Answer:

338 students.

Step-by-step explanation:

First get the total number of votes.

22+8+18+52=100.

Then find the fraction of stay home which is number of votes for stay home over total number of votes =52/100.

Ans is 52/100 × 650 = 338 students.

Alicia will construct a rectangle that has a height of 4 units and an area of up to 48 square units. Which inequality represents

Nezavi [6.7K]

Answer:

b ≤ 12

Step-by-step explanation:

The area of the rectangle is given by length multiplied by breadth.

The area of the rectangle up to 48 units square means that it can be 48 or less than 48.

If the height given is taken as the width of the rectangle then we can find the base which will be the length of the rectangle.

Area = length * breadth

4units * base ≤ 48 units square

base ≤ 48 units square/4 units

base ≤ 12 units

b ≤ 12 units

HELP PLEASE! IM STUCK--

Answer:

A (first choice), F (last choice)

Step-by-step explanation:

Formulas for arithmetic sequences are generally written in one of two forms. The form you're given here is called an "explicit" formula. For some value of n, you can find the n-th term by evaluating the formula.

The form used in the first three answer choices is called a "recursive" formula. The value of the n-th term depends not on 'n', but on the previous term.

These two forms can be converted to each other like this:

explicit formula ⇔ recursive formula

$A(n)=A_1+d(n-1)\quad\Leftrightarrow\quad\begin{cases}a_1=A_1\\a_n=a_{n-1}+d\end{cases}$

The values of the first term (A₁), the common difference (d), and the term index number (n) are the same in both forms. Once you see this relationship, you should be able to find ...

the first term
the common difference
the other formula for the same sequence

Here, the given function tells you ...

A₁ = 5
d = +4

This means the formulas that describe the same sequence are ...

$\square\ \begin{cases}a_1=5\\a_n=a_{n-1}+4\end{cases}\\\\\square\ A(n)=5+4(n-1)$

_____

Additional comment

The commutative property of multiplication tells you that (n-1)(4) = 4(n-1). The order of the operands makes no difference. The given function has the first of these forms, the offered answer choices have the second of these forms.
