The number of boys varies directly as the number of girls and inversely as the number of teachers when there are 24 boys and 16 girls there are 2 teachers how many girls are there when there are 73 boys and 1 teacher?

Answers

Let the number of boys be b, the number of girls be g and that of teachers be t,
thus:
b=kg/t
where k is the constant of proportionality
k=bt/g
b=24, when g=16 and t=2
k=(24*2)/16
k=3
hence:
b=(3g)/2
thus the number of girls when:
b=73 and t=1 will be:
73=(3*g)/1
73=3g
g=73/3
g=24.333~ 24 girls

Lamar’s teacher extended the graph as shown below and asked Lamar to write the function for the graph shown below using f(x) for the function name

Answers

We assume you want to know what Lamar should have written as the definition of f(x).

We know the points (-3, -2) and (2, 3) are on the graph. These differ in both the x-direction and the y-direction by 5, so the slope of the line is 5/5 = 1.

Since the line goes through point (-3, -2) with slope 1, we can use the point-slope form of the equation of a line:
   f(x) = 1(x -(-3)) +(-2)
   f(x) = x +1 . . . . . . . . . . after simplification

Larry's lemons is a street vendor business that sells lemonade and lemon bars. A cup of lemonade sells for $2 and a lemon bar sells for $1.50. When all related business expenses are included, a cup of lemonade costs $0.25 to prepare and a lemon bar costs $0.20 to prepare. Last Monday, one of the vendors selling Larry's Lemons sold at least $500 worth of lemonade and lemon bars and its expenses were no more than $100. At least 150 cups of lemonade were sold. Let x be the number of cups of lemonade sold last Monday and y be the number of lemon bars sold last Monday. Which ordered pair representing a combination of cups of lemonade and lemon bars could have been sold last Monday and make sense in the context of the situation?

Answers

The one possible ordered pair that satisfies all conditions is (x, y) = (150, 134).

The ordered pair (x, y) that satisfies the following conditions:

1. The total revenue from selling x cups of lemonade and y lemon bars is at least $500. This gives us the inequality:

[tex]\[ 2x + 1.50y \geq 500 \][/tex]

2. The total expenses for preparing x cups of lemonade and y lemon bars is no more than $100. This gives us the inequality:

[tex]\[ 0.25x + 0.20y \leq 100 \][/tex]

3. At least 150 cups of lemonade were sold, which gives us the inequality:

[tex]\[ x \geq 150 \][/tex]

To find a combination of x and y that satisfies all these conditions, we can start by considering the minimum number of lemonade cups sold, which is 150. We can then calculate the revenue and expenses for this minimum number and see how many lemon bars would be needed to meet the revenue requirement while keeping the expenses within the limit.

Let's start with the minimum number of lemonade cups:

[tex]\[ x = 150 \][/tex]

The revenue from lemonade alone would be:

[tex]\[ 2 \times 150 = \$300 \][/tex]

The expenses for lemonade alone would be:

[tex]\[ 0.25 \times 150 = \$37.50 \][/tex]

Now, we need to find out how many lemon bars (y) would be needed to make up the remaining revenue to at least $500 while keeping the total expenses at or below $100.

Let's denote the remaining revenue needed as R and calculate it:

[tex]\[ R = 500 - 300 = \$200 \][/tex]

The revenue from selling y lemon bars is $1.50y, so we have:

[tex]\[ 1.50y \geq 200 \][/tex]

[tex]\[ y \geq \frac{200}{1.50} \][/tex]

[tex]\[ y \geq 133.33 \][/tex]

Since we cannot sell a fraction of a lemon bar, we round up to the nearest whole number, so at least 134 lemon bars must be sold.

Now let's check the expenses for the lemon bars. We have $100 - $37.50 = $62.50 left for expenses. The cost to prepare each lemon bar is $0.20, so we calculate the maximum number of lemon bars (y) that can be prepared with the remaining expenses:

[tex]\[ 0.20y \leq 62.50 \][/tex]

[tex]\[ y \leq \frac{62.50}{0.20} \][/tex]

[tex]\[ y \leq 312.5 \][/tex]

Combining the two conditions for y, we find that y must be at least 134 but no more than 312.

Therefore, one possible ordered pair that satisfies all conditions is (x, y) = (150, 134). This means that at least 150 cups of lemonade and at least 134 lemon bars were sold last Monday to meet the revenue and expense conditions.

In a right rectangles pyramid with base edges a= 18 cm and b= 10 cm the slant height toward a is k= 13 cm while the slant height towards b is l= 15 cm. What is the surface area of the pyramid

Answers

To find the surface area of this pier amid, you will find the area of the base and the areas of all for triangular lateral faces. Add these together for the total surface area in the end.

Answer:

Area of the regular pyramid = 16.64 square units.

Step-by-step explanation:

Given  : Regular pyramid .

To find: Find the total area of the regular pyramid.

Solution : We have  given that regular pyramid.

Area = 4 ( area of triangle ) + area of base .

Area of the regular pyramid = 4 ( [tex]\frac{1}{2} * base * height + side * side[/tex].

Area of the regular pyramid =  [tex]4(\frac{1}{2}* 2* \sqrt{10}  + 2*2[/tex]

Area of the regular pyramid =   [tex]4( \sqrt{10} ) + 4[/tex]

Area of the regular pyramid =  (4 [tex]( \sqrt{10} ) \+\ 1[/tex].

Area of the regular pyramid = 16.64 square units.

Therefore, Area of the regular pyramid = 16.64 square units.

Thus,

[tex]2 \leqslant - 0.75(0)\: and \: 2 \leqslant 3(0)- 2[/tex]

[tex]2 \leqslant 0\: and \: 2 \leqslant- 2[/tex]
The above statement is false.


For region 1: We test for

[tex]0 \leqslant - 0.75( - 2)\: and \: 0 \leqslant 3( - 2) - 2[/tex]


[tex]0 \leqslant 1.5\: and \: 0 \leqslant - 8[/tex]
The first statement is true but the second statement is false, so the whole thing is false.



For Region 3: We test

[tex]0 \leqslant - 0.75(2) \: and \: 0 \leqslant 3(2)- 2[/tex]




[tex]0 \leqslant - 1.5 \: and \: 0 \leqslant 4[/tex]

The first statement is false and the second is true so the whole statement is not true.

Answers

2,568 I Think , Sorry If I’m Wrong

57 chairs are needed if everyone is to have a seat

To calculate the number of additional chairs needed, we first need to determine the total number of seats required. This is the sum of the students, guests, and speaker. Then, we subtract the number of chairs already set up to find out the additional chairs needed.

Let's break it down step by step:

1. Total number of seats required:

  - Students: 856

  - Guests: 700

  - Speaker: 1 (assuming the speaker needs a seat)

  Total seats required = 856 (students) + 700 (guests) + 1 (speaker) = 1,557 seats

2. Number of chairs already set up: 1,500

3. Additional chairs needed:

  Total seats required - Chairs already set up = 1,557 - 1,500 = 57

So, Lincoln Technical College needs 57 more chairs to accommodate everyone if all students, guests, and the speaker are to have a seat.

Lincoln Technical College has 856 students and expects 700 guests for a special speaker, making the total number of attendees 1,557. The custodian has already set up 1,500 chairs. To find out how many more chairs are needed, we subtract the number of chairs already set up from the total seats required. This calculation reveals that 57 additional chairs are needed to ensure that everyone has a seat. It's essential to consider all attendees, including students, guests, and the speaker, to accurately determine the total seating requirements.

Answers

We have this equation:

[tex]2x^{\frac{9}{8}} = 111[/tex]

and we need to find the value of x.

First of all, we multiply the whole equation for 1/2, so our goal is to isolate x, therefore:

[tex]x^{\frac{9}{8}}=\frac{111}{2}[/tex]
 
Next step we must do is to apply logarithms:

[tex]logx^{\frac{9}{8}} = log(\frac{111}{2})[/tex]

Next, we have to apply identities and then to solve the equation:

[tex] \frac{9}{8}logx = log(\frac{111}{2})[/tex]
[tex]logx = \frac{8}{9}log(\frac{111}{2})[/tex]
[tex]logx = 1.5504[/tex]
[tex]10^{logx} = 10^{1.5504}[/tex]

Finally, we have the value of x which was our goal. This is the answer for the question above:

The flower garden has the shape of a right triangle. 68 ft of a perennial border forms the hypotenuse of the​ triangle, and one leg is 28 ft longer than other leg. find the lengths of the legs.

Answers

The shorter leg of the triangle is 32 feet long.

The longer leg of the triangle is 60 feet long.

In this case, we are given that the hypotenuse of the triangle is 68 feet, and one leg is 28 feet longer than the other leg. Let's call the length of the shorter leg "x". Then, the length of the longer leg is "x + 28".

Using the Pythagorean theorem, we can write the following equation:

68^2 = x² + (x + 28)²

Simplifying this equation, we get:

4624 = 2x² + 56x + 784

Solving for x, we find that:

x = 32 or x = -60

Since the length of a side of a triangle cannot be negative, we reject the solution x = -60. Therefore, the length of the shorter leg is 32 feet, and the length of the longer leg is 32 + 28 = 60 feet.
