Volume of the pipe = πr^2l
Wrong measure = π x (2)^2 x l = 4πl
Correct measure = π x (2 - 2(1/8))^2 x l = 49/16πl
error = 4πl - 49/16πl = 15/16πl
% error = ((15/16πl) / 49/16πl) x 100% = 30.6%
Answer:
x = 6
Step-by-step explanation:
Since the triangles are similar, we can use ratios to solve
20 24
--------- = ---------
5 x
Using cross products
20x = 24*5
20x = 120
Divide each side by 20
20x/20 = 120/2
x = 6
Answer:
slope of y = -7 is 0
Step-by-step explanation:
y = any number forms a graph of a horizontal line
x = any number forms a graph of a vertical line
For any horizontal line , the slope is always 0
for any vertical line , the graph is always undefined
So for y =-7 we will get a horizontal line at -7 on t
the slope of horizontal line y=-7 is 0
Answer:
Liam
Step-by-step explanation:
First we can change 12% to 0.12 then multiply 0.12 with 5 and get 0.6, so Stan has 0.6 of the flour, and we see that 0.11 is greater than 0.7 and 0.6
