Answer:
The larger angle is 143
Step-by-step explanation:
x + y = 180 (This is the meaning of supplementary. Two angles make up 180 degrees)
4x - 5 = y
x + (4x - 5) = 180 Remove the brackets.
x + 4x - 5 = 180
5x - 5 = 180 Add 5 to both sides
5x - 5 +5 = 180 + 5 Combine
5x = 185 Divide by 5
5x/5=185/5
x = 37
y = 4*37 - 5
y = 148 - 5
y = 143
Answer:
b=42
c=180
Step-by-step explanation:
64 less than y = y-64
no less = greater or equal than
negative 128 = -128
y-64 ≥ -128
Add 64 to both sides of the inequality:
y-64+64 ≥ -128+64
y ≥ -64

Answer:14.4In^3
Step-by-step explanation:
Diameter=3.8In
radius(r)=3.8 ➗ 2=1.9In
volume of hemisphere=2/3 x π x r^3
Volume=2/3 x 3.14 x(1.9)^3
Volume=2/3x3.14x1.9x1.9x1.9
Volume=(2x3.14x1.9x1.9x1.9) ➗ 3
Volume=43.07452 ➗ 3
Volume=14.4In^3
