Answer: the Ferris Wheel
Step-by-step explanation:
9514 1404 393
Answer:
A, C
Step-by-step explanation:
First of all, recognize that any basic arithmetic operation between a rational number and an irrational number will have an irrational result. That means, you can eliminate any answer choices that involve an irrational number.
Fractions and mixed numbers involving integers are <em>always rational</em>, so you only need to look at the radicals. You know 9 is 3×3, so is a perfect square, and √9 = 3 is rational. You know 5 is not a perfect square, so <em>√5 is irrational</em>.
Considering the above, any expression involving √5 will have an irrational result. That means you can eliminate choices B and D.
choices A and C will result in a rational number
_____
<em>Additional comment</em>
A = 6.8 +0.75 = 7.55 (rational)
C = 6.8 × 0.75 = 5.100 (rational)
Use the Pythagorean Theorem:
a^2 + b^2= c^2
a= one side= 68 mi
b= second side= 80 mi
c= hypotenuse= Greenville to Columbia mi
a^2 + b^2= c^2
68^2 + 80^2= c^2
square each number
4,624 + 6,400= c^2
11,024= c^2
take square root of both sides
104.995 mi= c
ANSWER: The distance from Greenville to Columbia is 104.995 miles (rounded to 105 miles).
Hope this helps! :)
The table of the number of customers illustrates two different patterns
Deli should expect 90 customers to serve during week 8
<h3>How to determine the number of customers</h3>
From the table, the even number of week increases by 10, while the odd number of weeks reduces by 5.
At week 6, the number of customers is 80.
So, the number of customers at week 8 is:
Week 8 = Week 6 + 10
This gives
Week 8 = 80 + 10
Week 8 = 90
Hence, deli should expect 90 customers to serve during week 8
