the height of the poster must be multiplied by the ratio which is 1 to 2.5 which is 40 cm.
Answer:5
Step-by-step explanation:there are 6 boxes between the top of the 3rd box and the bottom of the 10th box.
Since each box is 10 inches tall, the length of the 6 boxes sum up to 60 inches.
and since 12 inches =1 feet,
Then 60 inches = 5 feet
How to solve
Let "y" = the unknown number of feet's
12 inches = 1 feet
60 inches = y
Cross multiply
> 12×y =60×1
> 12y =60
Divide both sides by 12 since you want the value of "y".
> 12y÷12=60÷12
So 12 cancels out leaving the final answer to be:
> y=5
Answer: a) y=-29x-20 b) y=3/5x-18
Step-by-step explanation:
a) m = (-49-38)/(1 - (-2)) = -87/3 = -29
y=-29x+b --> Substitute (1,-49) as a point
(-49)=-29(1)+b
-49=-29+b
-b=-29+49
b=-20
Therefore, the equation of the line is y=-29x-20
b) m = (-18-(-9)/(0-15)) = -9/-15 = 3/5
The y-intercept is (0,-18) as it's where the line intersects the y-axis and x equals 0
Therefore, the equation of the line is y=3/5x-18

If the pool has 18 married and 22 not married, this means there are 40 people total
this means there’s a 18/40 probability that people who are married will be chosen
18/40 = 2/5
There is a 22/40 probability people who are un married will be chosen
22/40 = 11/20
