If the perimeter of the
rectangle is 36 inches,
what is the value of x?
X-3
7x+5
Answer:
x = 2
Step-by-step explanation:
To find the value of x, we simply need to use the know values for the lengths, widths, and perimeter of the rectangle.
The formula for the perimeter of a rectangle is as follows:
P = 2L + 2W
Where P is the perimeter, L is the length, and W is the width.
Let L = 7x + 5 and W = x - 3
Now, we will simply plug our values into the formula and solve for x.
P = 2L + 2W
36 = 2 ( 7x + 5 ) + 2 ( x - 3 )
36 = 14x + 10 + 2x + -6
36 = 16x + 4
32 = 16x
2 = x
Thus, we have found the value of x to be 2.
Cheers.

The identification code on a bank card consists of 1 digit followed by 2 letters. The code must meet the following conditions: The digit must be odd. The letters A, E, I, O, and U cannot be used. Letters cannot be used more than once.
Answer:
For the code we have 3 selections.
The first selection is a digit that must be odd, so the options are {1, 3, 5, 7 ,9}
So we have 5 options.
The second selection is a letter from the set of all the letters (27) minus the set of the vowels (5)
So here we have 27 - 5 = 22 options
The third selection is also a letter from the previous set, but because each letter can be used only one time, and in the previous selection we already selected one of the letters, in this selection we have a letter less than in the previous selection.
Here we have 22 - 1 = 21 options.
The total number of combinations (of possible codes) is equal to the product of the number of options for each selection:
C = 5*22*21 = 2310.
There are 2310 different possible codes
x^2+y^2=25 Y= 2x - 5
What are the x coordinates
Answer:
(0, -5) and (4, 3)
Step-by-step explanation:
I assume you're looking for the coordinates of the intersections, if any.
Solve by substitution:
x² + (2x − 5)² = 25
x² + 4x² − 20x + 25 = 25
5x² − 20x = 0
5x (x − 4) = 0
x = 0 or 4
So the coordinates are (0, -5) and (4, 3).
Solve for x. 3(2x - 2) = 21 + 3x
15 5 20 9
Answer:
x=9
Step-by-step explanation:
3(2x - 2) = 21 + 3x
Divide each side by 3
3/3(2x - 2) = 21/3 + 3x/3
2x-2 = 7+x
Subtract x from each side
2x-2-x = 7+x-x
x-2 = 7
Add 2 to each side
x-2+2 = 7+2
x = 9
In a manufactory, there are two types of spoilages. It is found that 5% of spoilages are due to transformer spoilage, 8% are due to line spoilage and 3% involve both problems. (a) Are the two types of spoilages independent or not? Justify your answer. (b) What is the probability that: i- line spoilage given that there is transformer spoilage ii- Transformer spoilage but not line spoilage. iii- Transformer spoilage given that there is no line spoilage iv- Neither transformer spoilage nor there is no line spoilage v- Either transformer spoilage or there is no line spoilage
Answer:
Step-by-step explanation:
Let us denote probability of spoilage as follows
Transformer spoilage = P( T ) ; line spoilage P ( L )
Both P ( T ∩ L ) .
Given
P( T ) = .05
P ( L ) = .08
P ( T ∩ L ) = .03
a )
For independent events
P ( T ∩ L ) = P( T ) x P ( L )
But .03 ≠ .05 x .08
So they are not independent of each other .
b )
i )
Probability of line spoilage given that there is transformer spoilage
P L/ T ) = P ( T ∩ L ) / P( T )
= .03 / .05
= 3 / 5 .
ii )
Probability of transformer spoilage but not line spoilage.
P( T ) - P ( T ∩ L )
.05 - .03
= .02
iii )Probability of transformer spoilage given that there is no line spoilage
[ P( T ) - P ( T ∩ L ) ] / 1 - P ( L )
= .02 / 1 - .08
= .02 / .92
= 1 / 49.
i v )
Neither transformer spoilage nor there is no line spoilage
= 1 - P ( T ∪ L )
1 - [ P( T ) + P ( L ) - P ( T ∩ L ]
= 1 - ( .05 + .08 - .03 )
= 0 .9

Find the standard form of the equation of the ellipse with the given characteristics. Center: (1, 2); vertex: (−7, 2); minor axis of length 12
Answer:
(x-1)²/64 + (y-2)²/144 = 1
Step-by-step explanation:
The standard equation of an ellipse is expressed as (x-h)²/a² + (y-k)²/b² = 1
Where the coordinate (h,k) is the centre of the ellipse.
a is the the difference of the x coordinates of the centre and the vertex.
b is the minor axis.
Given the centre to be (1,2), on comparing with the coordinate (h,k),
h = 1 and k = 2
The difference of the x coordinates of the centre and the vertex = -7-1 = -8
The minor axis as given in the equation is b = 12
Substituting the given parameters into the equation of an ellipse above we will have;
(x-1)²/(-8)² + (y-2)²/12² = 1
(x-1)²/64 + (y-2)²/144 = 1
The final equation gives the required standard form of the equation of the ellipse.

Ms. Rangtonsmith make $25 dollars an hour. Her boss will be giving him a raise that is 1/5 of her current salary. How much money will Ms. Rangtonsmith be making AFTER he gets a raise?
Answer:
Ms. Rangtonsmith will get $30 after raise
Step-by-step explanation:
Current salary = $25
raise = 1/5 of current salary
substituting current salary with $25
raise in dollar value = 1/5 of $25 = 1/5 *$25 = $5
Thus, raise is $5
total salary after raise will be sum of current salary and raise
total salary after raise = $25 + $5 = $30
Thus, Ms. Rangtonsmith will get $30 after raise
1. 25p=100 2. 35=-2x-15
• Answer:
p = 4
x = - 25
• Step-by-step explanation:
25p = 100
p = 100÷25
p = 4
35 = - 2x - 15
2x = - 35 - 15
2x = - 50
x = - 25
Answer:
1) P= 4 2) x = -25
Step-by-step explanation:
25p = 100
divide both sides by 25
p = 4
35 = -2x - 15
add 15 to both sides
50 = -2x

solve for h
can someone please answer and explain thank you <33
Answer: [tex]h=\frac{2A}{(a+b)}[/tex]
Step-by-step explanation:
To solve for h, we want to get h alone. We need to use our algebraic properties.
[tex]A=\frac{1}{2} h(a+b)[/tex] [multiply both sides by 2]
[tex]2A=h(a+b)[/tex] [divide both sides by (a+b)]
[tex]h=\frac{2A}{(a+b)}[/tex]
Now that we have h alone, we know that [tex]h=\frac{2A}{(a+b)}[/tex].
WILL MARK BRAINLIEST An architect is drafting a scale drawing of a house for an upcoming project. The customer wants the front of the house to measure 60 feet long. The architect's sketch shows that the front of the house has a length of 15 inches. Determine the factor of dilation used by the architect as he created the scale drawing for his customer. In your final answer, include all of your calculations.
Answer:
The scale factor is 1/48
Step-by-step explanation:
First, we need to convert 60 feet to inches.
60 feet = 720 inches
Then, we divide 720 by 15
720/15= 48.
The scale factor is 1/48.
The scale factor of dilation is given by the proportion and A = 48
What is Proportion?The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the proportion be represented as A
Now , the value of A is
We can use the ratio of the lengths of the corresponding sides to find the scale factor or dilation factor used by the architect.
Let A be the factor of dilation used by the architect. Then we can set up the following proportion:
60 feet / A = 15 inches / 1
We can solve for x by cross-multiplying:
60 feet x 1 = A x 15 inches
A = (60 feet) / (15 inches)
We need to convert feet to inches to get the units to match:
A = (60 feet) / (15 inches) x (12 inches / 1 foot)
Simplifying, we get:
A = 720 / 15
A = 48
Hence , the architect used a scale factor of 48 when creating the scale drawing of the house
