The sum of the speeds two trains is 717.6 miles per hour. If the speed of the first train is 6.4 mph faster than that of the second train, find the speeds
of each.
What is the speed of the first train?

Answers

Answer 1

Train 1 = x + 6.4

Train 2 = x

(x) + (x + 6.4) = 717.6

2x + 6.4 = 717.6

2x = 711.2

x = 355.6

Train 1 = 355.6 + 6.4 = 362 mph

Train 2 = 355.6 mph

Hope this helps!! :)

Is 13 ft the correct length?

Answers

Answer:

Your answer is incorrect 22 ft is correct

Step-by-step explanation:

We can check if 13ft is correct by using the volume formula and seeing if it equals the volume given

so volume is

width * length * height

if the length is 13

lets try it!

8  * 13 * 5

= 520 this is not correct the volume stated is 880

Let's try the next answer 22 ft

8 * 22 * 5

= 880

22 ft works that will be your answer

hope this helps!

h = height of the prism

The base is a regular hexagon. We are given the side length, 8.1 m, and the apothem, 7 m.

A = nsa/2,

where n = number of sides,

s = length of one side

a = apothem

volume = Ah

volume = nsa/2 * h

volume = 6(8.1 m)(7 m)/2 * 21 m

Aubrey is studying for her math test. She knows she will need to round decimals to the tenths place on her test, but she forgets how to do it. Using the number 125.671 as an example, remind Aubrey the steps to rounding decimals to the nearest tenth.

Answers

Answer:

125.7

Step-by-step explanation:

To round 125.671 to the nearest tenth consider the hundredths’ value of 125.671, which is 7 and equal or more than 5. Therefore, the tenths value of 125.671 increases by 1 to 7.

125.671 rounded to the nearest tenth = 125.7

The following table contains starting numbers close to 125.671 rounded to the nearest 10th.

Answer:

If a number has a decimal point, then the first digit to the right of the decimal point indicates the number of tenths.

Step-by-step explanation:

in the question, the number 125.671 the decimal is after 5 and before 6. so, the tenth place is 6 and it is greater than 5. we can round it to 125.7

Here's how to make ramen though.

INGREDIENTS:

2 large eggs

1 tablespoon olive oil

4 cloves garlic, minced

1 tablespoon freshly grated ginger

4 cups reduced sodium chicken broth

4 ounces shiitake mushrooms

1 tablespoon reduced sodium soy sauce

3 (5.6-ounce) packages refrigerated Yaki-Soba, seasoning sauce packets discarded*

3 cups baby spinach

8 slices Narutomaki, optional*

1 carrot, grated

2 tablespoons chopped chives

DIRECTIONS:

Place eggs in a large saucepan and cover with cold water by 1 inch. Bring to a boil and cook for 1 minute. Cover eggs with a tight-fitting lid and remove from heat; set aside for 8-10 minutes. Drain well and let cool before peeling and halving.

Heat olive oil in a large stockpot or Dutch oven over medium heat. Add garlic and ginger, and cook, stirring frequently, until fragrant, about 1-2 minutes.

Whisk in chicken broth, mushrooms, soy sauce and 3 cups water.

Bring to a boil; reduce heat and simmer until mushrooms have softened, about 10 minutes. Stir in Yaki-Soba until loosened and cooked through, about 2-3 minutes.

Stir in spinach, Narutomaki, carrot and chives until the spinach begins to wilt, about 2 minutes.

Serve immediately, garnished with eggs.

the parabola has y intercept of -2 and turning point at (2,2)
Give the equation of this parabola?​

Answers

Answer:

y=-(x-2)^2+2

Step-by-step explanation:

The equation for a parabola is y= a(x-h)^2+k.

The turning point is (2,2) which represents the (h,k) value

y=a(x-2)^2+2

Now solve for a. by using the y-int is (0,-2), and plugging it into the equation.

-2=a(0-2)^2+2

a= -1

Plug your a value into the equation.

y=-(x-2)^2+2
