Answer:
1. 5\7.5 =2\3
2. 7\100=3.5\50
Step-by-step explanation:
The best way to solve this is to write it out part by part.
The first part is "the sum of 8 and 3," which is (8+3)
The second part is "...times a number," so we have n(8+3)
Lastly, "...is 23," means n(8+3) = 23, so here's the equation. In order to solve for n, divide both sides by (8+3) so 23/(8+3) which is 23/11. So the "number" is 23/11.
Sector area = central angle / 360 * PI * radius^2
98 PI = (1 / 2) * PI * radius^2
radius^2 = 196
radius = 14
Is there a picture of the question? 2 13 pencils and 3 34 minutes doesn't make sense
Answer:
48
Step-by-step explanation:
(264 in)/(5.5 in/piece) = (264/5.5) pieces = 48 pieces
_____
Division is the usual shortcut for repeated subtraction. You could subtract 5.5 from 264 until you get to zero. You would have to do 48 subtractions. It is easier to divide 264 by 5.5 to see how many times it goes.
