So this is plotting and graphing basically. First you have to 1) draw the x and y axis table
|
|
|_______
temp (°C)
2) Label the top of y axis (the line going up and down-vertical) dissolved oxygen content (ppm). The dependent variable- data collected will be graphed along this line

3) Label the side, x axis (the line that goes from left to right) temperature (°C). The independent variable- Is what I change, will be graphed along this line

4) I would recommend using two different colors to plot the difference in result on the graph....

5) On the graph lable x the temp 1-30 don't skip any #'s

6) On the y axis you're only aloud to plot whole numbers. I would do 1-14 and keep going
Hope this help :) I could draw it but I'm lazy.

Kalin walls at a streaky rate of 3 2/3 miles per hour. The beach is 4 1/4 miles from his home. How long will it take Kalin to wa
DENIUS [597]

Answer:

The time it will take Kalin will be 2h 33m

Step-by-step explanation:

First we will transform the numbers to work more comfortable

d = distance

v = velocity

v = 3 2/3 miles per hour = 3.33 mi/h

d = 4 1/4 milles = 4.25 mi

As the time it takes to go to the beach and back asks us, we have to do the distance 2 times

d = 4.25 mi * 2

d = 8.5 mi

To calculate the time it takes, we simply have to divide the distance by the velocity

t = d/v

t = 8.5 (mi) / 3.33(mi/h)

t = 2.55h

if we also want to express the minutes we can divide after the point .55 by 100 and multiply it by 60

(55/100)*60 = 33

t = 2h 33m

The time it will take Kalin will be 2h 33m

In Springfield, a specific town in the US, 6 women and 25 men earned bachelor degrees in 2000. In 2010, however, 391 women and 4
Vladimir79 [104]

Answer:

  • See below

Step-by-step explanation:

For women, the initial number is 6, constant rate of change is w, number of years is x.

<u>Find the rate of change and work out the required formula:</u>

  • 10w + 6 = 391 ⇒ 10w = 385 ⇒ w = 38.5

<u>Formula:</u>

  • W(x) = 38.5x + 6

<u>Similarly for men, we get:</u>

  • 10m + 25 = 410 ⇒ 10m = 385 ⇒ m = 38.5

<u>Formula:</u>

  • M(x) = 38.5x + 25

Solve for x. 3X - 4 3X - 8
Tems11 [23]

Answer:

x = 2

As x = 12/6 = 2

Step-by-step explanation:

3x-4+3x-8

3x+3x-4-8

= 6x-12

FACTORISING for check and set to zero

6(x-2)

6x -12 = 0

Cancel out left by adding 12 to both sides then applying /6 to both sides to cancel 6 left side.

6x--12 + 12 = 0 + 12

6x / 6  =  12  / 6

x = 12/6

x = 2

or balance as grouping by separation  = multiply at end by  -1

3x+3x = --4 - 8

6x  = - 12

x = - 12/6

x = - 2

x = - 2  ( -1 )

x  = 2
