The area of the rectangle is 3[tex]\sqrt{56}[/tex]

Given,

A rectangle has a length of √7 and a width of 3√8.

We need to find the area of the rectangle.

The area is given by:

Area = Length x width

Find the length and width of a rectangle.

Length = [tex]\sqrt{7}[/tex]

Width = 3[tex]\sqrt{8}[/tex]

Find the area of the rectangle.

Area =  Length x width

       = [tex]\sqrt{7}[/tex] x 3[tex]\sqrt{8}[/tex]

When there are two different square roots we multiply them together under one root.

[tex]\sqrt{a\times b} ~~=~~\sqrt{a}\times\sqrt{b}[/tex]

Now,

       = 3[tex]\sqrt{7\times8}[/tex]

       = 3[tex]\sqrt{56}[/tex]

Thus the area of the rectangle is 3[tex]\sqrt{56}[/tex]

[tex]\tt Step-by-step~explanation:[/tex]

Remember: PEMDAS - Parentheses, exponents, multiply/divide, add/subtract

Distribute: 9(1+x) = 9+9x

19 - 5x = 9 + 9x

Add 5x to both sides of the equation and subtract 9 from both sides.

19 - 5x + (5x) = 9 + 9x + (5x)

19 - (9) = 9 - (9) + 14x

10 = 14x

Divide both sides by 14 to get the variable on its own.

10/14 = 14x/14

10/14=x

5/7 = x

Step-by-step explanation:

Two triangles are congruent if they have the same shape and their corresponding sides are equal to each other.

1) AB = DC, BE = CE     (given)

2) ∠AEB≅∠DEC  (vertical angles are congruent)

3) ΔABE ≅ ΔACE (side angle side congruence theorem)

If the two sides and an included angle of one triangle is equal to two sides and one included angle of another triangle, then the two triangles are congruent by SAS congruence theorem.

Answer:

The equation is 1/3x+2>11

Anything greater than 27 is a possible answer

Step-by-step explanation:

Step 1

Subtract 2 from both sides, 2-2 cancels out and 11-2=9

Now you have 1/3x>9

Step 2

Divide both sides by 1/3, 1/3 divided by 1/3 cancels outs and 9 divided by 1/3 is 27

Now you have x>27

So anything greater than 27 is a possible answer

Answer:

D

Step-by-step explanation:

Using the rules of logarithms

log x - log y = log ([tex]\frac{x}{y}[/tex] )

log [tex]x^{n}[/tex] = nlog x

[tex]log_{b}[/tex] x = n ⇒ x = [tex]b^{n}[/tex]

Given

[tex]log_{3}[/tex] (4x) - 2[tex]log_{3}[/tex] x = 2

[tex]log_{3}[/tex] (4x) - [tex]log_{3}[/tex] x² = 2

[tex]log_{3}[/tex] ([tex]\frac{4x}{x^2}[/tex] ) = 2

[tex]log_{3}[/tex] ([tex]\frac{4}{x}[/tex] ) = 2

[tex]\frac{4}{x}[/tex] = 3² = 9 ( multiply both sides by x )

4 = 9x ( divide both sides by 9 )

[tex]\frac{4}{9}[/tex] = x → D

The prime factorization of 200 is as follows: 200 = 2 × 2 × 2 × 5 × 5.

The prime factorization of 200 will be equal to 2 × 2 × 2 ×  5 × 5 or 2³ × 5².

It is given that a number is 200.

We have to find out the prime factorization of 200.

What do you mean by prime factorization ?

Prime factorization is a way to find the prime factors of a number, such that the original number is evenly divisible by the prime numbers.

As per the question ;

The given number is 200.

We have to find the prime factors of 200.

This meant to find out the prime numbers we should multiply together to make the original number which is 200.

So ;

200

= 2 × 100

= 2 × 2 × 50

= 2 × 2 × 5 × 10

= 2 × 2 × 2 ×  5 × 5

or

= 2³ × 5²

Thus , the prime factorization of 200 will be equal to 2 × 2 × 2 ×  5 × 5 or 2³ × 5².

Answer:

24%

Step-by-step explanation:

Q: Maya has 200 songs on her mobile device. Of these songs, 48 are jazz songs. What percent of Maya's songs are jazz songs?

To find the percentage of something, we can take the number that we want to find the percentage for divided by the total number of items.

In this problem, the number that we want to find the percentage for are the jazz songs, which is 48.

The total number of items is 200 songs.

Therefore, we can divide the number of jazz songs by the total number of songs in order to find the percentage of Maya's jazz songs.

To convert a decimal to a percentage, we can move the decimal point two places to the right (aka multiply by 100).

24% of Maya's songs are jazz songs.

Answer:

$95.5090 must be deposited monthly

Step-by-step explanation:

From the information given:

The annual interest rate (r) = 4.2% = 0.042

Let assume that an amount Y is deposited, then after one month, it will increase to:

[tex]Y ( 1+ \dfrac{0.042}{12})[/tex]

The total amount after 4 years will be:

[tex]= Y ( 1+ \dfrac{0.042}{12})^{48}+Y ( 1+ \dfrac{0.042}{12})^{47} +Y ( 1+ \dfrac{0.042}{12})^{46} +...+ Y ( 1+ \dfrac{0.042}{12})[/tex]

[tex]= Y ( 1.0035)^{48}+Y ( 1.0035)^{47} +Y( 1.0035)^{46} +...+ Y( 1.0035)[/tex]

Using the sum of a geometric progression:

[tex]= Y (1.0035) \dfrac{ (1.0035^{48}-1)}{(1.0035-1)}[/tex]

[tex]= Y (1.0035) \dfrac{ (1.0035^{48}-1)}{0.0035}[/tex]

The above amount is then equal to $5000

i.e

[tex]= Y (1.0035) \dfrac{ (1.0035^{48}-1)}{0.0035} = 5000[/tex]

[tex]Y = \dfrac{5000\times 0.0035}{(1.0035)(1.0035^{48}-1)} \\ \\ \mathbf{Y = \$95.5090}[/tex]
