Answer:
Width = 27
Length = 9
*You might of switched width and length around please check*
Step-by-step explanation:
Width = 3x
Length = x
Perimeter Formula
2(3x+x) = 72
2(4x) = 72
8x = 72
x = 9
Since X was found, plug it in to find the width and length
3(9) = 27
x = 9

A pet store sold 36 Siamese cats. If the ratio of Siamese cats to house cats sold was 4:9, what is the combined amount of cats sold
The combined amount of cats sold is 117.
Ratio expresses the relationship between two variables. It shows the frequency of which that one value is contained within another variable.
The ratio of Siamese cats to house cats = 4 : 9
Number of Siamese cats = 36
Number of combined cats = c
This equation can be formed using the above information:
4/13 x c = 36
4c = 468
c = 468 / 4
c = 117

Ryan wants to measure the length of a bed cover which of the following would be the most appropriate unit to use?
A) kilogram
B) kilometer
C) meter
D) mile
The answer is meter since grams is used to measure weight and kilometer and mile are used to measure something larger.
Answer:
C. Meter
Step-by-step explanation:
1. Kilograms measure weight, not distance/length, so it wouldn't make sense to use them to measure a bed.
2. Kilometers are used to measure very long distances, as are miles, so it wouldn't make sense to use them on something small like a bedframe.
That means the only option left is C. Meter.

Haynes High School chartered buses for 60 students to go on a field trip. Valley High School chartered buses for 80 students.
*The total cost of the buses was the same for the two schools
*Students from Valley High School paid $5 less than students from Haynes High School.
What was the cost per student for Haynes High School?
A. $5 B. $15 C. $20 D. $40
Answer: $20
Step-by-step explanation:
Let 'x' be the cost of a ticket at Haynes
Let 'y' be the cost of a ticket at Valley
Since the total cost from both schools are the same, we can write it as:
[tex]60x=80y[/tex]
Since the cost of tickets at Valley was $5 less than Haynes, we can write it as:
[tex]y=x-5[/tex]
Now we have two equations, we can use to substitute into the other expression:
[tex]60x=80y[/tex]
[tex]60x=80(x-5)[/tex] we substitute y in this equation with the other equation
[tex]60x=80x-400[/tex]
[tex]-20x =-400[/tex]
[tex]x = 20[/tex]
Therefore the cost of the ticket at Haynes is $20 and the cost of the ticket at Valley is $15.

What is the slope of the line containing (-2, 5) and (4, -4)?
Answer:
B. - 3 / 2
Step-by-step explanation:
Let,
( x1, y1 ) = ( - 2, 5 )
So,
x1 = - 2
y1 = 5
( x2, y2 ) = ( 4, - 4 )
So,
x2 = 4
y2 = - 4
Formula : -
Slope = ( y2 - y1 ) / ( x2 - x1 )
Slope = ( - 4 - 5 ) / ( 4 - ( - 2 ) )
= - 9 / ( 4 + 2 )
= - 9 / 6
Slope = - 3 / 2
Answer:
B
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, 5 ) and (x₂, y₂ ) = (4, - 4 )
m = [tex]\frac{-4-5}{4-(-2)}[/tex] = [tex]\frac{-9}{4+2}[/tex] = [tex]\frac{-9}{6}[/tex] = - [tex]\frac{3}{2}[/tex] → B
803 to 2:12
1,460 to 4:00
753 to 1:30
are these proportional?!?
Answer:
no
Step-by-step explanation:
In terms of area per hour, Bob's works at the rate of ...
1460 ft²/(4 h) = 365 ft²/h
Rhonda's rate is ...
753 ft²/(1.5 h) = 502 ft²/h
The rates are different, so they are not proportional.
___
Additional comment
Toni's rate is 803 ft²/(2.2 h) = 365 ft²/h . . . the same as Bob's
Bob's and Toni's rates are proportional.

A taxicab charges $3.00 per person
plus $1.25 per mile. What is the
greatest distance one passenger
could travel with a budget of
$28.00?
Answer:
I believe the answer would be 20 miles max for one passenger.
Step-by-step explanation:
This is because if you create an equation out of this, knowing that only one passenger will be riding, you will get:
$3.00+$1.25x=$28 ($3 added too $1.25 times the number of miles (x) which equals the total amount you have ($28)).
x being the number of miles (so we need to calculate for x)
$3 + $1.25x = $28
-subtract 3 on both sides-
$1.25x=$28-$3
$1.25x=$25
-divide by 1.25 on both sides-
x=$25/$1.25
x=20 miles
Not sure if all calculations are correct, but I hope this helps :)!

What is the Distance formula of (-6, -12) and (4,8)
Distance formula is in picture
Answer:
The distance formula is 22.360679775
if you round it to the nearest tenth, then the answer is 22.4
Step-by-step explanation:
(-6, -12) and (4,8)
(x2 - x1)² + (y2 - y1)²
Place the x and y values
(4 - - 6)² + (8 - - 12)²
= 10² + 20²
= 100 + 400 = 500
√500 = 22.360679775
Round it to the nearest tenth and you will get 22.4

[tex] \sf{(x_1, y_1) = (-6, -12)}[/tex][tex] \sf{(x_2, y_2) = (4, 8)}[/tex]Substitute the given values into the distance formula and solve for d:

Answer:
The function is 200+50t (t= # of months)
Step-by-step explanation:
The best way to do this is to look at the question, and see no matter what, we have to pay 200 dollars to start. After which, they charge 50 bucks a month. Knowing this, we can make a function using f(x). Let C(t)= cost. Included is that graph. So for these questions, we need to see that there is an independent and a dependent variable, and we need to see that cost is affected by time. Hope this helps.
