Answer:

y = 55x + 160

Step-by-step explanation:

The computation of the equation that represents the relationship between the total miles driven y and the number of hours x is shown below:

she starts at 160 miles so it would be y-intercept

So the equation form would be

"b" in y = mx + b

where,

m = 55

and b = 160

Therefore the equation would be

y = 55x + 160

The same is to be considered

Answer:

Step-by-step explanation:

A) In order to write the equations of the perpendicular bisectors of the segments, we need to know the midpoint and the slope.

The midpoint is the average of the coordinates:

  midpoint(A, B) = ((-3, 5) +(1, 1))/2 = (-3+1, 5+1)/2 = (-1, 3)

  midpoint(A, C) = ((-3, 5) +(-7, -3))/2 = (-3-7, 5-3)/2 = (-5, 1)

The differences between the coordinates of the points can be helpful:

  B-A = (1, 1) -(-3, 5) = (1+3, 1-5) = (4, -4) . . . . . reduces to (∆x, ∆y) = (1, -1)

  C-A = (-7, -3) -(-3, 5) = (-7+3, -3-5) = (-4, -8) . . . . . reduces to (∆x, ∆y) = (1, 2)

_____

A line through point (h, k) perpendicular to one with (∆x, ∆y) can be written:

  (∆x)(x -h) +(∆y)(y -k) = 0

Then the bisectors of AB and AC will be ...

  (x +1) -(y -3) = 0

  (x +5) +2(y -1) = 0

Their intersection point can be found by solving this system.

  (x +2y +3) -(x - y + 4) = (0) -(0) . . . . . subtract the 1st equation from the 2nd

  3y -1 = 0

  y = 1/3

  x = y -4 = -3 2/3

The point of intersection of the right bisectors is (x, y) = (-3 2/3, 1/3).

__

B) The intersection point is the circumcenter. It will be the same distance from any of the vertices.

That distance can be found using any of the vertices. Using point B, we find the distance to be ...

  d = √((-3 2/3 -1)^2 +(1/3 -1)^2) = √((14/3)^2 +(2/3)^2) = √(200/9)

  d = (10/3)√2

The distance to each vertex is (10/3)√2 ≈ 4.71.

3x+4x+4=109

7x+4=109

7x=105

check:

3(15)+4(15+1)=109

45+64=109

Step-by-step explanation:

It is given that,

The average distance from the sun to the planet Venus is about 108,000,000 km. The diameter of a human hair is about 0.0025 mm.

(a) In scientifc notation, the distance from the Sun to Venus will be :

There are 8 numbers before 1. It means

d = 1.08 × 10⁸ km

(b) In scientific notation, the diameter of a human hair will be :

There are 3 numbers after decimal. It means

D = 2.5× 10⁻³ mm

(c) Before comparing two measurements, both values must be converted into the same units.

Since, 1 mm = 10⁻⁶ km

D = 2.5× 10⁻³ × 10⁻⁶ km

= 2.5 × 10⁻⁹ km

For comparison divide the distance from the Sun to Venus and the diameter of a human hair.

[tex]C=\dfrac{1.08\times 10^8\ km}{2.5\times 10^{-9}\ km}\\\\=4.32\times 10^{16}[/tex]

Hence, this is the required solution.

Answer:

$992.00

Step-by-step explanation:

Where:

I = P x r x t

P is the principal amount, $800.00.

r is the interest rate, 6% per year, or in decimal form, 6/100=0.06.

t is the time involved, 4....year(s) time periods.

So, t is 4....year time periods.

To find the simple interest, we multiply 800 × 0.06 × 4 to get that:

The interest is: $192.00

Usually, now, the interest is added onto the principal to figure some new amount after 4 year(s),

or 800.00 + 192.00 = 992.00. For example:

If you borrowed the $800.00, you would now owe $992.00

If you loaned someone $800.00, you would now be due $992.00

If owned something, like a $800.00 bond, it would be worth $992.00 now.

Answer:

Basically do -19.5 divided by 3

The answer is -6.5

Step-by-step explanation:

Hope that helps :)

The rate of change in elevation is approximately -6.5 centimeters per second.

Math operations include division as one of its types. This technique involves splitting the phrases or numbers into the same amount of components.

To find the rate of change in elevation, we need to divide the change in elevation by the time it took to change.

The change in elevation is -19.5 centimeters (we use a negative sign to indicate the decrease in elevation).

The time it took to change is 3 seconds.

Therefore, the rate of change in elevation is:

rate of change = change in elevation / time

rate of change = -19.5 cm / 3 sec

rate of change ≈ -6.5 cm/sec

So the rate of change in elevation is approximately -6.5 centimeters per second.

Answer:

Adam's container

Step-by-step explanation:

Given

Adam

[tex]Weight = 3.5\ oz[/tex]

[tex]Amount = \$8.75[/tex]

Macro

[tex]Weight = 3.75\ oz[/tex]

[tex]Amount = \$9.75[/tex]

Required

Determine the better buy

First, we need to determine the unit cost per oz of each

i.e.

[tex]Unit\ Cost = \frac{Amount}{Weight}[/tex]

For Adam:

[tex]Unit\ Cost = \frac{8.75}{3.5}[/tex]

[tex]Unit\ Cost = 2.5[/tex]

For Marco:

[tex]Unit\ Cost = \frac{9.75}{3.75}[/tex]

[tex]Unit\ Cost = 2.6[/tex]

The better buy of both is the one with the smaller unit cost.

Since 2.5 < 2.6, we can conclude that Adam's container is a better buy
