A classic children's toy consists of 13 different blocks that combine to form a rectangle showing a man's face. Each block has f

our sides with alternatives for that part of the face; for example, the block for the right eye might have a closed eye on one side, a partially open eye on another, and so on. A child can turn any block and so change that part of the face, and in this way many different faces can be formed.
How many different faces can be formed by the children's toy?

Answer: 67,108,863 combinations.

Step-by-step explanation:

We have 13 blocks.

Each block has 4 differet options.

The total number of combinations is equal to the product of the options for each variable (the variables are the 13 blocks) so we have that the number of combinations is:

C = 4*4*4*4*4*4*4*4*4*4*4*4*4 = 4^13 = 67,108,863

Nataly_w [17]

Hey there! Welcome to Brainly!

Let's see how many marbles we have in total.

12+11+17+5=45

We want to find the probability of selecting a marble that is not blue. Let's see how many marbles aren't blue.

12+11+5=28

We have this probability out of 48.

28/48

We simplify, giving us 7/12 or about 58.33%.

I hope this helps!

Liam earns 7.50 an hour his benefits package is equal to 25 percent of his hourly wages when you include that valid if his benef
IgorC [24]

Answer:

Liam earns $9.375 per hour

Step-by-step explanation:

<em>The given information is</em>

  • Lima earns $7.50 per hour
  • His benefits package is 25% of his hourly wages

We need to find his hourly wages when his benefits package is included

Assume that he earns 100% per hour

∵ He earns 100% per hour

∵ His benefits package is 25% of his hourly wages

→ Add 25% to 100% to find his total hourly wages

∴ He will earn = 100% + 25% = 125% of his hourly wage

→ Find the value of 125% of his hourly earn

∵ 125% of 7.50 = \frac{125}{100} × 7.50 = 9.375

∴ His hourly earns = $9.375

Liam earns $9.375 per hour

The table below shows how much Joe earns, y, after working x hours.
allochka39001 [22]
Both slopes have the same value which is 7.5.

To compute for the slope we will use this formula:
   m = y^2 - y^1 over x^2 - x^1

For the first slope, the points are<span> (4, 30) and (12, 90). Substitute and simplify.
   m = (90 - 30) over (12 - 4)
   m = 7.5

For the second slope, the points are </span><span>(4, 30) and (10, 75). Same with the above computation.
   m = (75 - 30) over (10 - 4)
   m = 7.5

Since the relationship is linear, the slope does not change. </span>
