Answer:
28meters and 112meters
Step-by-step explanation:
one piece is x
the other is 4x
therefore; 4x+x=140
5x= 140
divide both sides by 5
x=28
4x=4(28)
=112
Answer:
All sides of a triangle should equal 180 degrees, so just add up the given sides and subtract them from 180
Step-by-step explanation:
Answer: 90 people
Step-by-step explanation:
3 ladles per person = 150 people x 3
= 450 ladles full
450 ladles full = 5 ladles per one person = 450/5 = 90 people
Answer:
31.7 cm²
Step-by-step explanation:
The area (A) of the triangle is calculated as
A = 
absinC
where a, b are the 2 sides given and C the angle between them
∠ C = 180° - (72 + 59)° = 180° - 131° = 49° , thus
A = 0.5 × 12 × 7 × sin49° ≈ 31.7 cm² ( to 1 dec. place )
Answer:
B) 9
Step-by-step explanation:
110 + 75 + 11x - 9 + 8x + 13 = 360
19x + 189 = 360
19x (+ 189 - 189) = 360 - 189
19x = 171
19x/19 = 171/19
x = 9
