A train has 6 identical passenger cars that are each 18 m long.
Gnesinka [82]

Answer:

59m

Step-by-step explanation:

No of passenger cars in the train = 6

length of each passenger cars = 18m

total length of 6 passenger cars = 18 * 6 = 108 m

length of caboose = 10m

total length of train when caboose is included = 108 m + 10 m = 118m

_____________________________________________

Let the length of truck be X m

given that length of train is twice of length of truck = 2*X

but length of train as found above is 118 m

this implies

2X = 118

X = 118/2 = 59m

Therefore length of truck is 59m

There are 3 consecutive integers that add up to 9 which integers are they?
matrenka [14]

Answer:

The integers are 2,3,4

Step-by-step explanation:

Let one integer be = x

Since, the integers are consecutive, so they will increase by one.

So, 2nd integer will be =x+1

3rd integer will be =x+1+1=x+2

It is given that the 3 integers add up to 9.

So, we have the sum equation as:

x+x+1+x+2=9

Solving for x

Combining like terms.

3x+3=9

Subtracting both sides by 3.

3x+3-3=9-3

3x=6

Dividing both sides by 3.

\frac{3x}{3}=\frac{6}{3}

x=2

∴ 1st integer = 2

2nd integer = 2+1 = 3

3rd integer = 2+2 = 4

the length of a chord of a circle is 24 cm long and is 5 cm away from the center of the circle what is the radius of the circle​
iogann1982 [59]

Answer:A chord with length 24 cm at 5 cm from the center gives a radius of 13 cm, using a half-length of 12 cm and the distance of 5 cm in Pythagoras’s theorem to find the radius.

Using the same radius and Pythagoras's theorem again, a chord 10 cm from the circle with radius 13 cm has a half-length of sqrt(69), or a full length of double that, so 2*sqrt(69).
