The expression p + 0.08p represents the total cost of an item with an initial price of p, plus an 8% sales tax. What is the total cost of an item with an initial price of $90?

Answers

Answer 1

Answer:

$97.2

Step-by-step explanation:=Given

The expression p + 0.08p

where P= the initial price

let y be the total cost, so that

y=p + 0.08p

for p=$90

y=90+0.08*90

y=90+7.2

y=$97.2

Hence the total cost for a $90 price is $97.2

Answers

Answer:

b) true for one value

Explanation:

If you solve for x, there is only one value of x

Answer:

(b)

Step-by-step explanation:

9(x - 2) = 7x + 5 ← distribute left side

9x - 18 = 7x + 5 ( subtract 7x from both sides )

2x - 18 = 5 ( add 18 to both sides )

2x = 23 ( divide both sides by 2 )

x = [tex]\frac{23}{2}[/tex]

Answers

Answer: Jerry walked 2 7/20 miles to get to the park

Step-by-step explanation:

1/2 of 3 1/2

1/2 of 7/2 = 7/4

7/4 + 3/5

Find the LCM of the denominator

Isaiah is working two summer jobs, making $16 per hour tutoring and $10 per hour clearing tables. Isaiah must earn at least $110 this week. Write an inequality that would represent the possible values for the number of hours tutoring, tt, and the number of hours clearing tables, cc, that Isaiah can work in a given week.

Answers

Answer:

16t + 10c > 110

Step-by-step explanation:

Cost of tutoring per hour = $16

So, cost of tutoring t hours = $16t

Cost of clearing tables per hour = $10

So, cost of clearing tables c hours = $10c

Since, Isaiah must earn at least $110 this week.

Therefore, the required inequality will be given as:

16t + 10c > 110

An arithmetic sequence has this explicit formula: an = 14 + (n - 1)3. What is the recursive formula?​

Answers

Answer:

[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + 3 with a₁ = 14

Step-by-step explanation:

The explicit formula for an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference, then

[tex]a_{n}[/tex] = 14 + (n - 1)3

has a₁ = 14 and d = 3

A recursive formula allows a term in the sequence to be found by adding d to the previous term, thus recursive formula is

[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + 3 , with a₁ = 14

Answer: 3234 cubic units

Step-by-step explanation:

Volume of cylinder: πr²h

The diameter of the cylinder is 14 units so the radius is 7 units.

Now we'll substitute.

π = 22/7

h = 21

πr²h

π × 7² × 21

22/7 × 49 × 21 = 3,234

The volume is 3,234 cubic units.

Sushi was thinking of a number. Sushi doubles it,then adds 20 to get an answer of 27.7 what was the original number

Answers

Answer:

3.85

Step-by-step explanation

7.7 divided by 2 = 3.85

So if you double 3.85 you get 7.7 and then add 20 to 7.7 then you get 27.7

Let the number they are thinking of be X.

They double x , which would be 2x.

They then add 20, which would be 2x +20

So you have 2x + 20 = 27.7

Now we can solve for x:

Subtract 20 from both sides:

2x = 7.7

Divide both sides by 2:

x = 7.7 / 2

x = 3.85

The original number was 3.85
