During a normal day, there are 280 planes taking off from the airport, but the airport is a lot busier during Christmas holiday, about 300 planes take off every day from the airport. During the Christmas holidays, the airport opens 10 hours during each day, how many planes take off from this airport in each hour? ​

Answer:

This is a simple multiplication problem.

If 2 people, Amanda and her best friend divide evenly and each get $24.28, this means that the total is $24.28 x 2

$24.28 x 2

$48.56

I'm sorry if I misunderstood.

Good luck mate! :)

Answer:

11 hours

Step-by-step explanation:

To find how many hours it took, divide -33 by -3

-33/-3

= 11

So, it took 11 hours for the change to be -33°F

Answer:

[tex]2n + 4 = 3n - 6[/tex]

Step-by-step explanation:

In order to translate from words into equarion, we just have to know what means what.

Twice a number can be represented as [tex]2n[/tex], adding four to that is [tex]2n + 4[/tex].

3 times a number is [tex]3n[/tex], and 6 less than that is [tex]3n-6[/tex].

So these are equal to each other, we get [tex]2n + 4 = 3n - 6[/tex].

Hope this helped!

Answer:

x=13

Step-by-step explanation:

[tex]g(x)=-4\\[/tex]

Therefore, substituting the value in the equation

[tex]g(x)=\sqrt{x+3} -8\\=>-4=\sqrt{x+3}-8\\ =>-4+8=\sqrt{x+3} \\=>4=\sqrt{x+3}\\[/tex]

Squaring both sides,

[tex]=>4^{2}=\sqrt{(x+3)} ^{2}\\=>16=x+3 \\=> x=16-3\\\\=>x=13[/tex]

Answer:

Strips should be 1.5 ft wide.

Step-by-step explanation:

Given:

Width of 1st piece = 6 ft

Width of 2nd piece = 7.5 ft

To find:

To find the maximum width possible to make strips of equal size from both the pieces.

Solution:

This problem can be visualized as if we are given two numbers and we have to find the Highest common factor for both of them i.e. HCF of 6 and 7.5 will be our answer.

Let us try to factorize the given factors:

[tex]7.5 = 3 \times 2.5 = \underline {3 \times 0.5} \times 5[/tex]

[tex]6 = 3 \times 2 = \underline {3 \times 0.5 }\times 2[/tex]

The common factors are highlighted above as underlined.

Therefore, the answer is 3 [tex]\times[/tex] 0.5 = 1.5 ft

Strips should be 1.5 ft wide.

Please see the attached images for full solution.

For question 3, the equation could have also been 3x°= 90°. However, I used ∠ sum of △ since I didnt want to assume that ∠ABC is a right angle.

Likewise for Q4, the polygon looks like a trapezium which means that the 2 horizontal lines are parallel and one could conclude that (3x +3)° +(2x +2)°= 180° (int. ∠s). But since it wasn't clearly indicated that they are parallel, I used the sum of interior angles to find x instead.

Step-by-step explanation:The tangent of an angle is the trigonometric ratio between the adjacent side and the opposite side of a right triangle containing that angle. Example: In the triangle shown, tan(A)=68 or 34 and tan(B)=86 or 43 .

Given two sides

if leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root: a = √(c² - b²)

if leg b is unknown, then. b = √(c² - a²)

for hypotenuse c missing, the formula is. c = √(a² + b²)

Answer:

$1.02 million

Step-by-step explanation:

Given

[tex]Amount = \$1.22\ million[/tex]

[tex]\%\ increase = 20\%[/tex]

Required

Determine the amount in 2007

Let the amount in 2007 be represented with x.

The relationship between these parameters is:

[tex]1.22\ million = x + 20\%\ of\ x[/tex]

[tex]1220000 = x + 20\% * x[/tex]

[tex]1220000 = x + 0.20* x[/tex]

[tex]1220000 = x + 0.20x[/tex]

[tex]1220000 = 1.20x[/tex]

Divide both sides by 1.20

[tex]\frac{1220000}{1.20} = x[/tex]

[tex]1016666.67 = x[/tex]

[tex]x = 1016666.67[/tex]

Hence, they paid $1.02 million in 2007

Step-by-step explanation:

Answer:

[tex]f^{-1}[/tex](x) = [tex]\frac{x-1}{2}[/tex]

Step-by-step explanation:

let y = f(x) and rearrange making x the subject, that is

y = 2x + 1 ( subtract 1 from both sides )

y - 1 = 2x ( divide both sides by 2 )

[tex]\frac{y-1}{2}[/tex] = x

Change y back into terms of x

[tex]f^{-1}[/tex](x) = [tex]\frac{x-1}{2}[/tex]

Answer:

if y=4.then 6(r+4).

which is 6r+24.

and if it is equal to zero which is like this then it will be 6r+24=0.

which will be 6r=-24.

r= -24/6.

r= -4.

C(t)=3000(1.002417)^12t+960t

if T=1 year then the saving will be : 4048.17

Step-by-step explanation:

3000 deposit amount, 2.9 compound monthly interest .  save 80 dollars  per month at home .

A=p(1+r)^t

A=3000(1+0.029/12)^12t

A=3000(1.002417)^12t dollars

for the amount saved at home=80*12t=960t dollars

C(t)=3000(1.002417)^12t+960t

if T=1 year then the saving will be :

C(t)=3000(1.002417)^12t+960t

add the whole numbers

[tex]2+4=6[/tex]

combine the fractions

[tex]\frac{5}{7}+\frac{3}{5}[/tex]

LCM is 35 because 7 * 5 =35

[tex]\frac{5}{7}=\frac{5\cdot \:5}{7\cdot \:5}=\frac{25}{35}[/tex]

[tex]\frac{3}{5}=\frac{3\cdot \:7}{5\cdot \:7}=\frac{21}{35}[/tex]

[tex]\frac{25}{35}+\frac{21}{35}=\frac{25+21}{35}[/tex]

[tex]=\frac{46}{35}[/tex]

change the improper fraction into mixed number

[tex]6+1\frac{11}{35}[/tex]

[tex]=7\frac{11}{35}[/tex]

Answer:

He took 30 weeks to save $ 500

Step-by-step explanation:

Let 'x' be the number of weeks

Money deposited after each week = $ 15

Money deposited 'x' weeks = 15 * x = 15x

Opening balance in his account = $50

So, money that will be in his account after x weeks =  50 +15x

Total money in the bank = $500

50 + 15x = 500

       15 x = 500 - 50 { Subtract 50 from both sides}

        15x = 450   { Divide both sides by 15}

     15x/15 = 450/15

x =  30 weeks

Answer:

y=8.4

Step-by-step explanation:

inverse proportion means y=k/x

k is the constant

y=12, x=7

k=xy ⇒7*12=84

y=84/x

y=84/10

y=8.4

As y varies inversely with x the value of y is 42/5 when x is 10.

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

Given, y varies inversely with x.

∴ y = k/x.

12 = k/7.

k = 84.

Now, x = 10.

∴ y = 84/10.

y = 42/5.
