Answer:
They are both the same triangle, with different dilations
Step-by-step explanation:
(I hope this is right, I wasn't quite sure of the context)
Assuming that you typed it wrong, meaning you meant 1cm=1.5 sq meters,
then the answer is 45 meters
just multiply the length and the width to get the area
so, 5cm= 7.5 m
4cm= 6 m
7.5m multiplied by 6m is 45sq m
The correct answer for this is shown below in the picture
Answer:
x > -3/7
Step-by-step explanation:
Eliminate parentheses, collect terms, and subtract the constant on the left.
5(3 -x) -4(2 -3x) > 4
15 -5x -8 +12x > 4
7x +7 > 4
7x > -3
x > -3/7 . . . . . divide by the coefficient of x
A) 0.9803; 0.4803
B) 32
We calculate the z-score for this problem by using the formula:

Using our formula, we have:

Using a z-table (http://www.z-table.com) we see that the area to the left of, less than, this score is 0.9803.
To find the probability it is between the mean and this, we subtract the probability associated with the mean (0.5) from this:
0.9803 - 0.5 = 0.4803.
To find B, we first find the z-score for this. Using a z-table (http://www.z-table.com) we see that the closest z-score would be 2.33. We then set up our equation as

Multiplying both sides by 0.85 we have
2.33(0.85) = 0.35√n
1.9805 = 0.35√n
Divide both sides by 0.35:
1.9805/0.35 = √n
Square both sides:
(1.9805/0.35)² = n
32 ≈ n
