Bill plans to save for a pair of headphones that are 89.00.The sales tax rate is 8% how much will bill need to save

Answers

Answer: 96.12

Step-by-step explanation:

The amount that Bill will need to save will be for the cost of the headphones and the sales tax that will be applied. This will be:

= 89 + (8% × 89)

= 89 + (0.08 × 89)

= 89 + 7.12

= 96.12

Therefore, Bill will need to save 96.12.

(c) The annual membership fee in 2013 is $198 for each adult and $75 for each child.

Adult = 440 members
Children = 120 members

(i) Calculate the total amount the 560 members pay in 2013.


(ii) The adult fee of $198 in 2013 is 5.6% more than the fee in 2012.
Calculate the adult fee in 2012.​

Answers

Answer:

i ) $96120

ii ) Singular adult fee in 2012: $186.91

Step-by-step explanation:

( i )

To find the costs of all 560 peoples you:

Multiply the amount of people by the fee,

440 × 198 = $87120

120 × 120 = $9000

Add these go get the sum of member fees: $96120

( ii )

First calculate what 1% of the adult fee would be:

198 ÷ 100 = 1.98 = 1%

Then calculate what 0.1% of the fee:

1.98  ÷ 10 = 0.198 = 0.1%

Now multiply 5 by the value of 1% to get 5% :

5 × 1.98 = 9.9

Then multiply 6 by the  0.1% to get 0.6% :

0.198 × 6 = 1.188

Add these numbers together to get:

1.188 + 9.9 = $11.088 = 5.6%

Due to the fact this question is referring to money we will round this number 2 decimal places (as money does not exceed 2dp)

$11.09

We now subtract this from the 2013 fee to find out the 2012 fee

$198 - $11.09 = $186.91

$186.91 was the cost of a singular adult fee in 2012

In a school of 464 students, 89 students are in the band, 215 students are on sports teams, and 31 students participate in both activities. How many students are involved in neither band nor sports?
A.160 students
B.191 students
C.249 students
D.433 students

Answers

Answer:

191 students  B option is correct

Step-by-step explanation:

Total students=464

In band=89

sports teams=215

Number of students who participates in activities is

215+89=304

31 participate in  both activities so,

304-31=273

273 who participate in activities

Total students-273=Not involved in any activity

464-273=191

Each week, Joe earns $75 for tutoring plus $17.50 for each additional hour he tutors. His friend, Maddie earns $56 for tutoring plus $19.50 for each additional hour she tutors. Write an expression that represents the total they make altogether after tutoring for t hours.

Answers

Answer:

$75 + $17.50t

$56 + $19.50t

Step-by-step explanation:

Let us assume the number of hours be t

Now according to the equation

For Joe

= $75 + $17.50t

And, for Maddie

= $56 + $19.50t

The expression that represents the total is as

$75 + $17.50t

$56 + $19.50t

Hence, the above represent the answer and the same is relevant

2(x - 3) = 2x + 5     distribute by multiply 2 into the parenthesis.

2x - 6 = 2x + 5

-2x        -2x         subtract 2x on both sides, 2x's will cancel on both sides.

Since -6 = 5, there is no solution because -6 cannot equal to 5, which is a false statement. Thus, "C. There is no solution." is the correct answer. Hope this helps :)

Which equation is an identity?


A. –3y + 3 = –3y – 6

B. 9 – (2v + 3) = –2v – 6

C. 3w + 8 – w = 4w – 2(w – 4)

D. 7m – 5 = 8m + 7 – m

Answers

Answer:

i think B but I’m not 100% sure lol

Step-by-step explanation:

Here’s what I found on this app

3w + 8 - w = 4w - 2(w - 4)

2w + 8 = 4w - 2w + 8

2w + 8 = 2w + 8

0 = 0

Answer:  C. 3w + 8 – w = 4w – 2(w – 4)

Identity equations are equations that are true no matter what value is plugged in for the variable. If you simplify an identity equation, you'll ALWAYS get a true statement. Learn about identity equations in this tutorial, and then create your own identity equation.

Step-by-step explanation:  Algebra.com

a. 11 - (2v + 3) = -2v - 8

Simplify

    11 - 2v - 6 = -2v - 8

         5 - 2v = -2v - 8

Add 3v to both sides

              5 = -8

That's false, so it is not an identity.

b. 5w + 8 - w = 6w - 2(w - 4)  

Simplify

      4w + 8 = 6w - 2w + 8

      4w + 8 = 4w + 8

That's exactly the same on both sides, so it's

an identity.

       

c. 7m - 2 = 8m + 4 - m

  7m - 2 = 7m + 4

Subtract 7m from both sides:

      -2 = 4

That's false, so it is not an identity.

 

d. 8y + 9 = 8y - 3

Subtract 8y from both sides:

       9 = -3

That's false, so it is not an identity.

What is an inequality?

An inequality is an expression that shows the non equal comparison of two or more numbers and variables.

Let m represent the number of minutes Trina can run the water hose to add more water to the pond without adding the maximum amount in case of rain.

Hence:

(48/2)m < 256

24m < 256

The number of minutes Trina can run the water hose to add more water to the pond without adding the maximum amount in case of rain is 24m < 256
