Find the area, in square inches, of the composite figure.
A composite figure consisting of an isosceles right triangle, a rectangle, and an another isosceles triangle. The combined length of the right triangle and the rectangle is 25 inches. The length of only the rectangle is 14 inches. The base of the other isosceles triangle, which is the same as the width of the rectangle, is 2 inches plus 2 inches, and the height of the isosceles triangle is 3 inches.
The area of the composite figure is 122.5 square inches
How to find the area of the composite figure.Based on the problem statement, we have the following dimensions from the question
Isosceles right triangle: 11 inchesRectangle: 14 inches by 4 inchesAnother isosceles triangle; Base = 4 inches and Height = 3 inchsThe area of the composite figure is the sum of individual areas
So, we have
Area = Isosceles right triangle + Rectangle + Another isosceles triangle
By applying the formulas, we have
Area = 0.5 * 11 * 11 + 14 * 4 + 0.5 * 4 * 3
Evaluate
Area = 122.5
Hence the area is 122.5 sq inches

3/4 of girls in sss1 play basketball and 4/7 play volleyball. Every girl plays at least one of these games. if 27 play both games how many girls are in the class
Answer:
84
Step-by-step explanation:
1/4 of class don't play basketball but do play volleyball
so 9/28 of class play both since 4/7 - 1/4 = 9/28
9/28 of class = 27
1/28 of class = 3
class = 3*28
There are 84 girls in the class.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Girls who plays basketball = (3/4)x
Girls who plays volleyball = (4/7)x
Girls who plays both games = 27
Now, Let us consider total girls in the class = x
So we can write it as mathematical equation as;
⇒ (3/4)x +(4/7)x - 27 = x
By taking L.C.M. -
⇒ (21x+16x)/28 - (27) = x
⇒ 37x/28 = x + 27
⇒ 37x = 28x + (27×28)
⇒ 9x = 27×28
⇒ x = (27×28)/9
⇒ x = 3×28
⇒ x = 84
So, There are total 84 girls in the class.

Determine the value of h such that the matrix is the augmented matrix of a consistent linear system.[1 h 43 6 8]
The value of h such that the matrix is the augmented matrix of a consistent linear system is 2
For the given matrix to be the augmented matrix of a consistent linear system, we need to check whether the matrix is in row echelon form or not. If the matrix is in row echelon form and the last row is not all zeros, then the linear system is consistent.
We can use elementary row operations to transform the matrix into row echelon form.
\(\left[\begin{array}{ccc}1&h&4\\3&6&8\end{array}\right]\)
R2 <- R2 - 3R1
\(\left[\begin{array}{ccc}1&h&4\\0&6-3h&-4\end{array}\right]\)
The matrix is in row echelon form. Now, we need to check whether the last row is all zeros or not.
If 6-3h = 0, then the last row will be all zeros, which implies that the linear system is inconsistent.
If 6-3h ≠ 0, then the last row will not be all zeros, which implies that the linear system is consistent.
Therefore, we need to solve the equation 6-3h = 0 to determine the value of h that makes the linear system consistent.
6-3h = 0
3h = 6
h = 2
So, the value of h that makes the matrix the augmented matrix of a consistent linear system is h = 2.

Hence the equation for the theorem is given as follows:
c² = a² + b².
In which:
c > a and c > b is the length of the hypotenuse.a and b are the lengths of the other two sides (the legs) of the right-angled triangle.For the triangle in this problem, we have that:
The sides are d ft and 90 ft.The hypotenuse is of 409 ft.Hence the distance is obtained as follows:

the perimeter of a triangle is 32 feet. One side of the triangle is 11 feet longer than the second side. The third side is 9 feet longer than the second side. Find the length of each side.
Answer:
One side - 15 feet
Second side - 4 feet
Third side - 13 feet
Step-by-step explanation:
Let's call the sides A B and C, respectively.
We know that:
A = B + 11
C = B + 9
and that
A + B + C = 32
Please note that we have 3 equations and 3 unknowns. We can solve this, we'll use substitution.
A + B + C = (B + 11) + B + (B + 9) = 32
3B + 20 = 32
3B = 12
B = 4
The sides have lengths of 4+11 = 15, 4 and 4+9 = 13. This is in fact a proper triangle (because the shorter sides add up to more than the longer side).
Can Defects A company that makes soda pop cans finds that the
probability of producing a can without a puncture is 0.96, the probability that
a can does not have a smashed edge is 0.93, and the probability that a can
does not have a puncture and does not have a smashed edge is 0.893.
(a) Are the events "selecting a can without a puncture" and "selecting a can
without a smashed edge" mutually exclusive? Explain.
(b) If a quality inspector randomly selects a can, find the probability that the
can does not have a puncture or does not have a smashed edge
Using probability concepts, it is found that:
a) Since \(P(A)P(B) \neq 0\), the events are not mutually exclusive.
b) 0.997 = 99.7% probability that the can does not have a puncture or does not have a smashed edge.
Item a:
Two events, A and B, are mutually exclusive if:
\(P(A \cap B) = 0\)
In this problem:
Event A: No puncture, thus, \(P(A) = 0.96\).Event B: No smashed edges, thus \(P(B) = 0.93\)The problem also states that the probability of neither is \(P(A \cap B) = 0.893\).
Since \(P(A)P(B) \neq 0\), the events are not mutually exclusive.
Item b:
Using Venn probabilities, the "or" probability is given by:
\(P(A \cup B) = P(A) + P(B) - P(A \cap B)\)
With the given values:
\(P(A \cup B) = 0.96 + 0.93 - 0.893 = 0.997\)
0.997 = 99.7% probability that the can does not have a puncture or does not have a smashed edge.

Could be: Square.
b. My quadrilateral has two sets of parallel sides.
Must be: Parallelogram.
Could be: Rectangle, Rhombus, Square
c. My quadrilateral has four right angles.
Must be: Rectangle.
Could be: Square.
Explanation:
a. A quadrilateral with four equal sides must be a rhombus. It could also be a square, but a square is a special type of rhombus, so a rhombus is the "must be" shape.b. A quadrilateral with two sets of parallel sides must be a parallelogram. It could also be a rectangle, a rhombus, or a square. However, a rectangle, rhombus, or square is also a parallelogram, so a parallelogram is the "must be" shape.
c. A quadrilateral with four right angles must be a rectangle. It could also be a square, but a square is a special type of rectangle, so a rectangle is the "must be" shape.
Answer:
a) Must be a rhombus.
Could be a square, a rectangle, a parallelogram, a trapezoid, or a kite.
b) Must be a parallelogram.
Could be a square, a rectangle, a kite, or a rhombus.
c) Must be a rectangle.
Could be a square, a kite, a rhombus or a parallelogram.
Step-by-step explanation:
The six basic types of quadrilaterals are:
Square: All interior angles are 90°. Side lengths are equal.Rectangle: All interior angles are 90°. Opposite sides lengths are equal.Rhombus: Side lengths are equal.Trapezoid: One pair of parallel sides.Parallelogram: Opposite sides are parallel.Kite: Two pairs of equal length sides (these sides are adjacent to each other).a) "My quadrilateral has four equal sides"A quadrilateral by definition is a four-sided shape. Therefore, it is possible for all types of quadrilateral to have four equal sides. However, for it to be a square and a rhombus, it must have four equal sides.
The interior angles of a square are all right angles, and its opposite sides are parallel. So as we haven't been told anything about the interior angles of the quadrilateral, or if any of its sides are parallel, we can conclude that:
The quadrilateral must be a rhombus.The quadrilateral could be a square, a rectangle, a parallelogram, a trapezoid, or a kite.b) "My quadrilateral has two sets of parallel sides"The types of quadrilateral that can have two sets of parallel sides are square, rectangle, rhombus, parallelogram and kite (all squares are kites).
The interior angles of a square and a rectangle are 90°.
The side lengths of a rhombus are congruent.
As we haven't been told anything about the interior angles or the side lengths of the quadrilateral, we can conclude that:
The quadrilateral must be a parallelogram.The quadrilateral could be a square, a rectangle, a kite, or a rhombus.c) "My quadrilateral has four right angles"All quadrilaterals, apart from a trapezium, can have interior angles that are all right angles. However, for a quadrilateral to be a square or a rectangle, it must have interior angles that are right angles.
As we don't know if the side lengths of the quadrilateral are equal, we cannot know if it's a square. Therefore, we can conclude that:
The quadrilateral must be a rectangle.The quadrilateral could be a square, a kite, a rhombus or a parallelogram.what is the area of the shaded area. Round to the nearest whole unit.
