To make the total monthly cost of Silver Gym and Fit Factor equal, Sarah would have to buy 6 personal training sessions in a single month.

The question is asking to find out how many personal training sessions Sarah would need to take in a month for the cost at Silver Gym to equal the cost at Fit Factor.

To solve this, we need to create an equation. Let's represent the number of personal training sessions as x. For Silver Gym, the total cost in a month would be 30 + 45x, and for Fit Factor, it would be 90 + 35x.

Setting these two expressions equal to each other gives us the equation 30 + 45x = 90 + 35x.

Moving the variable terms to one side and the constants to the other side of the equation gives us 10x = 60.

We solve for x by dividing both sides of the equation by 10 to get x = 6.

This means that Sarah would need to take 6 personal training sessions for the total cost at the two gyms to be equal.

Using the formula for exponential growth and given an initial population of 4,000 mosquitoes with a 25% monthly growth rate, the mosquito population is expected to grow to approximately 9,766 after 4 months.

The question involves calculating the growth of a mosquito population over a period, specifically after 4 months, given an initial population of 4,000 mosquitoes and a monthly growth rate of 25%. To find the population after 4 months, we use the formula for exponential growth:

P = P0 × (1 + r)n

where P is the population at the end, P0 is the initial population, r is the growth rate (expressed as a decimal), and n is the number of time periods.

Substituting the values, we get:

P = 4000 × (1 + 0.25)4

P = 4000 × (1.25)4

After calculating, we find that P = 9765.63. Thus, the population of mosquitoes after 4 months is expected to be approximately 9,766.

The mosquito population grows from 4,000 to approximately 9,766 over 4 months with a 25% monthly increase.

The initial number of mosquitoes is 4,000, and the population increases at a rate of 25% per month. To find the population after 4 months, we use the formula for compound interest:

P = P0 [tex](1 + r)^{t[/tex]

where:

Given:

Substitute these values into the formula:

P = 4000 × (1 + 0.25)⁴

First, calculate (1 + 0.25):

1 + 0.25 = 1.25

Then, raise this to the power of 4:

(1.25)⁴ = 2.4414

Finally, multiply by the initial population:

P = 4000 × 2.4414 = 9765.6

Thus, the mosquito population after 4 months is approximately 9,766.

Answer:

The answer is B 11/20

Step-by-step explanation:

To transform a decimal to a fraction you must do the following:

1. Multiply by an specific power of 10 until your decimal becomes a whole number. In this case 0.55 we multiply by 10 ^2 or 100 and we obtain 55.

2 Divide the decimal by this same power of 10 so that you do not change the original value. For example

0.55 *(100/100) = 55/100 As you see Im multiplying and dividing by 100 ( thats equivalent to 1 so it doesnt change the original number)

3 Simplify the fraction

To simplify your fraction you must find the Greatest Common Factor of 55 and 100. For doing this, you only perform a prime factorization. Divide 55 and 100 by the smallest common prime factor, besides 1. (For this case is 5) until you arrive to two number without common prime factors.

55/5 = 11

100/5 = 20

As 11 and 20 have no common prime factors it is the most simplified fraction

The length of XV in triangle VWX is approximately 26 feet.

To find the length of XV, we can use the trigonometric relationship in a right triangle. In triangle VWX, the measure of angle W is 25° and angle X is 90°. We can use the sine function to find the length of XV. The sine of angle W is equal to the length of the side opposite angle W divided by the length of the hypotenuse. So, we have sin(25°) = XV/61. Rearranging the equation, we get XV = 61 * sin(25°). Plugging in the values, we find that XV is approximately 26 feet.

Final answer:

The center of the circle described by the equation x2 − 4x + y2 + 8y − 29 = 0 is (2, -4), and the radius is 7 units.

Explanation:

The equation of a circle given in the question is x2 − 4x + y2 + 8y − 29 = 0. To find the center and radius of the circle, we will complete the square for both x and y terms.

This involves adding and subtracting the squared half of the coefficients of x and y to complete the square:

(x2 - 4x + 4) - 4 + (y2 + 8y + 16) - 16 = 29 + 4 + 16

(x - 2)2 + (y + 4)2 = 49

This equation is now in standard circle form, which is (x - h)2 + (y - k)2 = r2, where (h, k) is the center and r is the radius.

The center of the circle is therefore at (2, -4) and the radius is √(49) = 7 units.
