Answer:

4 hours and 30 minutes.

Step-by-step explanation:

660 miles = 1 hour
1320 miles = 2 hours
1980 miles = 3 hours
2640 miles = 4 hours

There are only 330 miles left and that is half of 660mph so therefore it would only take half an hour for these last 330 miles.

So we know that it will be taking 4 hours, you would then add the 30 minutes which gives you 4 hours and 30 minutes.

Hope this helps!

Answer:

x = 4.5

Step-by-step explanation:

8x + 12x + 90 = 180   {Sum of all angles of a triangle is 180}

20x + 90= 180

20x        = 180 - 90

       20x = 90

             x = 90/20

             x = 4.5

Answer:

  f^-1(x) = x +6

Step-by-step explanation:

To find the inverse of the function

  y = f(x)

solve the equation

  x = f(y)

for y.

Here, you want ...

  x = f(y)

  x = (y -6)

  x +6 = y . . . . . . add 6 to both sides

  [tex]\boxed{f^{-1}(x)=x+6}\\[/tex]

Answer:

35%

Step-by-step explanation:

The price it cost the site to buy the grills was $580 but they were selling them for $783. So for each grill, they get a profit of $203. (783-580=203).

35% of $580 is 203 which adds up to $783

So therefore the markup rate is 35% I hope this helps!

Answer:

A: -6

Step-by-step explanation:

Flip around the question

what is 12 - 18

If you count the numbers in between 12 and 18

You get 6

So now just make the answer negative

your answer is A.-6, i think its helpful

Answer:

6

Step-by-step explanation:

Here it's given that ,

[tex]\sf\red{\longrightarrow} A=\sqrt{s(s-a)(s-b)(s-c)}[/tex]

Also ,

[tex]\sf\red{\longrightarrow} s =\dfrac{a+b+c}{2}[/tex]

And we need to find out the value of A , when

So , on substituting the respective values to find s we have ,

[tex]\sf\red{\longrightarrow} s =\dfrac{3+4+5}{2}=\dfrac{12}{2}=\bf{6}[/tex]

Now let's find out A as ,

[tex]\sf\red{\longrightarrow} A = \sqrt{6(6-3)(6-4)(6-5)} \\[/tex]

[tex]\sf\red{\longrightarrow}A =\sqrt{6 * 3 * 2 * 1}\\[/tex]

[tex]\sf\red{\longrightarrow} A = \sqrt{3^2 * 2^2 *1^2}\\[/tex]

[tex]\sf\red{\longrightarrow}A = 3*2\\[/tex]

[tex]\sf\red{\longrightarrow}\boxed{\qquad \blue{\bf A = 6 \qquad}}[/tex]

Answer:

10.08

Step-by-step explanation:

In [tex]\triangle ABC,\: m\angle ACB =90\degree [/tex]

[tex]\implies \triangle ABC [/tex] is a right triangle, in which side AB is hypotenuse and sides AC and BC are mutually perpendicular.

By using Pythagoras theorem:

[tex]AC^2 = AB^2 - BC^2 \\ \\ = {(11)}^{2} - {(4.4)}^{2} \\ \\ = 121 - 19.36 \\ \\ = 101.64 \\ \\ \implies \: AC= \sqrt{101.64} \\ \\ \huge\implies \: \red{AC=10.08}[/tex]

Difference:

50-25=25kg

250-60=190gm

Answer:

A) not similar

Step-by-step explanation:

for the triangles to be similar the side lengths must be proportional.

For example:

99/35 should be equal to 121/44 but when we do cross multiplying we see they are not equal therefore the the triangles are not similar.

Answer:

14%

Step-by-step explanation:

50 - 43= 7,

Step-by-step explanation:

3(3x−1)=6x−3

9x-3=6x-3

   +3     +3

9x=6x

-6x  -6x

3x=0

/3   /3

x=0

There are no solutions.

-hope it helps

Answer:

x=0

Step-by-step explanation:

[tex]3(3x-1)=6x-3[/tex]

Use the distributive property to multiply 3 by 3x-1.

[tex]9x-3=6x-3[/tex]

Subtract 6x from both sides.

[tex]9x-3-6x=-3[/tex]

Combine 9x and -6x to get 3x.

[tex]3x-3=-3[/tex]

Add 3 to both sides.

[tex]3x=-3+3[/tex]

Add −3 and 3 to get 0.

[tex]3x=0[/tex]

Product of two numbers is equal to 0 if at least one of them is 0. Since 3 is not equal to 0, x must be equal to 0.

[tex]x=0[/tex]

Answer:

  it has a lower mass/volume ratio

Step-by-step explanation:

Density is the ratio of mass to volume. An elevator will have the same volume, regardless of the number of people. The mass will increase with the number of people.

An elevator with 50 people in it will have a higher mass/volume ratio than an elevator with 3 people in it. Hence the latter is less dense.

Additional comment

50 persons would require an industrial elevator of perhaps 10,000 pound load capacity. There might be safety issues with carrying that many people.

Answer:

14.42

Step-by-step explanation:

First, find the length of the leg of the bigger triangle (not the overall big triangle) using the Pythagorean Theorem. The overall length is 24, but we don't know the leg of the bigger triangle or the little triangle, so that is why we are going to find the length of the bigger triangle's leg. b = 12 and c = 20.

[tex]a^{2} + b^{2} =c^{2} \\a^{2} +12^{2} =20^{2} \\a^{2} +144=400\\a^{2} +144-144=400-144\\a^{2} =256\\\sqrt{a^{2}} =\sqrt{256}\\a = 16[/tex]

Next, find the leg of the little triangle by subtraction

24 - 16 = 8

Finally, you can find the hypotenuse of the little triangle by using the Pythagorean Theorem. a = 12 and b = 8

[tex]a^{2} + b^{2} =c^{2} \\12^{2} +8^{2} =2c^{2} \\64 +144=c^{2}\\208 = c^{2} \\\sqrt{208}=\sqrt{c^{2}} \\ c = 14.42[/tex]
