THEOREM:
• <u>Pythagorean theorem</u>:— In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides.
ANSWER:
By pythagorean property,
x² = 4² + 8²
x² = 16 + 64
x² = 80
x = √80 units.
So, <u>Correct choice</u> - [A] √80 units.
Answer:


Step-by-step explanation:
Consider the provided number.
We need to find the approximate value of
to the nearest hundredth.
First find two perfect squares that the irrational number falls between.

118 is lying between 100 and 121, therefore the square root value of 118 will be somewhere between 10 and 11.


118 is closer to 121 as compare to 100.
Therefore, 
Consider the number 
First find two perfect squares that the irrational number falls between.

319 is lying between 289 and 324, therefore the square root value of 319 will be somewhere between 17 and 18.


319 is closer to 324 as compare to 289.
Therefore,

Answer:
9b+10s
Step-by-step explanation:
you are trying to find an expression for total cost after an unknown amount of hours. you need to multiply the number of hours (defined as b and s in this example) by the cost per hour given ($9/hr for the bike and $10/hr for the scooter).
this would result in the following expression: total cost=9b+10s
