Answer: 0.18 seconds
step by step explanation: if it takes 0.09 seconds to knock down 4 dominoes, and you are trying to find out how long it will take to knock down 8 dominoes, you can see that 8/4=2, so you need to multiply 0.09 times 2 to get your answer, which is 0.18 seconds.
Total = 7 slices.
1student = 7/9 of a slice.

Answer:
26
Step-by-step explanation:
The sum of angles in a triangle is 180 degrees, use this and set up an equation;
x + ( 4x -5 ) + 55 = 180
Simplify
x + ( 4x - 5 ) + 55 = 180
5x + 50 = 180
Inverse operations;
5x + 50 = 180
-50 - 50
5x = 130
/5 /5
x = 26
26 feet divided by 15/2 inches
26 * 12 = 312
312 * 2/15
624/15
41 9/15
41 3/5
she can make 41 bracelets
ANSWER:
We know that the sum of angles of same sides in parallel lines are supplementary(180°).
So, ∠6 + 24° = 180°
- ∠6 = 180° - 24°
- ∠6 = 156°.
