Answer:
2 out of 10
Step-by-step explanation:
Simple math
solution:
a) The mean value of gap w̅ is given by,
w̅= d̅ - a̅ - b̅ - c̅
w̅=06.520-0.150-2.000-3.000
w̅=0.020 in
bilateral tolerances of the gap is given by,
tw = ∑t
tw = 0.001+0.003+0.004+0.010= 0.018 in
w = 0.020 ± 0.018 in
b) if wmin =0.010 in , then
w̅ = wmin + tw
w̅ = 0.010+ 0.018=0.028 in
mean size of d is
d̅ = a̅ + b̅+ c̅+ w̅
d̅ =1.500+2.000+3.000+0.028
= 6.528 in
Answer:
(-4,-2)
Step-by-step explanation:
first u should chose a variable to eliminate and i choose Y
y=5/2x+8-y=-1/4x-3
get a common denominator
5/2= 10/4
-1/4=-1/4
the equation i will change a little because we are subtracting
10/4x+8+1/4x+3
11/4x+11
solve for the remaining variable which is X
subtract 11 on both sides
0-11=11/4x+11-11
-11=11/4x
multiply both sides by 4/11
-11 times 4/11= 11/4x times 4/11
x=-4
then substitute the variable in one of the equations and i choose y=5/2x+8
5/2(-4)+8= y
-20/2+8= y
-10+8=y
y=-2
