Harry's Health club costs $20 per month plus a $75 membership fee. Fiona's fitness costs $35 per month. What is the dollar amount at the break even point?

Answers

Answer: The break even point is after 5 months.

First, we need to set up an equation for each plan.

Harry's Health Club can be y = 20x + 75 because it starts at 75 and increase 20 per month.

Fiona's Fitness can be just y = 35x because it is just 35 per month.

Set the equation equal to each other and solve.

20x + 75 = 35x 
75 = 15x
5 = x

A square pyramid and a cube have the same volume if the length of each side of the base of the square pyramid is 2 cm in the height of the cube is 4 cm what is the height of the pyramid

a 8cm
b 16cm
c 24cm
d 48 cm

Answers

Vol sq. pyramid = 1/3×s^2×h
Vol cube = s^3
since height of cube is 4, that height = s
V = (4)^3 = 64 cubic cm
now since their Vs are the same,
1/3×s^2×h = 64
they said length of side in square pyramid
was 2, then:
1/3×(2)^2×h = 64
1/3×4×h = 64
4/3 h = 64
h = 64×3/4 = 16×3 = 48 cm

S = √3*73.5 /4.5=7 (Khufu’s pyramid)

The volume of Khafre’s pyramid is about 9/10 the volume of Khufu’s pyramid. If Kristina wants to make the second model pyramid so its volume is 9/10 the volume of the first model pyramid, what volume should she make the second model pyramid?

This goes with the other questions! if you need information i can get that for you!
Also, could you work it out!

Answers

3/6 should b you answer answer

Final answer:

The  volume will be of 6.3 for the second model.

Explanation:

The student is asked to calculate the volume of the second model pyramid, Khafre's pyramid, which is 9/10 the volume of the first model, Khufu's pyramid. The student has already calculated that, for Khufu's pyramid, S = √3*73.5​/4.5=7. To find the volume Kristina should make the second model, we simply multiply the volume of the first model by 9/10.

Although the question does not provide the exact volume of the first model, we will assume the value of S given is the volume of Khufu's pyramid model. Therefore, the volume of Khafre's pyramid model should be 7 * (9/10) = 6.3.

This result is based on the proportion given between the two pyramids' volumes and is a straightforward calculation of this proportion.

The near and far faces appear to be trapezoids, with bases 12 in and 8 in and height 8 in. Hence each of them has an area
.. Atrapezoid = (1/2)(b1 +b2)h
.. = (1/2)(12 in + 8 in)*(8 in)
.. = 80 in^2

The remaining faces unroll into a rectangle 8 in wide and (12 +8 +8+9) in long. The area of a rectangle is the product of its length and width.
.. Arectangle = length*width
.. = (37 in)*(8 in) = 296 in^2

The total surface area is the sum of the rectangle area and the two trapezoidal faces.
.. Atotal = Arectangle + 2*Atrapezoid
.. = 296 in^2 +2*80 in^2
.. = 456 in^2

The 1st selection is appropriate.

find the separate equations form the lins represented by 3x^2 + 10xy + 8y^2 + 14x + 22y + 15

Answers

3x^2 + 10xy + 8y^2 + 14x + 22y + 15 = 0

3x^2 is factorable only as 3x and x.
15 can be 15 * 1 or 3 * 5.
As a first guess, I place 5 and 3 in that order.
The coefficients of y are unknown so far.

= (3x + Ay + 5)(x + By + 3)

= 3x^2 + 3Bxy + 9x + Axy + ABy^2 + 3Ay + 5x + 5By + 15

(3B + A)xy = 10xy

(3A + 5B)y = 22y

  A + 3B = 10
3A + 5B = 22

-3A - 9B = -30
3A + 5B = 22

4B = 8

B = 2

A + 3B = 10

A + 6 = 10

A = 4


3x^2 + 10xy + 8y^2 + 14x + 22y + 15 = (3x + 4y + 5)(x + 2y + 3)

The product of (3x + 4y + 5)(x + 2y + 3) is indeed
3x^2 + 10xy + 8y^2 + 14x + 22y + 15


The lines are
3x + 4y + 5 = 0
x + 2y + 3 = 0

Joel is looking at costs for using a gym. He could pay $50 per month for unlimited use or he could pay $12 per month plus $4 per visit. How many visits would he have to make each month to make the $50 per month unlimited use option the cheapest one?

Answers


[tex]y = 4x + 12[/tex]
Joel would have to go at least 10 times per month to make the 50 dollars per month the cheapest one.

Answer:

First choice is cheaper.

Step-by-step explanation:

Joel could pay $50 per month for unlimited use or he could pay $12 per month plus $4 per visit.

Let the monthly visits be x

We can define this as :

[tex]12+4x> 50[/tex]

[tex]4x >50-12[/tex]

[tex]4x >38[/tex]

[tex]x> 9.5[/tex]

So, x can be greater than 9.5 means 10.

[tex]4(10)+12>50[/tex]

[tex]52 > 50[/tex]

Comparing both we can say that the first choice is cheaper.

Madeline sold $167 worth of items at a garage sale and then received her $232 paycheck. Estimate how much money she now has by rounding to the nearest ten first and then adding the rounded numbers.

Answers

the answer is 60 dollars

Madeline has approximately $400 after rounding her garage sale earnings and paycheck to the nearest ten and adding them together.

The question involves estimating the total amount of money Madeline has after selling items at a garage sale and receiving her paycheck. To estimate the total amount, we need to round each amount to the nearest ten and then add the rounded numbers together.

First, round $167 to the nearest ten, which is $170.

Next, round $232 to the nearest ten, which is $230.

Finally, add the rounded numbers: $170 + $230 = $400.

21 because first of all let’s start with the fact that 5 years ago a was 8m. Let’s substitute 1 for m if m was one, a would be 8 (five years ago) both add 5, but 13 would not be 3 times older than 6. Let’s then substitute m for 2. Then a would be 16 because 8*2 equals 16. Both add 5 and you get 21 and 7. 21 is 3 time more than 7.

Five years ago the population of Australia was 23.13 million. It has grown by 870 000. What is the population of Australia now?

Answers

23,130,000 + 870,000 = 24,000,000

The current population of Australia is 24 million.

It is given to us that the initial population was 23.13 million and the population 5 year later has grown by 870000 or 0.87 million. Thus to find the current population we simply need to add the initial population and the growth that has happened in 5 years. This gives us:

[tex]Current\ population = 23.13\ million + 0.87\ million = 24\ million[/tex]

Thus, the current population of Australia is 24 million.

A probability experiment is conducted wich of these can not be considered a probability of an outcome: a) 0.222 b) 8.2% c) 0.0234 d) 122.96% e) 5/3 f) 0.45%

Answers

Probability can only range from 0 to 1 and d) 122.96% and e) 5/3 is bigger than 1 so the answer would be d and e.

122.96% and 5/3 cannot be considered probabilities of outcomes in a probability experiment because they are greater than 1. Correct option is d and e.

In probability, the probability of an outcome must be a value between 0 and 1, inclusive. Therefore, any value less than 0 or greater than 1 cannot be considered a probability of an outcome.

Let's check each option:

a) 0.222 - This is a valid probability since it is between 0 and 1.

b) 8.2% - This can be converted to a decimal as 0.082, which is a valid probability since it is between 0 and 1.

c) 0.0234 - This is a valid probability since it is between 0 and 1.

d) 122.96% - This can be converted to a decimal as 1.2296, which is not a valid probability since it is greater than 1.

e) 5/3 - This can be simplified to approximately 1.6667, which is not a valid probability since it is greater than 1.

f) 0.45% - This can be converted to a decimal as 0.0045, which is a valid probability since it is between 0 and 1.

Therefore, options (d) 122.96% and (e) 5/3 cannot be considered probabilities of outcomes in a probability experiment because they are greater than 1. The other options are valid probabilities as they fall within the range of 0 to 1, inclusive.
