Answer:

Length = 25 meters

Width = 6 meters

Step-by-step explanation:

62 = 2(a+b)

a = 4b + 1

a = length

b = width

then:

62 = 2((4b+1)+b)

62/2 = 4b+b+1

31 = 5b + 1

31 - 1 = 5b

30 = 5b

b = 30/5

b = 6m

a = 4b + 1

a = 4*6 + 1

a = 24 + 1

a = 25m

Check:

62 = 2(6+25)

62 = 2*31

The correct answer would be 54 hundreds

Step-by-step explanation:

If we are considering how many hundreds something has, we can simply take away two 0's and use that number.  We take the two 0's off and then we have the right number of hundreds

Answer:

Hey there!

Five-thousand four-hundred can be expressed as fifty-four hundred.

Answer:

  y = x

Step-by-step explanation:

The slopes of parallel lines are the same, so we know the equation will be ...

  y = x + constant

We can find the constant by using the given point's values for x and y:

  2 = 2 + constant

Obviously, the constant is zero.

The equation of the parallel line through (2, 2) is y = x.

Answer:

Your friends data

Step-by-step explanation:

The rule of statistics is: the more exact the data, the better.

It looks like you just rounded your data to the nearest tenth. This is good, but not nearly as good as rounding it to the nearest hundredth.

This is because when you have data that is more exact, you get a better estimation for mean, median, etc. This can help make patterns in your data.

This means that your friend had better data than you.

Hope this helped!

Answer:

I believe the correct answer is C.

Step-by-step explanation:

So to get 0 solutions the absolute value would have to equal a negative number. To get 1 solution the absolute value would have to equal 0. To get 2 solutions the absolute value would have to equal a positive number.

2 |x - 1| = 8

divide by 2

|x - 1| = 4

The absolute value equals a positive so it has 2 solutions.

Answer:

( x - y ) ( a - b ) = -1

Step-by-step explanation:

ax + by = c  and  bx + ay = 1 + c

ax + by = c  and  bx + ay - 1 = c

And now we set c equivalent

ax + by = bx + ay - 1

ax - bx + by - ay = -1

x (a - b) + -y (a - b) = -1

(x - y) ( a - b) = -1

So we can leave it like that, or we can solve for one of the variables.

If we solve for y:

(x - y) ( a - b) = -1

(x - y) = -1 / (a - b)

-y = (-1 / (a - b)) - x

y = (1 / (a-b)) + x

Answer:

The positive value of k that the function y = sin(kt) satisfies the differential equation y'' + 144y = 0 is +12

Step-by-step explanation:

To determine the positive values of k that the function y = sin(kt) satisfy the differential equation y''+144y=0.

First, we will determine y''.

From y = sin(kt)

y' = [tex]\frac{d}{dt}(y)[/tex]

y' = [tex]\frac{d}{dt}(sin(kt))\\[/tex]

y' = kcos(kt)

Now for y''

y'' = [tex]\frac{d}{dt}(y')[/tex]

y'' = [tex]\frac{d}{dt}(kcos(kt))[/tex]

y'' = [tex]-k^{2}sin(kt)[/tex]

Hence, the equation y'' + 144y = becomes

[tex]-k^{2}sin(kt)[/tex] + [tex]144(sin(kt))[/tex] [tex]= 0[/tex]

[tex](144 - k^{2})(sin(kt)) = 0[/tex]

[tex](144 - k^{2})= 0[/tex]

∴ [tex]k^{2} = 144\\[/tex]

[tex]k =[/tex] ±[tex]\sqrt{144}\\[/tex]

[tex]k =[/tex] ± [tex]12[/tex]

∴ [tex]k = +12[/tex] or [tex]-12[/tex]

Hence, the positive value of k that the function y = sin(kt) satisfies the differential equation y'' + 144y = 0 is +12

The positive value of k that satisfies the differential equation is k = 12.

To find the value of k that satisfies the equation, we differentiate the function y = sin(kt) twice to obtain y" and we insert it into the differential equation y" + 144y = 0.

So, y' = dy/dt

= dsin(kt)/dt

= kcos(kt)

y" = dy'/dt

y" = dkcos(kt)/dt

y" = -k²sin(kt)

So, substituting y and y" into the differential equation, we have

y" + 144y = 0

-k²sin(kt) + 144sin(kt) = 0

-k²sin(kt) = -144sin(kt)

k² = 144

k = ±√144

k = ±12

Since we require a positive value, k = 12

So, the positive value of k that satisfies the differential equation is k = 12.

Answer:

Rachel has 27

Hong has 51

Manuel has 17

Step-by-step explanation:

Let R represent Rachel, H represent Hong, and M represent Manuel.

They combined have a total of 95. Thus:

[tex]R+H+M=95[/tex]

Hong has 3 times what Manuel has. Therefore:

[tex]H=3M[/tex]

Rachel has 10 more than Manuel. Therefore:

[tex]R=10+M[/tex]

Substitute:

[tex]R+H+M=95\\(10+M)+(3M)+M=95[/tex]

Combine like terms:

[tex]5M+10=95[/tex]

Subtract 10 from both sides:

[tex]5M=85[/tex]

Divide by 5:

[tex]M=17[/tex]

Therefore, Manuel has 17.

Now, find Rachel and Hong's money.

[tex]H=3M\\H=3(17)=51[/tex]

So, Hong has 51.

And for Rachel:

[tex]R=10+M\\R=10+17=27[/tex]

Rachel has 27.

Answer:

Yes, it means that both of you obtain a result with the same precision and accuracy.

Step-by-step explanation:

It is provided that two different people took measurements in order to find the length of a rod.

The first person took 30 measurements.

The second person took 20 measurements.

Both the people got the same average length, i.e. L₀.

In statistics, a larger sample leads to an error free result.

So, for the first person the larger sample helped reducing the chance of any sort of error that may be present.

For the second person, the average is same as the first even when their sample size is less than the first.

This may happen because the sample was selected with a certain precision and accuracy.

Thus, both of them obtain a result with the same precision and accuracy.

Answer:

Approximately

Height of screen= 7.1 meters

Step-by-step explanation:

Angle of elevation= 18°

Angle of depression= 58°

Distance of Goran from screen= 5 m

Height of screen from the attachment below

X+y

First let's determine angle a and b

a= 180-90-18

a= 72°

b= 180-90-48

b= 43°

Using sine formula

5/sin a= x/sin 18

5/sin 72= x/sin18

(5*sin 18)/sin 72= x

1.6246 = x

X= 1.6246 m

Y/sin 48= 5/sin b

Y= (5*sin 48)/sin 43

Y= (5*1.08965779)

Y= 5.4483 m

Height of screen= x+y

Height of screen= 1.6246+5.4483

Height of screen= 7.0729

Approximately

From the given information,

Considering both cases when p = 0.5 and when p ≠ 0.5

the probability that the gambler will quit an overall winner is:

Answer:

44,000

Step-by-step explanation:

The number 43,761 rounded to its nearest thousands is 4400.

The place value of a number is given as:

Example:

1234.567

1 = thousand place value

2 = hundred place value

3 = tens place value

4 = ones place value

5 = tenths place value

6 = hundredths place value

7 = thousandths place value

We have,

43,761

3 is in the thousand place.

So,

We will round 3761 to its nearest thousand value.

There are two options:

3000 or 4000

If It is greater than 3499 it will round to 4000.

If it is less than 3500 it will round to 3000.

Now,

3761 > 3499.

So,

The number is rounded to 4000.

Thus,

43,761 is rounded to 4400.
