Arada [10]

Answer:

The mass of each passenger is 550 kg.

The mass of front decoration is 200 Kg.

Step-by-step explanation:

Given : A roller coaster train with 6 passenger cars and the front decoration has a mass of 3500 kg. when the train has the front decoration and only 4 passenger cars, it has a mass of 2400 kg.

To find : What is the mass of the decoration and of each passenger car?

Solution :

Let the mass of each passenger is x.

Let the mass of front decoration is y.

When the number of passenger = 6

Mass of 6 passengers and front decoration = 3500 kg.

The equation form is $6x+y=3500$ ..........[1]

When the number of passengers = 4

Mass of 4 passengers and front decoration = 2400 kg.

The equation form is $4x+y=2400$ ........[2]

Solving equation [1] and [2]

Subtract equation [2] from [1],

$6x+y-4x-y=3500-2400$

$2x=1100$

$x=550$

Put value in [1],

$6(550)+y=3500$

$3300+y=3500$

$y=200$

Therefore, The mass of each passenger is 550 kg.

The mass of front decoration is 200 Kg.

gina has a box of red blue and green markers. The ratio of the number of red markers to the number blue markers is 5:2. The rati

sweet [91]

This can be solve by cancel of units

Snice red/ bkue = 5/2

And bkue/ green = 3/ 5

So red/ green = (red/ bkue) x( blue/ green)

Red/ green = (5/ 2) x (3/ 5)

Red / green = 3 /2

So the ratio of red is to green is 3: 2

# 15. Q. Find the area of the trapezoid

harina [27]

Answer:
219.96 yd²

Explanation:
The area of the trapezoid can be calculated using the following rule:
Area of trapezoid = $\frac{b1 + b2}{2} * h$
where:
b1 is the length of the first base
b2 is the length of the second base
h is the height

Now, in the given we have:
b1 = 15.8 yd
b2 = 21.8 yd
h = 11.7 yd

Substitute with the givens in the above equation to get the area as follows:
area = $\frac{15.8 + 21.8}{2} * 11.7 = 219.96 yd^2$

Hope this helps :)

Solve 3x - 1/2 = 8 1/2 a. x=2 2/3 b. x= 2 1/3 c. x= 8 d. x= 3

Alenkinab [10]

We will first add 1/2 to both sides to get 3x = 9
We then divide both sides by 3 to get
x =3 (D)
