A restaurant offers 6 choices of appetizer, 8 choices of main meal, and 5 choices of dessert. A customer can choose to eat just

AleksandrR [38]

Answer:

377 possible meals

Step-by-step explanation:

Let's split this up into 3 cases: one course, two courses, and three courses.

<u>Case 1:</u>

The customer only eats one course. If so, that means they only eat an appetizer, a main meal, or a dessert. There are 6 choices of an appetizer, 8 for a main meal, and 5 for a dessert. Add these together:

6 + 8 + 5 = 19

<u>Case 2:</u>

The customer will eat two courses. If so, that means they eat:

- appetizer + main meal

There are 6 choices for appetizer and 8 for main meal, so in total, there are 6 * 8 = 48 choices.

- appetizer + dessert

There are 6 choices for appetizer and 5 for dessert, so in total, there are 6 * 5 = 30 choices.

- main meal + dessert

There are 8 choices for the main meal and 5 for dessert, so in total, there are 8 * 5 = 40 choices.

So, if the customer eats 2 courses, they have 48 + 30 + 40 = 118 choices.

<u>Case 3:</u>

The customer will eat three courses.

Since there are 6 choices for an appetizer, 8 for a main meal, and 5 for dessert, we multiply them together to get:

6 * 8 * 5 = 240 total choices

Finally add all the total choices from each of the 3 cases:

19 + 118 + 240 = 377 possible meals

James deposited $575 into a bank account that earned 5.5% simple interest each year.

Leona [35]

575* 0.05 = 28.75
28.75* 2.5(yrs) = 71.875
575+ 71.875 = 646.875
therefore, $646.87

The dimensions of a rectangle are such that its length is 3 in. more than its width. If the length were doubled and if the width

Kay [80]

Answer:

The length of the rectangle is 11 inch and its width is 8 inch.

Step-by-step explanation:

Given:

Rectangle $(R_1)$ and rectangle $(R_2)$ .

Let the width of the rectangle be 'x' inch.

Its length = '(x+3)' inch

Area of the rectangle = $(A_1)$

⇒ $A_1$ = $(x)(x+3)$

Now for rectangle $(R_2)$ its width is decreased by 1 inch and length is doubled,the area $(A_2)$ will increased by 66 sq-inch.

So,

$A_2=A_1+66$

According to the question.

⇒ Area of rectangle $(R_2)$ with width '(x-1)' and length '2(x+3)'='(2x+6)' .

⇒ $A_2=(x-1)(2x+6)$

Plugging the values of $A_2$ in terms of $A_1$ .

⇒ $A_1+66= (x-1)(2x+6)$

Plugging $A_1$ = $(x)(x+3)$ into the equation.

⇒ $(x)(x+3)+66=(x-1)(2x+6)$

⇒ $x^2+3x+66=2x^2+6x-2x-6$

⇒ $x^2-2x^2+3x-6x+2x+6+66=0$

⇒ $-x^2-x+72=0$

Now using quadratic formula we can find the value of 'x'.

Quadratic formula, (x)= $\frac{\pm b+\sqrt{b^2-4ac} }{2a}$

x= -9 and x= 8

Discarding the negative value.

Our width = 'x' = 8 inches.

So the length of the rectangle = 11 inches and width of the rectangle = 8 inches.
