Answer:

Interpret the structure of expressions, expressions that represent a quantity in terms of its context, parts of an expression, such as terms, factors, and coefficients, complicated expressions by viewing one or more of their parts as a single.

Interpret the structure of expressions. Interpret expressions that represent a quantity in terms of its context. Interpret parts of an expression, such as terms, factors, and coefficients. Interpret complicated expressions by viewing one or more of their parts as a single entity.

hear is some more things a about Interpret Expressions Interpret the expression.
The expression 8n+5.5n represents the following situation:
A group of n friends went to the movies. Each bought a ticket for $8, and each also bought the snack special for $5.50.

(a) Explain what each term in the expression 8n+5.5n represents.
The term 8n is the product of 8 and n. The number 8 represents the price of a ticket, and n represents the number of friends who went to the movies. So what does the product 8n represent?

The term 8n represents the total amount the friends paid for tickets.

The term 5.5n is the product of 5.5 and n. The number 5.5 represents the price of the snack special, and n represents the number of friends who went to the movies. So what does the product 5.5n represent?

The term 5.5n represents the total amount the friends paid for the snack special.

Think About ItHow are 8n and 5.5n related? Each term represents a total amount paid by the group of friends while they were at the movies.
(b) Explain what the expression 8n+5.5n represents.
The term 8n represents the total amount the friends paid for tickets, and the term 5.5n represents the total amount the friends paid for the snack special. So what does their sum represent?

The expression 8n+5.5n represents the total amount the friends paid at the movies.

(c) The expression n(8+5.5) is equivalent to the expression 8n+5.5n. Explain what each factor in the expression

The lengths of the legs of a right triangle are consecutive even integers. The hypotenuse is 58 inches. What is the sum of the l

miskamm [114]

Answer:

82 inches

Step-by-step explanation:

The difference between consecutive even integers is 2, thus

let the legs be n and n + 2

Using Pythagoras' identity in the right triangle

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

n² + (n + 2)² = 58² ← expand and simplify left side

n² + n² + 4n + 4 = 3364 ( subtract 3364 from both sides )

2n² + 4n - 3360 = 0 ( divide all terms by 2 )

n² + 2n - 1680 = 0 ← in standard form

(n + 42)(n - 40) = 0 ← in factored form

Equate each factor to zero and solve for n

n + 42 = 0 ⇒ n = - 42

n - 40 = 0 ⇒ n = 40

But n > 0 ⇒ n = 40

and n + 2 = 40 + 2 = 42

Thus sum of legs = 40 + 42 = 82 inches

Help please!! Define the following sequence recursively 11,33,55,77

yulyashka [42]

Answer:

Step-by-step explanation:

Recursive sequences generally look like this:

a1 = something

an= ahhhhhh

The 1st term in this sequence is 11.

So we have

a1=11

And now we see that each term is adding by 22.

We have,

a1=11

$a_{n} =a_{n-1}+22$

Find the distance between two points. ENTER THE NUMBER THAT GOES BENEATH THE RADICAL SYMBOL.

iVinArrow [24]

<h2>The distance between two points is $\sqrt{98}$ or 9.9 units</h2>

Solution:

The distance between two points is given as:

$d = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}$

From given,

$(x_1, x_2) = (-5, 5)\\\\(x_2, y_2) = (2, -2)$

Substituting the values we get,

$d = \sqrt{(2+5)^2+(-2-5)^2}\\\\d = \sqrt{7^2+(-7)^2}\\\\d = \sqrt{49+49}\\\\d = \sqrt{98}\\\\d = 9.899 \approx 9.9$

Thus the distance between two points is $\sqrt{98}$ or 9.9 units
