Sumaya is using two different strings of Christmas lights to decorate her house.one string flashes every 10 seconds.the other one string flashes every 15 seconds.when Sumaya turns on the lights they flashes at the same time.work out how long it will be before they flash again at the same time.use the LCM to help you work out your answer

Answers

Answer: 30 seconds

Step-by-step explanation:

From the question, we are informed that one string flashes every 10 seconds while the other one string flashes every 15 seconds.

The number of minutes that it'll take before they both flash again at the same time will be gotten by calculating the LCM of 10 and 15. This will be:

10 = 10, 20, 30, 40, 50 ...

15 = 15, 30, 45, 60, 75 ....

We can see that the lowest common multiple of 10 and 15 is 30. Therefore, the answer is 30.

They'll both flash again at same time in 30 seconds.

Answer:

2.3×10/10=23/10=2 3/10 is mixed number

so basically, decimal points are tenths, hundredths, thousandths, etc. In this number, we have a digit in the ones place, and the tenths place. Decimals are based of 10. So, 0.3 would equal to 3/10, be it is 3 of 0.1 or 1/10. We cannot simply 3/10 because they only have a common factor of 1. So the final answer would be 2 3/10.

A shirt is on sale for $15.75. This is 15% off the original price. What was the original price of the shirt?

$18.11

$13.39

$17.25

$18.53

Answers

Divide sale price by (1 - percent of discount):

15.75 / (1- 0.15) =

15.75 / 0.85 = 18.53

Answer = $18.53

Answer:

18.53

Step-by-step explanation:

18.53*0.15≈2.7795

Rounded = 2.78

18.53-2.78=15.75

The value of Melissa's Jeep is $28,000 and is depreciating at a rate of 14% per year. Use an exponential function to find the value of the Jeep after 6 years. Round to the nearest cent. *

Answers

Answer:

$12,088

Step-by-step explanation:

Value = $28,000

Rate, r = 14% = 0.14

Time = 6 years

Using an exponential function :

A = Pe^-rt

P = initial value

A = final worth

A = 28000*e^-(0.14*6)

A = 28000 * e^-0.84

A = 28000 * 0.4317105

A = 12087.894

Worth after 6 years = $12,088

Janice has $2.30 made up of dimes, pennies and quarters. She has as many dimes as pennies and she has 17 coins in all. How many quarters does she have? (PLEASE HELP ME)

Answers

Answer:The equation would be 230 = 25y + 10x + 1x or 230 = 25y + 11x

You would then need to solve for x and y, which I forget how to do with 2 variables but since we're working with small numbers what I would do is continuously subtract 25 from 230 until the remainder is divisible by 11.

230 - 25*7 = 55 = 11*5

x = 5

Ok, adding the equation 2x+y = 17 you will now be able to solve for the two variables using a system of equations.

yes, you can come up with an equation. actually, you can come up several equations to generate a system of equations.

your first equation is correct.

(1) 25q + 10d + 1p = 230

now, you're told that the number of dimes equals the number of pennies. that just means, in symbols:

(2) d = p

finally, you're told that you have 17 coins in all, i.e.:

(3) q + d + p = 17

you now have three equations and three unknowns. use (2) to reduce (1) and (3).

(1′) 25q + 11d = 230

(3′) q + 2d = 17

now solve for the three variables.

Answer:

7 quarters

Step-by-step explanation:

We can use the guess method.

17 coins altogether, and as many dimes as pennies.

The number of quarters must be odd. When you subtract an odd number of quarters from 17, you get an even number which will divide by 2 evenly giving you the same number of pennies and dimes.

Start with a guess of 7 quarters.

17 - 7 = 10

7 quarters + 5 pennies + 5 dimes have a value of $2.30

Wow, I got it with the first guess.

Answer: 7 quarters

Lori bought some cookies for $2 each and muffins for $3 each. She bought twice as
many muffins as cookies and spent $16. How many cookies did Lori buy?

Answers

Answer:

2 cookies

Step-by-step explanation:

let c represent cookies, m represent muffins. set up a system of equations:

2c+3m=16

m=2c

(the top equation shows that cookies are $2 each, and muffins are $3, and that the total cost is $16. the bottom equation shows that Lori bought twice as many muffins as cookies).

then solve the system of equations by substitution, substituting 2c for m in the top equation:

2c+3(2c)=16

2c+6c=16

8c=16

c=2

this means that lori bought 2 cookies.

Answer:

2 cookies

Step-by-step explanation:

let c = no. of cookies

2c = no. of muffins

The cost for c cookies is 2c since each cookie was $2

and the cost of 2c muffins is 3(2c) = 6c since each muffing was $3

The total cost = 2c + 6c = 16

8c = 16

c = 2

So, she bought 2 cookies and 4 muffins

Step-by-step explanation:

You have to convert from a mixed number to a decimal. You can follow the following steps: To do this:

1.) You must divide the fraction's numerator by the denominator.

2.) You must now add the quotient obtained to the part of the Whole number.

you will get:

[tex]{\large\boxed{\fcolorbox{7}{\frac{1}{4}=7+0.25=7.25 }}[/tex]

The scale of the image that maps "Figure a" to "Figure b" is:

[tex]{\large\boxed{\fcolorbox{1:7.25}}[/tex]

3.) You have to multiply by 7.25 the length of the corresponding side of "Figure A" in order to find the value "x."

The final result will be:

Of those who like to fish, what percent are ages 13-18?

Answers

Answer:

B.) 42.9

Step-by-step explanation:

The percent that we are trying to find out is 12/28

I know this because if you add the 12 and 16 which is the total amount of people given then it leaves us with an amount of 28 people. Since we are trying to find the percent of the number of people who like fish we have to divide the total by 12 (the number of people who like fish)

Anyways 12 divided by 28 = 42.857etc.

If we simplify this then that gives us our answer of B.) 42.9

B. 42.9%

Which of the following describes one of the main obstacles Schwermer's lifestyle presents?Part of that philosophy requires her to put a lot of faith in the unknown. Other than the small notebook she uses to keep track of her scheduled speaking engagements and housing arrangements, most of her plans are left to fate. I see a lot of miracles in my daily life. For example, in the beginning I found food. I thought about things and then I found them in the street or people came to bring them to me, she explains. I think these miracles happen because of our thoughts. When seasons change, she gives away whatever clothing she has and waits for new items to come along. Most are given by hosts and friends she meets along the way. The road wasnt always easy. With two adult children and three grandchildren, Schwermer admits her family wasnt exactly on board when she pitched the idea. She now sees them only a few times per year, but says they eventually warmed up to her come-and-go lifestyle. Now theyre proud of what Im doing. Its enough for us, she says. Although she never had plans to go public with her life, after a German book publisher pushed her to put pen to paper, Schwermer relented. The latest of three books on her journey, Seeing Miracles In Life Without Money, will be released this summer in Germany. As with its predecessors, all her royalties4 will go to the various charitable groups she supports. Now, more and more young people want to change something in their lives and often they dont know what they can change, she says. I changed something in my life. Despite the legion of fans that have followed her for years, Schwermer has met her fair share of critics. After a trainwreck appearance on Italian talk show RAI TV, she stopped doing television interviews (in one taping, a host actually rifled through her suitcase).More often than not, however, its her friends who become frustrated with her come-and-go lifestyle. Shes turned down many invitations to extend her visits, including offers to stay permanently. There are so many people who are lonely and they like to have friends at their side, she says.
