Answer:Given that y represents the cost, and x represents the number of classes, to complete the statements, the table is given for Gymnastics while the equation, y = 18x + 20 is given for Ice-skating program.

Since the table already shows the cost for each specific number of classes for Gymnastics, find that of Ice-skating program for 1, 2, 3, and 4 classes.

For 1 class, substitute x = 1 into y = 18x + 20:

y = 18(1) + 20

y = $38

For 2 class, substitute x = 2 into y = 18x + 20:

y = 18(2) + 20

y = $56

For 3 class, substitute x = 3 into y = 18x + 20:

y = 18(3) + 20

y = $74

For 4 class, substitute x = 4 into the equation y = 18x + 20:

y = 18(4) + 20

y = $92

From the above, we can conclude that, Gymnastics is less expensive when the classes is 1.

Ice-skating is less expensive  when the classes is 3 or 4.

Step-by-step explanation:

From the given function, When the number of classes is 1 the football is less expensive.

Step-by-step explanation:

104 consumers bought at least one of the three labels, 12 consumers bought labels A and B but not C 44 consumers bought label A and 91 consumers bought none of these labels because of the equations.

To find the number of consumers who buy the product sold under at least one of the three labels, we need to add up the number of consumers who buy the product under each label individually and those who buy the product under multiple labels.

However, we need to be careful not to double count those who buy the product under all three labels. Therefore, the formula for this calculation is:

At least one of the three labels = (A only) + (B only) + (C only) + (A and B only) + (A and C only) + (B and C only) + (A, B, and C)

Plugging in the given values, we get:

At least one of the three labels = 15 + 20 + 28 + 12 + 9 + 12 + 8 = 104 consumers

To find the number of consumers who buy the product sold under labels A and B but not C, we simply use the value given for those who buy only those sold under labels A and B:

Labels A and B but not C = 12 consumers

To find the number of consumers who buy the product sold under label A, we need to add up the number of consumers who buy the product under label A individually and those who buy the product under label A and one or both of the other labels. Therefore, the formula for this calculation is:

Label A = (A only) + (A and B only) + (A and C only) + (A, B, and C)

Plugging in the given values, we get:

Label A = 15 + 12 + 9 + 8 = 44 consumers

Finally, to find the number of consumers who buy the product sold under none of these labels, we subtract the number of consumers who buy the product under at least one of the three labels from the total number of consumers surveyed:

None of these labels = Total consumers - At least one of the three labels = 195 - 104 = 91 consumers

If Ella is 15 meters away from Mary and 9 meters away from Dante, then distance between Dante and Mary are 12 meters away from each other.

It is given that Ella is 9 meter away from Dante and in the Dante is in south of Ella. This means that if we consider a plane ground and mark the directions as north, south, east and west, Ella and Dante will be in north and south direction respectively. Since Mary is in the east direction of Dante, this means She will be in the South East direction of Ella and about 15 meters away from her. This creates a triangular connection between them.

Hence by applying the Pythagoras theorem, we get following equation:

ED^2 + DM^2 = EM^2

where,

ED = Distance between Ella and Dante

DM = Distance between Dante and Mary

EM = Distance between Ella and Mary

9^2 + DM^2 = 15^2

To estimate the value of  ([tex]32.03^{4/5}[/tex]) using linear approximation, we start by finding the differential of the function f(x) = [tex]x^{4/5}[/tex] at the point x = 32.

[tex]f(x) = x^{4/5}[/tex]

[tex]f'(x) = 4/5x^{-1/5}[/tex]

Evaluating [tex]f'(32)[/tex], we get:

[tex]f'(32) = (4/5)(32)^{-1/5} = 0.1585[/tex]

Now, using the linear approximation formula:

[tex]f(x) ≈ f(a) + f'(a)(x - a)[/tex]

where a is the point at which we are estimating the function, we have:

[tex]f(32.03) = f(32) + f'(32)(32.03 - 32)[/tex]

Answer:

burrito $3.00 , taco $1.50

Step-by-step explanation:

using the variables b and t for burrito and taco , then

2t + 2b = 9 → (1)

t + 3b = 10.5 → (2)

multiplying (2) by - 2 and adding to (1) will eliminate t

- 2t - 6b = - 21 → (3)

add (1) and (3) term by term to eliminate t

(2t - 2t) + (2b - 6b) = 9 - 21

0 - 4b = - 12

- 4b = - 12 ( divide both sides by - 4 )

b = 3

substitute b = 3 into either of the 2 equations and solve for t

substituting into (1)

2t + 2(3) = 9

2t + 6 = 9 ( subtract 6 from both sides )

2t = 3 ( divide both sides by 2 )

t = 1.5

1 burrito costs $3.00 and 1 taco costs $1.50

Answer:

Let's start by using the information given in the problem to write an equation for the perimeter of the rectangle:

Perimeter = 2(length + width)

We know that the length of the rectangle is twice its width, so we can write:

length = 2*width

Substituting this expression into the equation for the perimeter, we get:

Perimeter = 2(2*width + width)

Simplifying this expression, we get:

Perimeter = 6*width

We are given that the perimeter is 7 1/3 cm, which we can convert to a mixed number:

Perimeter = 7 + 1/3 = 22/3

Substituting this value into the equation above, we get:

22/3 = 6*width

Solving for the width, we get:

width = 22/3 ÷ 6 = 11/9

Now that we have the width, we can use the expression for the length to find its value:

length = 2*width = 2(11/9) = 22/9

Finally, we can use the formula for the area of a rectangle, A = length * width, to find the area:

A = (22/9) * (11/9) = 242/81 square cm

Therefore, the area of the rectangle is 242/81 square cm.

In a rhombus, all sides are equal in length, so we can write:

AB = BC = CD = AD

Let's use n to represent the length of any of the sides, such as AB. Then, we can write:

AD = AB

Therefore, the expression in terms of n to represent AD in rhombus ABCD is simply:

AD = n

An equation is an expression that shows the relationship between two or more numbers and variables.

Consider that the 10s digit = x

And the units digit = y

x +y = 11                                  

The Sum of the digits = 11

10x + y + 45 = 10y + x            

Then Reversed number is 45 more  than original,

10x - x + y + 45 = 10y              

9x + y + 45 = 10y                    

9x + 45 = 10y - y                    

9x + 45 = 9y

Now, Put x +  y = 11 into the equation just found.

9x + 45 = 9(11 - x)                    

x + 45/9 = 11 - x                      

2x + 5 =     11                          

2x = 11 - 5

2x = 6                                      

x = 6/2

x = 3

Therefore, we have;

x + y = 11

3 + y = 11        

y = 11 - 3

y = 8

In triangle ABC, measure of side BC or a is 8.8 unit

In trigonometry, the cosine rule states that the square of the length of any side of a given triangle is the sum of the squares of the lengths of the other sides minus twice the product of the other two sides multiplied by the cosine of angle included between them.

cosA = (b² + c² - a²)/2bc

Given,

In triangle ABC

A = 49° , b = 10, c = 11

By cosine rule

cosA = (b² + c² - a²)/2bc

cos49° = (10² + 11² - a²)/2(10×11)

0.656 = (100 + 121 - a²)/220
144.32 = 100 + 121 - a²

a² = 221 - 144.32

Answer:

-14 gallon jugs

Step-by-step explanation:

I'm not an expert at solving these algebraically, so I'm going to do this the old-fashioned way: Guess and Check.

Lets sum up our information:

- He bought 19 gallons

- He bought those 19 gallons with 24 jugs

- There are half-gallon and full gallon jugs

We know that if he bought 24 full gallon jugs, he would have 24 gallons of milk, but he only has 19, so this is not the answer

We know that if he bought 23 full gallons jugs and one half-gallon jug, he would have 23.5 gallons of milk, but he only has 19 gallons of milk, so this is also not the answer.

We keep reducing the number of full gallon jugs and increasing the number of half-gallon jugs until we reach 19 gallons total.

After trying different combinations, we can figure out that he bought

-14 gallon jugs

- 10 half-gallon jugs

The principal is 50 and the rate of interest is 0.4.

The principal (P) and the rate of interest (R) can be calculated using the following equations:
P = (400*2)/(440 - 400)
R = (440 - 400)/(P*2)
Substituting the given values in the equations we get:
P = 2000/40 = 50
R = 40/100 = 0.4

To calculate the rate and principal of the sum of money, we can use the formula for simple interest: I = Prt, where I is the interest, P is the principal, r is the rate, and t is the time in years.
Given that the yearly interest for the first year is 400 and for the second year is 440, we can set up two equations:
400 = Prt
440 = Pr( t + 1)
Since the interest is for two consecutive years, the time in the first equation is t and the time in the second equation is t + 1.

We can rearrange the first equation to solve for P:
P = 400 / rt
Substituting this value of P into the second equation gives us:
440 = (400 / rt)( t + 1)
Simplifying and rearranging gives us:
440rt = 400t + 400
40rt = 400
rt = 10

Since we are looking for the rate and principal, we can substitute the value of rt back into the first equation:
400 = P(10)
P = 40
So the principal is 40 and the rate is 10 / t. To find the rate, we can substitute the value of P back into the first equation and solve for t:
400 = 40(10 / t)
t = 10
So the rate is 10 / 10 = 1.
