Two trains, train a and train , weigh a total of 466 tons. Train A is heavier than train b. The difference of there weights is 326 tons. What is the weight of each train

Answer: A = 396 tons

B = 70 tons

Step-by-step explanation:

From the question,

Weight of A + Weight of B = 466

Weight of A - Weight of B = 326

A + B = 466 ......... i

A - B = 326 ..........ii

Subtract equation ii from I

2B = 140

B = 140/2

B = 70 tons

A = 466 - 70

A = 396 tons

help me please! someone?

**Answer:**

*105 for 3 hours*

**Step-by-step explanation:**

First we have to find that how much he is charged for 1 hour.

140 : 4 = 35 per hour

Then we have to find how much he is charged for 3 hours by multiplying with 3.

3 x 35 = 105 per 3 hours

**Answer:**

£105

**Step-by-step explanation:**

let y represent the unknown amount

£150 = 4 hrs

y = 3 hrs

we then cross multiply

£150 x 3 hrs = y x 4 hrs

450= 4y

divide both sides by 4

450/4 = 4y/4

105 = y

You collect a random sample of size n from a population and calculate a 98% confidence interval. Which of the following strategies produces a new confidence interval with a decreased margin of error?

A: Use a 99% confidence level.

B: Use a 95% confidence level.

C: Decrease the sample size.

D: Use the same confidence level, but compute the interval n times. Approximately 2% of these intervals will be larger.

E: Nothing can guarantee that you will obtain a larger margin of error. You can only say that the chance of obtaining a larger interval is 0.02.

**Answer:**

**B: Use a 95% confidence level.
**

**Step-by-step explanation:**

In the case when the random sample size from a population is collected and it determined the 98% confidence interval so that decrease the margin of error is to use a 95% confidence interval as it is needed to have a less critical value

So according to the given options, the option B is correct

Explain when you should reverse the inequality symbol when solving an equality.

**Answer:**

To do this, subtract 6 from both sides. − 3_x_ + 6 − 6 > 12 − 6. −3_x_ > 6. Now divide both sides of the inequality by −3. Since you're dividing by a negative number, you need to flip the inequality sign.

How to find a side of a square when area is given?

**Answer:**

length =√area use this formula

The** side length** of square can be found by taking the square root of Area.

Square are **closed polygon**s which consist of four sides and four angles.

Each angle is 90 degree.

All the sides are of **equal **length.

So, by the definition of square, we know that the side lengths of square are **equal**.

The **formula **to calculate the area of the square is,

Area = a², where a is the **length **of one side of the square.

Let **Area **be given, let it be equal to A.

Then,

a² = A

Taking **square root **on both sides,

a = √A

Hence the side length is found by taking the square root of Area.

11) A=84.7m²

12) A=75.2km²

13) A=28.05ft²

14) A=48yd²

**Step-by-step Explanation:**

11) A = 1/2(bh)

A = 1/2(14×12.1)

A = 1/2(169.4)

**A = 84.7m²**

12) A = 1/2(bh)

A = 1/2(16×9.4)

A = 1/2(150.4)

**A = 75.2km²**

13) A = 1/2(bh)

A = 1/2(5.1×11)

A = 1/2(56.1)

**A= 28.05ft²**

-18+x=-x+12

This one ??

**Answer:**

X = 15

**Step-by-step explanation:**

Let's solve your equation step-by-step.

−18+x=−x+12

Step 1: Simplify both sides of the equation.

x−18=−x+12

Step 2: Add x to both sides.

x−18+x=−x+12+x

2x−18=12

Step 3: Add 18 to both sides.

2x−18+18=12+18

2x=30

Step 4: Divide both sides by 2.

2x/2 30/2 = 15

PLEASE HELP ASAP!! DUE TODAY

**Answer:**

**Step-by-step explanation:**

when 1/2 inch equals 4 feet the room is 2.25 inches, then

2 1/4 = 8/4 + 1/4 = 9/4

9/4 inches is the scale distance of the room

each 1/2 inch is 4 feet so divide 9/4 by 1/2 then multiply that by 4 to find the distance of the room

9/4 ÷ 1/2 = 9/4

9/4 * 2/1 = 18/4

18/4 = 9/2

9/2 * 4 feet = 9/2 * 4/1

9/2 * 4/1 = 36/2

36/2=18

the room is 18 feet across

then if the scale is 2/3 of an inch is 4 feet , then

2/3 * 9/4 = 18/12

18/12 = 3 inches is the scale size of Quinto's room
