You multiply the area by the scale factor twice. Here is an example: if we have a rectangle that has a length 3 and a height of 4 and the scale drawing with a scale factor of 2, how many times bigger is the scale drawings area? The original shape is 3 by 4 so we multiply those to find the area of 12 square units.
hope it helps!!!
Answer:
The distance between (9,1) to (1,8) is 3.26
Step-by-step explanation:
To solve this exercise we first have to calculate the distances between the factors of x and those of y
(x , y)
P1 = (9 , 1)
P2 = (1 , 8)
To calculate the distance we have to do P1 - P2
(9 , 1) - (1 , 8)
we subtract the corresponding from each other
9 - 1 = 8
1 - 8 = -7
(8 , -7)
Now that we have obtained these values, what we have to do is Pythagoras, since x represents a horizontal displacement, and y represents a vertical one, and the distance will be the hypotenuse that is formed from them.
h² = 8² + (-7)²
h² = 64 + 49
h² = 113
h = √113
h = 3.26
The distance between (9,1) to (1,8) is 3.26
The answer is -7 because if you subtract the first equation by the second equation then you’ll find the y-coordinate: 12. You use the second equation to find the x-coordinate.
23, 23, 23, 27, 32, 46, 51, 58, 61, 63, 73, 76, 76, 95, 95 what’s the lower quartile

Step-by-step explanation:
Answer:
∠1 = 103°
Step-by-step explanation:
supplementary angle to 136° = 180° - 136° = 44°
∠1 = 180° - 33° - 44° = 103°
