Answer:
The length of the rectangle is 6 centimeters
Step-by-step explanation:
The perimeter of a rectangle =
P = 2L + 2W
A rectangle has a perimeter of 38+x centimeters. The rectangle has a length of 3x−2 centimeters and a width of x centimeters.
Hence:
38 + x = 2(3x - 2) + 2(x)
38 + x = 6x - 4 + 2x
Collect like terms
38 + 4 = 6x + 2x - x
42 = 7x
x = 42/7
x = 6 centimeters
The length of the rectangle is 6 centimeters
At Brunswick Elementary school, 2/5 of six-grade students have at least one pet. If school has 181 sixth graders, about how many sixth graders own pets?
Answer: 72.4

Emma decided to bake cookies. Her recipe called for 3 cups of sugar and 4 cups of chocolate chips for 2 batches of cookies. If she made 12 batches of cookies, how many cups of chocolate chips does Emma need?
Answer:
24 cups of chocolate chips
Step-by-step explanation:
Since this is a proportion problem and there is only one variable that needs to be found we can use the Rule of three to solve this problem. To do this we simply divide the diagonal values by the last value which would ultimately give us the value of the variable in question, like so...
4 cups of chocolate chips <=======> 2 batches of cookies
x cups of chocolate chips <=======> 12 batches of cookies
(4 * 12) / 2 = 24 cups of chocolate chips
Therefore, we can now see that we would need a total of 24 cups of chocolate chips to make the 12 batches of cookies.

A quantity with an initial value of 840 decays continuously at a rate of 5% per day. What is the value of the quantity after 10 weeks, to the nearest hundredth?
Answer:
25.37
Step-by-step explanation:
Write a function:
f(t)=840e^{rt}
f(t)=840e
rt
Continuously uses Pe^(rt)
-0.05
r: decays 5%→−0.05
per day
f(t)=840e^{-0.05t}
f(t)=840e
−0.05t
(where t is in days)
10 weeks→10⋅7→70 days
There are 7 days in a week
Plug in t=70
f(70)=840e^{-0.05(70)}
f(70)=840e
−0.05(70)

Water runs from a hose into a bucket at a steady rate. The amount of water in the bucket for the time it is being filled is shown in the graph. “There are ____ gallons in the bucket after ____ seconds.”
Answer:
5 seconds 12 gallons of water
Step-by-step explanation:
since 5 equals 12 ur gonna divide the 12 into 3 split in in hakves then it will get u to 6 ow with 6 divide by 7 then aadd 8 the 8 will round up to 10 then 10 u have to split so thats 5 then 5 is gonna go intpo 9 then 9 will be divided into 7 so 9 divided by 7 is 1 2/7 now u take that and divide by 2 which is 0.2 then add 50 then subtract 50 then youll gett .2 then minus the 2 then u get 0.
The graph is the diagrammatic representation of a function thus the amount of water at the end of filling or at time 12 seconds is 5 gallons.
What is a graph?A graph is a diametrical representation of any function between the dependent and independent variables.
For example, y = x² forms a parabola now by looking at only the graph we can predict the behavior of the function.
As per the given graph of the amount of water and time.
The graph is linear showing a steady rate.
The graph is finishing at the extreme right at coordinate (12,5) where 12 seconds and 5 are gallons.
So, at the end of the filling, the time taken is 12 seconds and the amount of water is 5 gallons.
Hence "The graph is the diagrammatic representation of a function thus the amount of water at the end of filling or at time 12 seconds is 5 gallons".

what is the equation of this graphed Line enter your answer in slope-intercept form in the Box
Answer:
y = -1/3x - 5Step-by-step explanation:
Given line with points (-6, -3) and (6, -7)
Slope intercept form:
y = mx + bWe can see on the graph that y-intercept is b = -5
The slope is found using slope formula:
m = (y2 - y1)/(x2 - x1)m = (-7 - (-3))/(6 -(-6)) = -4/12 = -1/3Th equation is:
y = -1/3x - 5Which statement is true about this argument?
Premises:
If a quadrilateral is a square, then the quadrilateral has four right angles.
Quadrilateral JKLM has four right angles.
Conclusion:
Quadrilateral JKLM is a square.
The argument is not valid because the conclusion does not follow from the premises.
The argument is not valid because the premises are not true.
The argument is valid by the law of detachment.
The argument is valid by the law of syllogism.
Answer: The argument is valid by the law of detachment
Step-by-step explanation:
The law of detachment simply states that when the hypothesis is true, then the conclusion must also be true.
In this case, the argument is valid since the conclusion that "Quadrilateral JKLM is a square" follows from the argument that "a quadrilateral is a square, then the quadrilateral has four right angles".
The law of detachment is expressed here.

Given that;
The coordinate of L is (2, 2),
Then, the coordinates of L' is (-2, -2).
And, the coordinates of N is (1, 6),

A scientist is studying the growth of a radicus plant. The plant has an initial height of 20cm and grows at a rate of 4% monthly. Part A: Write an equation to model the growth of the plant. Part B: Find the height of the plant after 5 months.
Step-by-step explanation:
A) Given the initial height of plant = 20cm
Percent increase monthly = 4%
increment after x month = (4% of 20)x
increment after x month = (0.04*20)x
increment after x month = 0.8x
The height after x month = initial height + increment
The height after x month = 20 + 0.8x
Hence an equation that model the growth of the plant is 20+0.8x
B) To get the height of the plant after 5 months, we will substitute x = 5 into the modeled equation in A as shown;
H(x) = 20+0.8x
H(5) = 20 +0.8(5)
H(5) = 20+4
H(5) = 24cm
hence the height of the plant after 5minths is 24cm

Solve for 1/3(8x-5)-4=-3
Let's solve your equation step-by-step.
13(8x−5)−4=−3
Step 1: Simplify both sides of the equation.
13(8x−5)−4=−3
(13)(8x)+(13)(−5)+−4=−3 (Distribute)
83x+−53+−4=−3
(83x)+(−53+−4)=−3 (Combine Like Terms)
83x+−173=−3
83x+−173=−3
Step 2: Add 17/3 to both sides.
83x+−173+173=−3+173
83x=83
Step 3: Multiply both sides by 3/8.
(38)*(83x)=(38)*(83)

Consider two forces of 17 and 42 pounds both acting in the horizontal direction on a single object.
Find the Resultant force acting on the object.
A. Magnitude
B. Direction angles
Answer:
59,0
Step-by-step explanation:
Trust me also on edge
The Magnitude of forces is 59 pounds and Direction angles of forces is 0
What is magnitude of two forces?The magnitude of force refers to the sum of all the forces that are acting on an object. If all the forces are acting in the same direction, then the magnitude of the force increases. If the forces are acting on an object in different directions, then the magnitude of the force decreases.
What is direction of angles of two forces?To find the resultant force subtract the magnitude of the smaller force from the magnitude of the larger force. The direction of the resultant force is in the same direction as the larger force.
According to the question
Two forces of 17 and 42 pounds both acting in the horizontal direction on a single object.
i.e,
F1 = 17 pounds
F2 = 42 pounds
Now,
As, magnitude of force refers to the sum of all the forces
Direction is also same
Magnitude : 17 + 42 = 59 pounds
Now,
The Direction angles : 0
As they are having same direction so angle will be 0 .
Hence, The Magnitude of forces is 59 pounds and Direction angles of forces is 0
