Answer: {4,5,6}
Step-by-step explanation: Sets could be explained as a representation of elements which could be numbers, alphabets or a collection of items which are wrapped inside a curly bracket {}. Generally in mathematical or statistical parlance, once elements are wrapped around curly braces, the collection of those emmts is called a set. And therefore, set arithmetic such as union, intersection, complement e.t.c can be performed on elements of the given set. Elements wrapped in curly braces signifies that the elements reperesents an entire entity.
In the question given above, {7,8,9} reperesents a set containing three elements : 7, 8,9.
6 / 4.5 = x / 6
x = 6* 6 / 4.5
x = 36/4.5
x = 8
SF = 4.5 / 6 = 0.75
answer
<span>A. Scale factor 0.75, x = 8</span>
Answer: 88 dollars
Step-by-step explanation: We will follow the pattern of 2s, so 2 4 6 8 10 12 14 16 is how much she saved over the course of all 8 weeks. 2 plus 4 equals 6. 6 plus 8 equals 14. 10 plus 12 is 22. 14 plus 16 is 30. 6 plus 14 is 30 and 22 plus 36 is 58. Last of all, 58 plus 30 is 88
16=1/4 d+2.5
Where d is diameter of larger gear
16-2.5=1/4d
D=74 cm
Answer:
m∠x = 119°
m∠y = 61°
m∠z = 119°
Step-by-step explanation:
Angle x:
- m∠x = 180° - 61° (sum of angles in a straight line)
- m∠x = 119°
Angle y:
- m∠y = 61° (Alternate interior angles)
Angle z:
- m∠z = 119° (Sum of angles in a line, corresponding angles)
