The set notation of the numbers is {x | x < 50 ∪ x > 50}

The set is given as

The set of all real numbers less than 50 or greater than 50

Let the number be represented by x

So, we have

x less than 50 or x greater than 50

When represented as an inequality, we have

x < 50 or x > 50

Using set notation, we have

{x | x < 50 ∪ x > 50}

Hence, the set notation of the numbers is {x | x < 50 ∪ x > 50}

Answer:

Step 1. The perimeter P means adding up all four sides of a rectangle.

Step 2. Let w be the width

Step 3. Let 3w be the length since the width is one-third the length

Step 4. Then P=w+w+3w+3w=8w=20 since the perimeter P is 20 cm.

Step 5. Solving the equation in Step 4 leads to the following steps

Divide by 8 to both sides of the equation

8w%2F8=20%2F8

w=5%2F2 and 3w=15/2 and P=2(5/2+15/2)=20 which is a true statement.

Step 6. ANSWER: The width is 5/2 cm.

The systolic pressure, to the nearest tenth of a millimeter, for a person of age 41 years is; 133.6 mm Hg

We are given the equation that gives a person's blood pressure, p at the age y year is;

p = 0.007y² - 0.003y + 122

To find the systolic pressure for a person of age 41 years, just plug in y = 41 into the given quadratic equation to get;

p(41) = 0.007(41)² - 0.003(41) + 122

p(41) = 11.767 - 0.123 + 122

p(41) = 133.6

Thus, the systolic pressure, to the nearest tenth of a millimeter, for a person of age 41 years is; 133.6

In which k is the constant of proportionality.

For this problem, looming at the table, we have that the number of Broccoli is triple the number of carrots, hence the proportional function is:

B = 3C.

When there is one carrot, the number of broccoli is given by:

The triangles are subject to this law. If another number were present, their sum would always be greater than 180 degrees.

It is defined as the branch of mathematics that is concerned with the size, shape, and orientation of two-dimensional figures.

It is given that:

In Euclidean geometry, the interior angles of any triangle add up to 180 degrees.

As we know,

Spherical trigonometry, which departs from conventional trigonometry in many ways, is created when angles between great circles are defined.

For instance, the total of the sides and angles of a hemispheric triangle is more than 180 degrees.

In spherical geometry, triangles are subject to this law. If another number were present, their sum would always be greater than 180 degrees.

Thus, the triangles are subject to this law. If another number were present, their sum would always be greater than 180 degrees.

Value of x for the given data sin(3x-35)°-cos(x+20)°=0, where x is an acute angle is equal to 8.75°.

As given in the question,

Given data :

sin(3x-35)°-cos(x+20)° = 0     __(1)

As we know  x is an acute angle  ,

cos (90 - α)° =sinα°

⇒ sin (3x -35)° =cos (90 -(3x - 35))°

⇒ sin (3x -35)°=cos (55 -3x )° ___(2)

Substitute the value of sin (3x -35)° from (2) to (1),

cos(55 -3x)° -cos(x+20)°=0

⇒cos(55 -3x)° =cos(x+20)°

⇒55 -3x=x+20

⇒x=8.75°

Therefore, value of x for the given data sin(3x-35)°-cos(x+20)°=0, where x is an acute angle is equal to 8.75°.

The first flight is 2 hours and second flight is 2 hours and 48 minutes

The two distances are the same (out and back),

so set them equal.

That distance is cover by having one is (rate)(time) equal to other is (rate)(time).

Let,

One time is “x” and the other is “4.8-x.”

One average rate  is 460 per hour

and the other average rate is 500 per hour.

we know , Speed = [tex]\frac{distance}{time}[/tex]

so , distance = speed × time

put in this formula we get the value of X

⇒460 x = 500 (4.8 -x)

⇒460 x = 2400 - 500x

⇒900 x = 2400

⇒x = 2.5 hours for the slower plane.

⇒4.8- x = 2.3 hours for the faster plane.

The formula speed = distance ÷ time can be rearranged, just like any other equation.

Here detail explanation about relation between speed distance and time :

The formula can be rearranged in three ways:

Marty will have to pay $18,000 for his $15,000 car.

While taking out a loan, the amount taken has to be repaid along with an interest. Thus, the amount paid back by the borrower is always greater than the initial amount that the borrower gets from the lender as a loan.

Here, we are given that Marty has to pay $500 per month for 3 years to repay the loan for his $15,000 car.

Thus, for one month he pays = $500

and also we know that 1 year = 12 months

⇒ 3 years = 12(3) = 36 months

Therefore, for 36 months Marty will have to pay,

500 × 36 = 18,000

The answer is that 80 people will build the same road in 160 days.

Given that 50 people take 256 days to build a road.

And we need to find out how many days will 80 people take to build the same road.

Disclaimer: Assuming that the work done by all the people are same.

If the number of people increases, the time taken to build the road decreases in the same proportion. Clearly, the number of people varies inversely to the number of days.

Let x denote the number of days required to build the road for 80 people.

Then the ratio, 80/50 = 256/x

⇒ x = (256×50)/80 = 160

Therefore, 80 people will build the same road in 160 days.

The number of feet the submarine ascended is the same as the number of feet f below sea level.

A number line is a straight line with a zero point in the middle and positive and negative numbers listed on either side of zero and going on indefinitely.

We have,

The submarine is at feet f below sea level.

We represent the distance below sea level by a negative number.

We represent ascended by a positive number.

So the distance traveled by submarine is:

= Distance below sea level + Distance ascended

= (-f) + distance ascended

We have,

The submarine ascended to 0 feet above sea level.

This means,

The distance traveled by submarine = 0

Distance below sea level + Distance ascended = 0

(-f) + Distance ascended = 0

Distance ascended = f

Thus the number of feet the submarine ascended is same as the number of feet f below sea level.

Step-by-step explanation:

Given:

[tex]\begin{aligned} \textsf{Net Asset Value}_{\textsf{(Per Share)}} & =\dfrac{\textsf{Fund Assets}-\textsf{Fund Liabilities}}{\textsf{Total number of Outstanding Shares}}\\\\\implies \textsf{Net Asset Value}_{\textsf{(Per Share)}} & = \dfrac{\$39,400,000-\$3,940,000}{\$1,380,000}\\\\& = \dfrac{\$35,460,000}{\$1,380,000}\\\\& = \$25.69565217...\\\\\end{aligned}[/tex]

Therefore, the Net Asset Value (NAV) per share is $25.70 (nearest cent).

The given information is,

→ x = $39,400,000

→ y = $3,940,000

→ z = 1,380,000

Formula we use is,

→ (x - y)/z

Now the net asset value per share is,

→ (x - y)/z

→ (39400000 - 3940000)/1380000

→ 35460000/1380000

→ 25.6956521739

→ ≈ $25.70

Hence, the net asset value is $25.70.
