Scenario: Tom and Jerry measured the length of a yardstick and the length of a foot-long string and obtained 92.44 cm for the le

ngth of a yard and 31.48 cm for the length of a foot.
1) Given the exact value of 1 yard is 91.44 cm and of 1 foot is 30.48 cm, find the measurement error in the results obtained by Tom and Jerry.

2) Tom thinks that the two measurements are equally inaccurate. Jerry thinks that one of the two measurements is more accurate than the other. Find the error in measuring the length of 1 yard as a fraction of the exact length of 1 yard and give your answer as a percentage.

3) Find the error in measuring the length of 1 foot as a fraction of the exact length of 1 foot and give your answer as a percentage.

4) In what ways could expressing measurement errors as a percentage of the exact value be helpful?

5) How would you compare measurement errors?

arron takes his dog for a walk afer school, he walks 5 blocks east and then 4 blocks north. if he was able to take a direct rout
nlexa [21]

Hi!

We are given the information found in the picture below.

Note: The directions aren't correct, but the triangle works for this problem.

The "direct path" is the hypotenuse of this triangle.

To find this, we use the Pythagorean Theorem, where a and b are 2 legs of the triangle, and c is the hypotenuse, aka the longest side of any triangle:

a^2+b^2=c^2

We know a and b and want c

4^2+5^2=c^2

16+25=c^2

41=c^2

Therefore, c is approximately 6.403

your local gas stations are having a price war during the past seven days they have lowered the price of regular gas by $0.2 eac
Serga [27]
<h2>Answer with explanation:</h2>

Let x denotes the number of days and y denotes the total change in gas price ( in dollars).

Given : During the past seven days the price of regular gas is decreased by $0.2 each day.

Rate of decrease =$0.2 per day

Then , Total change in gas price = Rate of decrease x Number of days

i.e.y= 0.2 \times x

i.e. y=0.2x         (1)

To find the total change in gas price in 7 days , we put x= 7 in (1) , we get

y=0.2(7)=1.4    

Hence, the total change in gas price in 7 days = $1.4
