Answer:
19.105 in if c is the hypotenuse
5.196 in if c is a leg
Step-by-step explanation:
The Pythagorean theorem is used for this.
If c is the hypotenuse, ...
... c² = 13² + 14² = 365
... c = √365 ≈ 19.105 . . . . in
_____
If c is a leg, ...
... 14² = 13² + c²
... c² = 196 -169 = 27
... c = √27 ≈ 5.196 . . . . in

Step-by-step explanation:
Vika: 1= 15 minutes
Sandy: 1= 10 minutes
Hyun: 1= 7 minutes
43.586- anything 5 and more rounds up, so the 6 rounds the 8 up to 9, the 9 rounds the 5 up to a 6, so your answer wound be 43.6 because 43.5(tenths)8(hundredths)6(thousandths), i hope this helps

Answer:
A. 220
Step-by-step explanation:
To find the total surface area of a square pyramid, you have to find the area of the base and all of the sides and add them together.
To find the area of the base:
Since the base is a square, all we have to do is multiply the length by itself.
10 * 10 = 100
The base is 100 square centimeters
To find the area of the sides:
Since the sides are triangles, we have to multiply the length times the height and divide it by 2.
10 * 6 = 60
60/2 = 30
The area of one side is 30 square centimeters
To find the total surface area:
Add the area of all 4 sides and the area of the base together to find the total surface area.
4(30) + 100 = surface area
120 + 100
220 = surface area
The surface area is A. 220 square centimeters.
