Answer:
11.8
Step-by-step explanation:
The solution is 11.0 < 4x + 3 < 12.0
The inequality equation is 11.0 < 4x + 3 < 12.0 , where the value of the equation 4x + 3 = 11.8 , when x = 2.2
What is an Inequality Equation?
Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the equation is P = 4x + 3
The value of x = 2.2
Correcting the value of x to one decimal place , we get x = 2.2
Substitute the value of x in the equation , we get
P = 4x + 3
when x = 2.2
P = 4 ( 2.2 ) + 3
P = 8.8 + 3
P = 11.8
Now , the inequality equation is 11.0 < 11.8 < 12.0
Hence , the inequality equation is 11.0 < 4x + 3 < 12.0 , where 4x + 3 = 11.8

The circumference of a cirlcle is 125.6 ft. What os the area?
Find the perimeter and area of the polygon shown below.
Answer:
I'm sorry. I cannot explicitly give you an answer. The picture of the polygon is not provided. You may have forgotten to upload it, nevertheless, I''ll try my best to be of help to you.
Step-by-step explanation:
There are many different polygons. But the general formula to finding the perimeter of a polygon is:
P = n * l
n = number of sides
l= value shared and assigned to each side
The general formula to finding the area of a regular polygon is:
A = (n*l*apothem )/2
n = number of sides
l = length of one side
apothem = the value of the segment connecting the center of the polygon to a midpoint of one of the sides.

The sum of four consecutive odd integers is 328. What are the integers? show your work please
Step-by-step explanation:
For a formal algebraic solution, you might do something like this....
x = 1st integer
x+2 = 2nd
x+4 = 3rd
x+6 = 4th
The sum is 328:
Then solve that equation to find x and thus find the solution to the problem.
Or, if formal algebra is not required (and you want to get the answer as fast as possible)....
The average of the four integers is 328/4 = 82; the four integers are the two odd integers either side of 82 and closest to 82 -- 79, 81, 83, and 85.
The required consecutive odd integers are 79, 81, 83, and 85 whose sum is 328.
Given that,
The sum of four consecutive odd integers is 328. What are the integers is to be determined?
A number system is represented as a process of writing to represent digits. It is the mathematical inscription for describing numbers of a given set by using numbers or other characters in a uniform method. It delivers a special presentation of every digit and describes the arithmetic structure.
Here,
let the consecutive odd number be
2n + 1 , 2n +3, 2n + 5, 2n + 7
Whose sum is 328. So,
2n +1 + 2n + 3 + 2n + 5 + 2n +7 = 328
8n + 16 = 328
8n = 312
n = 39
Now,
2n + 1 = 39 * 2 + 1 = 79
Similarly
2n +3 = 81
2n + 5 = 83
2n + 7 = 85
Thus, the required consecutive odd integers are 79, 81, 83, and 85 whose sum is 328.

given that q is directly proportional to (p-1)square and p is always positive find the value of p when a=20, if q=4 when p=10
Answer:
1 + 9√5
Step-by-step explanation:
q = (p-1)² * k
4 = (10-1)² * k
k = 4/81
q=20 20 = (p-1)² * 4/81
(p-1)² = 20 * 81/4 = 405

View picture for full equation:) please and thank you!
Answer:
60°
Step-by-step explanation:
There is a supplementary angle, so we know that 180°-100° would give 80°.
A triangles angles add up to 180, so 80+40=120
180-120=60°
Answer:
60 degrees
Step-by-step explanation:
Hi there!
Angle NAB and angle CAB are supplementary angles, meaning they add up to 180 degrees. First, solve for angle CAB:
180 - 100 = 80
Therefore, angle CAB measures 80 degrees.
The sum of the interior angles of a triangle is always 180 degrees. Now, we can solve for angle B by subtracting 80 and 40 from 180:
180 - 80 - 40 = 60
Therefore, angle B measures 60 degrees.
Another way we can solve this is by viewing the 100-degree angle as an exterior angle of a triangle. The two opposite interior angles always add up to an exterior angle of a triangle.
100 = 40 + 60
Therefore, angle B measures 60 degrees.
I hope this helps!

The distributive works for multiplication and addition. You switch the order of the problem but it doesn't change the final product or sum.
Answer:
Is there a question?
Step-by-step explanation:
If it is, by the way I look at it, To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.
Determine whether the lines AB and CD would be parallel, perpendicular, or neither?
A(-5,3) and B(-5, 7)
WILL GIVE BRAINLIEST
What is the slope of AB?
C(1, 9) and D(-10, 9)
What is the slope of CD?
What are the lines? (parallel, perpendicular or neither)
Answer:
Slope of AB is undefined; slope of CD is 0; the lines are perpendicular.
Step-by-step explanation:
Slope (M) can be found with the equation M=y2-y1/x2-x1, or change in y over change in x. In this equation, finding the slope is very easily done without even using the equation, because it can be seen in AB that the x value doesn't change (showing a vertical line), and in CD the y value doesn't change (showing a horizontal value). When they intercept, they make a cross-shape, so they are perpendicular.

Nellie has a bankruptcy on her credit report and therefore pays higher interest rates on her current loans. She took out a car loan for $45,000 payable for 6 years at an interest rate of 15%. If she had not applied for bankruptcy, she would have been able to take out the loan at a rate of 6%. Approximately how much more in interest over the life of the loan does Nellie have to pay?
a. $68,510.16
b. $53,696.16
c. $32,206.32
d. $14,814.00
The amount of extra interest that will be paid is $24300
Since Nellie took out a car loan for $45,000 payable for 6 years at an interest rate of 15%, the interest that she will pay will be:
= ($45000 × 6 × 15) / 100
= $40500
On the other hand, if she hasn't applied for bankruptcy, the amount that she will pay will be:
= ($45000 × 6 × 6) / 100
= $16200
Therefore, the difference between the interest will be:
= $40500 - $16200
= $24300
The correct option is $24300. The given options are incorrect.
