If the total cost to rent 2 chairs and 12 tables is $107 and the total cost to rent 5 chairs and 3 tables is $38, then the costs to rent each chair and table are $2.5 and $8.5 respectively. We can solve this question using elimination and substitution methods.

Elimination and substitution methods are involved in solving this problem. We're going to use the variables x for the cost of a chair and y for the cost of a table. The total cost to to rent 2 chairs and 12 tables is $107, so the equation can be written as 2x + 12y = 107. The total cost to rent 5 chairs and 3 tables is $38, so the equation can be written as 5x + 3y = 38.

To find the value for x, we need to eliminate the variable y first. Start by multiplying each term in the second equation by 4.

5x · 4 + 3y · 4 = 38 · 4

20x + 12y = 152

Then, subtract the terms in the second equation from their counterparts in the first equation.

2x   + 12y = 107

20x + 12y = 152 -

-18x  + 0   = -45

Finally, with a little bit of algebraic manipulation, we've got x = 2.5, hence $2.5 is the cost in to rent a chair.

-18x = -45

x = -45/-18

x = 2.5

What about the cost to rent a table? Well, we can substitute 2.5 for x in either of the equations to get the value for y. For instance, we can pick the equation 2x  + 12y = 107 and substitute x with 2.5 to isolate the variable y, like this:

2(2.5) + 12y = 107

5 + 12y = 107

12y = 107 - 5 = 102

y = 8.5

The value for y turns out to be 8.5. So the cost to rent a table is $8.5.

Your question is incomplete, but it was most probably "A party rental company has chairs and tables for rent. The total cost to rent 2 chairs and 12 tables is $107. The total cost to rent 5 chairs and 3 tables is $38. What is the cost to rent each chair and each table?"

Answer:

In order to complete the equation we need to use this method :      

Future Amount = I(1+r)^t

I=Initial Amount

R=Growth rate

T=Time periods

Now that we know that....

Letsss seee:

You started with 55 so

Future Amount = 55(1+r)^t

The growth rate is 73% so we have to convert to decimal so

Future Amount=55(1+.73)^t

Time period is 73% every 2 days and you want to see how large the colony would be after 10 days so you do 10/2:

Future Amount=55(1+.73)^5

Future Amount therefore equals 852.301407 BUT You have to round to the nearest whole number Sooo

Height of cylinder is 5 units

Define Cylinder

               ⇒ V = (π × radius²) × h

We have given,

Slant height of cylinder = √29

Radius is = 2 units

Now, we to have to calculate the height for that we have the formula

h = √l² - r²

where, l = slant height

            r = radius of the circular base

            h = height of the cylinder

Now, for the sake of simplicity

h = √l² - r²

h² =  l² - r²

Now, plug in the values

h² = (√29)² - 2²

h² = 29 - 4

h² = 25

h = 5

Hence, the height of cylinder is 5 units

Step-by-step explanation:

No the two rectangles are not similar as the ratios of the sides are not equal.

Two rectangles are said to be similar if the ratio of the sides of the rectangles are equal.

Now let us consider the given rectangles:

In rectangle ABCD:

AB = 18

AD = 36

In rectangle WXYZ :

WX = 25

XY = 45

Now the ratio of the sides of the rectangle are:

AB/AD = 18 / 36 = 1 / 2

WX/XY = 25 / 45 = 5 / 9

Thus we can see that AB : AD ≠ WX : XY

Hence the rectangles are not similar.

If the ratios of the adjacent sides of two rectangles are equal, then they are similar. A rectangle is a quadrilateral in the Euclidean plane because it has four right angles.

Other definitions include a parallelogram with a right angle or a quadrilateral that is equiangular, where equiangular denotes that all of its angles are equal. A square is a rectangle with four equally long sides.

Whole angle/9x=45

Step-by-step explanation:

sum of all three angles in a triangle is 180 degrees so we can add all of these angles together and set it equal to 180 like this

9x+65+70=180

Simplify

9x+135=180

Subtract both sides of 135

9x+135=180

9x=45

since 9x equals 45 that is how much the angle is

Divide both sides by 9 to find x

1.904 mcg/kg/min is what the client receives.

The number of mcg/kg/minute = flow rate × concentration ÷ mass of client

Flow rate = 12 ml/ hour = 12 /60 = 1/5 = 0.2 ml/min

Formula:

Concentration = mass of dopamine/volume

mass of dopamine = 800mg

volume = 500ml

Concentration = 800/ 500

= 1.6 mg/ml

= 1.6 × 1000 mcg/mg

= 1600 mcg/mg

Here the mass of the client = 70kg

Now calculating mcg/kg/minute = flow rate× concentration÷ mass of client

= 0.08 ml/min × 1600mcg/ml ÷70 kg

= 320/70

= 1.904 mcg/kg/min

Therefore mcg/kg/min is 1.904.

(c) $9.60

Step-by-step explanation:

Polly buys a drink at a convenience store for $1. 80. She also buys a bag of chips.

(a) The ratio of the cost of the chips to the cost of the water is 4:3. Find the cost of the chips.

chips : water = 4 : 3

chips/water = 4/3

c/1.8 = 4/3

3c = 1.8 × 4

c = 0.6 × 4

c = 2.4

$2.40

(b) Polly has $6 to spend. Work out the total amount she spends on a drink and chips as a fraction of the $6. Give your answer in its lowest terms.

4 + 3 = 7

Chips: 4/7

Drink: 3/7

(c) The $6 is 37. 5% less than the amount Polly had to spend last week. Calculate the amount she had last week.

Last week it was 100%.

This week it is 37.5% less.

100% - 37.5% = 62.5%

This week, it is 62.5% of last week.

Let x = last week's amount.

62.5% of (last week's amount) = $6

62.5% × x = 6
