the difference is the value of the new exponent with the same base.

Answer:

6 containers

6 ounces of fruit snack will be left over

Step-by-step explanation:

1 pound = 16 ounces

⇒ ¹/₂ pound = 8 ounces

Total weight = weight of dried apples + weight of dried cranberries

                     = 36 + 18

                     = 54 ounces

Containers needed = total weight ÷ weight of snacks in one container

                                 = 54 ÷ 8

                                 = 6.75

Therefore, he will fill 6 containers

Snack left over = total weight - (number of containers × weight of snacks one container will hold)

                          = 54 - (6 × 8)

                          = 54 - 48

                          = 6 ounces

Answer:

6.1291 < 8.3 < 8.308 < 8.38

Step-by-step explanation:

Start by looking at the whole numbers.

6 < 8

Since the only whole numbers are 6 and 8, we can rule out that the smallest number, or with the least value, is 6.

Next, look at the tens place.

Since they are all 8.3--, we cannot find the next one until we look at the hundredths place.

Next, look at the hundredths place.

Keep in mind that 8.3 is the same as 8.300

There is 8.30 < 8.38 and 8.308 <8.380

Now we know the lowest value and the highest value! (6.1291 and 8.38)

Between the last two, let's figure out where they place

Look at the thousandths place.

8.300 < 8.308

Hence, the answer provided above!

6.1291  < 8.3 < 8.308 < 8.38

Hope this helps! :)

Answer:3,221.6

Step-by-step explanation: if you divide 54,000 by 12, you get 4,500 which is the untaxted payment per month, then you must divide 15,340.80 by 12, which is 1,278.4, then you subtract that from 4,500 which ends up being 3,221.6

Answer:

x = 44.5 due to the Triangle Angle Sum Theorem

Step-by-step explanation:

This is the Triangular Angle Sum Theorem.

This rule states that every angle inside the triangle has to equal 180.

This is a solve for x situation

2x + x + x + 2 = 180

Add all the x's first

3x + x + 2 = 180

4x + 2 = 180

Now subtract 2 both sides

4x = 180 -2

4x = 178

Divide 178 by 4

x = 44.5

You could verify by plugging 44.5 into the x's

2(44.5) + 44.5 + 44.5 + 2 = 180

89 + 44.5 + 46.5 = 180

Answer:

x = 44.5

Step-by-step explanation:

2x + x + (x+2) = 180

4x + 2 = 180

4x = 178

x = 44.5

Answer:

c.  0.219

Step-by-step explanation:

If the coin is fair, then the probability of flipping a head is 1/2 = 0.5

Therefore, we can model this as a binomial distribution:

X ~ B(n, p) where n is the number of events and p is the probability of success

Given:

X ~ B(8, 0.5)

Using a calculator:

P(X = 5) = 0.21875 = 0.219 (3 dp)

Using the formula:

[tex]\sf P(X=x)=\dfrac{n!}{(n-x)!x!}p^x(1-p)^{n-x}[/tex]

(where n is the number of events, x is the number of desired successes and p is the probability of success)

[tex]\sf \implies P(X=5)=\dfrac{8!}{(8-5)!5!}0.5^5(1-0.5)^{8-5}[/tex]

[tex]\sf \implies P(X=5)=\dfrac{8!}{3!5!}0.5^50.5^3[/tex]

[tex]\sf \implies P(X=5)=56 \cdot 0.5^8[/tex]

[tex]\sf \implies P(X=5)=56 \cdot \dfrac{1}{256}[/tex]

[tex]\sf \implies P(X=5)=\dfrac{7}{32}[/tex]

[tex]\sf \implies P(X=5)=0.21875[/tex]

Answer:

$2,400

Step-by-step explanation:

First we need to find whatever that 5% is.

[tex]\frac{5}{100} \times \frac{2000}{1}[/tex]

Which gives us $100.

Now, we multiply the $100 by 4.

Which is $400.

Now, we add that to the $2,000.

Which gives us $2,400.

Answer:

  4 mph

Step-by-step explanation:

Travel time is proportional to distance and inversely proportional to speed. If c represents the speed of the current in miles per hour, an equation for the total trip time is ...

  825/(29 -c) +825/(29 +c) = 58 . . . . . . hours travel time

  825(29 +c) +825(29 -c) = 58(29 -c)(29 +c)

  58c² -928 = 0 . . . . . . . rearrange to standard form

  58(c -4)(c +4) = 0 . . . . factor

Values of c that satisfy this equation are 4 and -4. For the purpose here, we'll choose the positive solution.

The speed of the current is 4 miles per hour.

Step-by-step explanation:

16+17+18=51

I knew the highest number had to be lower than 20. So I did 17+18+19. That didn't work but noticed it was close to 51. Tried 16+17+18 and it equals 51 :)

This is because there's one space labeled "2" out of 38 spaces total.

This fraction is approximately equal to 1/38 = 0.0263 meaning there's roughly a 2.63% chance of landing on this space.

The probability is 0.0263 that the ball will land on 2 in a random spin of the wheel.

The probability is defined as the possibility of an event is equal to the ratio of the number of outcomes and the total number of outcomes.

Assuming an unbiased wheel.

The probability of an event = number of favourable outcomes/ number of total outcomes.

The total number of outcomes is 38

The number of favourable outcomes is one because there's one space labeled "2" out of 38 spaces total.

The probability of an event = 1/38 = 0.0263

Hence, the probability is 0.0263 that the ball will land on 2 in a random spin of the wheel.
