Answer 16
Step-by-step explanation:
Answer:
Width = 4.85 feet
Length = 7.85 feet
Step-by-step explanation:
Given:
Perimeter of a rectangle = 25 2/5 ft = 25.4 feet
Length = 3 + Width
Computation:
Assume;
Width = a
So,
Length = 3 + a
Perimeter of a rectangle = 2(l + b)
25.4 = 2[(3 + a) + a]
25.4 = 2[3 + 2a]
25.4 = 6 + 4a
4a = 19.4
a = 4.85
Width = 4.85 feet
Length = 3 + 4.85
Length = 7.85 feet

Answer:
y = -2x + 10
Step-by-step explanation:
The equation is y = mx + b
1. Find the slope first.
--> (y2 - y1) / (x2 - x1) = slope
--> (-12 - -6) / (11 - 8) = (-6) / (3) = -2
2. Then, find the y-intercept (b) by plugging one of the points
--> y = -2x + b
--> -6 = -2(8) + b
--> -6 = -16 + b
--> b = 10
3. Combine
--> y = -2x + 10

Answer:
m∠1 +m∠8 = 90°
Step-by-step explanation:
There is no necessary sum relation between angles 3 and 5 or angles 7 and 10. The only thing you can say about those angle pairs is ...
∠3 + 90° = ∠5
∠10 +90° = ∠7
Angles 8 and 9 are congruent, so don't have any necessary sum.
Angle 1 is congruent with angle 3, which is complementary to angle 8, so we must have ...
m∠1 +m∠8 = 90°
