Answer:
1st statement is true
Step-by-step explanation:
The 1st statement is true since .25 is 25/100
The 2nd statement is false since 20 / 10 = 2 not .20 which is 2/10
The 3rd statement is false since 2/3 = .6666667 not .23
The 4th statement is false since .4 = 4/10 not 1/4 which is .25
Answer:
126 in²
Step-by-step explanation:
the surface on the top:
2*1/2*3*2 + 2[1/2]*3*2 = 21
the surface around:
3*8*4= 96
the surface of the bottom:
3*3= 9
total surface: 21+9+96 = 126
GOOD LUCK
Answer:
Apple A
Step-by-step explanation:
Apple A 6.90/6 = <u>1.15 lb</u>
Apple B 12oz/ (16oz or 1lb) =3/4 .90/(3/4) =<u>1.2lb</u>
Apple C 0.45/(1/4)= <u>1.8lb</u>
Answer:
Step-by-step explanation:
total metre = 10m
If one piece is 4m then 2m more then that = 4 + 2 = 6m
So total = 4 + 6 = 10m
Answer:
115°
Step-by-step explanation:
The sum of angle measures of a pentagon is 540°, so your unknown angle can be found from ...
... 103° + 100° +110° +112° +unknown = 540°
... unknown = 540° -425° = 115° . . . . . . . . subtract 425° from both sides

<em>Angles of a polygon</em>
The external angles lf a convex polygon always sum to 360°. The sum of internal and external angles is, of course, 180°. So, an n-sided polygon has internal angle measures that sum to ...
... n×180° - 360° = 180°×(n -2)
Thus, a pentagon has internal angles that sum to ...
... 180°×(5 - 2) = 540°
