It depends on what did you mean by saying perfect square. If I've understood it correctly, I can help you with a part of your problem. The squares of mod <span>9</span><span> are </span><span><span>1</span><span>,4,7</span></span><span> which are came from </span><span><span>1,2,</span><span>4.</span></span><span> </span>Addition of the given numbers are 2,3,5,6, 8, which are exactly the part of your problem. This number, which is not shown as squares Mod 9, and thus doesn't appear as a sum of digits of a perfect square. I hope you will find it helpful.
20 m
Distance= Speed * Time
4 m/s * 5 s = 20 m
The answer is 2 because 14/7 equals 2.
The answer is C, 55x-26
-11x*-5 that is 55x
7*-5=-35
9-35=-26
so the ending expression is 55x-26
Answer:
97.6 in^3
Step-by-step explanation:
find the volume of the cylinder and then find the volume of the cone. the formula for the volume of the cylinder is pi*r^2*h. the formula for the volume of the cone is 1/3*pi*r^2*h. r=d/2=4/2=2, h(cylinder)=8, h(cone)=0.7. now just plug these values into the formulas.
cylinder: pi*2^2*8=100.531
cone: 1/3*pi*2^2*0.7=2.932
cylinder-cone= 100.531-2.932=97.599. round to the nearest tenth to get 97.6
