Eric's mother drives to work in 20 minutes when driving at her usual speed. When traffic is bad,she drives 10 miles per hour slower, and the trip takes 10 minutes longer. What is Eric's mother's usual speed

Answer:

x = 8

Step-by-step explanation:

Given

- 4(- x + 8) = 0

- 4≠ 0, so

- x + 8 = 0 ( subtract 8 from both sides )

- x = - 8 ( multiply both sides by - 1 )

x = 8

Answer:

X=8

Answer:

Saturday: 1.5x

Sunday: 2x

Step-by-step explanation:

    For the the Chart, Saturday, we can automatically see that when 1 is inputted into the equation we get 1.5, as anything times 1 will equal the same number inputted (x). So we can try 1.5x and plug in every other x value and see what we get:

1.5(2) = 3

1.5(3) = 4.5

1.5(4) = 6

This verifies that the equation 1.5x works with this chart.

   For the graph its simple, do rise over run and your slope is 2/1 which is 2 so we have 2x for our equation so far and now to find the + or - at the end of the equation ( the "b" variable of the mx + b form) we just look at where does the function intersect with the Y-axis. Since it is at 0 we don't need to add a "b" variable to the equation so the equation for the graph is 2x for Sunday.

Answer:

y=x+9

Step-by-step explanation:

First, remove the parentheses.

Write in slope-intercept form. (y=mx+b)

Answer:

Pn=Po(1+r)^n

r=8.7%=8.7/100=0.087

Po=$70

n=1

P1=70(1+0.087)^1

=70(1.087)=76.09

=76

Answer:$76.09

Step-by-step explanation:

100%+8.7%=

 108.7%\,\,108.7\%108.7%

Whole balance before interest = 100%, then add on interest

108.7% of the current balance means 108.7100 of it.\text{108.7\% of the current balance means \(\frac{108.7}{100}\) of it.}108.7% of the current balance means 100108.7​ of it.

"Percent" literally means "out of 100."

108.7100=\frac{108.7}{100}=100108.7​=

 1.087\,\,1.0871.087

To find 108.7% of the current balance, multiply by 1.087:\text{To find 108.7\% of the current balance, multiply by \(1.087\):}To find 108.7% of the current balance, multiply by 1.087:

$70×1.087=\$70\times1.087=$70×1.087=

Answer: x - x1/ x2- x1 = y -y1 / y2-y1

x - 6/ -6-6= y - 1/ -1 -1

x -6/-12 = y -1 /-2

-2(x-6) = -12 (y-1)

-2x +12 = -12y +12

12y = 2x +12-12

y= 2x/12

y= x/6

Step-by-step explanation:

On the given graph the period is the distance between maximum points -7 and 3:

Answer:

The period of the sinusoidal function is 2π, i.e., the value of the function repeats at every 2π units.

From the origin towards right we can see that the distance traveled between 0 to 2π is 10 units

Therefore, 10 units is the right answer.

Answer:

2714 mm3

Step-by-step explanation:

   Volume of the material used in each cylindrical cracker is 2714 cubic mm.

         Volume = πr²h

Given in the question,

Material used in cracker = Volume of the whole cracker - Volume of the cylindrical hole

                                         = [tex]\pi (\frac{16}{2} )^2(18)-\pi (\frac{8}{2} )^2(18)[/tex]

                                         =  1152π - 288π

                                         = 864π

                                         = 2714.34

                                         ≈ 2714 cubic mm.

  Therefore, volume of the material used in each cracker will be 2714 mm³.
