The perimeter of an equilateral triangle measure 48 inches. The midpoints of the sides of the triangle are joined to form another equilateral triangle with sides that are half the length of the outer triangle. This process is continued until three smaller triangles are created within the first triangle.

Use a geometric series to model the perimeters of the four triangles.

The sum of the perimeters of all four triangles is
inches.

Answer:

64 model cars.

Step-by-step explanation:

What we know.

Cory has 80 cars in his collection.

That is 25% more than Everett has.

We can deduce that the equation would be c = 1.25e.

So, how do we figure out e?

Well, 1.25 is the same as 5/4.

So, find the reciprocal of 5/4 and multiply by 80.

4/5 * 80 = e

64 = e

h = 21

Step-by-step explanation:

10h + 15 = 225

10h + 15 - 15 = 225 - 15

10h = 210

10 ÷ 10h = 210 ÷ 10

HAS A BIG NO SIGN

Step-by-step explanation:

you do 0.047×40 and what ever that gives you you add it to 40 and it will give you the answer

The amount Alicia repaid to the company after 40 days is $254.7.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Advance cash = $250

Daily finance fee = 0.047%

The daily finance fee for 40 days.

= 40 x (0.047% x 250)

= 40 x 0.1175

= $4.7

The total amount paid after 40 days.

= 250 + 4.7

= $254.7

Thus,

The amount paid to the company is $254.7.

Answer:

The first, third, and last statements are true.

Answer:

The correct answer is B, 42.

Step-by-step explanation:

In order to know the answer to the given question, the following logical reasoning has to be made:

The multiple number of 7 that is less than 45 but greater than 40 is 42. This is so since 42 is the result of multiplying 7 by 6 (7 x 6 = 42). In turn, 7 multiplied by 5 is equal to 35 (7 x 5 = 35), which does not exceed the number 40, while 7 multiplied by 7 is equal to 49, which is not less than 45 (7 x 7 = 49).

[tex] \frac{ { \sin}^{2} y}{ { \sec}^{2}y - 1 } = { \cos }^{2} y[/tex]

Step-by-step explanation:

We know that [tex] { \tan }^{2} y = { \sec }^{2} y - 1[/tex]

Also , [tex] { \tan}^{2} y = \frac{ { \sin }^{2} y}{ { \cos }^{2}y } [/tex]

Answer:

H= -16.2

Step-by-step explanation:

Answer:

h = -16.2

Step-by-step explanation:

h + 8.1 = -8.1

Subtract 8.1 from both sides of the equation

h + 8.1 - 8.1 = -8.1 - 8.1

h = -16.2

Step-by-step explanation:

Step-by-step explanation:

(x + 8)²

= (x + 8)(x + 8)

= x² + 2(x)(8) + 8²

= x² + 16x + 64.

The binomial expression (x + 8)² is converted into trinomial in standard form x² + 16x + 64.

A polynomial expression is an algebraic expression with variables and coefficients. Unknown variables are what they're termed. We can use addition, subtraction, and other mathematical operations. However, a variable is not divisible.

The expression is given below.

⇒ (x + 8)²

Simplify the expression, then we have

⇒ (x + 8)²

⇒ x² + 8² + 2·8·x

⇒ x² + 16x + 64

The binomial expression (x + 8)² is converted into trinomial in standard form x² + 16x + 64.

Answer:

it's C

Step-by-step explanation:

You have to plug in the inputs into the n variable to get your answer/output.

Answer:

Step-by-step explanation:

f(n)= 3n+2

hence

1) for n= -2  

f(-2) = 3(-2)+2 =-6+2= -4

2) for n= -1

f(-1) = 3(-1)+2 =-1

3) for n=0

f(0)=3(0)+2 = 2

4) for n=1

f(1) =3(1)+2 =5

5) for n=2

f(2)=3(2)+2 =8

Hence  "C" option is correct
