Answer:

  a)  21, 34.5, 54.75, 85.125

Step-by-step explanation:

All of the answer choices differ in the first term, so that is the only one you need to figure here. However, we will do them all, so you can see it done.

We note that x > 0 for all of the values of x that we need to use. That means the recursive relation is the one we're using for computation.

f(1) = 3/2·f(0) +3 = (3/2)(12) + 3 = 18 +3 = 21 . . . . . . matches choice (a)

f(2) = 3/2·f(1) +3 = (3/2)(21) +3 = 63/2 +3 = 69/2 = 34.5

f(3) = 3/2·f(2) +3 = (3/2)(34.5) +3 = 51.75 +3 = 54.75

f(4) = 3/2·f(3) +3 = (3/2)(54.75) +3 = 82.125 +3 = 85.125

When you're computing for sequential input values, each depends on the previous value you computed.

ANSWER-

Answer:

1. B
2. A
3. D
4. C

Answer:

750

Step-by-step explanation:

Given:

discount of 25%

Hasan's equation:  d - 0.25d

Bella's equation: 0.75d

d represents the original price.

0.25d represents the discount.

0.75d represents the discounted price.

Example: 1,000 is the price. d = 1,000

0.25d = 0.25(1000) = 250 this is the discount

0.75d = 0.75(1000) = 750 this is the discounted price

Hassan: d - 0.25d =  1000 - 250 = 750

Bella: 0.75d = 0.75(1000) = 750

Answer:

3.46grams

Step-by-step explanation:

Answer:

  the correct choice is marked

Step-by-step explanation:

The tip is 20% of the bill:

  20% × $124.00 = $24.80

When that is added to the bill, the total is ...

  $124.00 +24.80 = $148.80

Answer:

A.

Step-by-step explanation:

You need to find 20% of the order to find the tip then add that to the original bill.

So, you need to solve 124x0.20 to get 24.80. That's the tip.

Next, add 124+24.80=148.80. There is your answer.

Hope you get an A! <3

Answer:

.53

Step-by-step explanation:

divide 8 by 15 and you get 0.53 explanation As a decimal 8/15 is 0.533 (3 repeating) or about 0.53. To convert 8/15 into a decimal value we simply divide 8 by 15. Since 15 cannot be divided into 8 we add a decimal and a zero then divide 15 into 8, giving us 5 with 5 remaining. Adding another zero allows us to divide 15 into 50 3-times with 5 remaining.

Answer:

D

Step-by-step explanation:

1. Add the costs together 10.98+13.95+22.56=47.49

2. To get an average, divide by the amount of numbers you added together. We added 3 numbers together (10.98+13.95+22.56) so we divide by 3.

47.49/3=15.83

The option closest to our number is D so we round up.

$15.83->$20

Have a good day.

Answer:

C

Step-by-step explanation:

add up breakfast, lunch, and dinner averages. equals 47.49 which is close to $50 for the day

The number of comedy DVDs will be equal to 604.

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that the total number of DVDs are 1830 and the percentage of comedy DVDs is 33%.

The number of comedy DVDs will be calculated as,

N = ( 1830 x 33%)

N = (1830 x 33 ) / 100

N = 604

Therefore, the number of comedy DVDs will be equal to 604.

Answer:

She pays $2.13 per each bag

Step-by-step explanation:

we know this because 10.65/5 (5 being the amount of bags she bought) and 10.65 being how much money she spent.) Divide the 2 (10.65 / 5) you get $2.13

It would be 13.3 years till the mass of the sample reached 24 grams.

'A quantity is subject to exponentially decay if it decreases at a rate proportional to its current value.'

According to the given problem,

Let x be the number of years spent,

Initial mass = 40 grams

Final mass = 24 grams

Half-life = 18 years

⇒ 24 = 40 × [tex]0.5^{\frac{x}{18} }[/tex]

⇒ 24/40 = 0.5^[tex]\frac{x}{18}[/tex]

⇒ 3/5 = 0.5^[tex]\frac{x}{18}[/tex]

Taking ln on both sides,

⇒ ln (3/5) = [tex]\frac{x}{18}[/tex] ln 0.5

⇒ ln (3/5) / ln (0.5) = x/18

⇒ x = ( 18 × ln (3/5) ) / ln (0.5)

⇒ x = 13.3 years

Hence, we can conclude that the sample need s 13.3 years to decrease its mass from 40 grams to 24 grams.

The cost per friend is $6.84.

The first step is to determine the total cost of the vegetables the two friends bought.

Total cost of the vegetables = ( 1 x $2.82) + 4.19 X 2 + (1.24 x 2) = $13.60

In order to determine the cost per friend, divide the total cost of the vegetables by the number of friends that purchased the items.

$13.6 / 2 = $6.84

{one more} {than one third the number of dolls than Sally has}

       ↥                                                 ↥                          

       1                                                s/3

This means that Anne has s/3 + 1 dolls, which is 9 dolls.

Hence, the equation that represents the word problem is S/3 + 1 = A.

Step-by-step explanation:

1. We have to divide 4200 by a number which is a multiple of 10.

Let us assume that the number is 20, which is a multiple of 10.

Now, after division the quotient will be .

2. We have to check whether the quotient is multiple of 10 or not.

Here, the quotient is 210 which is a multiple of 10.

Hence, the required number which is a multiple of 10 is 20.
