A train moves at a constant speed of 35 m/s. How long it will take for the train to move 407 m? Select one: O a. 12 s O b. 16 5 O c. 335 O d. 8.15​

Answers

Answer:

The closest answer is 12.

Step-by-step explanation:

Since 12 multiplied by 35 is 420, it is the closest answer. 16.5 seconds is too much. 335 seconds is WAY too much to reach 407 meters. 8.15 seconds is too little. It is at least half of how much you want it to move.

HELP!!!!!!! Correct answers only!!!! Will give brainliest!!!!!! One-third cup of black beans provides 20% of the potassium you need daily. You must get the remaining 1,360 milligrams from other sources. How many milligrams of potassium should you consume daily?

Answers

Answer:

1,700 MG

Step-by-step explanation:

1, 360 / 2 = 40% of the daily amount since 20% is taken from the beans.

1360 / 2 = 680

680 (40%) / 2 = 340, which is 20%.

Then, add 20% (340) to 1, 360, which gives the full percentage.

PLEASE HELP, BEST ANSWER GETS BRAINIEST Each letter of the word "RESPONSIBLE" is written on a separate slip of paper and placed in a hat. 1) What is the probability of choosing an E? 2) What is the probability of choose an "E" and then an "R" without replacing the letter? Write as a fraction

Answers

Answer:

1) 2/11

2) 2/121

Step-by-step explanation:

1. Because there are 2 E's, you have to chances out of your 11 changes, thus why the fraction 2/11 is the solution.

2. You know that 2/11 is the first fraction, so now find R. R has a 1/11 chance of getting chosen, so you multiply 2/11 and 1/11 to get 2/121.

Answer:

1) 2/11

2) 2/121

Solve x − 2y = 3 for x.

Answers

Answer:

[tex]x=2y+3[/tex]

Step-by-step explanation:

So we have the equation:

[tex]x-2y=3[/tex]

And we want to solve for x. In other words, we want to isolate the x-variable.

So, add 2y to both sides of the equation.

[tex](x-2y)+2y=(3)+2y[/tex]

On the left, the 2y cancel. Simplify the right:

[tex]x=2y+3[/tex]

And we're done!

Answer:

x = 3 + 2y

Step-by-step explanation:

This is the answer because:

1) First, you have to isolate x, in order to isolate x you have to bring x to the end of the equation.

2) Then, you have to add 2y to both sides of the equation.  

Another way you can think of this is:

1) If you add 3 + 2y you would figure out the answer because if you want to find x for a subtraction equation, you can add the answer to the equation with the number.

For example, x - 20 = 10, now to figure this equation out, you can either isolate the x, or you can add the answer in the equation with the remaining number in the equation.

Hope this helps!

If the area of triangle is 1200 sq m and its length is 60 m , find the breadth .

Answers

Answer:

20 m

Step-by-step explanation:

The area of a triangle is 120 sq m

The length is 60 m

We are required to find the breadth

Therefore to find the breadth of the traingle the formular below will be applied

Area= length × breadth

120= 60 × breadth

Breadth= 120/60

= 20 m

Hence the breadth of the traingle is 20 m

Answers

Answer: A

Step-by-step explanation:

When you write exponential form to radical form, the fraction tells us that kind of root it is. Since it is a cubed root, as indicated by the 3 in front of the radical, we know that the fraction will be [tex]\frac{1}{3}[/tex]. If it were to be [tex]\frac{1}{3}[/tex], the entire radical would be to the power of 1. Since the radical is to the power of x, our answer would be [tex]125^{\frac{1}{3}x }[/tex].

14=7(2x-4)
I have to solve this equation using two different methods and I don’t know how

Answers

Answer:

14=7(2x-4)

0r, 14/7 = 2x-4

or, 2= 2x-4

0r,2x= 6

or x=3

14=7(2x-4)

14=14x -28

14x=42

x=42/14=3

Method 1

Divide both sides by 7 first to get

14 = 7(2x-4)

14/7 = 7(2x-4)/7

2 = 2x-4

Then add 4 to both sides

2+4 = 2x-4+4

6 = 2x

2x = 6

Finally, divide both sides by 2

2x/2 = 6/2

x = 3

which is the final answer

------------------------------------------------------------------------------------------------

Method 2

Distribute the 7 through to each term in the parenthesis

14 = 7(2x-4)

14 = 7*2x + 7*(-4)

14 = 14x - 28

Then we follow similar steps as done earlier. Add 28 to both sides

14+28 = 14x-28+28

42 = 14x

14x = 42

Then divide both sides by 14 to fully isolate x

14x/14 = 42/14

x = 3

Either way we get the same result. As to which method you pick (if you could only choose one), its up to you based on whichever you find easier.

The basic idea with either method is that we follow PEMDAS in reverse to undo everything happening to x. This way we fully isolate it.

----------------

Checking the answer:

Plug x = 3 into the original equation. Simplify to get

14 = 7(2x-4)

14 = 7(2*3-4)

14 = 7(6-4)

14 = 7*2

14 = 14

This confirms the answer. As you can see, if we know the value of x, we use PEMDAS to simplify both sides. But if we don't know x, and want to find it, then we follow PEMDAS in reverse.

The attached photo is the distance formula and I will try to explain how to do the first problem the best I can.
First, your points will be (-5,0) and (-4,5). Those are (x,y).
You plug -4 into the first x place and -5 into the second x place in the formula. You plug 5 into the first y place and the 0 into the second y place.
After doing the math within the radical you should end up with either 1^2 + 5^2 or 1 + 25.
I would put it into a calculator and you should end up with 5.1 as your answer (rounded)

What is the interior angle bisector theorem?

The interior angle bisector theorem states that in a triangle the angle bisector of an angle divides the opposite side to the angle in the ratio of the remaining two sides.

In ΔABC m∠A = 28° and the ratio is taken for the sides which is opposite to the given angle BC and the side which not base AB.

Given the ratio AB/BC.

∴ In ΔBCD in which m∠B is also 28° we have to take the same sides opposite side is DC and the side which is not the base BC.

So, in the triangles ABC and ABD The ratio which has the same value as AB/BC is BC/DC.

While sitting in class you overheard one of your classmates say, "This equation has infinite solutions, because when I put it in Desmos it gave me parallel lines so I know it makes a conditional equation." Realizing that the student is incorrect, what would you say to help your classmate get their facts straight?

Answers

Answer:

See below

Step-by-step explanation:

The systems of linear equations represent two lines.

There are 3 possible outcomes with two lines on the plane.

1. Lines intersect

In this case there is one solution, which is the point of intersection.

2. Lines are parallel

In this case the lines never intersect, so there is no solution

2. Lines are same

In this case the lines overlap, so there are infinitely many solutions.
