Answer:
the answer to this question is equal to 162
(6x + 30)+(2x+6)= 180
8x +36= 180
8x= 144
X= 18
So 2x+6 = 42
And 6x+30 = 138
Hhey it should be

just because they all have a chance :) hope it helps
Answer:
13 students were fed
Step-by-step explanation:
now first in order to count we will have to turn 3 1/4 into a whole number which means we will have to multiply the denomintor by 3 and add it to the numerator which is 1
4 x 3= 12 ..... 12 + 1 = 13
13/4 and the denominator always stays the same
and now to count we will have to divide 13/4 divided by 1/4
now instead of dividing you can just multiply them by switching the denominator and numerator 1/4 to 4/1
13/4 x 4/1
52/4
13
Answer:
25.9%
Step-by-step explanation:
Note: you did not provide any attached image detailing the dimension of the cylinder however, let us arrange some dimension for explanation purpose
let the dimension of the cylinder be
radius= 3in
height= 5 in
Step two
The expression for the total surface area of a cylinder is
T. S. A. =2πrh+2πr2
substitute
T. S. A. =2*3.142*3*5+2*3.142*3^2
T. S. A. =94.26+56.556
T. S. A. =150.816 in^2
Now let us find the error
%error= actual -expected/expected*100
%error= 190 -150.816/150.816*100
%error= 39.184/150.816*100
%error= 0.259*100
%error= 25.9%
Now, you can use the dimension you have for the cylinder to calculate the total surface area, from there, you can solve for the error by following the steps above
