Answer:

1/21 * 7  = 1/3

Step-by-step explanation:

The numbers in 1/3 divided by 7 are labeled below:

To make it a fraction form answer, you keep the numerator and multiply the denominator by the whole number to make a new denominator:

1

-------

3 x 7

 =  

1

-----

21

Thus, the answer to 1/3 divided by 7 in fraction form is:

1/21

To make the answer to 1/3 divided by 7 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:

1/21 = 0.04761904761

1/21 * 7 = 0.3333333333.... ( 1/3 )

The equation of c is an illustration of subject of formula

The equation of c in terms of r and t is c = r - 15/t

The equation is given as:

t = 15/(r - c)

Cross multiply

t(r - c) = 15

Divide both sides by t

r - c = 15/t

Subtract r from both sides

-c = -r + 15/t

Multiply both sides by -1

c = r - 15/t

Take LCM

[tex]c = \frac{rt - 15}{t}[/tex]

Hence, the equation of c in terms of r and t is [tex]c = \frac{rt - 15}{t}[/tex]

Answer:

a) growth

b) 3%

c) 6 years (since the beginning of the decade)

Step-by-step explanation:

Given:

The population P (in thousands) of Austin, Texas during a recent decade can be approximated by [tex]y=494.29(1.03)^t[/tex] when t is the number of years since the beginning of the decade.

General form of an exponential function: [tex]y=ab^x[/tex]

where:

If [tex]b > 1[/tex] then it is an increasing function

If [tex]0 < b < 1[/tex] then it is a decreasing function

a) The model represents exponential growth as 1.03 > 1

b) The annual percent increase of the population is 3%

1.03 - 1 = 0.03

0.03 x 100 = 3%

c) To estimate when was population about 590,000 set y = 590 and solve for t:

[tex]\implies 590=494.29(1.03)^t[/tex]

[tex]\implies \dfrac{590}{494.29}=(1.03)^t[/tex]

Take natural logs of both sides:

[tex]\implies \ln\left(\dfrac{590}{494.29}\right)=\ln (1.03)^t[/tex]

[tex]\implies \ln\left(\dfrac{590}{494.29}\right)=t\ln (1.03)[/tex]

[tex]\implies t=\dfrac{\ln\left(\dfrac{590}{494.29}\right)}{\ln (1.03)}[/tex]

[tex]\implies t=5.988069001...[/tex]

Therefore the population was about 590,000 6 years since the beginning of the decade.

Answer:

355 miles

Step-by-step explanation:

Figure out how far the car travelled in 1 hour - 3 hours can be divided by 3 for 1 hour, so do the same for the miles - 213 / 3 = 71 miles.

So we know the car travelled 71 miles in 1 hour.

Now just multiply the miles by 5 to figure out the answer - 71 * 5 = 355 miles

The volume of the solid whose base is a circle centered at the origin with a radius r is 16r³/3 cubed unit.

The equation of the circle is the equation which is used to represent the circle in the algebraic equation form, with the value of center point in the coordinate plane and measure of radius.

The equation of the circle can be given as,

[tex]x^2+y^2=r^2[/tex]

Here, (r) is the radius of the circle.

Rewrite this equation as,

[tex]y^2=r^2-x^2\\y=\sqrt{r^2-x^2}[/tex]

This will give you the half the length of the side. Thus, the length of the side of the square is,

[tex]s=2y=2\sqrt{r^2-x^2}[/tex]

The area of the square it square of its side. Thus, the area of the square is,

[tex]A(x)=s^2\\A(x)=(2\sqrt{r^2-x^2})^2\\A(x)=4(r^2-x^2})[/tex]

The volume of the solid can be got by integrating the area of the cross-section.

[tex]V=\int\limits {A(x)} \, dx[/tex]

Here, A(x), provides the area of the square at the point x. Thus,

[tex]V=\int\limits {A(x)} \, dx\\V=\int\limits_{-r}^r {4(r^2-x^2)} \, dx\\V=[ {4(r^2x-\dfrac{x^3}{3})}]^r_{-r}\\V= {4(r^2(r)-\dfrac{(r)^3}{3})}- {4(r^2(-r)-\dfrac{(-r)^3}{3})}\\V=4[r^3-\dfrac{r^3}{3}}+ {r^3-\dfrac{r^3}{3}]\\V=\dfrac{16r^3}{3}[/tex]

Thus, the volume of the solid whose base is a circle centered at the origin with a radius r is 16r³/3 cubed unit.

Step-by-step explanation:

The experimental probability of choosing Grace is 13.6% (17/125*100)

The theoretical probability of choosing Grace is 16.67% (1/6)

Each probability would change because they depend on the data set so if the data set changes, that means the probability will also change depending on the amount it changes.

Answer:

QR = 14.00 cm to the neatest hundredth.

Step-by-step explanation:

This is a right triangle with < P = 90.

So QR is the hypotenuse.

< Q is the angle opposite to the line PR.

sin Q = opposite/hypotenuse = PR/QR

sin 40 = 9/QR

QR = 9/sin40

= 14.002 cm.

Step-by-step explanation:

Answer:

  13. x=11; MN=65°; NP=115°; NQP=245°

  15. x=9; AD=108°; BC=23°; DC=139°; DBC=221°

Step-by-step explanation:

The marked arcs are congruent, so we can equate the given expressions for their measures:

  10x -45 = 6x -1

  4x = 44 . . . . . . . . . add 45-6x

  x = 11 . . . . . . . . . . divide by 4

The arc measures are found by using the value of x in the corresponding expression. Arcs around a circle total 360°.

  arc MN = (10(11) -45)° = 65°

  arc NP = 180° -65° = 115°

  arc NQP = 360° -NP = 245°

__

The sum of arcs around a circle is 360°. We can use this fact to write an equation involving the given expressions. Clockwise from A, we have ...

  90 +(2x +5) +(17x -14) +12x = 360

  31x = 279 . . . . . . . subtract 81, collect terms

  x = 9 . . . . . . . . . divide by 31

The arc measures are found by using the value of x in the corresponding expression.

 arc AD = 12(9)° = 108°

  arc BC = (2(9) +5)° = 23°

  arc DC = (17(9) -14)° = 139°

  arc DBC = 360° -DC = 221°

Answer:Slope=-240.000/2.000=-120.000
