Given :

Marvelous Meals charges $700 plus $35 per person. Posh Parties charges $425 plus $50 per person.

To Find :

Which company will cost less.

Solution :

Let, after x people Marvelous Meals charge less than Posh Parties :

So, 700 + 35x < 425 + 50x

275 < 15x

x > 18.33 i.e x > 18

Therefore, after 18 people Marvelous Meals charge less than Posh Parties.

Hence, this is the required solution.

Answer:

Add the square of half of the coefficient of [tex]x[/tex] to both sides

[tex]\left(-\dfrac92\right)^2=\dfrac{81}{4}[/tex]

Completing the square:

Rewrite  [tex]x^2-9x+2=0[/tex]  in the form  [tex]y=(x-b)^2 +c[/tex]

Add the square of half of the coefficient of [tex]x[/tex] to both sides:

[tex]\implies x^2-9x+2+\left(-\dfrac92\right)^2=\left(-\dfrac92\right)^2[/tex]

[tex]\implies x^2-9x+2+\dfrac{81}{4}=\dfrac{81}{4}[/tex]

[tex]\implies\left(x-\dfrac92\right)^2 +2=\dfrac{81}{4}[/tex]

[tex]\implies\left(x-\dfrac92\right)^2 +2-\dfrac{81}{4}=0[/tex]

[tex]\implies\left(x-\dfrac92\right)^2 -\dfrac{73}{4}=0[/tex]

[tex]\implies\left(x-\dfrac92\right)^2 -\dfrac{73}{4}=0[/tex]

Answer:

a) [tex]a_{n}[/tex] = 13.8 + 0.2n

Step-by-step explanation:

Given :-

a = 14

d = 0.2

To Find :

[tex]a_{n}[/tex]

Solving :-

[tex]a_{n}[/tex] = a + (n - 1)d

[tex]a_{n}[/tex] = 14 + 0.2n - 0.2

[tex]a_{n}[/tex] = 0.2n + 13.8

Solution :-

a) [tex]a_{n}[/tex] = 13.8 + 0.2n

Answer:

The custodian will be able to repaint 7 bookcases with the amount of paint.

Step-by-step explanation:

The custodian  has  5 1/4 gallons of  paint, to find the number of bookcases the custodian will be able to repaint with this amount of paint if each bookcase requires 3/4 gallons, then we will simply divide 5 1/4 by 3/4 to give  us the number.

But first we need to change 5 1/4 to improper fraction,

thus; 5 1/4 =  

5 1/4 ÷3/4   =   ÷

(We will want to change the division sign to multiplication, to do that, we will have to take the inverse of 3/4 which is 4/3 hence;

                   = ×

4 will cancel out 4 hence;

                    =

                    = 7

Therefore the custodian will be able to repaint 7 bookcases with the amount of paint.

Answer:

-3

Step-by-step explanation:

We are trying to find where the solution is for the systems of equations. This happens when the 2 graphs intersect.

We see that one of our intersection points is (-1, 0), or x = -1 and y = 0.

The other intersection point is (-4, -3), or x = -4 and y = -3.

Therefore, our answer is the 2nd option, -3.

Answer:

x+23 = 47

Step-by-step explanation:

Let age of Carlos is x. It is mentioned that the sum of age of Carlos and his mother is 47 years old. Age of Carlos is 23.

We need to find the equation that represents the sum of Carlos' age with his mother.

x+23 = 47 is the required equation.

Also, we can find the age of Carlos as :

x = 47 - 23

= 24 years

Hence, the correct option is (B).

Answer:

x = 30°

Step-by-step explanation:

84° + 66° + x = 180°

150° + x = 180°

x = 180° - 150°

x = 30°

Answer:

The value of x is 30°

Step-by-step explanation:

The sum of angles of a triangle is equal to 180°

so, x°+66°+84° = 180°

=> x° + 150° = 180°

=> x° = 180°-150°

=> x = 30°

Answer:don’t know if it’s right but here

Step-by-step explanation: okay so first you need to know is that, that triangle it a 90 degrees so you put 90 degrees minus 45 it will equal to 45 because 45+45= 90 degrees but if the question says put degrees then put it if not then don’t put it.

Answer:

n = 8, m = 11.313

Step-by-step explanation:

Answer:

(i) The surface(sheet) of a conical tent is circular so we must use the formula for the area of a circle to find out;

Given the diameter 14, we must find the radius.

To find the radius we must do 1/2 of the diameter to get the radius.

14 x 1/2 = 7, is the radius

Formula for area of a circle;

a = πr^2

where pi is 3.14 or 22/7, r is the radius which is being squared

Plug in the actual values:

a = πr^2

a = 3.14 x 7^2

a = 3.14 x 49

a = 153.86 square meters, is the area of the conical tent's sheet.

(ii) Since there are 153.86 meters in one sheet, we should multiply that by         $12(because $12 per meter) to get the total cost.

So,

153.86 meters x $12 = $1,846.32, it would cost 1,846.32 dollars.

Answer with step-by-step explanation:

m = 0.8

Firstly, we have to see how many M's we are dividing. On the image, it shows 2m + 2m + m + m = 6m. Then, we divide 6 by 4.8, since is would give us the correct value of m. 4.8 ÷ 6 = 0.8.

Using the probability of complementary events, it is found that there is a 0.75 probability of any other suit.

When two events are complementary, the sum of their probabilities are 1.

In this problem, a diamond card and a card for any other suit are complementary events, hence the equation is:

0.25 + p = 1

p = 0.75.

Thus, there is a 0.75 probability of any other suit.
