49.cooling a cake is removed from an oven at 210 f and left to cool at room temperature which is 70 f.after 30 min the temperature of the cake is 140 f.when will it be 100 f

Answers

Heat loss, according to Newton's cooling curve, is exponential. Like a half-life, it operates.

Cake temperature and ambient temperature varied by 140 F. The cake has lost half of that difference after 30 minutes, thus that is the half-life. It will shed another half or 35 F in the next 30 minutes, bringing the temperature to 105 F. It will shed 17.5 F in about 30 minutes, leaving 87.5 F.

The temperature is between the last two, at 100 F, so it will be between an hour and an hour and a half. You get an interpolated result of about an hour and ten minutes.

a cylinder is inscribed in a right circular cone of height 8 and radius (at the base) equal to 6.5. what are the dimensions of such a cylinder which has maximum volume?

Answers

The radius of such a cylinder will be 8 and height=8/3.

What is a cylinder?

Cylinder is one of the basic 3d shapes, in geometry, which has two parallel circular bases at a distance. The two circular bases are joined by a curved surface, at a fixed distance from the center. The line segment joining the center of two circular bases is the axis of the cylinder. The distance between the two circular bases is called the height of the cylinder. LPG gas-cylinder is one of the real-life examples of cylinders.

Since, the cylinder is a three-dimensional shape, therefore it has two major properties, i.e., surface area and volume. The total surface area(TSA) of the cylinder is equal to the sum of its curved surface area and area of the two circular bases. The space occupied by a cylinder in three dimensions is called its volume(V).

V=πr²h and TSA=2πr²+2πrh where r=radius and h=height.

Now,

In any case, we can let the radius of the inscribed cylinder be x

. That must therefore mean that the height of the cylinder is 8−4/6x

. This makes the volume of the cylinder

V=πx^2(8−2/3x)=π(8x^2−2/3*x^3)

To find the maximum volume of the cylinder we take the derivative of V

with respect to x

and set it to 0

dV/dx=π(16x−2x^2)=0⇒16x−2x^2=2x(8−x)=0

x=0  leads to a trivial case, which leaves us with x=8

. This means that the height is 8−2/3*8=8/3

, and the volume is therefore

V=π⋅8^2⋅8/3

V=512/3π.

Answers

Answer:

100° and 40°

Step-by-step explanation:

In an isosceles, 2 interior angles are equal.

If one angle is 40°, another one of its angles must be also 40°.

Fact of a triangle

Sum of interior angles of a triangle is 180°.

Let the unknown angle be x.

x + 40° + 40° = 180°

x + 80° = 180°

x = (180 - 80)°

x = 100°

So, the other angle is 100°

Hence,

100° and 40° are the possible measures for the other two triangles.

a recipe calls for 112112 cups of mayonnaise and 3838 cups of pecans. how much mayonnaise should be used if 1 cup of pecans is used?

Answers

4 cups of mayonnaise should be used if 1 cup of pecans is used.

As per the given data:

A recipe calls for  [tex]$1\frac{1}{2}[/tex] cups of mayonnaise and [tex]$\frac{3}{8}[/tex] cups of pecans.

First, convert the mixed fraction to an improper fraction.

[tex]$1\frac{1}{2}[/tex] cups of mayonnaise = [tex]$\frac{3}{2}[/tex]

Here we have to determine how much mayonnaise should be used if 1 cup of pecans is used.

This can be determined by using the unitary method.

We may determine the value of one unit from the value of many units and the value of many units from the value of one unit using the unitary technique.

The ratio of the amount of pecans comparing reality and the recipe is:

[tex]$= \frac{1}{\frac{3}{8} }[/tex]

= [tex]$\frac{8}{3}[/tex]

To find the amount of mayonnaise that should be added:

= [tex]$\frac{8}{3}[/tex] × [tex]$\frac{3}{2}[/tex]

= 4

(180°-70°)/2 = 55° to get x

Answer:

Supplementary angles, x = 55

Step-by-step explanation:

Supplementary angles: straight line means both angles add up to 180, this if the outside angle is 110 then the inside angle is 180° - 110° = 70°

Since it is an isosceles triangle, it means both angles are equal to x therefore

You buy 4 mall candle and 2 large candle for $14. Your friend buy 5 mall candle and 3 large candle for $20. What i the cot of each mall candle? of each large candle?

Answers

The cost of 1 mall candle = $1 while the cost of 1 large candle = $5

Let the cost of 1 mall candle = x

Let us assume that the cost of 1 large candle = y

So, in case 1,

As I can buy,

4 mall candles and 2 large candles for $14

So, framing the equation,

We can rewrite it as:

4x+2y = 14-------(1)

As my friend can buy 5 mall candles and 3 large candles for $20

Now again framing the equation,

We can write it as:

5x+3y=20 -------(2)

From (1) and (2), for determining the value of x, we will first make the coefficient of y equal in both cases.

So, multiply the first equation by 3 and the second by 2

We will get,

12x+6y=42 -----(3)

10x+6y=40------(4)

Now subtracting (4) from (3)

We will get,

2x=2

=>x=1

So, for determining the value of y,

We will put the value of x in (1)

So,  4x+2y = 14-------(1)

=> 4+2y=14

Let the cost of each small candle and each large candle be $x and $y respectively.

From first condition, when I can buy the candles,

Cost of 4 smalll candles = $4x

Cost of 2 large candles= $2y

=> $4x + $2y = $14

Reduce the equation, 2x + y = 7 ---(1) ( since, divided by 2)

In case Second, when my friend buy the candles,

Cost of 5 small candles= $5x

Cost og 3 large candles= $ 3x

=> $5x + $3y = $20 or 5x + 3y = 20 --(2)

Now, equation (1) and (2) made a system of linear equations. Linear equations are in two variables x and y . To solve the system of linear equation, we can use Elimination Method,

To make the same cofficient of y variable in both equtions, multiply the equation (1) by 3

=> 3(2x + y ) = 3× 7

=> 6x + 3y = 21 --(3)

Subtracts the eqution (2) from (3) to eliminate y,

=> 6x + 3y - ( 5x + 3y) = 21 - 20

=> 6x + 3y - 5x - 3y = 21 - 20

-3(x+2)^2-4=5 solve by factoring

Answers

Answer: To solve the equation -3(x+2)^2-4 = 5 by factoring, we can follow these steps:

Move all the terms to one side of the equation by adding 3(x+2)^2 and 4 to both sides: -3(x+2)^2-4+3(x+2)^2+4 = 5+3(x+2)^2

Combine like terms: 3(x+2)^2 = 5

Take the square root of both sides of the equation: (x+2)^2 = 5/3

Isolate x+2 on one side of the equation by taking the square root of both sides: x+2 = ±sqrt(5/3)

Solve for x by subtracting 2 from both sides of the equation: x = ±sqrt(5/3) - 2

So the solutions to the equation -3(x+2)^2-4 = 5 by factoring is x = ±sqrt(5/3) - 2.

It's important to note that the square root of a fraction is a positive and negative solution, so the solutions are x = sqrt(5/3) - 2 and x = -sqrt(5/3) - 2

A general linear equation can be written in the slope-intercept form as:

y = m*x + b

Where m is the slope and b is the y-intercept.

Particularly, two linear equations are parallel only if both equations have the same slope and different y-intercepts.

Then a line parallel to:

y = (2/3)*x + 1

Is of the form:

y = (2/3)*x + b

And we want this line to pass through the point (3, 0), replacing these values we will get:

Answers

Distance of the race is 500 feet.

Given that tortoise moves at 50 feets per hour and hare moves at 250 feets per hour.

So speed of tortoise = 50 feets per hour.

Speed of hare = 250 feets per hour.

Let hare takes T hours to complete the race

Than tortoise will take (T + 8) hours to complete the race.

Total distance traveled by hare = speed * time = 250T

Total distance traveled by tortoise = speed * time = 50(T + 8)

Total distance traveled by both is same.

250T = 50(T + 8)

250T = 50T + 400

250T – 50T = 400

Let the number of student tickets be y.

Then we know that the total number of tickets is 238.

x + y = 238 ... (1)

If we multiply the cost of a ticket by the number of tickets we can also get the total.

6. 75x + 3. 50y = 1252. 25(....... (2))

Now we have two equations and two unknowns and we can find the value for these unknowns

Lets use substitution method.

x + y = 238

x = 238 - y

Substitute x = 238 - y in equation (2)

6. 75(238 - y) + 3. 50y = 1252. 25

1606.5 - 6.75y + 3. 50y = 1252. 25

- 3.25y = - 354.25

3.25y =  354.25

y = 109

Substitute y = 109 in equation (1)

x + 109 = 238

x = 129.

Therefore number of student tickets are 109.

The graph shows the population y of a certain city over the course of 10 years x. The equation of the trend line shown is y=1.9x+21

Answers

According to the equation of the trend line the population will reach 52900 in 27831 years.

What is an equation?

A mathematical statement known as an equation is a combination of two expressions joined together by the equal sign.

The equation of the trend line is:

y = 1.9x + 21

where, y is the population and x indicate the year.

To find the number of years in which the population reach 52900, substitute y = 52900.

y = 1.9x + 21

52900 = 1.9x + 21

52900 - 21 = 1.9x

52879/ 1.9 = x

x = 27831

Hence, according to the equation of the trend line the population will reach 52900 in 27831 years.

The local swimming pool is offering two programs. No membership fee and a $5 entrance fee per day OR a one time membership fee of $50 and an entrance fee of $3. 50. How many times will she need to go to make it worth paying the membership fee

Answers

She needs to go to the swimming pool about 14 times for it to be worth paying the membership fee.

To determine how many times you need to go to the swimming pool to make the membership fee worth paying, you can use the following formula:

Number of visits = membership fee / (cost without the membership - cost with membership)

Plugging in the values, we get:

Number of visits = $50 / ($5 - $3.50)

The savings from the membership's lower entrance price will have surpassed the cost of the membership after 14 visits.

Hence, she needs to go to the swimming pool about 14 times for it to be worth paying the membership fee.

On the grid below segment AB is shown with endpoints A(-1,-1) and B(7,5). Its midpoint, M, is also
labeled and has coordinates of M (3, 2).

(a) Draw the perpendicular bisector of AB on the grid. Think about its slope compared to that of AB.
b) Write the equation of the line you drew in (a).

Answers

The slope of the line AB and the perpendicular bisector are reciprocal to each other and the equation of the line is 3y + - 4x = 18.  

Perpendicular bisector:  

A line is known as a perpendicular bisector when it divides a specified line segment in half, by creating a 90° angle at the intersection.

The intersection of a line segment's midpoint with a perpendicular bisector. It can be built with a compass and a ruler.

On both sides of the line segment being divided, it forms a 90° angle.

Here we have

On the grid below segment AB is shown with endpoints A(-1,-1) and B(7,5). It's midpoint M. The coordinates of M (3, 2).  

Slope from A(-1,-1) and B(7,5)  

=> [ 5 + 1]/[7 + 1 ] = 6/8 = 3/4

When we draw a perpendicular bisector of AB on the grid. It will pass through the point (0, 6)  

The slope of the perpendicular bisector i.e from (0, 6) to (3, 2)  

=> [2 - 6]/[3 - 0] = - 4/3

Let the equation of the bisector is y = mx + c

=> y = (-4/3)x + c

=> 3y = - 4x + 3c           [ ∵ Slope = -4/3 ]

As we know the bisector will pass through (3, 2)

=> 3(2) = -4(3) + 3c

=> 3c = 12 + 6

=> 3c = 18

Hence, the required equation of the line is 3y = - 4x + 18  

Therefore,

The slope of the line AB and the perpendicular bisector are reciprocal to each other and the equation of the line is 3y + - 4x = 18.
