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

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.

Answer:

Cory bought 6.474 gallons of gasolline.

Step-by-step explanation:

The total cost of gasoline ([tex]C[/tex]), measured in dollars, is given by the following expression:

[tex]C = n\cdot c[/tex]

Where:

[tex]n[/tex] - Amount of gasoline, measured in gallons.

[tex]c[/tex] - Unit cost, measured in dollars per gallon.

Given that [tex]C = \$\,18[/tex] and [tex]c = \$\,2.78\,\frac{1}{gal}[/tex], the amount of gasoline is cleared and calculated:

[tex]n = \frac{C}{c}[/tex]

[tex]n = \frac{\$\,18}{\$\,2.78\,\frac{1}{gal} }[/tex]

[tex]n = 6.474\,gal[/tex]

Cory bought 6.474 gallons of gasolline.

Answer:

Step-by-step explanation:

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:

[tex]P = \dfrac{1 - (\dfrac{1-p}{p} )^K}{1- (\dfrac{1-p}{p})^N } \ \ \ is \ p \neq 0.5 \ and\ K/N = \dfrac{1}{2}[/tex]

where ;

N.k = n  and k  = m

Hence, the probability changes to:

[tex]P = \dfrac{1 -(\dfrac{1-p}{p})^m}{1 -(\dfrac{1-p}{p})^{m+n}}[/tex] is  p ≠ 0.5   and k/N = [tex]\dfrac{m}{m+n}[/tex]  is P = 0.5

Answer:

4 and 15

Step-by-step explanation:

Let the two numbers be a and b.

The sum of the two is 19. Therefore:

[tex]a+b=19[/tex]

One number (let's use a) is 7 more than twice the other. Thus:

[tex]a=7+2b[/tex]

Solve for the system of equations. Substitute the second equation into the first:

[tex]a+b=19\\(7+2b)+b=19[/tex]

Subtract 7 from both sides:

[tex]2b+b=12[/tex]

Combine like terms:

[tex]3b=12[/tex]

Divide by 3:

[tex]b=4[/tex]

So, b is 4.

And since they add up to 19, this means that a is:

[tex]a+b=19\\a+4=19\\a=15[/tex]

So our numbers are 4 and 15

And we are done :)

Answer:

40000ftMSL

Step-by-step explanation:

We know that airspeed is measured using a pilot tube

And the air pressure is a function of density given as

Pressure= 1/2 xdensityx V²

So at 40,000ftMSL

Is this is replaced for V in the equation then the density of air will be 1/4 that of sea level

So since we are deriving velocity from pressure and pressure is 1/4 so the velocity Will be half of its pressure since velocity is squared from The equation above

Answer: 300 hrs

The time spent behind the wheel by the average Raleigh driver in 2016 is  300 hrs

Step-by-step explanation:

Given that;

Raleigh driver spent 18 hours in traffic jams

And it accounts for 6% of their total driving time

Now

let total driving time be = x hrs

so

6% of total driving time = 18 hrs

6/100 × x = 18hrs

6x = 1800 hrs

x = 1800/6

x = 300 hrs

∴ The time spent behind the wheel by the average Raleigh driver in 2016 is  300 hrs

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

Height of screen= 7.1 meters

Step-by-step explanation:

The growth factor is the base of the exponent: 0.98. Its relation to the rate of change is ...

  growth factor = 1 + rate of change

  0.98 = 1 + (-0.02)

So, the rate of change is -0.02 = -2%. Since the rate of change is a 2% decrease, it represents decay.

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.
