The distance between the two men is 7.2 ft. That is, they are 7.2 ft apart

From the question, we are to determine the distance between the two men

Let the distance between the men be x

From the given information,

The man of the diving board is 6 ft tall

and

The angle of elevation from the man in the water to the man on the diving board is 40°

Considering the triangle formed, we can write that

Opposite = 6 ft

Adjacent = x

Angle = 40°

From SOH CAH TOA, we have that

tan (angle) = opposite / adjacent

∴ tan 40° = 6 / x

x = 6 / tan 40°

x ≈ 7.2 ft

Thus,

The men are 7.2 ft apart

By means of vector sum and Pythagorean theorem, the line segment BC has a length of 5 units.

We find a line segment whose endpoints are known and set on Cartesian plane, the length of the line segment must be found by means of vector sum and Pythagorean theorem. First, determine the vector associated to the line segment:

[tex]\overrightarrow {BC}[/tex] = C(x, y) - B(x, y) = (0, 2) - (- 3, - 2) = (3, 4)

Second, determine the magnitude of the vector derived in the previous step:

Answer:

4 x 10^7 i.e. 40000000

Step-by-step explanation:

(4x10^7) is obtained by multiplying (5x10^2) by (8x10^4).

The equation can be solved by multiplying the coefficients (5 and 8) first, adding the exponents (2 and 4), and writing the result in scientific notation:

(5 x 8) x 10^(2 + 4) = 40 x 10^6 = 4 x 10^7.

In this Triangle, ΔUVW, UW is extended through point w to point x

∠ WUV = (3x - 4)°

∠ VWX = (6x + 6)°

∠ UVW = (x + 20)°,  

the value of x is 5

According to the question, given that

∠ WUV = (3x - 4)°

∠ VWX = (6x + 6)°

∠ UVW = (x + 20)°

because ∠ VWX = ∠ WUV + ∠ UVW

             ⇒  (6x + 6) = (3x - 4) + (x + 20)

             ⇒  (6x + 6) = 4x + 16

             ⇒ 2x = 10

             ⇒ x = 5

{The sum of triangle's interior angles is 100°}

{The sum of supplementary angles is 180°}

Therefore, In ΔUVW, UW is extended through point w to point x, then the value of x is 5.

The interior angles of a triangle always add up to 180° while the exterior angles of a triangle are equal to the sum of the two interior angles that are not adjacent to it. By deducting the angle of the target vertex from 180°, one can also determine a triangle's exterior angle.

When a family's ratio of income to poverty measurement is 1.05 , then the family is considered by the census bureau as rich.

The "economy food plan," which is based on the U.S. Department of Agriculture, is used as the basis for an absolute poverty indicator in the country. The World Bank also uses an absolute definition of poverty. Extreme poverty is defined as surviving on less than $1.90 USD a day.

A ratio of less than 1 generally indicates that the income is below the poverty line. When the ratio is 1, income and poverty level are equal, and when the ratio is larger than 1, income is greater than poverty level. In this case, the family is rich.

Check the picture below.

The mass of ingredient is given by 66g, 45g, 100g, 150g.

What is mass?

Mass is a parameter of measurement that calculates how much matter is contained in a body.

Mass is a physical quantity. Mass is measured in terms of the weight of a body. Gram, kilogram, and pounds are some standard mass units to measure it. The SI unit of mass is the kilogram; however, smaller objects are measured in grams.

Given, the ratio of the ingredients by mass as 2:2:1.

Let x be the mass of the ingredients.

A) total mass is given by 330g

therefore, 2x+2x+1x = 330

5x = 330

x = 330/5

x = 66

Hence the mass of oat = 2(66) = 132g

mass of cereal = 2(66) = 132 g

mass of nuts = 66g

B) 2x+2x+1x = 210

5x = 210

x = 210/5

x = 42g

Hence,  the mass of oat = 2(42) = 84g

mass of cereal = 2(42) = 84 g

mass of nuts = 84

C) 2x+2x+1 = 500

5x = 500

x = 100

hence,  the mass of oat = 2(100) = 200g

mass of cereal = 2(100) = 200 g

mass of nuts = 100g

D) 2x+2x+1 = 750g

5x = 750

x = 750/5

x = 150

Hence, the mass of oat = 2(150) = 300g

mass of cereal = 2(150) = 300 g

mass of nuts = 150g

Answer:

22x + 4y + 13xy

Step-by-step explanation:

First, you add the like terms

(the terms that contain the same variable which is raised to the same power)

6x + 5x + 11x= 22x

2y + 2y = 4y

13xy

Then since nothing else shares the like terms you leave it as 22x + 4y + 13xy

The interval of x-values over which the function is increasing is (-3 , -1)

A law that connects two variables—the dependent and the independent variables—is known as a function.

A function's range and domain are always specified.

The x and y values are:

-6      -34

-5       3

-4      -10

-3      -11

-2      -6

-1        -1

0        -2

1        -15

It is necessary to identify the range of x-values across which the function increases.

The function is not rising in this interval, hence the first option is (-6, -3).

The function is rising in this range, hence the second alternative is (-3, -1).

The function is not rising in this interval, hence the third alternative is (-3, 0).

The function is not rising in this period, hence the fourth alternative is (-6, -5).

By taking some products between fractions and mixed numbers, we will see that your trip along the bank has a length of (2 and 9/24) miles.

Here we know that the total distance of the travel is (14 + 1/4) miles.

In this case, we know that 1/3 of that distance is traveled in the woods, so the total distance traveled in the woods is given by the product:

D = (1/3)* (14 + 1/4) mi = (14/3 + 1/12) mi

Now we know that 1/2 of the distance traveled in the woods is traveled along the bank of a strem, then the distance that we are looking for is given by the product:

D' = (1/2)*(14/3 + 1/12) mi = (7/3 + 1/24)mi

Now we can simplify that mixed number as:

(7/3 + 1/24)mi = (6/3 + 1/3 + 1/24) mi = (2 + 8/24 + 1/24)mi = (2 + 9/24) mi

Missing side length of the given measures of the triangle is equal to           x = 1/2 units (approximately).

As given,

Given measures of the triangle ABC are

Angle A=(18 +18)°

             =36°

Consider side opposite to ∠A=a ,∠B=b ,∠C=c

Given side length

AC=b

     =20

AB=c

    =12

BC=c

    =x+12

Using cosine law

cos A= (b²+c²-a²)/2bc

⇒cos36°= [20²+12²-(x+12)²]/2(20)(12)

⇒(1+√5)/4=(544-x²-24x-144)/480

⇒x²+24x-280+120√5=0

⇒x²+24x-11.7=0

Now, x = [-24±√24²-4(1)(-11.7)]/2(1)

           = (-24±24.955)/2

           ≈ (-24 ±25)/2

Answer:

B

Step-by-step explanation:

To find the number of extra flowers ordered, we can start by forming an equation based on the total amount paid by the customer.

Let the number of extra flowers be n.

Total paid

= cost of standard arrangement +(number of extra flowers)(cost per additional flower)

= $25 +n($1.25)

Given that the customer paid $45,

25 +1.25n= 45

Now that we have formed the equation, let's solve for n.

Subtract both sides by 25:

1.25n= 45 -25

1.25n= 20

Divide both sides by 1.25:

n= 20 ÷1.25

n= 16
