Answer:
Step-by-step explanation:
Okay so the 4(2t +2) and 4t + 8 + 4t go under 8t + 8, because when you distribute and add like terms, you get 8t+ 8 for both
(8*t)+(8*8) and 8t + 64 go under 8(t+8) because similar to the other, when you distribute and add like terms you get 8(t+8) for both
The last two options 8t+16 and (8+t) +(8+8) go under neither because when distributed and added, they don't match up to either or
Hope that helps!
Answer: C = 53.3 inches
A = 226.1 inches²
Step-by-step explanation:
The inscribed square has equal sides. To determine the hypotenuse of the square which is also the diameter of the circle, we would apply the Pythagoras theorem which is expressed as
Hypotenuse² = opposite side² + adjacent side²
Hypotenuse² = 12² + 12² = 144 + 144 = 288
Hypotenuse = √288 = 16.97 inches
Radius = diameter/2 = 16.97/2 = 8.485 inches
The formula for determining the circumference of a circle is expressed as
Circumference = 2πr
Circumference = 2 × 3.14 × 8.485 = 53.3 inches
Area = πr²
Area = 3.14 × 8.485² = 226.1 inches²
The distance for robot walks speed is D 20 feet per minute
Answer:
Step-by-step explanation:
In the attached diagram
CA=CO+OA
CO=DB
Therefore:
5=2+OA
OA=3 Units
The angle between a tangent line and a radius is 90 degrees. therefore triangle OAB is a right triangle with:
OB=12 units
OA=3 units
Using Pythagoras theorem
1 yard is equal to 3 feet.
So you want to take 63 and divide it by 3.
63/3=21.
There are 21 yards in 63 feet.
Hope this helps!
