1.64/22 with estimation and an explanation?

1 answer:

7 0

What I did was move the points 2 time to the right (or multiply by 100) and divided by 2 twice to get 41/550. For a decimal, I used a calculator and approximated the answer to 3 significant figures (just to be safe).

You travel between these two mile markers and then find your average speed in miles per hour. Which equation does NOT represent

Jet001 [13]

Answer:

The correct option is C.

Step-by-step explanation:

The time in first figure is 3:00 pm and the time in second figure is 4:30 pm.

So total time taken by car is

$4:30-3:00=1:30$

It means total time taken by car is 1.5 hour.

The distance in first figure is 50 miles and the speed in second figure is 155 miles.

So total distance travelled by car is

$155-50=105$

It means total distance travelled by car is 105 miles.

The formula of speed is

$Speed=\frac{Distance}{Time}$

$Speed=\frac{105\text { miles }}{1.5\text{ hours}}$

Therefore option B represents the solution. Option B is incorrect.

Multiply both sides by 1.5 hours.

$1.5\text{ hours}\times Speed=105\text { miles }$

Therefore option D represents the solution. Option D is incorrect.

Divide both sides by speed.

$1.5\text{ hours}=\frac{105\text { miles }}{Speed}$

Therefore option A represents the solution. Option A is incorrect.

Option C can not represent the solution, therefore option C is correct.

What is the slope of the line through (3, 2) and (-3, 4)?

Angelina_Jolie [31]

Answer:

Slope =-1/3

Step-by-step explanation:

(3,2)..... x1 =3, y1=2

(-3,4).... x2=-3, y2 =4

Slope=(y2-y1) /(x2-x1)

Slope=(4-2) /(-3-3)

Slope =2/(-6)

Slope=-1/3
