Today's cafeteria specials at a high school in Westford are a deluxe turkey sandwich and a chef salad. During early lunch, the cafeteria sold 13 turkey sandwiches and 69 chef salads, for a total of $151. During the late lunch, 61 turkey sandwiches and 41 chef salads were sold, for a total of $143. How much does each item cost?

Answers

Answer 1

Answer:

chef salads = $2

turkey sandwiches = $1

Step-by-step explanation:

two equations can be derived from the question

13t + 69c = 151 eqn 1

61t + 41c = 143 eqn 2

t = turkey sandwiches

c = chef salads

multiply equation 1 by 61 and equation 2 by 13

793t + 4209c = 9211 eqn 3

793t + 533c = 1859 eqn 4

subtract equation 4 from 3

7352 = 3676c

c =2

substitute for c in equation 1

13t + 69(2) = 151

13t + 138 = 151

13t = 151 - 138

13t = 13

t = 1

The ratio of cups of orange juice concentrate to water in a punch recipe is 2 : 5. If Geoffrey used 20 cups of water, how many cups of orange juice concentrate did he use?

Answers

Answer: 8 cups

Step-by-step explanation:

Let the cups of orange juice concentrate that he used be represented by x.

Therefore, based on the information, we can form an equation which will be:

2/5 = x/20

Cross multiply

5 × x = 2 × 20

5x = 40

x = 40/5

x = 8

Therefore, he used 8 cups of orange juice concentrate.

In an isosceles triangle, the measure of a base angle is 65º. Find
the number of degrees in the measure of the vertex angle.

Answers

Answer:

Your answer is 50 degrees.

Step-by-step explanation:

An isosceles triangles base angles are equal.

A triangle's angles add up to be 180 degrees.

65+65+x = 180

130+x = 180

x = 50

Vertex angle is 50⁰.

What are triangles?

A closed two-dimensional figure with three sides, three angles, and three vertices is called a triangle. The smallest polygon with the fewest sides is the triangle. A triangle can be divided into three categories based on its sides:

Scalene Triangle: Each side measures differently.

Isosceles Triangle - Different sides of a triangle are of a similar measure and the excess side has an alternate measure.

An equilateral triangle has three sides that are all the same size.

Given an isosceles triangle,

measure of base angle = 65⁰

in an isosceles triangle two angles are equal and sum of all the angles is 180⁰, the equal angles are called base angle;

let vertex angle be x , according to triangle property

sum of all the angles is 180⁰,

base angle + base angle + vertex angle = 180

65 + 65 + x = 180

x = 180 - 130

x = 50⁰

Hence the the measure of the vertex angle is 50⁰.

Answers

Answer:

g(x) = 3f(x)

Step-by-step explanation:

We can see that for function g;

When x = 1, y = 3

When x = 2, y = 6

When x = -1, y = -3

When x = -2, y = -6

For function f;

When x = 1, y = 1

When x = 2, y = 2

When x = -1, y = -1

When x = -, y = -2

We can see that the output of g(x) is always 3 times that of f(x) for same values of x.

Thus;

The Fergusons want to install a new tile floor in their kitchen. The kitchen is in the shape of a rectangle and is 9 feet by 12 feet. They have chosen large square tiles that are 2 feet by 2 feet. how many tiles will they need to buy to cover their kitchen floor?

Answers

Answer:

27 tiles

Step-by-step explanation:

First, find the total area of the kitchen.

Use the area formula, A = lw

A = lw

A = (9)(12)

A = 108

So, the area of the kitchen is 108 sq ft

Find the area of the square tiles, using the same formula:

A = lw

A = (2)(2)

A = 4

So, the area of one square tile is 4 sq ft

Find how many tiles they will need to buy by dividing the total area by the area of one tile:

108/4

= 27

So, they will need to buy 27 tiles

Answer:

27 tiles

To find the total area of the kitchen.

We know,

area formula, A = lw

A = lw

A = (9)(12)

A = 108

So, the area of the kitchen is 108 sqft

Now

To find the area of the square tiles

A = lw

A = (2)(2)

A = 4

So, the area of one square tile is 4 sqft

Atlast

Find how many tiles they will need to buy by dividing the total area by the area of one tile:

108/4

= 27

So, Tiles Needed= 27

What are the two elements of a synchronization license? Article ASea otters live in the chilly Northern Pacific Ocean and spend almost all their lives in the water. They sleep, hunt, groom, mate, and give birth in the ocean, where they float on their backs on the water's surface. Adult sea otters spend more than a third of their day grooming their fur. This isn't for vanity; it's for survival. Unlike most sea mammals, sea otters do not have an inner layer of fat to protect them from the cold water. These creatures rely on their dense fur to protect them from the low temperatures. Sea otters have one of the thickest furs in all of the animal kingdom. An adult sea otter's coat can contain up to 1 billion individual hairs! These hairs form a protective, waterproof layer, which traps air and provides insulation. It is crucial that a sea otter's fur is kept clean to maintain this insulating layer between the water and their skin.Article BIn the 1800s, sea otters were hunted for their fur. The fur trade between North America and Europe was booming, and sea otter fur was a popular option because of its thickness. By the mid-20th century, sea otters had been hunted to near extinction. Only 1,0002,000 sea otters were believed to be living in the wild in 1929. Many people thought the species would soon become extinct. However, due to conservation efforts during the second half of the 20th century, sea otter populations recovered. The strengthening of the numbers of sea otters in the wild is often considered to be one of the greatest successes in marine conservation.How do the authors of the two articles address the same topic in these excerpts?
