Answer:
<u>Use Pythagorean:</u>
<h3>#1</h3>
- x² = 16² - 8²
- x² = 192
- x = √192
- x = 12.73, not an integer
<u>Not a Pythagorean triple</u>
<h3>#2</h3>
- x² = 40² + 9²
- x² = 1681
- x = √1681
- x = 41
<u>It is a Pythagorean triple (9, 40, 41)</u>
<h3>#3</h3>
- x² = 6² + 13²
- x² = 205
- x = √205
- x = 14.32, not an integer
<u>Not a Pythagorean triple</u>
80÷18≈4

Answer:
a. 35 Kilometres.
b. 60 litres.
c. 8150 sweets.
Step-by-step explanation:
<u>Given the following data;</u>
- Distance traveled = 770 km
- Number of days = 22 days
a. To find how many kilometres he traveled in one day;
770 km = 22 days
X km = 1 day
Cross-multiplying, we have;
22X = 770
X = 770/22
<em>X = 35 Kilometres.</em>
b. To find how many litres he would need to go 840 km;
1 litre = 14 kilometres
X litres = 840
Cross-multiplying, we have;
14X = 840
X = 840/14
<em>X = 60 litres.</em>
c. To find how many sweets are there in his car;
Number of sweet box, Ns = 326 boxes
Number of sweets in each box, Sw = 25 sweets
Total number of sweets = Ns * Sw
Total number of sweets = 326 * 25
<em>Total number of sweets = 8150 sweets.</em>
24 x 100 = 2400
2400 divided by 60 = 40
