The length of a rectangle is three times its width. The perimeter is 64 feet. What are the dimensions of the rectangle?
Answer:
8 and 24
Step-by-step explanation:
let width be X
then length will be 3x
2(3x+X)=64
3x+X=32
4x=32
X=8
then 3x=24
x+y+z=2

Does the following picture represent a linear function?
Answer: No
Step-by-step explanation: For x 0-2, the y is increasing by +5 every time. However, the moment it hits x=2, it starts decreasing by -5 every time. This means that it does not follow on set pattern (either +5 or -5) and looks more like a ^ than a /.
find the rate of change
Answer:
The rate of change represented in the table is 14
Step-by-step explanation:
rise over run or y2-y1/x2-x1 to find the rate of change
pick two points
lets use (0,-11) and (2, 17)
17 - (-11) / 2 - 0
= 28 / 2
= 14
Compare the decimal forms of 2/5 and 4/9
how are they alike and how are they different?
Answer:
These numbers are not the same as 4/9 is bigger than 2/5.
Step-by-step explanation:
As we have to compare the decimal forms of 2/5 and 4/9.
We determine that the numbers in decimal forms are:
[tex]\frac{2}{5}=0.4[/tex]
[tex]\frac{4}{9}=0.44444...\:[/tex]
so
[tex]\frac{4}{9}=0.44444[/tex] is clearly bigger than [tex]\frac{2}{5}=0.4[/tex].
Therefore, these numbers are not the same as 4/9 is bigger than 2/5.

There are 2 Violet balls and four pink balls in a bag if two balls or tomorrow and one after another then what is the possibility of getting a violet first and a think Max is the first ball joints replaced
Answer:
The probability is 2/9
Step-by-step explanation:
Here , we want to find the probability of getting a violet ball first and a pink ball secondly if the violet ball is replaced
probability = number of balls of same color/total number of balls
The total number of balls = (2 + 4) = 6 balls
Probability of selecting a violet = 2/6 = 1/3
Probability of selecting a pink afterwards with replacement = 4/6 = 2/3
So the probability of selecting the balls in that order will be;
1/3 * 2/3 = 2/9
factorise (6²+28ab+196a²)
Answer:
4(49a²+7ab+9)
Step-by-step explanation:
Use the figure below.
Select all the lines in the proof of △ABC≅△CDA that have the correct justification.
∠ACB≅∠CAD, Alternate Interior Angles Theorem
△ABC≅△CDA, SAS Triangle Congruence Theorem
∠BAC≅∠DCA, Alternate Interior Angles Theorem
AB || CD and BC || AD, ASA Triangle Congruence Theorem
AC≅AC, Reflexive Property of Congruence
Answer:
∠ACB≅∠CAD, Alternate Interior Angles Theorem
∠BAC≅∠DCA, Alternate Interior Angles Theorem
AC≅AC, Reflexive Property of Congruence
By A-S-A congruence, the △ABC≅△CDA.
Step-by-step explanation:
Given the figure:
We are given that:
Side BC || AD
Side AB || DC
Let us have a look at a few properties first.
Alternate Interior Angle Theorem: It states that when two parallel lines are cut by a line then the alternate angles which are on the interior side are equal to each other.
Reflexive Property of Congruence: It states that a side or angle is always congruent to itself.
Now, let us consider the triangles:
△ABC and △CDA.
Side BC || AD
Therefore,
∠ACB≅∠CAD, Alternate Interior Angles Theorem
Side AB || DC
Therefore,
∠BAC≅∠DCA, Alternate Interior Angles Theorem
Also, Side AC is common.
AC≅AC, Reflexive Property of Congruence
Therefore, by A-S-A congruence, the △ABC≅△CDA.

A high school is doing a fundraiser selling magazine subscriptions. The magazine publisher will pay the school a starting bonus of $500 and they $4 for each magazine subscription sold. At the end of the fundraiser the school is paid $1300. How many subscriptions did they sell?
Answer:
200
Step-by-step explanation:
You can use the equation 1300=4x+500
Starting bonus ($500) is like the y intercept so you would get that out of the way by subtracting 500 from both side
1300-500=800
500-500=0
Your equation is now:
800=4x
Now since the question is How many subscriptions did they sell and we know that each magazine is $4 all for have to do is divide both sides by 4 to get the answer.
800÷4=200
4x÷4=x
x=200

Alex bought a new aquarium. He is in the process of setting it up. The aquarium is in the shape
of a right rectangular prism and the dimensions, in inches, are 36 7/8 x 19 x 24 5/8. During
the set-up, Alex fills the aquarium with 6,039 in3 of water.
PLEASE HELP
Answer:
39.00%
Step-by-step explanation:
Given
Dimension: 36⅞ by 19 by 24⅝
Volume of Water = 6039in³
Required
What percent of the volume of the aquarium is filled with water?
First, we need to calculate the volume of the aquarium.
This is calculated by multiplying the dimensions of the aquarium
Volume = 36⅞ * 19 * 24⅝
Volume = 295/8 * 19 * 197/8
Volume = 1104185/64
Volume = 17252.89
The percent filled with water is calculated using the following formula:
%Percent = (Volume of water * 100%)/(Volume of aquarium)
%Percent = (6039 * 100%)/(17252.89)
%Percent = (603900%)/(17252.89)
%Percent = 39.00% (approximated)
Hence, the water occupies 39.00% of the aquarium

What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation y = Kx also represents direct proportionality. Here, K is called constant of proportionality. It is same as slope.
We have a plant grows at a constant rate.
The data recorded by Daniel is as follows -
Week 4 12 inches
Week 5 15 inches
Week 6 18 inches
The equation y = Kx also represents direct proportionality. Here, K is called constant of proportionality. We have to find the slope of the line represented by the data as -
K = slope
K = (15 - 12)/(5 - 4)
K = 3/1
K = 3
Therefore, the constant of proportionality is 3 inches/week.
