171/3 is 57. the three consecutive numbers are 56, 57 and 58.
244/4 is 61. the even integers are 58, 60, 62 and 64
Answer and explanation:
We know the sum of interior angles in a triangle is 180°.
- 1 : 2 : 3 = 6 (1 + 2 + 3)
- x : y : z = 180 (x, y and z are the unknown angles)
To get from 6 to 180, we multiply by 30. This means we can find the angles by doing:
- 1 × 30 = 30°
- 2 × 30 = 60°
- 3 × 30 = 90°
The triangle must be right-angled because one of the angles is 90°. We know that the shape is a triangle because 30 + 60 + 90 = 180°.
The ratio is 30 : 60 : 90.
Hope this helps!
Answer:
126
Step-by-step explanation:
21 + 4 = 25 (blue plus white marbles)
150/25 = 6 (all the marbles divided by how many we know are white and blue)
21 x 6 = 126
Population=370000
Population growth=4.5%
Increase in Pop growth in a year=
( {100+4,5}/100 )×370000= 386,650 people
Therefore growth in 15years=
386650×15 =
5,413,100 people
