Juan, standing at one focus of a whispering gallery; is 20 ft from the nearest
wall. His friend is standing at the other focus, 80 ft away. How high is its elliptical
ceiling at the center?
Fill in the blank:
The elliptical ceiling is
ft high at the center.
Give your answer to the nearest whole ft (no decimal places).

Answers

Answer 1

The elliptical ceiling is approximately 30 ft high at the center.

To find the height of the elliptical ceiling at the center, we can use the properties of an ellipse.

In this case, the two foci of the ellipse represent the positions where Juan and his friend are standing.

The distance between the two foci is 80 ft, and Juan is 20 ft away from the nearest wall.

This means that the sum of the distances from any point on the ellipse to the two foci is constant and equal to 80 + 20 = 100 ft.

Since Juan is standing at one focus and the distance to the nearest wall is given, we can determine the distance from Juan to the farthest wall by subtracting the distance to the nearest wall from the sum of the distances.

Distance from Juan to the farthest wall = 100 ft - 20 ft = 80 ft.

The height of the elliptical ceiling at the center is equal to half of the distance between the nearest and farthest walls.

Height of elliptical ceiling = (80 ft - 20 ft) / 2 = 60 ft / 2 = 30 ft.

The Blazers hockey team has won 5 of its first 12 games. No game was tied. The Rockets’ record is 5 wins and 3 losses. Which team has the better record?
help please

Answers

Answer:

The Rockets' team has the better record.

Step-by-step explanation:

The Blazers hockey team has played 12 games but they won only 7 out of the 12 games, so that means that they loss the other 5 games. So that makes the Blazers record 7 wins and 5 losses.

The Rockets' team has played 8 games but they won only 5 out of the 8 games, so that means that they loss the other 3 games. So that makes the Rockets' record 5 wins and 3 losses.

So, the Rockets' team has the better record because they loss less games than the Blazers team did.

The values of F, G and H are given as follows:

F = 5, G = 29, H = 1.

How to obtain the values of F, G and H?

The expression at the right side of the equality represents the entire expression after the least common factor is applied at the left side.

The least common side of the denominators is given as follows:

(x - 3)(4x + 7).

Hence the simplified numerator is given as follows:

(2x + 1)(4x + 7) + (-3x + 2)(x - 3).

Expanding the operations, and combining the like terms, we have that:

(2x + 1)(4x + 7) + (-3x + 2)(x - 3) = 8x² + 18x + 7 - 3x² + 11x - 6.

(2x + 1)(4x + 7) + (-3x + 2)(x - 3) = 5x² + 29x + 1.

Then the equality of the two numerators is given as follows:

5x² + 29x + 1 = Fx² + Gx + H.

Hence the values of the letters are given as follows:

kira,boris,deshuan have a total of $119 in their wallets. Boris has 3 times waht deshuan has. Deshuan has $6 more than kira. How much do they have in their wallets.

Answers

Kira has $19, Boris has $75, and Deshuan has $25.

How much money does each person have in their wallets?

We will denote as follows:

Kira has as K, Boris has as B, and Deshuan has as D.

From information, we can set up equations:

B = 3D (Boris has 3 times what Deshuan has)

D = K + 6 (Deshuan has $6 more than Kira)

K + B + D = 119 (The total amount of money they have is $119)

Substituting equation 2 into equation 1, we have:

B = 3(K + 6)

Substituting equations 1 and 2 into equation 3:

K + 3(K + 6) + (K + 6) = 119

K + 3K + 18 + K + 6 = 119

5K + 24 = 119

5K = 119 - 24

5K = 95

K = 95 / 5

K = 19

Using equation 2, we can find D:

D = K + 6

D = 19 + 6

D = 25

Using equation 1, we can find B:

B = 3D

B = 3 * 25

B = 75.

Pamela is 15 years younger than Jiri. The sum of their ages is 81. What is Jiri's age?

Answers

Answer:

Step-by-step explanation:

STEP 1

Let Jill's age be equal to: x

Let Pamela's age be equal to :Jiri's age(x) - 15

STEP 2

Total sumof Jiri and Pamela's age= 81

Sum= Pamela's age + Jiri's age

81 = (x-15) + x

81 =x -15 + x

81 = x+x -15

81= 2x -15

Collect like terms

81 + 15= 2x ( recall - changes to + when crossing the =)

96=2x

Divide both sides by 2

96/2 =2x/2

48 = x

Recall Jiri's age is equal to x

Hence Jiri's age is equal to 48

Answers

The set of the expression (A ∪ B) ∩ (B ∩ C') is {2, 3, 6}.

What is set?

Sets in mathematics, are simply a collection of distinct objects forming a group. A set can have any group of items, be it a collection of numbers, days of a week, types of vehicles, and so on. Every item in the set is called an element of the set.

Given that, U = {1, 2, 3, 4, 5, 6, 7, 8}, A = {6, 8, 2}, B = {3, 2, 5, 6}, and C = {5, 1, 7}.

If U is a universal set and A be any subset of U then the complement of A is the set of all members of the universal set U which are not the elements of A.

So, complement of set C is C'={2, 3, 4, 6, 8}

Now, (A ∪ B) ∩ (B ∩ C')

= ({6, 8, 2}∪{3, 2, 5, 6}) ∩ ({3, 2, 5, 6}∩{2, 3, 4, 6, 8})

= {2, 3, 5, 6, 8} ∩ {2, 3, 6}

= {2, 3, 6}

Therefore, the set of the expression (A ∪ B) ∩ (B ∩ C') is {2, 3, 6}.
