1. $30.10 after you add, and then multiply to
ReplyDeletetimes.
Outstanding! P= total of the sides of a triangle
ReplyDeleteIf this would have been an equilateral triangle you could have multiplied one side by 3 and solved for the perimeter.
2. 11 with some slices left over.
ReplyDeleteFirst you had to determine how many total slices of pizza the band members would eat. 72 Then you divided 7 slices per pizza into 72 and you come up with 10.285 and then rounding it off and since your problem does not allow you to buy pizza slices but rather whole pizza you would need to buy 11 pizzas. YOu would have a few slices left over.
ReplyDelete3. .33m is the corect answer.
ReplyDeleteGood, Again you have to remember what a pentagon is. It is a five sided figure. Actually, the US Military Headquarters in Washington, D. C. is in the shape of a pentagon and that is why they call it the Pentagon. This building was hit on 9/11/2001.
ReplyDelete4. 58 Members play kazoos. 13 play tamborines and cowbells.
ReplyDeleteSolve for how many play something other than kuzzos 2/6 play tamborines and cowbells. 4/6 play kuzzos. So 78 X 4/6 = 52 13 play tamborines or 1/6 and 13 play cowbells or 1/6
ReplyDelete4. Sorry I mean 52 members!
ReplyDelete5. 118 inches in the perimeter.
ReplyDeleteto solve for a rectangle's perimeter. P=L X 2 + W X 2 and really is the total of all sides around the outside of the rectangle.
ReplyDelete118 inches in this case.
6. 321/1000, because the 0 in front of the #
ReplyDeletehas no purpose
batting average in a fraction would be simply reading where the decimal point is and since this one has three numbers to the right; it would be 1000ths.
ReplyDelete7. 88, after you multiply 8x11.
ReplyDeleteExcellent! You know that an Octagon is 8 sided so you multiply the one side by 8 and you solve for the perimeter. Good Job Have a GREAT DAY!
ReplyDelete8. 17.92
ReplyDeleteRemember that C=pi X d or C= 2r x pi
ReplyDeleteSo, 10 cm is diameter therefore pi=3.14 x 10 cm= 31.4 cm for the circumference.
In our next example where d = 5 then the circumference is 15.7 if you use the formula C=pi x d Also, remember that r or the radius is 1/2 the diameter in any circle.
9. 31.4 , after you drop the zero.
ReplyDelete15.7 is correct in the problem I suggested over the phone. It is important that you memorize these formulas for finding circumference in circles and perimeters in polygons.
ReplyDelete10. 6 choices in all.
ReplyDeleteBrian built a scale model of the log cabin Abraham Lincoln lived in when he was a child. The model is a rectangle with a length of 35 inches and a width of 24 inches. What is the area in inches of this structure?
ReplyDelete840 sq. inches
ReplyDeleteA=LXW and we now identify it as Square inches in the answer. Also, remember that if we had a height of 10 inches in this structure we could solve for volume
ReplyDeleteV=LXWXH and this would be identified as cubic inches because we would have a cube
Mackenzie bought a mansion with a very small bathroom, it had a width of 10 inches a length
ReplyDeleteof 10, and a hidth of 14 inches. What is the area?
100 sq inches A=lxw and the volume would be 1400 cubic inches because V=lxwxh
