Answer:

There is a 18.18%  discount if a combo meal is purchased.

Step-by-step explanation:

Here, according to the question:

The cost of 1 large drink = $3

The cost of 1 order of fries = $4

The cost of 1 hot dog = $4

Now, the combined cost of all items if purchased individually

=  Price of { 1 large drink +  1  fries+  1 hot dog} = { $3 + $4 + $4} = ($11)

Also, the price of all 3 food if a meal is purchased  = $9

So, the difference in the Price of meal and total food cost

= $11 - $ 9 = $2

⇒ There is $2 DISCOUNT of a meal is purchased then buying items individually.

\textrm{Discount Percentage} = \frac{\textrm{Discount}}{\textrm{Total Cost}} \times 100  \\ = \frac{2}{11} \times 100  = 18.18

Hence, there is a 18.18%discount if a combo meal is purchased.

Make sure it's fully reduced.<br><br> 2 - x = 5/8
postnew [5]

Isolate the x. Note the equal sign. What you do to one side, you do to the other.

First, subtract 2 from both sides

2 (-2) - x = (5/8) - 2

-x = 5/8 - 2

Make sure they have the same denominator. Remember that what you multiply to the denominator, you multiply the numerator:

-x = 5/8 - 16/8

-x  = - 11/8

Isolate the x. Divide -1 from both sides

(-x)/-1 = (-11/8)/-1

x = 11/8

11/8 is your answer for x

Answer:

506.7 cm²

Step-by-step explanation:

The amount of cardboard needed would be the surface area of the cone,

S= pi(r)(l+r) where r is the radius and l is the slant height.

You can find l using the Pythagorean theorem. l²=r²+h² which is l²=6²+20² and you get l = √436.

Plug r and l into the equation: S = 6pi(√436 + 6) = 506.7 cm²

Let me know if you have any questions about my steps!

thomas has 6.35 in dimes and quarters the number of dimes is three more than three times the number of quarters how many quarts
Feliz [49]

Answer:

11 quarters

Step-by-step explanation:

If Thomas ignores the extra 3 dimes, he can arrange his coins in groups of 3 dimes and 1 quarter, each group valued at 55¢. It takes

... 6.05/0.55 = 11

groups to bring the total value to the $6.05 remaining after ignoring the extra dimes.

Thomas has 11 quarters and 36 dimes.

If A(-5,7), B(-4,-5), C(-1,-6) and D(4,5) are the vertices of a quadrilateral, find the area of the quadrilateral ABCD.
MrMuchimi
After plotting the quadrilateral in a Cartesian plane, you can see that it is not a particular quadrilateral. Hence, you need to divide it into two triangles. Let's take ABC and ADC.

The area of a triangle with vertices known is  given by the matrix
M = \left[\begin{array}{ccc} x_{1}&y_{1}&1\\x_{2}&y_{2}&1\\x_{3}&y_{3}&1\end{array}\right]

Area = 1/2· | det(M) |
        = 1/2· | x₁·y₂ - x₂·y₁ + x₂·y₃ - x₃·y₂ + x₃·y₁ - x₁·y₃ |
        = 1/2· | x₁·(y₂ - y₃) + x₂·(y₃ - y₁) + x₃·(y₁ - y₂) |

Therefore, the area of ABC will be:
A(ABC) = 1/2· | (-5)·(-5 - (-6)) + (-4)·(-6 - 7) + (-1)·(7 - (-5)) |
             = 1/2· | -5·(1) - 4·(-13) - 1·(12) |
             = 1/2 | 35 |
             = 35/2

Similarly, the area of ADC will be:
A(ABC) = 1/2· | (-5)·(5 - (-6)) + (4)·(-6 - 7) + (-1)·(7 - 5) |
             = 1/2· | -5·(11) + 4·(-13) - 1·(2) |
             = 1/2 | -109 |
<span>             = 109/2</span>

The total area of the quadrilateral will be the sum of the areas of the two triangles:

A(ABCD) = A(ABC) + A(ADC) 
               = 35/2 + 109/2
               = 72
