Step-by-step explanation:

The independent variable represents the cost of the meal for 70 people.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given when the manager quotes a price for a banquet, she is including the cost of renting the room plus the cost of the meal for each person. A banquet for 70 people costs $1300. For 120 people, the cost is $2200.

The expression will be written as,

Total cost = 70x + cost of rent

Therefore, the independent variable represents the cost of the meal for 70 people.

Answer:

Simplified improper fraction.

Step-by-step explanation:

A simplified proper fraction would not have a numerator bigger than the denominator.

An improper fraction would have a numerator bigger than the denominator that can be simplified.

We see here that the expression isn't proper as it can be simplified further. Therefore, it is improper.

Answer: Simplified improper fraction.

20 seconds

Step-by-step explanation:

s = Distance traveled by elevator = 300 ft

t = Time taken = 5 seconds

Velocity is given by

[tex]v=\dfrac{s}{t}\\\Rightarrow v=\dfrac{300}{5}\\\Rightarrow v=60\ \text{ft/s}[/tex]

Distance to the observation level from the lobby = 1200 ft

Time taken is given by

Answer:

Revenue(net profit) = 720.00 £ (-35%)

Step-by-step explanation:

Given that Poppy Lapel Pins made 1000 Poppy Lapel Pins that costed £1.10 each to make. This is what is subtracted from the sales. Which means 1100£ is what is deducted from the net(total) profit. 1000 * £1.10 = 1110.00£ (cost)

When it says that 35% of these are given to charity, these are the number of pins that they did not make profit off of. It also says the remaining are sold which means that the other 65% are sold since 100%-35% = 65%.

Referring back to how 1000 total pins are sold, we are given that 35% of these are given to charity which are the pins that the company does not make profit off of. Because 35% of these are disregarded from profit 1000 minus 35% of 1000 is 1000 - 350 = 650 pins (number of pins sold for profit).

We are also given that these 650 pins are split up into another set of sales, being 60% of these is sold for 3£ each pin, and the other 40% are sold for 5£ each 2 pins.

Now we can set up an expression to solve for the net profit as a quantity.

(650 × 60% × 3£) + ( 1/2 × 650 × 40% × 5£)

= ( 390 × 3£ ) + ( 260 × 1/2 × 5£) = (1170.00£) + (650£) = (1820.00£).

Then to find the revenue or total income made, we must subtract the *cost* from the *net profit*

Revenue = profit - cost.

Revenue = 1820.00£ - 1100.00£ = 720.00£.

Once that is done, to find the percent margin, we must subtract the revenue from the cost all divided by the cost, and multiplied by 100( to convert it to a precent ).

Margin = ((Revenue-cost)/cost × 100)%

Margin = ((720.00£-1100.00£)/1100£ × 100)% = -380/1100£ × 100%= -0.345454... × 100% ≈ -35%

Answer:

1st Option

Step-by-step explanation:

All angles in a triangle must add up to 180°.

Step 1: Set up equation

40° + 60° + 16x = 180°

Step 2: Rewrite

60° + 16x + 40° = 180°

Answer:

Option: A.

Step-by-step explanation:

Hey there!

In the given triangle;

60° +16x° + 40° = 180° { Sum of interior angle of a triangle}

100° + 16x= 180°

16x = 180° - 100°

[tex]x = \frac{80}{16} [/tex]

Therefore, X= 5°.

So, Option A (equation) is used for solving the value of"X".

Step-by-step explanation:

5| 2n+8| +3 = 33

Subtract 3 from each side

5| 2n+8| +3-3 = 33-3

5| 2n+8| = 30

Divide by 5

5/5| 2n+8| = 30/5

| 2n+8| = 6

An absolute value equation has two solutions, one positive and one negative

2n+8 = 6              2n+8 = -6

Subtract 8 from each side

2n+8-8=6-8          2n+8-8 = -6-8

2n = -2                    2n = -14

Divide by 2

2n/2 = -2/2            2n/2 = -14/2

n = -1                       n = -7
