Answer:

It will take the train 1.2375 minutes to pass the tunnel

Step-by-step explanation:

Mathematically, we know that ;

time = distance/ speed

The distance here is the length of the train which is 132 m ; we can convert this to km by dividing by 1000

We have this as 132/1000 = 0.132 km

So, we have the time as;

0.132 km/6.4 km/hr = 0.020625 hr

Mathematically, we know that 60 minutes make an hour;

so we have

0.020625 * 60 = 1.2375 minutes

Solve for x and y. Geometry
Otrada [13]

Answer:

x =106.5

y = 73.5

Step-by-step explanation:

Angle x is 1/2 arc SPQ

x = 1/2(98+115)

x = 1/2(213)

x =106.5

We know that x+y = 180  since this is an inscribed quadrilateral in a circle

x+y=180

106.5 +y =180

Subtract 106.5 from each side

106.5-106.5 +y =180-106.5

y = 73.5

Madison wants to make cookies for her little sisters .she is cutting a roll into pieces that are 1/2 inch if the roll is 13 inch
Serggg [28]
If you’re cutting it into half inch pieces, you’ll take the length of the roll and multiply it by 2, so 13•2=26

A field is a rectangle with a perimeter of 1220 feet. The length is 100 feet more than the width. Find the width and length of t
rosijanka [135]
To start, let x represent the width and x+100 represent the length. Since the perimeter of a figure is the sum of all the measurements of the side which can be represented by (x+100)+(x+100)+x+x and since you know your perimeter is 1220, you can set the expression equal to 1220. This would look like this:
(x+100)+(x+100)+x+x=1220

Once you have done that, combine any like terms (combine terms with the same variables and raised to the same power together) which would simplify to this:
4x+200=1220

Now that you have your like terms simplified, subtract 200 from both sides to get 4x=1020 and finally, to solve for x, or find the width, divide both sides by 4 to get x=255.

Now that you have your width, now you must find your length as the question asks to find the dimensions of the rectangular field. To find the length, add 100 to the width, 255 since according to the information given, the length is 100 more than the width. When you add 100 to 255, you should get that your length is 355. 

Now that you have your length and width, you can conclude that the dimensions of the field is 255 by 355 feet, which is your answer :)
