Answer:
219 Seconds ; He was 1 second faster
Step-by-step explanation:
Two halfs equal one whole, meaning both of the times added will equal the full time he took:
95+124=219
219 Seconds
He was 1 second faster because:
219-218=1
-2.2*2.2*-1.6=7.744
Hope this helps!

Answer:
Use the given length of a different side of the triangle to determine the value of x if x is the length of one side. Every side of an equilateral triangle is the same. Multiply the length of one side of the triangle by three to find the value of x, if x is the triangle's perimeter.
A regular triangular pyramid is a solid figure with r surfaces
- 3 lateral surfaces and one base surface
- the four surfaces are congruent triangles, which is to say that all triangular surfaces have the same base and the same slant heght
- the area of each surface is [1/2] base * slant height.
Then, a change that double the area is any that keep one of the dimensiones and double the other.
So the answer is: double each side, b, of the base triangle while keeping the slant height, l, tha same.
You can also double the slant height, l, while keeping the base triangle, but then the height,h, of the pyramid will increase, by a factor which is not 2.
