Answer by JKismyhusbandbae: It is known as Interquartile range you get this by dividing a data set into quartiles. Quartiles divide a rank-ordered data set 1st quartile, 2nd quartile, 3rd quartile.
Answer:
40 mL of 10% acid
80 mL of 25% acid
Step-by-step explanation:
x = volume of 10% acid solution
y = volume of 25% acid solution
Total volume is:
x + y = 120
Total amount of acid is:
0.10 x + 0.25 y = 0.20 (120)
Solve by substitution.
0.10 x + 0.25 (120 − x) = 0.20 (120)
0.10 x + 30 − 0.25 x = 24
0.15 x = 6
x = 40
y = 80
Answer:
The dilation is twice the original form
Step-by-step explanation:
Given
Original Triangle = ABC
Dilated Image = A'B'C'
Required
Relationship between both
From the attached diagram;
This implies that
The relationship between a dilated image and its original form is;
Using AC and A'C';
Such that A'C" is the Dilation image of AC
Replace AC an A'C' with their lengths
Divide both sides by 5
Hence, the dilation is twice the original form

Answer:
330
Step-by-step explanation:
When we are at 30 degrees on the unit circle, we are at the point (/2, 1/2) so if we go to -30 degrees (330 degrees), we will be at point (-/2, -1/2).
