The length of a rectangle is 6 inches more than it’s width. if the perimeter of the rectangle is 24 inches, find the dimensions. create let statement and write equation.
Answer:
The dimensions of the rectangle are;
Width = 3 inches
Length = 9 inches
Step-by-step explanation:
Given;
Perimeter of the rectangle is 24 inches Length is 6 inches more than the widthWe want to determine the dimensions of the rectangle;
Let the width of the rectangle be x inchesThis means, the length of the rectangle will be (x+6) inchesBut, Perimeter = 2(L+W)Forming an equation, we get;
2 ( x + x + 6) = 24
4x + 12 = 24
With the equation we can solve for x
4x = 24 - 12
4x = 12
x = 3
and (x + 6) = 9
Therefore;
Width = 3 inches
Length = 9 inches
The width of the rectangle is 3 inches and the length is 9 inches.
Let's assume that the width of the Rectangle dimensions is represented by 'w' inches.
Since the length is 6 inches more than the width, we can represent it as 'w + 6' inches.
The perimeter of a rectangle is the sum of all its sides.
In this case, the formula for the perimeter is 2(w + l), where w represents the width and l represents the length.
So, for this problem, we have the equation 2(w + w + 6) = 24.
Simplifying this equation, we get 4w + 12 = 24.
Solving for 'w', we find that the width is 3 inches.
Plugging this value back into the equation for the length, we find that the length is 9 inches.

In the graph of an inequality, the region below a dashed line through the points (4, 3) and (0, 2) is shaded. What inequality does the graph represent?
Answer:
The inequality that represents the graph is y < [tex]\frac{1}{4}[/tex]x + 2
Step-by-step explanation:
i) the region below a dashed line through the points (4,3) and (0,2) is shaded.
ii) first we find the equation of the line passing through the points (4,3) and (0,2)
(y - 3) = [tex](\frac{3 - 2}{4 - 0})[/tex](x - 4) ⇒ y - 3 = [tex]\frac{1}{4}[/tex](x - 4)
⇒ 4y - 12 = x - 4 ⇒ 4y = x + 8 ⇒ y = [tex]\frac{1}{4}[/tex]x + 2
iii) for the area shaded below the line whose equation is given in ii) above the inequality that will represent the shaded region is given by
y < [tex]\frac{1}{4}[/tex]x + 2
The graph represents the inequality y < 1/4x + 2. The inequality was calculated based on the information given: points the line goes through, shading below the line, and the line being dashed all determine the inequality's form.
Explanation:To determine the inequality graphed, we first need to find the equation of the line. The line passes through the points (4, 3) and (0, 2), so we can use these points to find the slope of the line.
The formula for the slope (m) is [tex](y2 - y1)/(x2 - x1).[/tex]. Plug in the coordinates of the two points into this formula: ([tex]3 - 2) / (4 - 0) = 1/4[/tex] So, our slope is 1/4.
Given a slope (m) of 1/4 and the y-intercept (b) of 2, we can write the equation of the line in slope-intercept form (y = mx + b) as y = 1/4x + 2.
One key part of your question is that the region below this line is shaded. In the language of inequalities, shading below the line corresponds to 'y is less than' the line's equation. Also, the line is dashed, meaning that the points on the line are not included in the solution, which we denote as 'less than' rather than 'less than or equal to'.
So, the inequality represented by this graph is y < 1/4x + 2.

Mr Edwards buys 2 new knobs for each of his kitchen cabinets. How many knobs does he buy?
Answer:
Step-by-step explanation:
You need to find out how many cabinets it is
Final answer:
To determine how many knobs Mr. Edwards needs to buy for his kitchen cabinets, we need to know the total number of cabinets since he needs 2 knobs for each cabinet.
Explanation:
Mr. Edwards wants to buy new knobs for his kitchen cabinets. To determine how many knobs he needs to buy, we would need to know the exact number of kitchen cabinets he has. However, the information about Chelsea and her trip to Europe, her being a shop-a-holic and physics lover, and the estimation of the number of pairs of shoes that can fit in her closet seem to be unrelated to Mr. Edwards's question. Therefore, to answer Mr. Edwards's query, we need the number of cabinets to calculate the total number of knobs. If there are X cabinets, Mr. Edwards would need to purchase 2X knobs.

A bag of Chocolates is labeled to contain 0.384 pounds of chocolate the actual weight of the chocolate is 0.3798 pounds. How much have you or lighter are the chocolates and The started on the label. Show your reasoning
Answer:
The actual weight is 1.1% less (100 - 98.9) than the labeled weight.
Step-by-step explanation:
1. Let's review the information given to us to answer the question properly:
Labeled weight of the bag of chocolates = 0.384 pounds
Actual weight of the bag of chocolates = 0.3798 pounds
2. How much have you or lighter are the chocolates and the stated on the label. Show your reasoning.
Let's find how much we have comparing the labeled weight and the actual weight, using a Direct Rule of Three, this way:
Weight Percentage
0.384 100 %
0.3798 x %
0.384x = 0.3798 * 100
0.384x = 37.98
x = 37.98/0.384
x = 98.9 (Rounding to one decimal place)
The actual weight is 1.1% less (100 - 98.9) than the labeled weight.
The chocolates are 0.0042 pounds lighter than what is stated on the label.
Explanation:The difference in weight between the labeled weight and the actual weight of the chocolates is 0.0042 pounds. This means that the chocolates are 0.0042 pounds lighter than the label indicates.
To calculate this, subtract the actual weight from the labeled weight: 0.384 - 0.3798 = 0.0042 pounds.

trent has a collection of 198 baseball and basketball training cards. he has 4.5 times as many baseball cards as basketball cards. how many baseball cards does trent have in his collection?
There are 162 base ball cards
Solution:
Let "a" be the number of baseball training cards
Let "b" be the number of basket ball training cards
Trent has a collection of 198 baseball and basketball training cards
Therefore,
a + b = 198 -------- eqn 1
He has 4.5 times as many baseball cards as basketball cards
Number of baseball cards = 4.5(number of basketball cards)
a = 4.5b --------- eqn 2
Let us solve eqn 1 and eqn 2
Substitute eqn 2 in eqn 1
4.5b + b = 198
5.5b = 198
b = 36
Substitute b = 36 in eqn 2
a = 4.5(36)
a = 162
Thus there are 162 base ball cards
Trent have 162 baseball cards in his collection.
Trent has a collection of 198 baseball and basketball training cards, with baseball cards being 4.5 times as many as basketball cards. To find out how many baseball cards Trent has, we can set up a system of equations.
Let x be the number of basketball cards.
Since the number of baseball cards is 4.5 times the number of basketball cards, the number of baseball cards is 4.5x.
The total number of cards is 198, so x + 4.5x = 198.
Solving this equation, we find x = 36. Therefore, the number of baseball cards Trent has is 4.5*36 = 162 baseball cards.

The derivative of tanx in calculus is sec^2x, which represents the slope of the curve at any point x for the function tanx.
Explanation:The derivative of a function measures how the function changes as its input changes. In calculus, the derivative is a concept that describes the rate at which a quantity changes.
In the context of your question, the derivative of tanx or tangent x is sec^2x or secant squared x. This is a standard result that is usually memorized in calculus courses and can be derived using the limit definition of the derivative and trigonometric identities.
To put it in simpler terms, if tanx were the equation of a curve, the derivative (sec^2x) would represent the slope of that curve at any point x. This is key to understanding how the function behaves at different points and predicting its future behavior.

The relationship between the number of months after the first year and the amount remaining on the card is .
The independent variable is the _____________?
The dependent variable is the ______________?
Answer:
The relationship between the number of months after the first year and the amount on the remaining card is linear and inverse (which means that, when the number of montsh after the first year increases, the amount on the remaining car decreases, in a linear way).The independent variable is the numbers of months after the first year.The dependent variable is the amount on the remaining card, because this amount depends on the time it has passed since the first year (which is our independent variable!).If we call "y" our dependent variable, and "x" our independent variable, this relationship can be written as y=25 - 2.5x. If no months has passed since the first year, then x=0 and the amount in the card equals $25, while if one month has passed since the first year x=1 and y=22.5 (the amount in the card in this case is $22.5).Answer:
The relationship between the number of months after the first year and the amount remaining on the card is discrete
The independent variable is the

Zack watered his garden with 1 3/8
gallons of water the first week he planted it. He
watered it with 1 3/4 gallons the second week, and
2 1/8 gallons the third week. If he continued watering
in this pattern, how much water did he use on the
fifth week?
A 22 gallons
© 34 gallons
B 27 gallons
0 6 gallons
Answer:
The correct answer is that Zack used 2 7/8 gallons to water his garden on the fifth week.
Step-by-step explanation:
Let's find out the pattern Zack is using to water his garden, this way:
First week = 1 3/8 gallons of water
Second week = 1 3/4 gallons of water = 1 3/8 + 3/8 = 1 6/8 = 1 3/4
Third week = 2 1/8 gallons of water = 1 3/4 + 3/8 = 1 6/8 + 3/8 = 2 1/8
The constant of adding every week is 3/8 gallons, therefore,
Fourth week = 2 1/8 + 3/8 = 2 4/8 = 2 1/2 gallons of water
Fifth week = 2 1/2 + 3/8 = 2 4/8 + 3/8 = 2 7/8 gallons of water
The correct answer is that Zack used 2 7/8 gallons to water his garden on the fifth week.
Following the pattern of increasing water usage by 3/8 gallons each week, Zack will use 2 7/8 gallons of water in the fifth week.
Zack watered his garden with increasing amounts of water over the first three weeks. Since there is a pattern, we can deduce the amount of water he will use in the fifth week by identifying the pattern and then continuing it.
Week 1: 1 3/8 gallonsWeek 2: 1 3/4 gallonsWeek 3: 2 1/8 gallonsObserving the pattern, we see that Zack is increasing the amount of water by 3/8 gallons each week. The progression in gallons is:
Week 1: 1 3/8Week 2: 1 3/8 + 3/8 = 1 3/4Week 3: 1 3/4 + 3/8 = 2 1/8Continuing this pattern:
Week 4: 2 1/8 + 3/8 = 2 1/2Week 5: 2 1/2 + 3/8 = 2 7/8Therefore, Zack will use 2 7/8 gallons of water on the fifth week.

Suppose Tommy walks from his home at (0, 0) to the mall at (0, 8), and then walks to a movie theater at (7, 8). After leaving the theater Tommy walks to the store at (7, 0) before returning home. If each grid square represents one block, how many blocks does he walk?
Answer:
If each grid square represents one block, then the number of box he walked will be 30 blocks.
Step-by-step explanation:
Tommy walks from his home to the mall and then walks to a movie theater.
His home is at (0,0), the mall is at (0,8) and the movie theater is at (7,8).
Now, distance from (0,0) to (0,8) is 8 units and the distance from (0,8) to (7,8) is 7 units.
So, total distance covered is (8 + 7) = 15 units.
After leaving the theater Tommy walks to the store before returning home.
The store is at (7,0).
Now, the distance from (7,8) to (7,0) is 8 units and the distance from (7,0) to (0,0) is 7 units.
So, total distance covered is (8 + 7) = 15 units.
If each grid square represents one block, then the number of the box he walked will be (15 + 15) = 30 blocks. (Answer)
