Answer:
A) x < -3
Step-by-step explanation:
Answer:
Inputs:
Radius (r):
0.65
or
Diameter (d):
1.3
or
Area (A):
1.327
Unit of Lenght:
centimeter
Calculate Circumference
Result:
The circumference of a circle with diameter 1.3 is 4.084(*)
Formulas:
r = 0.65
d = 1.3
C = 4.08
C = 2·π·r C = π·d C = √4·π·A π = 3.1415
A = area of the circle
C = circumference or perimeter
r = radius, d = diameter
Step-by-step Solution:
Circumference of a cicle in terms of radius:
Circumference = 2·π·r = 2·3.14·0.65 = 4.09(*)
In terms of diameter:
Circumference = π·d = 3.14·1.3 = 4.08(*)
In terms of area:
Circumference C = √4·π·A = √4·π·1.33 = 4.09(*)
(*) 4.084 cm exactly or limited to de precision of this calculator (13 decimal places).
Note: for simplicity, the operations above were rounded to 2 decimal places and π was rounded to 3.14.
A circumference of 4.084 centimeters is equal to:
4.084E-5 kilometers (km)
0.04084 meters (m)
40.84 millimeters (mm)
2.53768E-5 miles (mi)
0.0446632 yards (yd)
0.13399 feet (ft)
1.60787 inches (in)
Answer:
3m² + 2mn + 7n²
Step-by-step explanation:
Subtract m² + 3mn - n² from 4m² + 5mn + 6n², that is
4m² + 5mn + 6n² - (m² + 3mn - n²)
= 4m² + 5mn + 6n² - m² - 3mn + n² ← collect like terms
= 3m² + 2mn + 7n²
Answer:
Step-by-step explanation:
1) ∠1 + ∠2 = 180 {linear pair}
105 +∠2 = 180
∠2 = 180 - 105
∠2 = 75°
Reason: Linear pair
2) ∠3 = ∠1 {Vertically opposite angles are congruent}
∠3 = 105
Reason: Vertically opposite angles are congruent
Approximately 2%. The reason is if you choose 20% and only have four with beef as the most popular, and approximately the number of restaurants is 15.
