Simon can see two lights, light A and light B.

Mathematics
1 answer:
xz_007 [3.2K]3 years ago
3 0

Answer:

2 Times

Step-by-step explanation:

Simon can see two lights A and B

  • Light A flashes every 15 seconds.
  • Light B flashes every 18 seconds.

First, we determine the next time both lights will flash together.

This is done by finding the Least Common Multiple of 15 and 18.

15=3X5

18=2X3^2

LCM of 15 and 18=2X3^2X5=90

This means that lights A and B will first flash together after 90 seconds.

Now, 240/90=2.\overline{6} seconds

Therefore, the number of times more both light will flash together in the next 4 Minutes= 2 Times

Solve for x - PLEASE NEED HELP, this is my 3rd time posting it.
mafiozo [28]

Answer:

x=58

Step-by-step explanation:

First, remember that the maximum degree of an angle totals 360°.

Since we already have 294°, this means that what is left must total 360\textdegree - 294\textdegree= 66\textdegree.

Therefore, this means that our two smaller angles must equal 66°. So:

(36)+(x-28)=66

Solve for x. Add on the left:

x+8=66

Subtract 8 from both sides. Therefore, the value of x is:

x=58

Eve is making a bird house. To make the walls she takes a piece of wood and cuts it into 4 pieces in the ratio 5:6:6:7. The long
allsm [11]

Answer:

The original piece of wood is 108 cm

Step-by-step explanation:

From the given ratio, the shortest is of the ratio 5 and the longest is of the ratio 7

Let the original piece of wood be x

so the sum of the ratios will be;

5 + 6 + 6 + 7 = 24

the shortest length would be 5/24 * x

= 5x/24

the longest will be 7/24 * x = 7x/24

From the question;

7x/24 -5x/24 = 9

(7x-5x) = 24(9)

2x = 24(9)

x = (24 * 9)/2

x = 108 cm

Solve 5c − c + 10 = 34. <br> −6 <br> 6 <br> 11 <br> −11
natima [27]

Subtract 10 and collect terms to get the variable term by itself on the left.

... 4c = 24

Divide by the coefficient of the variable, 4.

... c = 6

The appropriate choice is the second one:

... 6

_____

You don't actually have to sove the equation to find the right answer. You just need to see which answer works.

-6: 5(-6) -(-6) +10 = -14 ≠ 34

6: 5(6) -(6) +10 = 34 . . . . . . . this answer works (you can stop here)

11: 5(11) -(11) +10 = 54 ≠ 34

-11: 5(-11) -(-11) +10 = -34 ≠ 34
