1. Michelle and Cameron are selling popcorn for a school fundraiser. Michelle sold 10 tins of cheese
popcorn and 8 tins of caramel popcorn for a total of $446. Cameron sold 22 tins of cheese popcorn and
11 tins of caramel popcorn for a total of $803. Write a system of equations to determine the cost one tin
of cheese popcorn and one tin of caramel popcorn. Show all your work.

Answers

Answer 1

Answer:

one tin of cheese $23

one tin of caramel $27

Step-by-step explanation:

let 'x' = cost of cheese tin

let 'y' = cost of caramel tin

10x + 8y = 446

22x + 11y = 803

i multiplied the first equation by -11 and the second by 8 to eliminate the 'y' terms

  -110x - 88y = -4906

+  176x + 88y = 6424

    66x = 1518

     x = 1518 / 66

     x = 23

find 'y':  10(23) + 8y = 446

             230 + 8y = 446

              8y = 216

               y = 27

A restaurant offers a catering service which costs $25.00 per person with a $119.50 service charge. For parties of 50 or more people, a group discount applies, and the cost is $20.00 per person along with the service charge dropping to $59.00. (a) Write a piecewise-defined linear function which calculates the total cost T of the catering service which serves n people.

Answers

Answer:

T1(n) = 25n +119.50  where n belongs to [tex]1 \leq n <50[/tex].

T2(n) = 20n + 59 where n belongs to [tex]50\leq n[/tex].

Step-by-step explanation:

We are given two situations first is for normal days and the other is for days when 50 or more people are going to this restaurant for the party.

Let the number of person going for this restaurant be "n"

For normal day, we are given

catering service = $25 per person

service charge = $119.50  

Let the total cost of the restaurant be T

Cost for this case will be T1  

T1(n) = 25n +119.50  where n belongs to [tex]1 \leq n <50[/tex]

similarly for the case when 50 or more than that goes to this restaurant for party.

cost after discount

Catering service = $20.00 per person

service charge = $59.00

now the cost of this case will be T2

T2(n) = 20n + 59 where n belongs to [tex]50\leq n[/tex].

Therefore the two piecewise linear functions represents the total cost of the restaurant for serving n people.

Michael spent $700 in April and May and $800 in June and July. His average monthly expenses are:____

Answers

$420+$350+$432=kelsey's monthly expenses  

$700+$800=Micheal's Monthly expenses

Michael's average monthly expenses are $750.

What is the average?

The average value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values. When we need to find the average of a set of data, we add up all the values and then divide this total by the number of values.

Given that, Kelsey spent $350 in May, $432 in June and $420 in July.

Now, average monthly expenses are

(350+432+420)/3

= 1202/3

= 400.67

Michael spent $700 in April and May and $800 in June and July.

Here, (700×2+800×2)/4

= (1400+1600)/4

= 3000/4

= $750

Therefore, Michael's average monthly expenses are $750.

Nora baked 40 cupcakes. She ate 4 cupcakes and gave 25% of the remaining
cupcakes to her neighbours. How many cupcakes did Nora have left?​I want this answer it percentage

Answers

Answer:

27 cupcakes left

In percentage of the number of cupcakes left after she ate 4 = 75%

In percentage of the total number of cupcakes she baked = 67.5%

Step-by-step explanation:

Given that Nora baked 40 cupcakes and ate 4 cupcakes then, the remainder

= 40 - 4

= 36 cupcakes

If she gave 25% of the remaining, the number of cupcakes given

= 25% * 36

= 25/100 * 36

= 9 cupcakes

the number of cupcakes left

= 36 - 9

= 27 cupcakes

In percentage of the number of cupcakes left after she ate 4, this will be

= 100% - 25%

= 75%

In percentage of the total number of cupcakes she baked

= 27/40 * 100%

= 67.5%

What is a triangle?

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.

The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.

There are many types of triangles such that right-angle triangles, equilateral triangles, and much more.

Area of right angle triangle ;

A = (1/2) × Base × Hight

Tan 30° = height/s

1/√3 = height/s

height = s/√3

Now,

A = (1/2) × s × s/√3

A = 1/(2√3)  × s²

Multiply √3 on numerator and denominator

A = √3/6 × s²

Hence "The area of the given triangle is (√3/6) s²".

What are the X- and y-intercepts for the graph of the equation y = 4 - 2x ?​

Answers

Answer:

The x intercept is (2,0)

The y intercept is (0,4)

Step-by-step explanation:

y = 4 - 2x

To find the x intercept, let y =0 and solve for x

0 = 4 - 2x

Subtract 4 from each side

-4 = -2x

Divide by -2

-4/-2 = -2x/-2

2 =x

The x intercept is (2,0)

To find the y intercept, let x =0 and solve for y

y = 4 - 2*0

y = 4

The y intercept is (0,4)

Answers

Answer:

Step-by-step explanation:

f and p are the numbers of fancy and plain shirts

f+p = 12

p = 12-f

20f + 10p = 190

20f + 10(12-f) = 190

20f + 120 - 10f = 190

10f = 70

f = 7

p = 12-f = 5
