Answer:
Step-by-step explanation:
y = mx + b
y = -x/3 + b
1 = -2/3 + b
b = 5/3
y = -x/3 + 5/3

Answer:
r = 35.18 mm
Step-by-step explanation:
We have,
The diameter of a reamed hole is 70.36 mm.
It is required to find the radius required to draw the hole.
The relation between diameter and radius is given by :
D = 2r
r is radius setting
So, the radius setting used to draw the hole is 35.18 mm.
1. To solve this problem, you must apply the formula for calculate the area of the trapezoid, which is:
A=(B+b)h/2
A is the area of the trapezoid (A=69.6 in²).
(B+b) is the sum of the bases of the trapezoid.
h is the height of the trapezoid (h=8.7 in).
2. When you clear the sum of the bases (B+b), you have:
A=(B+b)h/2
2A=<span>(B+b)h
</span><span> (B+b)=2A/h
</span> (B+b)=2(69.6 in²)/(8.7 in)
(B+b)=16 in
3. The problem says that <span>the sum of its legs is equal to the sum of its bases, therefore, the perimeter is:
</span>
Sum of the legs=Sum of the bases (B+b)=16 in
Perimeter=16 in+16 in
Perimeter=32 in
