The answer to your question

Jack and Jill each go out shopping.
Jack spends 1/3 of his money.
Jill spends 40% of her money.

Frank says Jack spent more because 1 /3 is greater than 40%.

Alice says you cannot tell who spent more.
Who do you agree with, Frank or Alice? Explain why.

Answers

I agree with Alice because it depends on how much money they had, which was not stated in the question.

I agree with Alice because you do not know how much money Jill and Jack had before they went shopping. If they had the same amount of money Jill would have spent more because 40 percent is greater than 1/3.

Step-by-step explanation:

whole numbers don't include negative numbers / integers

Answer:

the answer would be false

Step-by-step explanation:

This is because whole numbers are nothing but a set of positive integers which do not contain fractions and decimal values, but starts from zero. The negative integers like -5, -4 … are also not considered as whole numbers. They are represented as {0, 1, 2, 3…}.

Can somebody please help me with my math ?

Answers

Step-by-step explanation:

just plug in the numbers to the x values

if f(3) then ur equation would look like this f(3) = 4x - 5

then u solve it to get the answer.

  3 = 4x - 5

+ 5 = 4x + 5

------------------ ---> add 5 on both sides

 8 = 4x

now u just divide. 8 ÷ 4 = 2 so f(3) = 2

Find the equation of the line that goes through the points (12, 11) and (7,1)​

Answers

Answer:

8,4

Step-by-step explanation:

Step 1: Find the slope of the line.

Step 2: Use the slope to find the y-intercept.

Step 3: Use steps 1 and 2 to write the answer.

I will explain these steps by looking a several examples. Please understand that there are often several

different ways to complete each math problem, but I have found through the years that students are most

successful when the do problems the same way each and every time they attempt the problem. If you

know a different way to find the answer that is great, but I am going to show how to do the problem one

way and use the same technique everytime I see this problem.

Example 1: Find the equation of the line passing through the points (–1, –2) and (2, 7).

Step 1: Find the slope of the line.

To find the slope of the line passing through these two points we need to use the slope

formula:

( )

( )

So the slope of the slope of the line passing through these two points is 3.

Step 2: Use the slope to find the y-intercept.

Now that we know the slope of the line is 3 we can plug the slope into the equation and

we get:

y = 3x + b

Next choose one of the two point to plug in for the values of x and y. It does not matter

which one of the two points you choose because you should get the same answer in either

case. I generally just choose the first point listed so I don’t have to worry about which

one I should choose.

(–1, –2) → –2 = 3(–1) + b Multiply to simplify the problem.

–2 = –3 + b Solve for b and you will have the y-intercept.

b = 1

Answer:

  C.  x = 17.6

Step-by-step explanation:

The relevant relation between sides and angles is ...

  Tan = Opposite/Adjacent

  x = 11/tan(32°) ≈ 17.60

The appropriate choice is ...

  x = 17.6

Then you take the chance of having to stop at the second light which is 80%, and find the probability of NOT having to stop there, which is 20%, or .2. Then you multiply the probabilities of not having to stop, which equals  .14.

A clothing store is having a sale. A shirt normally sells for $30. The store is
offering a 15% discount. What is the discounted price?
A. $4.50
B. $25.50
C. $26.50
D. $24.50

Answers

Answer:

B. $25.50

Step-by-step explanation:

This is a bit of a trick question.

To find how much money is taken off the price, you would do 15% (0.15) • 30 and you get $4.50. This is the discount that is taken off of the price, not the discounted price. To find the new discounted price, subtract the $4.50 from $30.00.

$30.00 - $4.50 = $25.50

PLEASE ASNWER ASASP for braineslst!!!!!!!!!!!!!!!!!!Read this PoemThe Village BlacksmithHenry Wadsworth Longfellow - 1807-1882Under a spreading chestnut-tree The village smithy stands;The smith, a mighty man is he, With large and sinewy hands,And the muscles of his brawny arms Are strong as iron bands.His hair is crisp, and black, and long; His face is like the tan;His brow is wet with honest sweat, He earns whate'er he can,And looks the whole world in the face, For he owes not any man.Week in, week out, from morn till night, You can hear his bellows blow;You can hear him swing his heavy sledge, With measured beat and slow,Like a sexton ringing the village bell, When the evening sun is low.And children coming home from school Look in at the open door;They love to see the flaming forge, And hear the bellows roar,And catch the burning sparks that fly Like chaff from a threshing-floor.He goes on Sunday to the church, And sits among his boys;He hears the parson pray and preach, He hears his daughter's voiceSinging in the village choir, And it makes his heart rejoice.It sounds to him like her mother's voice Singing in Paradise!He needs must think of her once more, How in the grave she lies;And with his hard, rough hand he wipes A tear out of his eyes.Toiling,rejoicing,sorrowing, Onward through life he goes;Each morning sees some task begin, Each evening sees it close;Something attempted, something done, Has earned a night's repose.Thanks, thanks to thee, my worthy friend, For the lesson thou hast taught!Thus at the flaming forge of life Our fortunes must be wrought;Thus on its sounding anvil shaped Each burning deed and thought.Then answer this question:What part(s) of this poem reflect Henry Wadsworth Longfellows attempt to define American identity?
