Answer:
49ft
Step-by-step explanation:
4×10=40
6×3/2=9
40+9=49
Answer:
60°,60° and 60°.
Step-by-step explanation:
The sum of the interior angle of a triangle
=180°
So, let us test measured sets to get which of them could be the interior angles of a triangle.
The sum of the first measured set
= 90° + 42° + 58°
=190°
Also, the sum of the second measured set
= 60°+ 60° + 60°
=180°
The sum of the third measured set,
= 100°+ 48° + 43°
=191°
Finally, the sum of the fourth measured set
= 31° + 75°+ 70°
=176°
We can clearly conclude that, the measured set 60°,60°and 60° could only be the the set of interior angles of a triangle. Since it is the only set that add up to 180°
Answer:
≈ 70.4 cm
Step-by-step explanation:
The circumference (C) of a circle is calculated as
C = 2πr ( r is the radius ) , thus
C = 2 × 3.142 × 11.2 ≈ 70.4 ( to 1 dec. place )
20 because it is counting by fives (5,10,15,20) and 5x4=20
Answer:
slope = 0
Step-by-step explanation:
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (4, - 1 ) and (x₂, y₂ ) = (3, - 1 )
m = 
= 
= 
= 0
