The equation is y = 1/8x + 7

Standard form equation is Ax + By = C, where A > = 0.

First eliminate the fractions by multiplying the equation by 8

8y = x + 56

Subtract x from each side

-x + 8y = 56

SInce x coeficient can't be negative multiply the equation by negative one.

Nancy and Mark commute to work, traveling in opposite directions. Nancy leaves the house at 7:00 A.M. And average 20 miles per h

vladimir2022 [97]

Answer:

They will be 170 miles apart at 10 AM

Step-by-step explanation:

Nancy has 15´ of head start which is 1/4 hr.

NHD = 20*(1/4) = 5 miles is her head start

Mark leaves at 7.15hs = starting point

Marks stop at when they are 170 miles apart = t

------------------------------

t = the time they are 170 miles apart

d= distance in miles Nancy travels in time t

170 - (d+5) = distance in miles Mark travels in time t

------------------------------

Nancy's equation:

(1) d = 20t

Mark's equation:

(2) 170 - (d+5) = 40t

---------------------------

(2) 170-d-5=40t

(2) d+40t=165

Substitute (1) into (2)

(2) 20t+40t=165

(2) 60t=165

(2) t=2.75

7:15 AM + 2.75 hrs (2:45hs) = 10 AM

They are 170 miles apart at 10 AM

check:

(1) d=20t

(1) d=20*2.75

(1) d= 55

---------------

(2) 170 - (d+5) = 40t

(2) 170 - (d+5) = 40*2.75

(2) 170 - d-5 = 110

(2) d=55

he radius of the base of a cylinder is 10 centimeters, and its height is 20 centimeters. A cone is used to fill the cylinder wit

Elis [28]

Volume of cylinder: $V_{\text{cyl}}=\pi r^2h$ , where $r$ is the radius and $h$ is the height. This volume is $\pi\times10^2\times20=2000\pi$ (cubic cm).

Volume of cone: $V_{\text{cone}}=\dfrac13\pi r^2h$ , with the same variables denoting the same parameters. This volume is $\dfrac13\pi\times5^2\times10=\dfrac{250}3\pi$ (also cubic cm).

The number of times it would take to fill the cylinder with water using the cone as a source would be

$\dfrac{2000\pi}{\dfrac{250}3\pi}=24$
