Aviation:
An airplane goes down from 42,000 feet to 18,000 feet in 12 minutes. What is the rate of change of the altitude in feet per minute?

Answer: b=p/r-z/r

Step-by-step explanation:

make sure the p/r is a fraction and so is z/r. p goes on top r goes on bottom, minus z over r

Answer:

Step-by-step explanation:

Quadrilateral EFGH is a rectangle.

Therefore, measure of all interior angle of the rectangle = 90°

7). m∠FEG + m∠GEH = 90°

    57° + m∠GEH = 90°

    m∠GEH = 90° - 57°

    m∠GEH = 33°

Diagonal of the rectangle are equal in measure and bisect each other.

8). m(FH) = m(FK) + m(KH)

               = 32 + 32 [Since, FK ≅ KH]      

               = 64

9). m∠FGH + m∠EFG = 90° + 90°

                                   = 180°

MNOP is a Rhombus, so the diagonals will be perpendicular and bisect each other.

10). m∠MRN = 90°

11). m(PR) = 12

    Therefore, m(RN) = 12

"Diagonals of a rhombus bisect the opposite angles"

12). m(∠PON) = 124°

   Therefore, m(∠POM) = 124°

"ABCD is an isosceles Trapezoid"

13). Therefore, ∠C ≅ ∠D

14). AB║CD

15). AD ≅ BC

Answer:

2.8- 4.4n- 2n + 7 = -6.4n + 9.8

Step-by-step explanation:

combined like term:

-4.4n - 2n = -6.4n

2.8 + 7 = 9.8

so all you do is combined together and got -6.4n + 9.8

i believe it equals 9.8-6.4n

Answer:

12, 17

Step-by-step explanation:

Let the two positive integers be x and (5 + x).

According to the given description:

[tex] {x}^{2} + {(x + 5)}^{2} = 433 \\ {x}^{2} + {x}^{2} + 10x + 25 = 433 \\ \\ 2 {x}^{2} + 10x + 25 - 433 = 0 \\ \\ 2 {x}^{2} + 10x - 408 = 0 \\ \\ 2( {x}^{2} + 5x - 204) = 0 \\ \\ {x}^{2} + 5x - 204 = 0 \\ \\ {x}^{2} + 17x - 12x - 204 = 0 \\ \\ x(x + 17) - 12(x + 17) = 0 \\ \\ (x + 17)(x - 12) = 0 \\ \\ x + 17 = 0 \: or \: x - 12 = 0 \\ \\ x = - 17 \: or \: x = 12 \\ \\ \because \: x \: is \: a \: + ve \: integer \\ \\ \implies x \neq - 17 \\ \\ \therefore \: x = 12 \\ \\ 5 + x = 5 + 12 = 17 \\ [/tex]

Thus, the two positive integers are 12 and 17.

Answer:

[tex]sin 54 = \frac{x}{14}[/tex]

Step-by-step explanation:

[tex]sine = \frac{opposite}{hypotenuse}[/tex]

Side z is the adjacent, since it is next to the angle you are solving for.

Side x is the opposite, since it is opposite the angle you are solving for.

The side measuring 14 is the hypotenuse, since it is across from the right angle.

Answer: 40%

Step-by-step explanation:

A p e x

Answer:

40% A.

Step-by-step explanation:

Answer:

h=0.6m

r=0.75m

h=0.6m/0.75m*100 percent of r.

h=6000/75% of r

h=80% of r

Step-by-step explanation:

The expression of h as a percentage of r would be as;  80% of r.

A percentage is a minimum number or ratio that is measured by a fraction of 100.

WE are given that h is 60% of m.

Also, r is 75% of m.

WE need to find out h as a percentage of r.

Therefore, h=0.6m

r=0.75m

Now we can write as;

h = 0.6m/0.75m x 100 percent of r.

h = 6000/75% of r

h = 80% of r

Hence, the expression of h as a percentage of r would be as;  80% of r.

Answer:

Angle 3 is 95, angle 1 is 30.

Step-by-step explanation:

I already answered a lot of your other angle questions so I will make this one QUICK...

Angle 4 is 85, so to find angle 3, simply subtract: 180 - 85 = 95

So angle 3 is 95

We know two out of the three angles in a triangle and they are: 95 and 55, so 95 + 55 = 150. The sum of the angles in a triangle is 180 so we have: 180-150 = 30, which is the answer for angle 1.

So angle 1 is 30

Cylinder's volume = 1330.5 cm^3

Step-by-step explanation:

radius, r = diameter, d / 2

= 5.5 cm

Volume = π r^2 h

= π × 5.5^2 × 14

= 423.5π

= 1330.5 cm^3

31m2−30.2m+4.9

Step-by-step explanation:

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

The equivalent expression to 2.2m² – 3.5(4m – 1.4) + 3.6(8m² – 4.5m) is

31m² - 30.2m - 4.9

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

2.2m² – 3.5(4m – 1.4) + 3.6(8m² – 4.5m)

Remove the parenthesis.

2.2m² - 3.5 x 4m - 3.5 x 1.4 + 3.6 x 8m² - 3.6 x 4.5m

2.2m² - 14m - 4.9 + 28.8m² - 16.2m

Combine the like terms.

31m² - 30.2m - 4.9

Thus,

The equivalent expression to 2.2m² – 3.5(4m – 1.4) + 3.6(8m² – 4.5m) is

31m² - 30.2m - 4.9
