The measure of the angle m∠J is 35°.
An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located.
Consider the triangle KJL,
The line KM is perpendicular to the line JL and M is the midpoint of the line JL.
Therefore, the angle KMJ will be equal to 90°.
Now, we have the angle KJM is equal to 55°.
We know the sum of all interior angles of a triangle is 180°.
So,
In triangle JKM,
∠JKM + ∠KJM + ∠KMJ = 180°
∠JKM + 55° + 90° = 180°
Subtracting 90° from each side of the equation.
∠JKM + 55° + 90° - 90° = 180° - 90°
∠JKM + 55° = 90°
Subtracting 55° from each side of the equation.
∠JKM + 55° - 55° = 90° - 55°
∠JKM = 35°

if there is a matrix, which is 3x8, and 3 columns are linear dependent, then can it be full rank? if not, what rank is it?
The matrix 3 x 8 is a full rank matrix.
Matrix:
Matrix are a set of numbers arranged in rows and columns so as to form a rectangular array. The numbers are called the elements, or entries, of the matrix.
Full rank matrix:
The rank of a matrix is the maximum number of its linearly independent rows.
Based on that, A full rank matrix is one which has linearly independent rows or/and linearly independent columns.
Given,
There is a matrix, which is 3x8, and 3 columns are linear dependent
Her we need to check whether the matrix is full rank or not.
We know that, the matrix is 3 x 8,
And 3 column are linear dependent,
Based on the following condition,
An m×n matrix with m<n , then it has full rank when its m are linearly independent.
So, the given matrix 3 x 8 is the full rank matrix.

x = -4.36364
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define Equation
3.5(x + 12) = -2x + 18
Step 2: Solve for x
Distribute 3.5: 3.5x + 42 = -2x + 18Add 2x on both sides: 5.5x + 42 = 18Isolate x term: 5.5x = -24Isolate x: x = -4.36364Answer:
The answer I arrived at was x = -4.364
Step-by-step explanation:
3.5(x + 12) = -2x + 18
=> multiply 3.5 by everything in parenthesis
3.5x + 42 = -2x + 18
=> subtract 18 from both sides
3.5x + 24 = -2x
=> subtract 3.5x from both sides
24 = -5.5x
=> divide both sides by -5.5
-4.364 = x

Jackie went to the store and bought 2 1/4 pounds of apples at $5 per pound and 9 pounds of pears at $2.35 per pound. If she paid with a $50 bill, how much change did she receive? Hint* USE THE $ SIGN IN YOUR ANSWER. YOUR ANSWER SHOULD HAVE 2 DECIMAL PLACES.
Answer:
$17.60
Step-by-step explanation:
Jackie went to the store and bought 2 1/4 pounds of apples at $5 per pound
1 pounds = $5
2 1/4 pounds = x
x = 2 1/4 × $5
x = 9/4 × $5
x = $45/4
x = $11.25
9 pounds of pears at $2.35 per pound.
1 pound = $2.35
9 pounds = x
x = 9 × $2.35
x = $21.15
Total amount that she spent =
$11.25 + $21.15
= $32.40
If she paid with a $50 bill, how much change did she receive?
The change she received =
$50 - $32.40
= $17.60

The circumference of a circle is 17π ft. What is the area, in square feet? Express your answer in terms of \piπ.
The answer for this question is 72.25pi
The area of the circle is 72.25π ft².
What is Surface Area?For each three-dimensional geometrical shape, surface area and volume are determined. The area or region that an object's surface occupies is known as its surface area. Volume, on the other hand, refers to how much room an object has.
As per the given data:
circumference of a circle = 17π ft
To find the area of the square:
Area = πR²
For radius (R):
2πR = 17π
R = (17/2) ft
Area = π(17/2)²
= 72.25π ft²
Hence, the area of the circle is 72.25π ft².
