Answer 1

If both trains just left the station on parallel tracks, then both leave the station together again;

We will solving for the LCM (Least Common
Multiple),

The LCM of 12 and 9
12=2×3×4x6 × 12
9=3x1 x 9

The LCM of 12 and 9 is 36

Hence, Both trains will leave the station together again in B. 36 minutes.

Answer 2

Both trains will leave the station together again in B. 36 minutes.

What is the fundamental principle of multiplication?
Multiplication is the mathematical operation that is used to determine the product of 2 numbers or more numbers.

We have been given that “A” train leaves a subway station every 12 minutes. An “E” train leaves every 9 minutes.

If both trains just left the station on parallel tracks, then both leave the station together again;

We will be solving the LCM (least common multiple)
The LCM of 12 and 9
12=2x3x4x6x12
9=3x1x9

The LCM of 12 and 9 is 36

Hence, both trains will leave the station together again in B. 36 minutes.

Answer: 1/2, 0.51, 11/20

Step-by-step explanation:

Use 100 as a common denominator so you can compare all the numbers in like terms:

1/2 = 50/100

0.51 = 51/100

11/20 = 55/100

Answer:

[tex]\frac{1}{2} 0.51, \frac{11}{20}[/tex]

Step-by-step explanation:

First, you want to change the decimal into a fraction. 0.51= [tex]\frac{51}{100}[/tex]

Then, find the common denominator. In my example, I used 100. Find the equivalent fraction for the fractions with 100 as their denominator

[tex]\frac{11}{20} = \frac{55}{100} \\\\\ \frac{1}{2} = \frac{50}{100}[/tex]

Next, line them up in order of their numerators

[tex]\frac{50}{100} \frac{51}{100} \frac{55}{100}[/tex]

Finally, match the new fraction with their reduced fraction or decimal:

[tex]\frac{1}{2} = \frac{50}{100} \\\\0.51 = \frac{51}{100} \\\\\frac{11}{20} = \frac{55}{100}[/tex]

a recipe for vanilla cake calls for 2 cups of sugar for every 4 eggs. what is the ratio of sugar to eggs?

Answers

The ratio (or raicios) are 2:4, 4:8, 8,16, so on and so on.

__________________________________________

The question states, vanilla cake calls for 2 cups of sugar for every 4 eggs. So basically you would add 2 every time you count to 4. Ex: 4 x 3 = 2 x 3,

4 x 6 = 2 x 6. Whatever happens to one side, has to happen to the other.

2:4 would be the ration of sugar to eggs

An employee works 38 hours a week for 50 weeks per year. If he earns 39,095 a year towards his family budget, what is his hourly wage?

Answers

Answer:

$20.57

Step-by-step explanation:

First you have to find how many hours he/she works per week (38) and how many weeks he/she works a year (50) and how much he/she makes a year (39,095)

Now in order to find this we have two ways I will use the simpler way so it makes it easier to write and tell to you're teacher :)

First you multiply 50 and 38

50 × 38 = 1900

Since you know how much he/she makes a year you just divide.

39,095 ÷ 1900 = 20.57

So that makes your answer 20.57, Hope this helps and if it did and if I deserve it pls give brainlyest thank you :)

a) The step where Mardie first made an error is given as follows: Step 1, as the negative sign means that the sign of each term inside the parenthesis should be changed.

b) The correct expression is given as follows: -8.6b + 28.

How to simplify the expression?

The expression in the context of this problem is defined as follows:

(-3.78b + 12) - (4.82b - 16).

The negative sign before the parenthesis means that the sign of each term inside the parenthesis is changed, hence:

-3.78b + 12 - 4.82b + 16.

This is the step where Maddie made the first error.

Then, to simplify the expression, we combine the like terms, as follows:

b(-3.78 - 4.82) + 12 + 16 = -8.6b + 28.
