Multiply 3 times 2.5 times 1.05 and rounded to the nearest tenth

2 answers:

8 0

When you multiply 3 times 2.5 times 1.05 you'll get 7.875. Rounded to the tenth place you'll get 7.9 because the tenths place is the one right after the decimal point so look at that and the number right after, in this case 8 and 7. Since 7 is >5 you round the next number up. 8 changes to 9 and the answer 7.9

The complete question is

"The cafeteria staff made sandwiches. Each sandwich had either rye or white bread, either ham or turkey, and either cheese or no cheese. The staff made an equal number of each type of sandwich.

The sandwiches were placed on a tray. Without looking, Mary will choose a sandwich.

What are the chances that Mary will get a sandwich with cheese?"

The chances of Mary getting a sandwich with cheese is 1/2.

<h3>How to calculate the number of different ways?</h3>

The number of different sandwiches is calculated by multiplying all of the possibilities for each material being used.

rye or white bread: 2 options

ham or turkey: 2 options

cheese or no cheese: 2 options

So the number of different sandwiches = 2*2*2 = 8.

4 have cheese and 4 have no cheese, as the staff made an equal number of each type of sandwich.

So, The chances of Mary getting a sandwich with cheese is 4/8 = 1/2.

Find the maximum value of the function for the polygonal convex set determined by the given system of inequalities.

V125BC [204]

Answer:

A. at (8,7) the maximum value is 98

Step-by-step explanation:

First draw the region, that is bounded by all

inequalities. This is the triangle with vertices

(6,1), (2,5) and (8,7).

Now you can see where the line f(x,y)=7x+6y

intersect this region. The maximum value will be

at endpoints of this region:

• at (6,1), f(6,1)=7-6+6-1=42+6=48;

at (2,5), f(2,5)=7·2+6.5=14+30=44;

• at (8,7), f(8,7)=7.8+6-7=56+42=98.

Thus, the maximum value of the function is 98 at

the point (8,7).

frika. Quality Assurance
