Answer:

4 bags

Step-by-step explanation:

Since there were five in total, and each got 4/5 evenly, it's just basic adding while subtracting the amount from the other bags.

So to get 5/5, which is a full bag, you take portions out of the others to create a full one. Write out 4/5, five times, and then subtract the needed portions from a separate bag to combine a full one.

Answer:

-6.28576e+81

Step-by-step explanation:

Answer:

This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by  2  gives the next term.

Answer:

Domain is your x max and Min, Range is your y max and Min

Step-by-step explanation:

Domain would be -5 to 8 or (-5,8)

range would be -3 to 2 or (-3,2)

Answer:

Domain is every value on the x axis that the line in on. -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 is the domain or -5 to 8. The range is every Y value.

Step-by-step explanation:

Basically, Domain is the x values of the whole line and range are the y values for the whole line. Hope I helped <3

Answer:

exponential expression:

8ᵇ = 2

log8(2) = 0.333333333 or 1/3

Answer:

log8(2) = 1/3

Step-by-step explanation:

I don't know if they mean this by an exponential expression but:

set x = log8(2), then

8^x = 8^(log8(2))

By logarithmic properties:

8^x = 2.

notice that 8 = 2^3.

By exponential properties:

8^x = (2^3)^x = 2^(3x)

So 2^(3x) = 2 = 2^1.

Comparing exponents gives:

3x = 1 <=> x = 1/3.

So log8(2) = 1/3.

Step-by-step explanation:

If a boy student was picked, the probability that they passed is 0.25 * 0.4 = 0.1.

If a girl student was picked, the probability that they passed is 0.75 * 0.25 = 0.1875.

Total probability = (0.1 + 0.1875) * 100% = 28.75%.

Answer:

The opposite sides are "parallel and congruent". The opposite angles are congruent. The consecutive angles are supplementary. If anyone of the angles is a right angle, then all the other angles will be the right angle.

Answer:

A = $2,122.20

Step-by-step explanation:

A = P(1 + r/k)^kt

Where,

A = future amount

P = principal = $1,500

r = interest rate = 7%

k = number of periods compounded = 4

t = years = 5 years

A = P(1 + r/k)^kt

= 1,500 (1 + 0.07/4)^4*5

= 1,500 (1 + 0.0175)^20

= 1,500 (1.0175)^20

= 1,500 (1.4148)

= 2,122.20

A = $2,122.20

Step-by-step explanation

In an auditorium, there are 21 seats in the first row and 29 seats in the second row. The number of seats in a row continues to increase by 8 with each additional row. How would you find the 100th row?

We can take this as an arithmetic sequence, as the seats in next row is calculated by adding 8 to previous row

So here common difference will be 8

the first term is 21

the arithmetic sequence is given by:

Putting the values of a1 and d

for 100th row,

Putting n=100

3. The sequence 6, 18, 54, 162, … shows the number of pushups Kendall did each week, starting with her first week of exercising.

Give the rule you would use to find the 20th week.

Given sequence is:

6, 18, 54, 162, …

we can see that the common difference is not same so we will find the common ratio

The given sequence is a geometric sequence as are the same for consecutive terms

The geometric sequence is given by:

Hence,

2. Seats in 100th Row = 813

3. Rule is:

Keywords: Sequence, ratio

Answer:

see explanation

Step-by-step explanation:

The sequence is

22, 28, 34, ....

Since there is a common difference of 6 the sequence is arithmetic with n th term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

a₁ is the first term and d the common difference

Here a₁ = 22 and d = 6, then

[tex]a_{n}[/tex] = 22 + 6(n - 1) = 22 + 6n - 6 = 6n + 16

Equate to 100 and solve for n

6n + 16 = 100 ( subtract 16 from both sides )

6n = 84 ( divide both sides by 6 )

n = 14

Thus the 14 th row has 100 seats

Answer:

Question 2: √x

Question 5: B and D

Step-by-step explanation:

If you move a factor from the denominator to the numberator (or vice versa) its exponent must flip sign.

I.e., [tex]\frac{1}{x^{-1}}[/tex] will become [tex]\frac{x^1}{1}}[/tex] which is x

Multiplying the same number x you must add the exponents. (1/3)+(1/3)+(1/3) is 1, so D is also x¹.

Therefore B and D are equivalent.
