Answer:
<em>900° </em>
Step-by-step explanation:
The interior angles sum = 180° ( n - 2 )
~~~~~~~~
n = 7
180° ( 7 - 2 ) = <em>900°</em>
Answer:
3x + y - 2 = 0
Step-by-step explanation:
The equation of a line in general form is
Ax + By + C = 0 ( A is a positive integer and B, C are integers )
Given
- 3x - y + 2 = 0 ← multiply through by - 1
3x + y - 2 = 0 ← in general form
Answer:
52°
Step-by-step explanation:
The angle 38° and m∠1 equal 90°, so 90-38=52.
Step-by-step explanation:
since the ratio of children to adult is 2:7,
2+7 = 9
number of children would be
(2 × 2700)/9 = 600 children in the crowd
number of adults would be
(7 × 2700)/9 = 2100 adults in the crowd
So, if a ticket costs £8 per adults, total cash made from adult
= 8 × 2100 = £16800
if a ticket costs £(8 - 3) per children, total cash made from children
= 5 × 600 = £3000
total money made = £(16800 + 3000)
= £19800
