Arianna and Hannah are conducting an experiment to test the difference threshold for sense of touch on the forehead. For trial 1

, Hannah closes her eyes while Arianna gently touches 2 paperclip points 3 millimeters (mm) apart on Hannah's forehead. Then Hannah reports whether she could feel 1 or 2 points. For each of the next trials, Arianna and Hannah repeat this process, each time with the points 2 more mm apart. Hannah reports feeling 1 point until the points are 15mm apart, when she begins reporting that she feels 2 points. Which inequality best represents the trial numbers in which Hannah feels 2 points?
a. t > 6
b. t < 6
c. t ⥠7
d. t ⤠7

Answer:

t > 7

Step-by-step explanation:

2 paperclip points = 3 mm apart

After each trial, points are 2mm more apart ;

That is

Trial 1 : 3mm

Trial 2 : 5 mm

Trial 3 : 7 mm

Trial 4 : 9 mm

Trial 5 : 11 mm

Trial 6 : 13 mm

Trial 7 : 15 mm

Trial 8 : 17 mm...

Hannah reports feeling 1 point until the point are 15m apart which is equal to 7th trial

Hence, she starred reporting feeling 2 points after the 7 th trial

t > 7

Hence, the inequality

5 gallons of diesel weighs 37 pounds. How much does 3 gallons of diesel weigh? Do these quantities (volume and weight) vary dire
True [87]

Answer:

22.2 pounds and 1g = 7.4p

Step-by-step explanation:

Lets go in an inverse sense, finding firstly the constant variation and then the weight of 3 gallons.

The constant variation is the relation between gallons of diesel volume and pounds of diesel weight. For thise we would like to find how many pounds of diesel weights 1 gallon. We have the following equality:

5 gallons = 37 pounds

Now, lets divide both sided by 5, as we know the equality will still:

5/5 gallon = 37/ 5 pounds

1 gallon = 7.4 pounds

So, this is the constant variations: every extra gallons weights 7.4 pounds. We could also do this in terms of pounds, which means, parting from:

5 gallons = 37 pounds

Divide both sides by 37:

5/37 gallons = 1 pound

0.081 gallons = 1 pound

Every extra pound means 0.081 more gallons.

Now, as we want the weight of 3 gallons we can use our first relation and multiplying by 3:

1 gallon = 7.4 pounds

3 gallons = 22.2 pounds

MrRa [10]

Answer:

<em>y = x ÷ 2</em>

Step-by-step explanation:

We are given a table of values, which will be represented as ordered pairs (x,y) below:

(2,1) (4,2) (8,4) (10,5) (16,8)

We are required to select one of the functions that match the numeric relationship between x and y.

We could test them one by one, but at simple observation, we can note the values of y are half of the values of x:

2/2=1

4/2=2

And so on. Thus the only function that divides the value of x by 2 to find the value of y is:

y = x ÷ 2
