Answer:
-18.
Step-by-step explanation:
They're both negative numbers being added to each other, so you'd add 6 and 12 (which is 18) and then put a negative sign before the 18. Therefore, your answer is -18.
I hope this helps, have a nice day.
Answer:The perimeter =12w
Step-by-step explanation:
Let the width represent W and Length represent L
Length= 5 x width
L=5W
W=W
Since perimeter =2(L+w)
Substitute for L=5w
=2(5w+w)
=2(6w)
=12w
<u>Answer:</u>
The correct answer option is 153
.
<u>Step-by-step explanation:</u>
We are given a cylinder with a radius of 4.5 mm and a height of 17 mm and we are to find the lateral area of this cylinder.
We know that the formula of the lateral area of a cylinder is given by:
Lateral area of cylinder = 
Substituting the given values in the formula to get:
Lateral Area = 
= 153
"Dimensional analysis" is the primary way to make conversions between any units. Some have trouble because they fail to make it an important point to label units, but labeling units correctly makes tracking and making any conversion very simple...The process and thinking is that you want to cancel out units that you don't need in the solutions...
(198ft/s)(12in/ft)(2.54cm/in)(m/100cm)=60.3504m/s (and that is exact)
d=5s(60.3504m/s)=301.752m
ugh...assume that a meter equals 3.3 feet and do not round your answers???
really? These people are idiots when there is an exact conversion. What is the point of not rounding when you are using a horrible approximation? :D
(198ft/s)(m/3.3ft)=60m/s
d=5s(60m/s)=300m
