Using the formula for the area of a rectangle is, A = l×w where l represents the length of the rectangle and w represents its width, the area of a rectangle with the length of 3.5 centimeters and a width of 2.2 centimeters will be 7.7 cm^2.
What is the area of a rectangle?The area of the rectangle can be calculated using the formula,
(A = l×w )
and the l = the length of the rectangle
w = represents the width of the rectangle
Then to calculate the area of the rectangle, we can substitute the values that is been given as :
(A = l×w )

Horizontal stretch and compressionAn horizontal stretch or an horizontal compression happens when a constant is multiplied at the domain of the function, as follows:
g(x) = f(ax).
The definition of stretch or compression depends on the value of the constant a, as follows:
If a > 1, it is a compression by a factor of 1/a.If a < 1, it is a stretch by a factor of 1/a.In this problem, the rule is:
f(x) = g(2x).
Meaning that f(x) is an horizontal compression by a factor of 1/2 of g(x), and then the vertices are given as follows:

The height of the flagpole is 27 feet.
Given,
If two triangles are similar, sides of these triangles will be proportional.
Height of the flagpole = h feet
Shadow castes by the flagpole = 72 feet
Height of the person = 6 feet
Shadow casted by the person = 16 feet
By using the property of similar triangles,
Hence, h/6 = 72/16
h = (6×72)/ 16
h = 27 feet

An inequality in mathematics is a relationship that makes a non-equal comparison between two integers or other mathematical expressions. It is most commonly used to compare the sizes of two numbers on a number line. There are multiple notations used to denote various types of inequalities: The symbol a b indicates that an is smaller than b. The symbol a > b indicates that an is more than b. In either scenario, a and b are not equal. These are characterized as stringent inequalities because an is either strictly less than or strictly bigger than b. Equivalence is not allowed.

Given a rectangular peice of paper
Length = 34 cm
Width = 16 cm
So, the area of the rectangle = 34 x 16 = 544 cm²
Two semicircles cut out of it
The diameter of the circle = d = 16 cm
So, the radius of the circle = r = d/2 = 8 cm
The area of the two semicircles = area of the complete circle
so, the area of the circle = πr² = 3.14 x 8² = 200.96 cm²
So, the area of the remaining paper = area of the rectangle - area of the circle
= 544 - 200.96 = 343.04 cm²
So, the answer will be Area = 343.04 cm²

A bag contains 3 red, 4blue, 4 yellow, and 5 green marbles only yellow marbles will be added tp the bag. how many yellow marbles should be added to the bag to make the probability of choosing yellow marble 1/3?
Two yellow marbles are added to the bag to make the probability of choosing a yellow marble 1/3 .
There is a bag containing five green marbles, three red marbles, and four blue marbles and four yellow marbles.
The probability that a given event will happen is expressed as a number between 0 and 1 where 0 means there is no chance of the event occurring and 1 means that the outcome is certain.
There are a total of 16 marbles in the bag (5 + 3+ 4+4 = 16). This means that the probability of drawing a marble of a particular color is the number of marbles of that color divided by the total number of marbles in the bag.
Let ‘x’ number of additional yellow marbles be added to the bag.
Then, the required probability will be
(4 + x )/ (16+x ) = 1/3
=> 3(4+x) =16 +x
=> 12+3x = 16+x
=> 2x =4
=> x= 2
Hence, the required number of marbles is 2.

Can someone please help solve the attached :) it's on simultaneous equations combined with congruent triangles
Answer:
2a + b = 180
a + b = 118
a = 64, b = 56
Step-by-step explanation:
If you look at the triangle on the top right of the diagonal, there are 3 angles a, a and b. Since the 3 angles of a triangle add up to 180°
a + a + b = 180
=> 2a + b = 180.......(1)
We are given that the largest angle is 118°
The largest angle of the parallelogram is a + b. Remember that opposite angles of a parallelogram are equal and the sum of the angles add up to 360
Therefore a + b = 118 ....(2)
Given equations (1) and (2), subtract (1) from (2):
Eq (1) - Eq(2) :
2a + b - (a + b) = 180 - 118
a = 62
Substitute for a in equation (2) to get
a + b = 118
62 + b = 118
b = 118 - 62 = 56
So the two angles are a = 64° and b = 56°
Answer:
a = 62, b = 56
Step-by-step explanation:
given the largest angle is 118° , then
a + b = 118 ( subtract b from both sides )
a = 118 - b → (1)
the sum of the interior angles of a quadrilateral = 360°
the angle adjacent to a is b ( alternate angles ) , then
a + b + a + a + b + a = 360
4a + 2b = 360 → (2)
substitute a = 118 - b into (2)
4(118 - b) + 2b = 360
472 - 4b + 2b = 360
472 - 2b = 360 ( subtract 472 from both sides )
- 2b = - 112 ( divide both sides by - 2 )
b = 56
substitute b = 56 into (1)
a = 118 - 56 = 62
a = 62 and b = 56
quick Sarah is walking diagonally across a park as modeled by the equation y = x − 1. Suppose Marcus starts walking at the point (0, 9) so his path is perpendicular to Sarah's. At what point will Sarah's path and Marcus's path intersect?
The Sarah's path and Marcus path will intersect at the point (5,4) .
In the question ,
it is given that
the park is modeled by the equation y = x − 1 .
On comparing with the slope intercept form ,
we get
the slope as 1 .
Since both the paths are perpendicular ,
the slope for Marcus path is -1 .
hence the equation of line with slope -1 and passing through the point (0,9) is y = (-1)x + c
9 = (-1)0 + c
9 = c
so equation is y = (-1)x + 9
So to find the point of intersection , we solve both the equations .
Substituting y = x − 1 in y = (-1)x + 9 ,
we get
x − 1 = (-1)x + 9
x - 1 = -x + 9
x + x = 9 + 1
2x = 10
x = 5
So, y = 5 - 1 = 4
the point of intersection is (5,4) .
Therefore , The Sarah's path and Marcus path will intersect at the point (5,4) .
