Answer:
see below
Step-by-step explanation:
<h3>Given</h3>
- Distance is 142.2 m, correct to 1 decimal place
- Time is 7 seconds, correct to nearest second
<h3>To find:</h3>
- Upper bound for the speed
<h3>Solution </h3>
<em>Upper bound for the speed = upper bound for distance/lower bound for time</em>
- Upper bound for distance = 142.25 m (added 0.1/5 = 0.05)
- Lower bound for time = 6.5 seconds (subtracted 1/2 = 0.5)
<u>Then, the speed is:</u>
- 142.25/6.5 = 21.88 m/s
- 21.88 = 21.9 m/s correct to 1 decimal place
- 21.88 = 22 m/s correct to nearest m/s
You would have to sell approximately 52 bracelets per week in order to pay your fee.
190 ÷ 3.60 = 52.7
Answer:
b) 158
Step-by-step explanation:
The two horizontal lines are called parallel lines so x is the same as the given angle and the ones diagonal from them would be the same as well.
The answer is C) 16 blocks.
We will use the distance formula for this problem:

From your house to the internet cafe:

From the internet cafe to your friend's house:

Together, we have 10.2+5.7=15.9, which rounds to 16 blocks.
