Answer:

Katherine would have $109.54 more than Stella.

Step-by-step explanation:

Giving the following information:

Stella:

Initial investment (PV)= $6,100

Interest rate (i)= 0.065/12= 0.0054 per month

Number of periods (n)= 7*12= 84

Katherine:

Initial investment (PV)= $6,100

Interest rate (i)= 0.06625/4= 0.0167

Number of periods (n)= 7*4= 28

To calculate the future value, we need to use the following formula:

FV= PV*(1 + i)^n

Stella:

FV= 6,100*(1.0054^84)

FV= $9,589.5

Katherine:

FV= 6,100*(1.0167^28)

FV= $9,699.04

Difference= $109.54

Katherine would have $109.54 more than Stella.

Answer:

5.33 Seconds

Step-by-step explanation:

This is because you have to do the quadratic equation and solve.

The time required to hi the water is 5.33 seconds.

A quadratic equation is a second-order polynomial equation in a single variable x as ax^2+bx+c=0 with a ≠ 0 . A quadratic equation as an equation of degree 2, meaning that the highest exponent of this function is 2.

For the given situation,

The function is h(t)= -16t^2+16t+370

The roots of this function can be found by using the formula,

[tex]t=\frac{-b+\sqrt{b^{2}-4ac } }{2a}[/tex] or [tex]t=\frac{-b-\sqrt{b^{2}-4ac } }{2a}[/tex]

Here, a=-16, b=16, c=370

⇒ [tex]t=\frac{-16+\sqrt{16^{2}-4(-16)(370) } }{2(-16)}[/tex] or [tex]t=\frac{-16-\sqrt{16^{2}-4(-16)(370) } }{2(-16)}[/tex]

⇒ [tex]t=\frac{-16+\sqrt{23936} }{-32}[/tex] or [tex]t=\frac{-16-\sqrt{23936} }{-32}[/tex]

⇒ [tex]t=\frac{-16+154.712}{-32}[/tex] or [tex]t=\frac{-16-154.712}{-32}[/tex]

⇒ [tex]t=\frac{138.712}{-32}[/tex] or [tex]t=\frac{-170.712}{-32}[/tex]

⇒ [tex]t=-4.33[/tex] or [tex]t=5.33[/tex]

Time cannot be negative. So the value is 5.33.

Hence we can conclude that the time required to hi the water is 5.33 seconds.

Answer:

A. (x - 5)^2 + (y + 4)^2 = 9

Step-by-step explanation:

The standard equation of a circle is in the form:

(x - h)^2 + (y - k)^2 = r^2

where (h, k) is the center and r is the radius. We can substitute what we have:

(x - 5)^2 + (y + 4)^2 = 9

Answer:197.8

The formula for a cylinder is 3.14*r^2*h but if you don't round to the nearest tenth the the answer is 197.82034.

Step-by-step explanation:Step one mutiply 3^2=9, Step two mutiply 3.14*

9=28.26, Step three mutiply 28.26*7=197.82.But if you round 197.82034 to the nearest tenth which is moving one decimal place to the right you'll will get 197.8.

Answer:1 / 15 of the pitcher

Step-by-step explanation:

The pitcher is 1/3 full and 5 people want to equally share it.

The equal amount is found by dividing 1/3 by 5:

= 1/3 ÷ 5

= 1/3 * 1/5

= 1/15 of the pitcher

Each person gets 1/5 of the pitcher

Aunque no se anexaron opciones o incisos para contestar, podemos comentar lo siguiente.

Cada material en sus distintos estados de agregación, cambia de volumen de forma diferente, sin embargo todos lo hacen en cierta medida. A esta propiedad se le llama Estados de Agregación de la Materia.

Las substancias cambian su composición debido a la presión o al cambio de temperatura a la que son sometidos. A ese proceso se le conoce como el estado de agregación de la materia, cuando las moléculas y átomos que constituyen esa matera se ve sometido a una transformación en su composición.

Podemos reconocer comúnmente cuatro estados de transformación de la materia, que son, el estado de plasma, el estado gaseoso, el estado líquido y el estado sólido

Answer:

4212 square feet.

Step-by-step explanation:

If the blueprint's scale is 1 inch : 9 feet.

Square both sides

(1in)² = (9ft)²

1in² = 81ft²

Given the  gym's  area as 52 square inches, hence;

52in² = x

Divide both expressions

1/52 = 81/x

x = 52 * 81

x = 4212ft²

Hence the area of the actual gym  is 4212 square feet.

Answer:

2/15

Step-by-step explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.

Experimental probability is based on the result of an experiment that has been carried out multiples times

experimental probability that the next patient will be female and in

the age range 22-39 =  females in  the age range 22-39 / total number of patients

total number of patients = 56 / 420

To transform to the simplest form. divide both the numerator and the denominator by 28
