The width of a rectangle is 2 inches smaller than its length. The perimeter is 24 inches. Find the length and width of the rectangle.
Answer:
7 inches and 5 inches
Step-by-step explanation:
The length the length and width of the rectangle be l and b.
Accodrding to question,
Width, b = l-2
Perimeter, P = 24 inches
We know that,
The perimeter of a rectangle is given by :
P = 2(l+b)
24 = 2(l+l-2)
12 = 2l-2
14=2l
l = 7 inches
Width, b = 7-2 = 5 inches
Hence, the length and width of the rectangle are 7 inches and 5 inches respectively.
The perimeter of a rectangle is 260 yards. The length is 30 yards greater than the width. Find the dimensions of the rectangle.
Answer:
width: 50 yards
length: 80 yards
Step-by-step explanation:
I would write an equation to start
x = width
260 = 2x + 2(x + 30)
260 = 4x + 60
200 = 4x
x = 50
Width = 50 yards
Length = width + 30
Length = 50 + 30
Length = 80 yards
All of the following could be rewritten as an addition problem of two integers with the same sign except _____.
-9 - (-12)
-9 - 12
-12 - 9
12 - (-9)
Answer:
Answer is - 9 + 12 because they have different signs in front of each integer. (if that is what the question means)
Step-by-step explanation:
Negative sign x negative sign = positive sign
-9 - (-12) = -9 + 12
-9 - 12
-12 - 9 = -9 - 12
12 - (-9) = 12 + 9 = 9 + 12
Determine m∠DFG :))))
=========================================================
Explanation:
We can apply the remote interior angle theorem.
The exterior angle DFG is far away from the remote interior angles FGH and GHF. In other words, the exterior angle is not adjacent to these remote interior angles.
The remote interior angles add to this exterior angle.
(angle FGH) + (angle GHF) = angle DFG
(89) + (5x-7) = 14x+1
5x + 82 = 14x + 1
82-1 = 14x-5x
81 = 9x
9x = 81
x = 81/9
x = 9
If this is the case, then,
angle DFG = 14*x+1 = 14*9+1 = 127
I dont understand how to do this, looking for someone who can help

Answer:
ABCD is a rhombus => AC is perpendicular with BD
=> AC = 2(2n + 5) = 30
<=> 2n + 5 = 15
=> n = 5
with n = 5 => AC/2 = 15
BD/2 = 4.5 - 3 = 17
BC² = (AC² + BD²)/4 = 514/4 = 128.5
=> BC = 11.34
Answer:
Step-by-step explanation:
The question is what does 2n + 5 represent? Is it 1/2 the line or all of AC. There seems to be a run on ambiguous questions. I'm going to assume that 2n + 5 is AC -- all of it. And 4n-3 is all of BD.
AC = 30
2n + 5 = 30 Subtract 5 from both sides.
2n = 30 - 5
2n = 25 Divide by 2
n = 25/2
n = 13.5
====================
BD = 4n - 3
BD = 4*13.5 - 3
BD = 54 - 3
BD = 51

They are 20 blocks per mile in tara's city. Tara's walks 13 blocks. Her fitness tracker say he walk 0.71 mile. Show if her fitness tracker is accurate.
Answer:
Step-by-step explanation:
13 blocks × (1 mile)/(20 blocks) = 13/20 mile = 0.65 mile
Tracker is inaccurate
The fitness tracker is inaccurate.
What is a Ratio?A ratio indicates the number of times one number contains another.
Given that, there are 20 blocks per mile.
20 blocks = 1 mile
1 block = (1/20) mile
13 block = (13/20) mile
13 block = 0.65 mile
Therefore, Tara walks 0.65 miles, not 0.71 miles.
Hence, the fitness tracker is inaccurate.

Is 16=3 one, no, or many solutions?
And if the lines were graphed, would they be the same line, intersecting, or parallel
Answer:
No solutions; parallel
Step-by-step explanation:
The equations x=16 and x=3 both have a slope of 0. So when graphed, they would be parallel and there are no solutions between parallel lines.
what is angle a and c if b is 63 degrees? You will get 100 points for answering please help
Answer:
Angle A measures 76°
Step-by-step explanation:
The three interior angles of a triangle will always equal 180. Therefore:
[tex](63)+(x+7)+(2x+8)=180[/tex]
Solve for x. Add and combine like terms:
[tex]78+3x=180[/tex]
Subtract 78 from both sides:
[tex]3x=102[/tex]
Divide both sides by 3. So, the value of x is:
[tex]x=34[/tex]
Angle A is given by:
[tex]m\angle A=2x+8[/tex]
Since we know that x = 38:
[tex]m\angle A=2(34)+8=76[/tex]
Angle A measures 76°

The question is incomplete. Here is the complete question.
Mr. Jackson decides to build a planter in the shape of a cube fo rhis wife. The top of the planter will be open so his wife can plant and water her flowers. The perimeter of the bottom of the planter is 12 feet.
How many square feet of material does Mr Jackson need to build the planter?
(a) 27 square feet
(b) 45 square feet
(c) 60 square feet
(d) 720 square feet
Answer: 45 square feet
Step-by-step explanation: A cube is a regular solid with six square faces.
Square is a quadrilateral with 4 right angles and 4 equal sides. So a cube is solid formed by 6 squares.
Perimeter is the sum of all the sides. For a square, perimeter is given by
P = 4s
Then, side of the bottom is
[tex]s=\frac{P}{4}[/tex]
[tex]s=\frac{12}{4}[/tex]
s = 3
Area of a square is
[tex]A=s^{2}[/tex]
[tex]A=3^{2}[/tex]
A = 9
The planter is a cube with 5 faces, because the top is open. Then, total area is
[tex]A_{t}=9+9+9+9+9[/tex]
[tex]A_{t}=[/tex] 45
Mr Jackson will need 45 square feet of material to build the planter.
Answer:

Answer:
12x +12y = 7
Step-by-step explanation:
The 2-point form of the equation for a line is useful.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (1/3 -1/4)/(1/4 -1/3)(x -1/3) +1/4
y = (1/12)/(-1/12)(x -1/3) +1/4)
y = -x +1/3 +1/4
Add x and multiply by 12.
x +y = 1/3 +1/4
12x +12y = 4 +3
12x +12y = 7
Which value of y makes the equation below true?
−4(y+2)−6(y−3)=12
A y=−19/5
B y=−1/5
Cy=−13/10
D -y=−11/5
Answer:
B
Step-by-step explanation:
-4y-8-6y+18=12
-10y=12+8-18
Y=-1/5

The solution is, the previous salary is $40910.
What is division?Division is the process of splitting a number or an amount into equal parts. Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication.
here, we have,
The total salary is $45000
Divide 10% by 100 to express the value as a decimal: 10/100= 0.1
Let x represent the previous salary.
If the previous salary was increased by 10% this means that they calculated the 10% of X and added it to the salary for the increase, symbolically:
x+0.1x=45000
1.1x=45000
x= 45000/1.1
x= 40909.09≅ $40910
Hence, The solution is, the previous salary is $40910.
