Answer:

3.56X10^-6

Step-by-step explanation:

In converting numbers to scientific notation, simply move the decimal point of the number until the numerical coefficient is greater than 1 but less than 10. Be sure to take note of the following:

1. The numerical coefficient.

2. Number of times we move the decimal point. It will be the exponent with the base of 10.

3. The direction we take in moving the decimal point. If the direction is to the right, take the negative sign for the exponent. If the direction is to the left, take the positive sign for the exponent.

Here, we move the decimal point of 0.00000356 to the right 6 times. So, we have now 3.56X10^-6.

Answer:

Smaller angle = 66 degrees

Larger angle = 114 degrees

Step-by-step explanation:

Smaller angle: x

Larger angle: 2x - 18

x + 2x - 18 = 180 degrees

3x = 180 + 18

x = 198/3

x = 66

180 - 66 = 114

Final answer:

The measure of the smaller angle is 66 degrees and the measure of the larger angle is 114 degrees.

Explanation:

Let's represent the measure of the smaller angle as x. According to the problem, the larger angle is 18 less than twice the measure of the smaller angle, so we can represent the larger angle as 2x - 18.

Since the two angles are supplementary, their sum is 180 degrees:

x + (2x - 18) = 180

Solving this equation, we get:

3x - 18 = 180

3x = 198

x = 66

Therefore, the measure of the smaller angle is 66 degrees and the measure of the larger angle is 2(66) - 18 = 114 degrees.

Final answer:

The system of equations can be solved using the method of elimination. The solution is x = -6 and y = 8.

Explanation:

To solve this system of equations, we can use the method of elimination. First, we'll multiply the first equation by 10 and the second equation by 2 to make the coefficients of x the same. This gives us:

1. 
   
2.  
3. 90x + 20y = -380
4. 
   
5.  
6. 18x + 20y = 52

Now, we can subtract the second equation from the first to eliminate y:

72x = -432

Dividing both sides by 72, we find x = -6.

Substituting this value of x into one of the original equations, we can solve for y:

9(-6) + 2y = -38

Simplifying, we get -54 + 2y = -38

Adding 54 to both sides, we have 2y = 16

Dividing both sides by 2, we find y = 8.

Answer:

The exact probability = 0.0431

Step-by-step explanation:

Given: A bag contain - Caramels= 12, mints= 12, bars of dark chocolates=  14

Marilyn picks three items from the bag without replacement.

Total number of items 12+12+14=36

Now, probability = favorable outcome / total no. of outcomes

Probability of picking a mint =

After picking a mint there are :

caramels=10, mints=11, bars of chocolate=14

Total items in the bag=35

Probability of picking another mint =  

now, caramels=10, mints=10, bars of chocolate=14

Total items in the bag=34

Probability of picking a bar of dark chocolate =  

The exact probability of picking the items:

Therefore, the exact probability = 0.0431
