Answer:
Min 80, Q1 82, Med. 85.5, Q3 93, Max 100.
90%.
Step-by-step explanation:
Percentage at least 82 = 100 *(100 - 82) / (100-80)
= 90%.
A) The new dimensions would be 32cm by 12cm.
B) This is an enlargement.
To find the new dimensions, multiply the original dimensions by the scale factor. 8*4=32 and 3*4=12.
This is an enlargement because the copy is larger than the original.
25 would be your final answer.
Answer:
Slope of the line y = x + 10 is 1. So, any straight line perpendicular to this must be having slope of (-1).
Let, the line be y = - x + b and it passes through (15, -5).
So, 15 = 5 + b
b = 10.
So, equation of that line: y = -x + 10
Or, x + y = 10.
Y-intercept of the line = 10 units.
The answer is 1 and 1/2 feet
