A plane flew 390 nautical miles in 45 min. Find its average speed in knots ( nautical miles per hour)

Answers

Answer:

451.87 knots.

Step-by-step explanation:

Hope this helps

The average speed of the plane is 520 Knots.

What is the speed of an object?

Speed is the rate at which an object's position changes, measured in meters per second. For example, if an object starts at the origin, and then moves three meters in three seconds, its speed is one meter per second. The equation for speed is simple: distance divided by time

Given here: Distance travelled 390 nautical miles and t is 45 mins or 0.75 hours

Thus speed of the plane is = 390/0.75

= 520

Hence, The average speed of the plane is 520 Knots.

a³+b³ if a+b=3ab=2
please help me

Answers

Answer:

[tex]a^3 + b^3 = -4[/tex]

Step-by-step explanation:

Given

[tex]a + b = 3ab = 2[/tex]

Required

Solve: [tex]a^3 + b^3[/tex]

Rewrite the expression as:

[tex]a^3 + b^3 = a^3 - a^2b +ab^2 + a^2b - ab^2 + b^3[/tex]

Factorize

[tex]a^3 + b^3 = a(a^2 - ab +b^2) + b(a^2 - ab + b^2)[/tex]

[tex]a^3 + b^3 = (a + b)(a^2 - ab + b^2)[/tex]

Rewrite as:

[tex]a^3 + b^3 = (a + b)(a^2 + b^2- ab)[/tex]

[tex]a^3 + b^3 = (a + b)(a^2 + b^2+2ab - 3ab)[/tex]

Factorize

[tex]a^3 + b^3 = (a + b)((a + b)^2 - 3ab)[/tex]

Open brackets

[tex]a^3 + b^3 = (a + b)^3 - 3ab(a + b)[/tex]

Given that:

[tex]a + b = 3ab = 2[/tex]

This means that:

[tex]a + b = 2[/tex] and [tex]3ab = 2[/tex]

So, we have:

[tex]a^3 + b^3 = (a + b)^3 - 3ab(a + b)[/tex]

[tex]a^3 + b^3 = 2^3 - 3 * 2 * 2[/tex]

[tex]a^3 + b^3 = 8 - 12[/tex]

[tex]a^3 + b^3 = -4[/tex]

(30)(-80)−50=50−(30)(-80)

Answers

Answer:

Below

Step-by-step explanation:

False, negative times negative is always positive.

True, 10,000 is less than 99,999, so subtracting them will be negative.

False, 34 and 43 aren't equal to eachother so subtracting them can't end up to 0.

False. If you follow PEMDAS, you have to do multiplication first. In the left side, -80(30) is a negative value, while in the right, (-30)(-80) is a positive value.

Find g[h(x)] and h[g(x)] of the functions g(x)=x^2-7 and h(x)=3x+2

= 9x² + 6x + 6x + 4 - 7

= 9x² + 12x - 3

h(g(x)) = 3(x² - 7) + 2

the answer is 28

Answer:

Step-by-step explanation:

According to Order of Operations rules, we must multiply here before adding or subtracting.

In 7 +6 - 9(-2) + (-3) the very first thing we must do is to evaluate the product -9(-2). This comes out to 18, so now we have:

7+6 + 18 +(-3).

Next, remove the remaining parentheses, obtaining:

The polynomial V(x)=x^2+9x^2-16x-144 represents volume of a shipping crate. Explain how to find the area of the base of the crate? if the polynomial H(x)=x+4 represents the height of the crate

Answers

Answer:

x = − 9 , − 4 , 4

Step-by-step explanation:

Each crate is in the shape of a rectangular solid. Its dimensions are length, width, and height. The rectangular solid shown in the image below has a length

4 units, width 2 units, and height 3

units. Can you tell how many cubic units there are altogether? Let’s look layer by layer.

Breaking a rectangular solid into layers makes it easier to visualize the number of cubic units it contains. This

4 by 2 by 3 rectangular solid has 24 cubic units.

A rectangular solid is shown. Each layer is composed of 8 cubes, measuring 2 by 4. The top layer is pink. The middle layer is orange. The bottom layer is green. Beside this is an image of the top layer that says

Altogether there are 24 cubic units. Notice that 24 is the length × width × height.

The top line says V equals L times W times H. Beneath the V is 24, beneath the equal sign is another equal sign, beneath the L is a 4, beneath the W is a 2, beneath the H is a 3.

The volume, V, of any rectangular solid is the product of the length, width, and height.

V = L W H

We could also write the formula for the volume of a rectangular solid in terms of the area of the base. The area of the base, B, is equal to length × width. B = L ⋅ W

We can substitute

B for L ⋅ W in the volume, formula to get another form of the volume formula.

The top line says V equals red L times red W times H. Below this is V equals red parentheses L times W times H. Below this is V equals red capital B times h.

We now have another version of the volume formula for rectangular solids. Let’s see how this works with the

4 × 2 × 3

Besides the solid is V equals Bh. Below this is V equals Base times height. Below Base is parentheses 4 times 2. The next line says V equals parentheses 4 times 2 times 3. Below that is V equals 8 times 3, then V equals 24 cubic units.

m∠BCD = m ∠ADC = 65°

4. AB = 15, DC = 25,

Answer:

250 gallons of water are being pumped out each hour

Step-by-step explanation:

It tells us that W is the amount of water in the pool at a time. It also tells us that at the start there is 9000 gallons in the pool. We also know t is the time in hours so 1 t = 1 hour.

W=9000-250t

We can substitute in what we know

The amount of water in the pool = 9000 gallons - 250 gallons times 1 hour

so that means if one hour passes 250 gallons are removed, and if 2 pass then 500 are removed showing that for every hour the pump is on 250 gallons of water are being sucked from the pool
