Answer:
The question has some details missing. The remaining part of the question says ;
Determine
a) The stagnation temperature Tox in K
b) The stagnation pressure Pox in bar
c) The pressure Px in bar
d) The pressure py in bar
e) The stagnation pressure Poy in bar
f) The stagnation temperature Toy in K
g) If the throat area is 7.6 x 10^-4m2, and the exit plane pressure is 2.4bar, determine the mass flow rate in kg/s and the exit area in m2
Step-by-step explanation:
The detailed step by step calculation and appropriate substitution is carefully shown in the attached files
The volume is around 50.27
the surface area is: 75.4
the perimeter 25.13
Her average in first three test = 89
This means, her total scores in first three test were = 3 x 89 = 267
Her average in four tests = 91
This means, her total scores in four tests are = 364
267 give the sum of first three test scores. and 364 give the sum of scores with fourth test adding in three tests.
So, subtracting 267 from 364 will give us the scores of Fourth test.
Scores of Fourth test = 364 - 267 = 97
Thus, Samantha's Claim is correct
Answer:
B
Step-by-step explanation:
You are moving from Q to S. The scale factor is larger than 1. That makes 2/7 the wrong scale factor, which means that A and D are both incorrect.
But what is true between B and C.
So set up the proportion
4:14 = -2:S
4/14 = -2/S Cross Multiply
4s = 14 * - 2
4s = - 28
4s/4 = - 28/4
s = - 7
So the correct answer is (-7,0) with a scale factor of 7/2
Correct answer B
