Fiona is going to the grocery store for watermelons and pineapples. Watermelons cost $7 each and pineapples cost $4 each. Fiona has a total of $30 to spend. Use the equation 7w + 4p = 30 to answer the question below. If Fiona buys 3 watermelons, what is the maximum number of pineapples she can buy?

Answers

Answer 1

Answer:

The maximum number of pineapples Fiona can buy is 2.

Step-by-step explanation:

If Fiona buys 3 watermelons, thats 7 x 3 = 21. Then, (total amount of money) 30 - 21 = 9. To find how many pineapples she can buy, see how many times 4 goes into 9 (which is 2). Hope this helps!

Answer 2

Answer:

9.

Step-by-step explanation:

7x3=21, 30-21=9

3x=12, then 3x/3=12/3. X = 4

Answer:

3x + 2 = 14

3x + 2 - 2 = 14 - 2

3x = 12

3x/3 = 12/3

x = 4

Step-by-step explanation:

3x + 2 = 14

subtract 2 from both sides

3x + 2 - 2 = 14 - 2

combine like terms.

3x = 12

divide both sides by 3

3x/3 = 12/3

x = 4

I have that same question on my extra credit!

Step-by-step explanation:

I know the answer its 160.55 but I don't know what i should do for the problem. This is my questions:

Mina asked four friends to explain how each one solved the expression . Here are their explanations Please comment if these are the same:

Ivy’s explanation: I lined up the numbers to subtract.

 176.3

- 15.75

 18.8

Hannah’s explanation: I lined up the two decimals according to place value. I put a 0 in the hundredths place to make it easier for me to subtract.

 176.30

- 15.75_

 161.45

Jose’s explanation: I lined up the two decimals according to place value.

176.3

- 15.75

 161.45

An’s explanation: I counted up from 15.75 to 176.3 to find the difference. I underlined each number I added on each line.

15.75 + 0.25 = 16

16 + 4 = 20

20 + 150 = 170

170 + 6 = 176

176 + 0.3 = 176.3

I rearranged the underlined numbers to make them easier to add: .

150 + 6 + 3 + 0.25 = 163.25

The longer leg of the right triangle is 8 more than the shorter leg. The hypotonuse is 8 more than the longer leg. FInd all 3 sides

Answers

Answer:

4[tex]\sqrt{13}[/tex]

4[tex]\sqrt{13}[/tex] + 8

4[tex]\sqrt{13}[/tex] + 16

Step-by-step explanation:

as per the given information:

shorter leg = x

longer leg = x + 8

hypotonuse = x + 8 + 8

remember the Pythagorean theorem, which states

x^2 + y^2 = n^2

where x and y are the legs and n is the hypotenuse

so now one can set up an equation:

x^2 + ( x + 8 )^2 = ( x + 16 ) ^2

simplify and solve using inverse operations:

first preform the square

x^2 + x^2 + 16x + 64 = x^2 + 32x + 256

then preform inverse opertations and simplify

2x^2 + 16x + 64 = x^2 + 32x + 256

-x^2                       -x^2

x^2 + 16x + 64 = 32x + 256

       -16x            -16x

x^2 + 64 = 16x + 256

       - 64             -64

x^2 = 16x + 192

-16x     -16x

x^2 - 16 = 192

x^2 -4^2 = 192

remember the differnt ways of writing a special square

(x - 4) (x + 4) = 192

x = 4[tex]\sqrt{13}[/tex]

now add 8 to find the longer leg

4[tex]\sqrt{13}[/tex] + 8

an add another 8 to find the hypotenuse

4[tex]\sqrt{13}[/tex] + 8 + 8

4[tex]\sqrt{13}[/tex] + 16

A coordinate grid with 2 lines. The first line is labeled f(x) and passes through (negative 4, 3), (0, 3) and (4, 3). The second line is labeled g(x) and passes through the points (negative 2, negative 5), (0, negative 2), and (2, 1)

Determine the input value for which the statement

f(x) = g(x) is true.


From the graph, the input value is approximately (2) (2.5) (3.5) or (4)

f(x) = 3 and g(x) = 3/2x – 2


3 = 3/2x – 2

Answers

Answer:

The answer is Beth.

Step-by-step explanation:

It states "Becky is not Sleeping Beauty and went trick-or-treating with Snow White" so we know that its not Becky. It also states "Beth and Sleeping Beauty are sisters" so we know that Beth is not Sleeping Beauty and we know that Becky is not Sleeping Beauty or Snow White. So it means that Barbara is Sleeping Beauty, Becky is Cinderella and Beth is Snow White.

Oh(x) = x + 4
Oh(x) = x - 4
h(x) = x
Oh(x) = = x

Answers

Answer:

y = x/4

Step-by-step explanation:

First, replace f(x) with y, so it's easier to find the inverse:

y = 4x

To find the inverse of this function, you would replace all the y's with x's and all the x's with y's, and then solve for y. That would be:

x = 4y

y = x/4

Therefore, the inverse function of y = 4x is y = x/4.

Problem 16-05 To generate leads for new business, Gustin Investment Services offers free financial planning seminars at major hotels in Southwest Florida. Gustin conducts seminars for groups of 25 individuals. Each seminar costs Gustin $3300, and the average first-year commission for each new account opened is $5100. Gustin estimates that for each individual attending the seminar, there is a 0.01 probability that he/she will open a new account. Determine the equation for computing Gustin’s profit per seminar, given values of the relevant parameters. Round your answers to the nearest dollar. Profit = (New Accounts Opened × $ 5100 ) – $ 3300 What type of random variable is the number of new accounts opened

Answers

Answer:

1) The equation for computing Gustin's profit per seminar is given as follows;

The profit = (The number of Newly Opened Accounts) × Commission - Seminar cost

2) The number of new accounts is a continuous random variable

Step-by-step explanation:

1) The number of individuals that attend each of Gustin's seminar = 25 individuals

The cost of each seminar = $3,300

On average the commission on the first-year for each opened account = $5,100

The probability of opening an account by an attendee of each seminar = 0.01

The profit = Revenue - The cost of each seminar

The revenue = (The number of Newly Opened Accounts) × (Commission on each account)

∴ The revenue = (The number of Newly Opened Accounts) × $5100

Therefore, the equation for finding Gustin's profit per seminar is given as follows;

The profit = (The number of Newly Opened Accounts) × Commission - Seminar cost

The profit = (The number of Newly Opened Accounts) × $5100 - $3,300

The number of Newly Opened Accounts = (The number of attendee) × (The probability of an attendee opening an account)

The number of Newly Opened Accounts = 25 × 0.01 = 0.25

The number of Newly Opened Accounts = 0.25

The profit = 0.25 × $5100 - $3,300

The revenue = 0.25 × $5100 = $1,275

The profit = $1,275 - $5,100 = -$3,825 = ($3,825)

2) The number of Newly Opened Accounts = 0.25 which gives, that Gustin has to conduct 4 seminars to be sure of 1 new account, which represents a probabilistic variable which is the definition of a continuous random variable.

Therefore, the number of new accounts is a continuous random variable.

Answer:If the question is asking for 9/10/3/5 the answer is 3/50; however, if the question is asking for (9/10) / (3/5), the answer should be 3/2.

Step-by-step explanation: The 3/50 answer comes from 9/10 which equals .9, dividing that by 3. That equates to .3, and then dividing by 5 which measures up to .06. From there you can turn .06 into a fraction being 3/50.

You get the 3/2 by dividing (9/10) by (3/5). .9/.6 is 1.5. When converted to a fraction 1.5=3/2. Hope this could help.

v / 1/2 πr² = 1/2 πr²h / 1/2 πr² (Divide both sides of the equation by 1/2 πr² to find the formula for height (h).

v / 1/2 πr² = h or h = 2v / πr²
