Answer:
Ans; Base=19.799cm
each of the other two sides=14cm
Step-by-step explanation:
two isosceles triangles are going to give you a square. So that means the area of the square will be 2(98cm^2) cos u added two of the triangles.There fore to get each side of the square, find the square root of the area of the square.you will get 14cm.that is equal to the length of the other two sides of the triangle. the base of the triangle is equal to the diagonals of the square(d=s√2).Use that to find the base of the triangle. Hope this helps.I am not good at explaining though

Answer:
The new volume is 1/343 of the old volume or the ratio of the new volume to the old volume is 1 to 343
Step-by-step explanation:
In this question, we are asked to state the effect of multiplying the radius of a sphere by 1/7 on the volume.
Mathematically, the volume of a sphere V can be calculated using the formula
V = 4/3 * π * r^3
Now multiplying the radius by 1/7, the new radius will be r/7
Thus the new volume here will be
V2 = 4/3 * π * (r/7)^3
V2 = 4/3 * π * (r^3)/343
Thus we can conclude that the value of the volume will be decreased by a factor of 343
Meaning the ratio of the old volume to the new volume will be 1 to 343
10a - 5b = 25
10a - 10a - 5b = 25 - 10a
-5b = -10a + 25
-5 -5
b = 2a - 5
