
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared
let
z------> the scale factor
x------> the area of the actual playground
y-----> the area of the scale model of a playground
so
we have
substitute and solve for x
Answer:
Step-by-step explanation:
So, first lets the probability of just finding a yellow marble. There are 9+5+2+4 marbles in total, and that is 19 marbles.
5 out of those 20 are yellow, so the probabilty is 5/20 which is 1/4 or 20%
Then, lets do just finding the probability of a color that isn't blue.
Out of 20 marbles, 11 are color not blue, and 9 are.
So that probability is 11/20
Now, I think we need to do 11/20-5/20 so 6/20=3/10
Im so sorry, I might be wrong. I found both probabilities but I dont know if my final step is right.
Answer:
Step-by-step explanation:
steps are below
step 1
y^3-8y^2+19y=12 equation
step 2
y^3-8y2+19y(-12)=12(-12) minus 12 from both sides
y^3-8y^2+19y-12=0
step 3
(y-1)(y-3)(y-4)=0 add brackets
step 4
(y-1)(y-3)(y-4)=0 factor
step 5
y-1=0 or y−3=0 or y-4=0 set them equal
Answer:
y=1 or y=3 or y=4
