Each exterior angle = (360° / number of sides)
Each exterior angle = 3.6°
Answer:
They averaged 79 km per hour
Step-by-step explanation:
To find the average distance, take the kilometers and divide by the hours
1106 km/ 14 hours
79 km / hours
They averaged 79 km per hour
Answer:
108 square feet
Step-by-step explanation:
This question is essentially asking us for the area. (Don't be fooled into thinking this is a perimeter question. Imagine if you had a floor with just a ring of carpet on the edges!)
Let's separate this into areas we can understand. The square to the right, with dimensions 6 ft by 6ft, has an area of
A = s*s = 6*6 = 36 square feet
The rectangle that we have left has dimensions 12 ft by 6 ft, so it has an area of
A = l*w = 12*6 = 72 square feet
Add those together to get the total area.
A(rect) + A(square) = 72 + 36 = <u>108 square feet</u>
If AB = 16, then AC is (1/2)(AB) or 8.
(OC)^2 + 8^2 = 17^2
(OC)^2 = 17^2 - 8^2
(OC)^2 = 289 - 64
(OC)^2 = 289 - 64
(OC)^2 = 225
Taking the square root on both sides leads to OC = 15 cm.
