Answer:
Hiiiiii
Step-by-step explanation:
4 x 5 = 20
20 x 5 = 100
I assume the next number in this sequence will be 500, as 100 x 5 = 500.
Answer:
36 minutes
Step-by-step explanation:
We can write a ratio
2 laps 9 laps
------------- = --------------
8 minutes x minutes
Using cross products
2x = 8*9
2x = 72
Divide by 2
2x/2 = 72/2
x = 36 minutes

Answer:

Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
sum the 3 angles and equate to 180
5x + 7 + 4x + 2 + 90 = 180 , that is
9x + 99 = 180 ( subtract 99 from both sides )
9x = 81 ( divide both sides by 9 )
x = 9
Then
∠ ACB = 4x + 2 = 4(9) + 2 = 36 + 2 = 38°
∠ BAC = 5x + 7 = 5(9) + 7 = 45 + 7 = 52°
-----------------------------------------------------------------------
Since the triangles are congruent then corresponding angles are congruent , so
∠ B = ∠ E
6x + 10 = 70 ( subtract 10 from both sides )
6x = 60 ( divide both sides by 6 )
x = 10
