Here are three lamps.
lamp C
lamp B
lamp A
Lamp A flashes every 20 seconds.
Lamp B flashes every 45 seconds.
Lamp C flashes every 120 seconds.
The three lamps start flashing at the same time.
How many times in one hour will the three lamps flash at the same time?​

Answers

Answer with step-by-step explanation:

First of all, we need to calculate how many times the 3 lamps flash in a minute. We can do this by finding their LCM (least common multiple), which is 360. 360 is equivalent to 6 minutes, so that is going to be our test time. Lamp a flashes every 20 seconds, so 360/20 = 18 flashes. Then, 360/45 = 8 flashes. Finally, 360/120 = 3 flashes. 18 + 8 + 3 = 29 flashes per 6 minutes. If so, we multiply 29 by 10, because 60 minutes per hour ÷ 6 minutes = 10. So 29 × 10 = 290 flashes per hour

2x-1+9x+3=57 solve for X

Answers

Answer:

x = 5

Step-by-step explanation:

2x-1+9x+3=57

2x+9x=57+1-3

11x=55

x= 55/11

x= 5

Answer:

x = 5

Step-by-step explanation:

Simplifying 2x + -1 + 9x + 3 = 57

Reorder the terms: -1 + 3 + 2x + 9x = 57

Combine like terms: -1 + 3 = 2 2 + 2x + 9x = 57

Combine like terms: 2x + 9x = 11x 2 + 11x = 57

Solving 2 + 11x = 57

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2' to each side of the equation. 2 + -2 + 11x = 57 + -2

Combine like terms: 2 + -2 = 0 0 + 11x = 57 + -2 11x = 57 + -2

Combine like terms: 57 + -2 = 55 11x = 55

Divide each side by '11'. x = 5

Simplifying x = 5

Answer:

C) 6^6

Step-by-step explanation:

When we divide same base numbers with different exponents, the answer will be the base raised to the power of the difference of those exponents:

The rule is: x^a/x^b=x^(a-b)

In this case: 6^9/6^3=6^(9-3)=6^6=46656

16r6sc/8r2s6 Which expression is equivalent to the given expression? Assume the denominator does not equal zero. A. B. C. D.

Answers

Answer:

B.  

Step-by-step explanation:

The required expression is equivalent to the given expression is C.

An equivalent expression for 16r6sc/8r2s6 is to determine.

What is the Ratio?

The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.
Numerator = it is the term positioned above in the ratio
Denominator = it is the term positioned below in the ratio

Here,  
= 16r6sc/8r2s6
Factored 16 into 8 * 2
= 8*2r6sc/8r2s6
Rearrange the numerator in order to simplify relative to denominator.
=8r2s6c/8r2s6
8r2s6 are common in the denominator and the numerator of the ratio denominator does not equal zero so it implies
=c/1

Thus the required expression is equivalent to the given expression is C.

Combine like terms

-2 -4a = 8+a

Add 4a to each side

-2-4a+4a=8+a+4a

From the given figure, lines GN and FH are intersecting by the line segments KL and JM.

What are angles of parallel lines?

Angles in parallel lines are angles that are created when two parallel lines are intersected by another line called a transversal.

From the given figure, we can see that

∠6 = ∠10 (Corresponding angles are congruent)

∠10 = ∠13 (Vertical angles are congruent)

Now, ∠6 = ∠10 = ∠13

The corresponding angles postulate and the vertical angles theorem are proving ∠6 = ∠13. Therefore, options B and D are correct answer.
