Answer:

The rent of 1 chair is $1.5 and rent for 1 table is $8.25.

Explanation:

Given:

A party rental company has chairs and tables for rent.  

Let the rent for a single chair be $m and rent for single table be $n.  

The total cost to rent 8 chairs and 4 tables is $ 45 .  

Then, 8 x $m + 4 x $n = $45  8m + 4n = 45  (1)

The total cost to rent 3 chairs and 2 tables is $ 21.

Then, 3 x $m + 2 x $n = $ 21  3m + 2n = 21  (2)  

To find:

what is the cost to rent each chair and each table?

Solution:

let us solve the above two equations.

Equation(1) x 1 ...........  8m + 4n = 45

Equation(2) x 2..........  6m + 4n = 42 [we multiplied with 2 because, then, coefficient of n equals and easy to cancel

8m + 4n = 45

6m + 4n = 42

(-)----------------------------

2m + 0 = 3  

M = \frac{3}{2} = 1.5

Then, substitute m = 1.5 in (1)

8(1.5) + 4n = 45  

12 + 4n = 45  

4n = 45 – 12

4n = 33  

n = 8.25

Hence, the rent of 1 chair is $1.5 and rent for 1 table is $8.25.

I need to find the missing angle measures.
scoray [572]

Answer:

step 1. b = 102° (vertical angles)

step 2. one complete revolution equals 360°

step 3. a + b + c + 102 = 360

step 4. a + 102 + c + 102 = 360

step 5. a + c = 156°

step 6. 2a = 156 (vertical angles are equal)

step 7. a = 78°, c = 78°.

Whats the radius for the circle? x^2+2x+y^2+4y-6=0
MAXImum [283]

Answer:

r = \sqrt{11}

Step-by-step explanation:

So we need to complete the square for both parts of the equation

First though we can add the 6 to the other side so we have x² + 2x + y² + 4y = 6

So first we can complete the square for x² + 2x

To do so we need to use (\frac{b}{2} )^{2} to figure out the number we need to add to both sides

In this case our b is 2, so substituting this in we get (\frac{2}{2} )^{2} =(1)^{2} =1

Here we add 1 to both sides and now we have x² + 2x + 1 + y² + 4y = 6 + 1

Now we can follow the same steps to complete the square for y² + 4y

Here our b is 4, so substituting this in we get (\frac{4}{2} )^{2}=(2)^{2} =4

Now we add 4 to both sides and now we have x² + 2x + 1 + y² + 4y + 4 = 6 + 1 + 4

Now condensing everything we have (x + 1)² + (y + 2)² = 11

The formula for a circle is (x - h)² + (y - k)² = r²

In our equation we have r² = 11

To find the radius we need to take the square root of both sides \sqrt{r^{2}}  =\sqrt{11} to get r = \sqrt{11}

zhuklara [117]

Answer:

Answers are below

Step-by-step explanation:

I would estimate the numbers as 700 and 40,000

The estimated answer is 700 x 40,000 = 28,000,000

The actual answer is 689 x 39,899 = 27,490,411

The estimated and actual answer are pretty close so this works.

If this answer is correct, please make me Brainliest!
