A) 100 m
B) 60 m C) 50 m D) 40 m E) 75 m

Answers

Answer 1
A is the correct answer that you’re looking for
Answer 2

Length of the train is 40 m. Therefore, option C is the correct answer.

Given that, a train traveling at a steady speed crossed a bridge which was 200 m long in 1 minute.

What is speed?

The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance traveled by a body in a given period of time. The SI unit of speed is m/s.

Now, 1 minute = 60 seconds

Here, speed of train = 200/60 = 3.33 m/s

Length of train = 3.33 × 12

= 39.96 m

≈ 40 m

Length of the train is 40 m. Therefore, option C is the correct answer.

Mumuni Bawumia, a farmer sells 500 litres of fresh milk a day with a standard deviation of 35 litres. Given that the daily sales of fresh milk is normally distributed, what is the probability that the sales in any single day is:
a. Greater than 506 litres

b. Between 498 litres and 506 litres.
​

Answers

Answer:

a:     0.43194

b:     0.09084

Step-by-step explanation:

First construct the z values for 498 and 506.

[tex]z=\frac{x-u}{s}[/tex]

[tex]z(498)=\frac{498-500}{35}[/tex]=-0.05714

z(506)=(506-500)/35=0.17143

Check the cumulative normal distribution tables to find

P(x<=-0.05714)=0.47722

P(x<=506)=0.52278

These probabilities imply that

P(x>506)=1-P(x<=506)=1-0.52278=0.43194

P(498<=x<=506)=P(x<=506)-P(x<=498)=0.09084

A triangle is 20 in tall and 5 in wide. If it is reduced to a width of 1 in then how tall will it be?​

Answers

Answer:

4 inches tall

Step-by-step explanation:

To find how tall it will be, use the same reduction scale that was used to reduce the width.

This scale is 5, since 5 divided by 5 is 1.

So, to find how tall it will be, divide 20 by 5:

20/5

= 4

So, it will be 4 inches tall

joel is designing a ramp for a bike trick. He draws this diagram. What is the value of x?

Answers

Answer:

x = -1

x = 5

Step-by-step explanation:

Use pythagorean theorem: a² + b² = c²

x² + (2x + 2)² = (2x + 3)²

Since these are quantities, you'll have to make them into quadratic equations.

(2x + 2)(2x + 2) = 4x² + 4x + 4x + 4

(2x + 3)(2x + 3) = 4x² + 6x + 6x + 9

x² + 4x² + 4x + 4x + 4 = 4x² + 6x + 6x + 9

Combine like terms

5x² + 8x + 4 = 4x² + 12x + 9

Move one side to set the equation equal to 0

x² - 4x - 5 = 0

Solve

x² - 5x + x - 5 = 0

x(x - 5) + 1(x - 5) = 0

(x + 1)(x - 5) = 0

x = -1, 5

We can check that these are correct by plugging them in for x and seeing if they are equal

For example

(-1)² + (2(-1) + 2)² = (2(-1) + 3)²

1 = 1
