Answer: 
Step-by-step explanation:
1. You must apply the following formula for calculate the total surface area the regular pyramid:
Where p is the perimeter of the base, l is the slant height and B is the area of the base.
2. The perimeter is, where s is the side length:
3. The faces are isosceles traingles. So, to find the slant height you can divide one base into two equal right triangles and calculate the slant height with Pythagorean Theorem:
4. The base is equal to any face, then both have equal areas. As previously you divide one base into two equal righ triangle to find the slant height, you can calcualte the area of one right triangle and multply it by 2 to calculate B:
Finally substitute values:
Answer:
Midpoint....; (0,-6)
Step-by-step explanation:
Midpoint of the segment
= [(sum of x-coordinates) ÷ 2] , [(sum of y-coordinates) ÷ 2]
Midpoint = [( 3 + (-3))÷ 2 , (-5 + (-7))÷ 2]
Midpoint = ( 0/2 , -12/2 )
Midpoint = (0,-6)
Answer:
All four Sets didn't work
Step-by-step explanation:
You should be doing hypothnose aka: a² + b² = c²
If they both equal that means they are a right triangle.
Set 1:
24² + 26² = 110²
576 + 676 = 10²
1252 = 12100
No
Set 2:
2² + 4² = 6²
4 + 16 = 6²
20 = 36
No
Set 3:
13² + 14² = 15²
169 + 196 = 15²
365 = 225
No
Set 4:
10² + 20² = 30²
100 + 400 = 30²
500 = 900
No
Answer:
probably cuz its in parentheses but there's no picture
Step-by-step explanation:
Using a calculator, 1200/180 = 6.67 approximately
If you use long division, then you'll get what you see in the diagram below
The 6's go on forever after the decimal point, but if you round to two decimal places, then you'll get that approximate value of 6.67
---------------
If you want a remainder, then 1200/180 = 6 remainder 120
You can think of it like you having 1200 cookies and 180 friends. Each friend will get 6 whole cookies and there will be 120 left over as the remainder.
