Answer:

For 45 guests, Nathan should order:

21.6 (or 22) pieces of Fried Chicken

3.3 pounds of Deli Meat

9.675 pounds of Lasagna

Step-by-step explanation:

The information given for each food item is based on 25 people.  If Nathan is going to have 45 guests and plans to only count them as 'half a guest', then we can first take the total number of guests and divide by 2:  45 ÷ 2 = 22.5.  Since the original amounts are based on 25 people, we need to find the percentage of food needed for only 22.5 people:  22.5 ÷ 25 = 0.9 x 100 = 90%.  Since Nathan will only need 90% of the food totals given, we can find how much he should order by multiplying each food amount by 90% or 0.9:

24 x 0.9 = 21.6 or 22 pieces of Fried Chicken assuming you can't buy partial pieces of chicken

3 2/3 or 11/3 x 0.9 = 3.3 pounds of Deli Meats

10 3/4 or 10.75 x 0.9 = 9.675 pounds of Lasagna

Find the value of x to the nearest tenth.
vladimir1956 [14]

Answer:

The answer to your question is  x = 14.7  

Step-by-step explanation:

Data

∠A = 20°

∠B = 46

a = 7

b = x

Process

To solve this problem use, the law of sines. This law states that the ratio of a side of a triangle to the sine of the opposite angle is the same for all three sides.

The law of sines for this problem is

                   x / sin 46 = 7 / sin 20

-Solve for x

                          x = 7 sin 46 / sin 20

-Simplification

                          x = 7 (0.719) / 0.342

                          x = 5.035/0.342

-Result

                         x = 14.7
