The perimeter of a college basketball court is 96m and the length is 14me more than the width. what are the dimesions?​
Margaret [11]

Step-by-step explanation:

let width =x

length=x+14

....

perimeter=96=2*(L+W)

96=2*(X+X+14)

96=4x+28

96-28=4x

68=4x

/4

68/4=x

17=x the width

length = 17+14=31m

....

Check

17+17+31+31=96

I hope it's helpful!

in the game of hearts, four players are each dealt 13 cards from a deck of 52. is this a function? if so, what are the domain an
skelet666 [1.2K]

Based on the fact the game of hearts, four players are each dealt 13 cards from a deck of 52

  • The domain is the deck of 52 cards
  • codomain is 4 players
  • function, f(k) maps a card to each player
  • It is surjective

This is further explained below.

<h3>What is a surjective Function?</h3>

A surjective function is a kind of function that exists in mathematics that ensures that any element y may be transferred to element x in such a way that f(x) equals y.

To put it another way, each element that makes up the function's codomain is the mirror image of at least one element that makes up the domain.

Generally, function, f(k) maps a card to each player

And since each player is dealt 13 cards st 13 of the cards are mapped to each player.

It is a function as one card is mapped to one and only one player.

The function is not injective because 13 cards 1 are mapped to one player so it is a many-one function but the injective function does not map two elements to a common clement.

In conclusion, It is surjective as each player is dealt 13 cards. the function is not injective hence rot bijective.

Cary claimed that the expression − 5 + m − 5 + m is negative. Determine whether Cary's claim is always true, sometimes true, or
atroni [7]

Answer:

The given Expression is sometimes true.

Step-by-step explanation:

from the question,

The given expression by Cary is   -5 + m -5+ m.

So, solving the expression we get

     ⇒            -10+2m

                     Let m is an integer.

Whenever,  

                   (a)    m < 5                             { m = 4,3,2,1,0,-1,-2.......................}

                  The given Expression always gives negative value.

                  (b)     m\geq 5                             {m = 5,6,7,8,9.......................}

                  The given Expression always gives positive value.

Here, we get that the given Expression is not providing the Negative value always, that's why it is not always true and can't be never true.

Hence,

According to Cary's claimantion the given Expression is sometimes true.

Rewrite the division problem as multiplication:
Pani-rosa [81]

Answer:

What is the problem??? If you didn't need an actual problem solved I said how to do it.

Drea and Sajini both worked at a local ice cream shop over the summer. Together, they earned a total of $425. Drea earned $25 mo
Oksi-84 [34.3K]

Answer:

Sajini = 200

Drea = 225

Step-by-step explanation:

d = amount Drea earned

s = amount Sajini earned

Together they earned 425

d+s =425

d = s+25


The system of equations

d+s =425

d = s+25


I will use substitution to solve

Substitute d= s+25 into the first equation

d+s =425

(s+25) + s = 425

Combine like terms

2s+25 =425

Subtract 25 from each side

2s+25-25 =425-25

2s = 400

Divide by 2

2s/2 =400/2

s =200

Sajini = 200

Now we need to find d

d = s+25

d = 200 + 25

d = 225

Drea = 225
