Let the original volume be pi *r^2* h where r = radius and h = height.
The new volume will be pi *(2/5 r)^2 * 4h = pi*4/25 r^2 4h
pi*4/25r^2 * 4h / pi r^2 h = 4/25 * 4 = 16/25
The volume has been reduced by factor of 16/25.
Answer:
ACBD; 7
Step-by-step Explanation:
The Route Algorigtm finds the short route that is efficient, in order to find the solution following pathways.
From the pictures from the complete question,
STEP #1, there exist, three routes, which are:
AB
AC,
and AD.
*AB is not viable because of the negative distance, so it can be removed .
* the AC distance is 3,and AD distance is 8. Therefore, AC can be selected and circled.is because of AC efficiency is high compare to AD.
*from selected AC, the possible routes are ACB; 3 and ACE; 6. which are route shown in #2
* ACB is circled, because it's more shorter than ACE
*The possible routes are ACBE; 8 and ACBD; 7. which are route shown in #3 . Therefore, route ACBD is circled because it's more shorter.
From the analysis of the algorithm, the route ACBD route is the shortest and the most efficient
Answer:
Incorrect.
Step-by-step explanation:
Let, the first number is x, and the second number is y. Given, the second number is 125% of the first number. So, the equation will be
y = 1.25 x
Or, y= 5/4x
Now, multiplying it with 4/5, we get, x= 4/5y
Or, x= 0.80 y
But, Brad is saying the first number must be 75% of the second number. But here we see that the first number is 80% of the second number. That's why Brad is incorrect.
Answer:
Sides are x and x + 3.5 cm
Perimeter = 2(x + (x + 3.5))cm
4x +7 = 67
x = 15cm Answer
