Answer:

(8+20)÷4+3 = 10

Step-by-step explanation:

Simplify the expression.

(8+20)÷4+3

To simplify this expression, we must take note of the mathematics rule 'BODMAS"

B stands for bracket

O stands for order(power)

D stands for division

M stands for multiplication

A stands for addition

S stands for subtraction

The rule of BODMAS simply implies that in an expression, you must first simplify the bracket, then you can now move on to simplify the powers if there is any, then you can now move on to divide if there is division, then you can now multiply if there is any multiplication in the expression, then you can now move on to add or subtract if there are any in the expression.

Looking at the expression, following the rules of BODMAS, we will first of all add 8 and 20 together to give us 28 since they are in the bracket, and we are to start with the bracket first;

(8+20)÷4+3

28 ÷4 + 3

Then next is division

7 + 3

Then we can now add

Therefore simplifying the expression will give us the value of 10

Whats the common ratio of the sequence 7.04 Q14

julsineya [31]

Answer:

$\frac{1}{4}$

Step-by-step explanation:

The given sequence is a geometric sequence.

We can find the common ratio using any two consecutive terms of the sequence.

$r=\frac{\frac{-1}{10} }{\frac{x-2}{5} }=\frac{-1}{10}\times \frac{-5}{2}=\frac{1}{4}$

The common ratio is $\frac{1}{4}$

Based on past musical productions, a theater predicts selling 400−8p number of tickets when each ticket is sold at p dollars. Us

Dvinal [7]

To earn at least $3,200 in revenue, the ticket prices should be $10 or $40.

<h3>What is an Equation</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

Revenue = number of tickets sold * price per ticket = (400 - 8p)p

Revenue = 400p - 8p²

For no revenue:

400p - 64p² = 0

p = $0 or p = $50

For revenue of atleast 3200:

400p - 8p² = 3200

p = $10 or p = $40

To earn at least $3,200 in revenue, the ticket prices should be $10 or $40.

If m(x) = x2 + 3 and n(x) = 5x + 9, which expression is equivalent to (mn)(x)?

Ilia_Sergeevich [38]

For this case we have the following functions:
$m (x) = x ^ 2 + 3

n (x) = 5x + 9$
Multiplying both functions, we obtain an expression equivalent to (mn) (x).
We have then:
$(mn) (x) = m (x) n (x)
$
Substituting values we have:
$(mn) (x) = (x ^ 2 + 3) (5x + 9)
$
Rewriting the expression we have:
$(mn) (x) = (5x ^ 3 + 15x) + (9x ^ 2 + 27)

(mn) (x) = 5x ^ 3 + 9x ^ 2 + 15x + 27$
Answer:
An expression that is equivalent to (mn) (x) is:
$(mn) (x) = 5x ^ 3 + 9x ^ 2 + 15x + 27$
