Answer:

At 5:15 PM , they will ring together.

Step-by-step explanation:

We have been given that first bell rings every 15 minutes and second bell rings at every 25 minutes.

In order to find when both will ring together again, we can find the LCM of these two numbers.

15 = 3 × 5

25 = 5 × 5

Therefore, LCM of these two numbers is

LCM = 5 × 5× 3

LCM = 75

Hence, 75 minutes = 75/60 = 5/4 hours

Therefore, at 5:15 PM , they will ring together.

At 5:15 PM the clocks will ring together.

In mathematics, the least common multiple is sometimes referred to as LCM or the lowest common multiple. The smallest number among all the common multiples of the provided numbers is the least common multiple of two or more numbers.

Given:

A clock is set to ring every 15 minutes whereas another clock is set to ring every 25 minutes.

In order to find when both will ring together again, we have to find the LCM of  25 and 15 as

15 = 3 × 5

25 = 5 × 5

LCM (25, 15) = 5 × 5× 3

                     = 75 min

                     = 1 hour 15 minutes.

Hence, At 5:15 PM the clocks will ring together.

Step-by-step explanation:

The area of the walkway will be 96 square feet. The correct option is C.

The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the rectangle in a two-dimensional plane is called the area of the rectangle.

Given that the dimensions of the crosswalk are,

19 feet

5 feet

The area of the cross-walk will be calculated as below,

Area = Length x Width

Area = 19 x 5

Area = 96 square feet

Therefore, the area will be equal to 96 square feet.

The equation is;

3(x + 0.75) = 5.88

The original price is $1.21

Step-by-step explanation:

Let the original price per pound be $x

By going up, the new price will be;

(x + 0.75)

3 times this is the new price;

3(x + 0.75) = 5.88

3x + 2.25 = 5.88

3x = 3.63

x = 3.63/3

x = $1.21

P × R × T ÷ 100

333,500 × 8% ×24 ÷ 100

64,032,000÷100

640,320

The amount of profit would the company make over the course of its first 24 years of operation should be $2,114,784.

Since annual profit is $333,500

The profit percentage should be likely 8%

And, the number of years should be 24

So, the amount of profit should be

[tex]= $333,500 * (1 + 0.08)^{24[/tex]

Answer:

All you have to do is replace p with 5, and see if it works. In this case it doesn't because 5+13 does not equal 21.

Answer:

Not a solution

Step-by-step explanation:

You would plug 5 into the equation where it says p. If 5+13=21, then it is a solution. If it equals to something different, then it is not a solution. In this case, it adds up to 18, making it not a solution.

Answer:

#2 is 2^-9.  #3 is 1/6^15. #4 is 10^8.

Step-by-step explanation:

Remember that with exponents, division is subtraction, and multiplcation is addition.

So for the first problem, 2^-5 / 2^4 is really:

2^-5-4

This is simply 2^-9 power.

Next we have (6^-3)^5. I dont mean to confuse you, so just remember. When, and ONLY when and exponent is INSIDE parentherse, can it be multplilied by another exponent that is OUTSIDE of the parenthesese. SO we can write this as:

6^-3*5

This equals:

6^-15

Which can further be simplyfied to:

1/6^15

Countinuing on we have 10^-12 / 10^-20. Since we are dividing, we subtract to exponenets. So we can write this as:

10^-12 - -20

This is just 10^8 power.

Hope this helps! :)

Answer:

x is 13.03

Step-by-step explanation:

Start by determining the length of the horizontal side of one of the triangles shown.  The Pythagorean Theorem applies here:

(horizontal side)² + 17² = 19², so that:

(horizontal side)² + 17² = 19² - 17², or 72

Then the length of the horizontal side is +√72, or √36√2, or 6√2.

From the diagram it is obvious that the width of the rectangle, x, can be found by subtracting twice the length of the horizontal side of one of the triangles from 31 (base of the entire figure):

x = 31 - 2(6√2) = 13.03

x is 13.03

Step-by-step explanation:

You understand the question, and already have the numbers in order, you're almost there!

So you need to find the median first so you can divide the data set into the upper and lower halves. The median, as you probably know, is the center of the data. What I do for this is list all the numbers out in order, like you've already done, and start crossing them out, one at a time, alternating the sides. I'll show you what I mean. (I'm using underline because there's no strikethrough.)

52, 54, 55, 55, 57, 58, 59, 59, 61, 61, 61, 62, 63, 63, 64, 65, 65, 68, 70, 72

52, 54, 55, 55, 57, 58, 59, 59, 61, 61, 61, 62, 63, 63, 64, 65, 65, 68, 70, 72

52, 54, 55, 55, 57, 58, 59, 59, 61, 61, 61, 62, 63, 63, 64, 65, 65, 68, 70, 72

52, 54, 55, 55, 57, 58, 59, 59, 61, 61, 61, 62, 63, 63, 64, 65, 65, 68, 70, 72

52, 54, 55, 55, 57, 58, 59, 59, 61, 61, 61, 62, 63, 63, 64, 65, 65, 68, 70, 72

...and so on, until you have:

52, 54, 55, 55, 57, 58, 59, 59, 61, 61, 61, 62, 63, 63, 64, 65, 65, 68, 70, 72

Because there's an even number of numbers, the median is the mean of the middle two numbers. Luckily, though, the two numbers in the middle are the same:61. Mean is calculated by adding the terms and dividing by the number of terms. In this case:

(61+61)/2

=61

(You didn't really have to do this mean step, but I'll explain later.)The median is 61. Another way you could have done this is by just counting the number of terms (20) and finding the middle one. Again, since there's no middle one, you'd have to find the mean.

Since you're looking for the third quartile and not the median, you didn't exactly have to do that step. I just wanted to explain how to calculate the median, since you'll have to do it in the next step. All we had to do here was divide the data set into the halves, so we used that visual demonstration by underlining the numbers one at a time. We didn't have to find the mean, we could have split the set down the middle instead.

52, 54, 55, 55, 57, 58, 59, 59, 61, 61, | 61, 62, 63, 63, 64, 65, 65, 68, 70, 72

                                                             ^median/half-way point

We could have also divided the number of terms (20) by 2 (because halves, 2 parts) to get 10 and used the upper 10 values of the set, but I don't know, the crossing out method helps me. Anyway, now we have to look at just the upper 10 values:

61, 62, 63, 63, 64, 65, 65, 68, 70, 72

And you repeat the process! (I'm not going to show the underlining though lol)

There are 10 terms, so the median is between the 5th and the 6th. (10/2=5)

61, 62, 63, 63, 64, 65, 65, 68, 70, 72

This is what I was talking about, there are an even number of values in the upper half of the data set as well, so we have to find the mean of the middle 2: 64 and 65.

 (64+65)/2

=129/2

=64.5

That's your final answer. Hope I could help you!

Answer:

x = 60

y = 50

Explanation:

in a triangle, the sum of all its angles should be 180°. so, to find x, we can subtract the known values from 180° like this:

180° - 50° - 70° = 60°

thus, x is 60.

using the same method, we can find the remaining angle of the other triangle:

180° - 50° - 60° = 70°

now, we know the values of x and the angle next to it. on a straight line, the sum of angles also adds up to 180°. therefore:

180° - 60° - 70° = 50°

Answer:

5/9

Step-by-step explanation:

Let the denominator be x and numerator be y.

Given, numerator is 4 less than denominator

=> y = x - 4 ...(1)

When 5 is added to both:

Numerator = y + 5 , and, denominator = x + 5

Now their ratio is 5/7.

=> (y + 5)/(x + 5) = 5/7

=> 7(y + 5) = 5(x + 5)

=> 7y + 35 = 5x + 25

=> 7y - 5x = 25 - 35

=> 7(x - 4) - 5x = -10 {y=x-4}

=> 7x - 28 - 5x = -10

=> 2x = 18

=> x = 9

Thus,

Fraction is y/x = (x-4)/x = (9-4)/9 = 5/9
