Answer:
75 + 64 = 139
Step-by-step explanation:
The measure of the exterior angle is 139
Answer:
2= 139
Step-by-step explanation:
A triangle is 180 degrees.
64+75= 139
180-139=41
A line is also 180 degrees
180- 41= 139

2^2x = 8^x-1
Answers
and
if a^x=a^y where a=a, then x=y so
make bases the same
2^(2x)=8^(x-1)
8=2^3
8^(x-1)=(2^3)^(x-1)=2^(3(x-1))
2^(2x)=2^(3(x-1))
threfor
2x=3(x-1)
2x=3x-3
0=x-3
3=x

October: 8 3/8 inches
September : 60% less rain fell than in October.
This means that only 40% rain fell in September based on the amount of rain that fell in October.
8 3/8 ⇒ (8*8)+3/8 = 67/8
40% is 4/10
67/8 * 4/10 = 268/80 = 3 28/80 or 3 7/20 or 3.35
28 ÷ 2 = 14
80 ÷ 2 = 40
14 ÷ 2 = 7
40 ÷ 2 = 20
In September 3 7/20 inches or 3.35 inches of rain fell.
60% of 8 3/8 in. = 60% * 8 3/8 = 60/100 * 67/8 = 201/40 = 5 1/40 in.
8 3/8 - 5 1/40 = 67/8 - 201/40 = 67/20 = 3 7/20 in.
The correct result would be 3 7/20 in.

Amount of dog treat that Dieon gives his dog each day = 1/8
Let us assume the number of days the dog treat will last = x
Then
(1/8) * x = (3/4)
x/8 = 3/4
x = (3 * 8)/4
= 3 * 2
= 6
So we can see from the above deduction that the dog treat will last for 6 days. I hope the procedure is clear enough for you to understand.

Answer:
Length of the arc = 5.25017 feet
Step-by-step explanation:
The line from the middle of the tree to the tip of the tangent lines is 33 ft and from the circumference of the tree its 27ft. One of the right angle triangles is picked and the angle is determined using SOHCAHTOA
Hence Tan X = 6/27
X = Tan-1 (6/27) = 12.52880770915o
Hence both sum of angles where tangent lines meet = 2 x 12.52880770915o = 25.05761541830o
Angle of the arc inside the circle = 50.115o
Length of the arc = 50.115/360 x (2x22/7 x 6) = 5.25017040025ft
B) 2 in.
C) 6 in.
D) 12 in.

1/4 x^2 = (x - 3)^2
x^2 = 4(x^2 - 6x + 9) = 4x^2 - 24x + 36
3x^2 - 24x + 36 = 0
3(x^2 - 8x + 12) = 0
x^2 - 8x + 12 = 0
x^2 - 2x - 6x + 12 = 0
x(x - 2) - 6(x - 2) = 0
(x - 6)(x - 2) = 0
x - 6 = 0 or x - 2 = 0
x = 6 or x = 2
but x cannot be 2 since the side length of the smaller square will be negative.
Therefore, the side length of the original square is 6 inches.
