The length of a rectangle is twice its width. the perimeter is 60 ft. find its area.

1 answer:

5 0

I hope this helps you

width w

lenght 2w

perimeter =2 (width +length )

60=2 (w+2w)

30=3w

w=10

Area= 2w.w

Area = 2.10.10

Area =200

tester [92]

Answer:

a) The value of the Annual Payment is A=$17,258.80

b) Is the picture in the attachment file

c) As you can see it in the picture with each payment, balance comes down, due it is the interest base, Interest portion comes down too.

Step-by-step explanation:

a) First of all, we are going to list the Knowns: $VP=47000$ , $i=5$ % and $n=3$ , Then we can use $A=\frac{VP}{\frac{1-(1+i)^{-n} }{i} } =\frac{47000}{\frac{1-(1+0.05)^{-3} }{0.03} }=17258.80$ . So this is the value of the Annual Payment

Which set of ordered pairs represents a function? {(−1,−3),(0,−7),(3,3),(3,−4)} {(7,9),(−5,7),(−5,8),(4,−4)} {(−6,−1),(−8,4),(−5

Jlenok [28]

Ordered pair{(−6,−1),(−8,4),(−5,4),(3,−9)} from the given set of ordered pairs represents the function.

As given in the question,

Given set of ordered pairs following is the one which represents the function :

{(−1,−3),(0,−7),(3,3),(3,−4)}

In the given set of ordered pair for input value 3 there are two outputs 3 and -4 , therefore it is not a function.

{(7,9),(−5,7),(−5,8),(4,−4)}

In the given set of ordered pair for input value -5 there are two outputs 7 and 8 , therefore it is not a function.

{(−6,−1),(−8,4),(−5,4),(3,−9)}

In the given set of ordered pair each input has unique single output. Therefore it is a function.

{(−1,0),(−1,−4),(8,−3),(−4,−6)}

In the given set of ordered pair for input value -1 there are two outputs 0 and -4 , therefore it is not a function.

Therefore, ordered pair{(−6,−1),(−8,4),(−5,4),(3,−9)} from the given set of ordered pairs represents the function.

A researcher measures daily driving distance from college and weekly cost of gas for a group of commuting college students. What

juin [17]

Answer:

There is a positive correlation between these two variables.

Step-by-step explanation:

Positive correlation is an association amid two variables in which both variables change in the same direction.

A positive correlation occurs when one variable declines as the other variable declines, or one variable escalates while the other escalates.

As the distance covered by the vehicle increases the amount of gas consumed also increases. Thus, the weekly cost of gas will also increase.

Thus, there is a positive correlation between these two variables.

The ratio of boys to girls at King Middle School is 3:2. What is the ratio of girls to all

NeX [460]

The answer is: " 2 :5 " ; or, write as: " 2/5 " .

________________________________________________________

The ratio of 'girls' to 'all students' is: "2: 5 " ; or, write as: " 2/5 ".

________________________________________________________

Explanation:

________________________________________________________

Given: The ratio of boys to girls is: " 3:2 " .

Problem: Find the ratio of "girls" to "all students:

________________________________________________________

Note: This ratio of "boys to girls", which is " 3 : 2 " ;

________________________________________________________

→ can be expressed as " 3x: 2x" ;

in which the total number of students is: " 3x + 2x " = 5x " .

→ The total number of students is represented as: " 5x " .

________________________________________________________

→ The ratio of "girls to boys" is: "2x : 3x" .

→ {that is; the "inverse" of the ratio of "boys to girls"} ;

→ {that is; the "inverse" of " 3x: 2x" } ; → which is: " 2x : 3x " .

________________________________________________________

The ratio of "girls" to "all students" is: "2x : 5x " ; or " 2x/5x " ;

→ Both "x" values cancel ; {since: " x/x = 1 "} ;

_________________________________________________________

→ and we have the answer: " 2 :5 " ; or, write as: " 2/5 " .

_________________________________________________________

The ratio of 'girls' to 'all students' is: " 2 :5 " ; or, write as: " 2/5 ".
