The shaded shape is made by joining a square and a rhombus.
Find the area of the shaded shape.
To find area of first figure:
[tex] \\ [/tex]
As it is given in question shaded shape is made by joining a square and a rhombus. It is clearly visible that the first figure is square.
[tex] \\ [/tex]
So to find Area of a Square:-
We know :-
Area of square = side²
[tex] \\ [/tex]
So:-
[tex] \\ [/tex]
⇢ Area of square = side²
[tex] \\ [/tex]
⇢ Area of square = side × side
[tex] \\ [/tex]
⇢ Area of square = 5 × 5
[tex] \\ [/tex]
⇢ Area of square = 25 cm²
[tex] \\ [/tex]
Therefore Area of first figure is equal to 25 cm²
[tex] \\ [/tex]
To find area of second figure:
[tex] \\ [/tex]
So we have find area of square and now as in question given next shape is rhombus.
[tex] \\ [/tex]
There are two Formulas of rhombus :
Area of rhombus = (Digonal 1 × Diagonal 2)/2Area of rhombus = Base × Height[tex] \\ [/tex]
We have to use second formula as Digonals aren't given :
⇢ Area of rhombus = Base × Height
[tex] \\ [/tex]
⇢Area of rhombus = 4.5 × 5
[tex] \\ [/tex]
⇢Area of rhombus = (45 × 5)/10
[tex] \\ [/tex]
⇢Area of rhombus = (45 × 1)/2
[tex] \\ [/tex]
⇢ Area of rhombus = 45/2
[tex] \\ [/tex]
⇢ Area of rhombus = 22.5 cm²
[tex] \\ [/tex]
Therefore Area of first figure is equal to 22.5 cm²
[tex] \\ [/tex]
Area of whole shaded figure:
⇢A = Area of first figure + Area of second figure
[tex] \\ [/tex]
⇢ A = 25 + 22.5
[tex] \\ [/tex]
⇢ A = 47.5 cm²
[tex] \\ [/tex]
Therefore Area of whole shaded figure is equal to 47.5 cm².

A ratio shows us the number of times a number contains another number. The ratio of DE to EF is 3:2. The ratio of DE to EF is 3:1.
What is a Ratio?A ratio shows us the number of times a number contains another number.
1.)
DE = √(6² + 3²)
= √45
= 3√5
EF = √(4² + 2²)
= √20
= 2√5
Ratio = 3√5 / 2√5 = 3/2
Hence, the ratio of DE to EF is 3:2.
2.)
PQ = √(6² + 3²)
= √45
= 3√5
QR = √(1² + 2²)
= √5
Ratio = 3√5/√5 = 3:1
Hence, the ratio of DE to EF is 3:1.

What scale factor was used to create the dilated Triangle M'S'V?
In your answer, give the scale factor that was used and explain how you
calculated it.
The scale factor used to create the dilated Triangle M'S'V is 2/3.
TransformationTransformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.
Dilation is the increase or decrease in the size of a figure by a factor k. If k > 1, it is an increment whereas if k < 1, it is a decrease.
Triangle MSV has vertex at M(-3, 3) while that of M'S'V' has vertex at M'(-2, 2). Hence the scale factor is 2/3

y = 50 {Opposite angles are congruent}x = 30 {Consecutive angles are supplementary}What is a parallelogram?In Euclidean geometry, a parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure
Given is a parallelogram ABCD.
Now, we can state that -
∠A = ∠C
(y + 10) = (2y - 40)
y + 10 = 2y - 40
y = 50
{Opposite angles are congruent}
(4x) + (2y - 40) = 180
4x = 180 - 60
4x = 120
x = 30
{Consecutive angles are supplementary}
Therefore, we can conclude that -
y = 50 {Opposite angles are congruent}x = 30 {Consecutive angles are supplementary}To solve more questions on triangles and parallelogram, visit the link below -

Function represent relationship between variables. The value of f[g(x)] when f(x) = 7x+13 and g(x) = x+2 is 7x+27.
What is Function?A function assigns the value of each element of one set to the other specific element of another set.
Given to us
f(x) = 7x+13
g(x) = x+2
In order to find the value of f[g(x)], we will substitute the value of g(x) at the place of x in f(x).
[tex]f[g(x)] = 7(x+2)+13 \\\\ f[g(x)] = 7x+14+13 \\\\ f[g(x)] = 7x + 27[/tex]

Can you solve (x-2)(x+3) = 5 by solving x - 2 =5 and x + 3 =5? Why or why not?
Answer:
no we cannot because when we solve x-2=5 it gives x=7 and x+3=5 gives x=2 if we place the x value as 7 then it does not justify (x-2)(x+3)=5, if we put x= 2 then again it does not justifies (x-2)(x+3)=5
Step-by-step explanation:
x-2=5
x=5+2
x=7
x+3=5
x=5-3=2
putting x=7 in given equation
(7-2)(7+3) is not equal to 5
putting x=2 in given equation
(2-2)(2+3) is not equal to 5

What are fractions?
We are told that the box of pancake mix has 6 cups.
Now, Eliza uses 3/4 of a cup for a recipe.
Since there are 6 cups in the box, it means the fraction of the box of pancake that Eliza used is;

What is Percentage?A percentage is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
As it is given that the monthly salary of Charlene is $3,410. While her net income is 7% of her monthly income. Therefore, the net income of the Charlene is
[tex]7\%\ of\ \$3410 = \text{Charlene Net income}\\\\\dfrac{7}{100} \times 3410 = \text{Charlene Net income}\\\\ \text{Charlene Net income} = \$238.7[/tex]
Thus, Charlene's net income is $238.7.
Now since Charlene is going to reduce her net income by $125 each month, therefore,
Charlene New Net Income = Charlene Net Income - $125
= $238.7 - $125

The perimeter of a book is 70cm. Its length is 20cm. What is the width?
The perimeter of an object is the sum of all sides.
a book is a rectangle which has 4 sides. 2 sides would be the length and 2 sides would be the width.
Set up the equation:
70 = 20 + 20 + x + x
Simplify
70 = 40 + 2x
Subtract 40 from both sides
30 = 2x
Divide both sides by 2
X = 15
The width of the book is 15 cm

Suppose a city with population 800,000 has been growing at a rate of 5% per year. If this rate continues, find the population of this city in 22 years
Answer:
2,340,208.5 or 2,340,209
Step-by-step explanation:
You could answer this by multiplying the current population of 800,000 by 1.05 (1.05 represents the annual growth rate of population) and do that 22 times. But that would take a while.
we got 1.05 because the formula says that y = a( 1 + r ) power t
for a we will give it 1
so y = 1 ( 1 + 0.05) power t
it will give us 1.05
to do this faster, you would first calculate (1.05)22and then multiply this by 800,000.
So, 800,000 x (1.05)22 = 2,340,208.5 or 2,340,209
