Answer:

200

Step-by-step explanation:

11^2+10^2=x^2

121+100=x^2

221=x

nearest 100th would be 200

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

Answer:

Step-by-step explanation:

At Step 2 you subtract 1/2 from both sides of the equation:

Its justification is therefore is:

1/2 x² + x + 3/2 is the correct answer......

Answer:

B) $1.25/ 4

Step-by-step explanation:

if Anna had $5.00 to start with and after buying 4 pencils she had $3.75 left that would mean each pencil was around $1.25.

$5.00 subtract $3.75 equals $1.25

Answer: I THINK ITS (-10/8)

Step-by-step explanation:

Charlene’s new net income will be $113.70.

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

                                              = $113.70

Hence, Charlene’s new net income will be $113.70.

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

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 -

Step-by-step explanation:

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 :

[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.

The fraction of the box of pancake that eliza used is; 1/8.

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;

(3/4)/6 = 3/24 = 1/8

In conclusion, the fraction of the box of pancake that eliza used is 1/8.

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.

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.

The scale factor used to create the dilated Triangle M'S'V is 2/3.

Transformation 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

The scale factor used to create the dilated Triangle M'S'V is 2/3.

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

Function represent relationship between variables. The value of f[g(x)] when f(x) = 7x+13  and g(x) = x+2 is 7x+27.

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]

Hence, the value of f[g(x)] when f(x) = 7x+13 and g(x) = x+2 is 7x+27.
