Answer:
n> -30
Step-by-step explanation:
move the -2n to the left
the 3 to the right
then move the negative
Answer:
0.6625 in²
Step-by-step explanation:
The surface area of this figure will be the area of the base added to area of the triangles
Area of the 4 triangles
Area of a triangle is given by ;
where b is the base length and h is the height of the triangle
<u>Area of 1 triangle</u>
Given base length as 0.25 inches and height is 1.2 inches.
Area of all 4 triangles
- multiply the area of one triangle by 4
- 0.15*4=0.6 in²
<u>Area of the base</u>
The base is a square of length 0.25 inches
Area of a square=length×length
<u>Total surface area</u>
Total surface area= Area of the triangles + Area of the base
Answer:
from now on don't ask same qn two times or more it would be waste of your points
got it??
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
The answer is an equilateral triangle
