candy that costs 31 cents per pound is mixed with candy that costs 46 cents per pound to obtain 50 pounds of candy that costs 40 cents per pound. How many pounds of each of the two types of candy are in the mix?

Answers

Answer:

20 lb of 31 cent candy, 30 lb of 46 cent candy

Step-by-step explanation:

sorry don't have one

here is a smiley face for you

:D

The amount of each type of candy (in pounds) that are mixed for the considered condition is: 20 pounds of first type of candy and 30 pounds of second type of candy.

How to form mathematical expression from the given description?

You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.

For this case, we can assume the separate weights of each type of candies to be represented by variables.

Let we have:

x = weight (in pounds) of first type of candy whose cost is 31 cents per pound.y = weight (in pounds)  of second type of candy whose cost is 46 cents per pound.

x pounds of first type of candy is mixed with y pounds of second candy.

The weight of the mixture = x + y = 50 pounds

The cost of the mixture = 40 cents per pound  = [tex]40 \times 50 = 2000[/tex] cents

Cost of the mixture = cost of x pounds of first candy+ cost of y pounds of second candy = [tex]31x + 46y[/tex]
Thus, we get [tex]31x + 46y =2000[/tex]

Therefore, we got a system of two linear equations as:

[tex]x +y = 50\\31x + 46y =2000[/tex]

From first equation, we get:

[tex]x = 50 -y[/tex]

Substituting this value in second equation, we get:

[tex]31(50-y) + 46y =2000\\1550 + 15y = 2000\\15y = 450\\\\y = 450/15 = 30[/tex]

Putting this value of y in equation for x, we get:

[tex]x = 50-y = 50-30 = 20[/tex]

Thus, the amount of each type of candy (in pounds) that are mixed for the considered condition is: 20 pounds of first type of candy and 30 pounds of second type of candy.

The equation of the circle with a center of (4,5) and a radius of 2 units is (x + 5)² +(y + 8)² = 4

How to determine the circle equation?

The center of the circle is given as:

Center (a,b) = (-5, -8)

The radius is given as:

Radius, r = 2

The equation of the circle is calculated using:

(x - a)² + (y - b)² = r²

Substitute values for r and (a,b)

(x + 5)² +(y + 8)² = 2²

Evaluate the square of 2

(x + 5)² +(y + 8)² = 4

Hence, the equation of the circle is (x + 5)² +(y + 8)² = 4

2. Determine the y – intercept, zeros, the equation of the axis of symmetry and vertex of each quadratic
relation.
y = (x − 3)(x+3)

Answers

[tex]\\ \rm\rightarrowtail y=(x-3)(x+3)=x^2-9[/tex]

Zeros are x intercepts

(3,0) U(-3,0)

#2

Y intercept=-9

#3

Axis of symmetry=x=0

#4

Vertex=(0,-9)

Answer:

Given quadratic equation:  y = (x - 3)(x + 3)

Zeros (x-intercepts)

The zeros of a quadratic equation are the points where the graph of the quadratic equation crosses the x-axis.  So the x-intercepts (zeros) are when y = 0

⇒ (x - 3)(x + 3) = 0

⇒ (x - 3) = 0  so  x = 3

⇒ (x + 3) = 0  so  x = -3

Therefore, the x-intercepts are at (3, 0) and (-3, 0).

y-intercept

The y-intercept is the point where the graph crosses the y-axis.  So the y-intercept is when x = 0

⇒ (0 - 3)(0 + 3) = -9

Therefore, the y-intercept is at (0, -9)

Vertex

Expand the equation so that it is in standard form y = ax² + bx + c:  

⇒ y = x² - 9

x-value of vertex is -b / 2a ⇒ -0 / 2 = 0

substitute the found value of x into the equation to find y:

⇒ y = (0)² - 9 = -9

Therefore, the vertex is (0, -9)

Axis of symmetry

Axis symmetry of a quadratic equation is x = a where a is the x-value of the vertex.

Therefore, the axis of symmetry is x = 0

At the movie theatre , child admission is $ 6.40 and adult admission is $ 9.60 . On Monday , 153 tickets were sold for a total sales of $ 1270.40 . How many adult tickets were sold that day ?

Answers

Answer:

91 adult tickets

Step-by-step explanation:

Algebra is really useful here:

Let a = number of adult tickets sold and c = number of child tickets sold.

Thus, we can say that

a + c = 153 (number of tickets)

6.40c + 9.60a = 1270.4. (cost of all of the tickets)

Solving,

c = 153 - a

6.40(153 - a) + 9.60a = 1270.4

979.2 - 6.40a + 9.60a = 1270.4

3.20a = 291.2

a = 91

Find the equation of the line passing through the given point and

(5,3) and y = x + 4

Answers

Answer:

y= x -2

Step-by-step explanation:

Slope-intercept form:

y= mx +c, where m is the slope and c is the y-intercept

Given equation: y= x +4

This equation is already in the slope-intercept form, thus its slope can be found from the coefficient of x.

Slope= 1

[tex]\textcolor{steelblue}{\text{Parallel lines have the same slope.}}[/tex]

Slope of unknown line= 1

Substitute the m= 1 into y= mx +c:

y= x +c

To find the value of c, substitute a pair of coordinates the line passes through into the equation.

When x= 5, y= 3,

3= 5 +c

c +5= 3

c= 3 -5

c= -2

Thus, the equation of the line is y= x -2.

In the early days of arctic exploration, dogsled was often the only way to travel. The ice, snow, and extremely cold weather made using other animals, such as horses, impossible. Snowmobiles were not invented yet. Most explorers journeyed by ship until the ice made it impossible to continue. Then, they would switch to dogsled. The dogs, working together, were a well-oiled machine that could cover long distances in the cold. Sled dogs needed to have long, warm coats to survive the arctic temperatures. They had to be fast and able to run for long distances while pulling a heavy load. Most importantly, they had to work together as a team. This made northern dogs, such as Siberian huskies and Alaskan malamutes, the best choices for the sled teams. These dogs have long coats, with a double layer of fur to keep out the cold, and they have wide paws with webbed toes that act like snowshoes. They have been bred for more than 9,000 years to be working dogs in extreme winter weather. They are friendly, team-oriented, and purposeful dogs. In the days of the arctic explorers, the physical features and determined personalities of the sled dogs made long journeys in harsh conditions possible. To be in the best condition for pulling heavy loads, the dogs needed a diet that was high in fat. They ate whale and seal blubber and fatty meats during their long journeys, which kept them strong and gave them energy to keep going. The dogs' paws also needed special care to make sure that they did not become injured by sharp ice or extreme cold. Treating the paws with fat or wax helped the dogs to run safely and comfortably. Although the days of arctic explorers are long past, sled dogs continue to run through the snow and ice of the North. Dogsledding is now recognized as a sport, with many competitions taking place all over the world. One of the most well-known of these is the Iditarod, a race of almost 1,000 miles. It commemorates the Great Race of Mercy that took place in 1925 when dog sled teams were the only hope of a town that needed life-saving medicine. The race takes 811 days to complete and is run regardless of weather conditions. Teams of twelve or more dogs train with their handlers for years before competing. The race is long and one of the most challenging in the world. Dogs and their handlers must be in top physical condition to have any chance of winning.During the race, the dogs get multiple rest stops and are checked by veterinarians to make sure they avoid injuries. They eat high-fat, high-protein foods to give them the energy to continue, just like the dogs of the arctic explorers did. With the same determination that drove the dogs of the 1925 Great Race of Mercy, the dogs competing in the Iditarod run through even the worst blizzards and race to win.Which reason supports the author's point that dogs and their handlers must be in top physical condition to compete in the Iditarod? Dogsledding is now recognized as a sport, with many competitions throughout the world. Sled dogs need special diets and care to prevent injury or sickness. The race commemorates the extraordinary Great Race of Mercy that took place in 1925. The race is 1,000 miles long and challenging, taking place no matter the weather conditions. 3.
