Answer:
20(pie)
Step-by-step explanation:
Since the circumference of a circle is 20 feet, the formula for circumference is 2r(pie) with r=radius
(radius)2=diameter
(diameter)(pie)
20(pie)

Answer: 2*2*2*2*5</h3>
We have four copies of '2' and one copy of '5' multiplied together
This is the same as saying 2^4*5
=========================================
Explanation:
Divide 80 over the smallest prime factor, which is 2
80/2 = 40
Divide that result over 2
40/2 = 20
Keep going until you cannot divide by 2 anymore
20/2 = 10
10/2 = 5
We stop here because 5/2 isn't a whole number. We also stop here since 5 is prime. Circle all the primes that show up and you should have four copies of 2 and one copy of 5.
Therefore: 2*2*2*2*5 = 80
In shorthand, this condenses to 2^4*5 = 80
The factor tree is shown below. Other factor trees are possible.
Answer: 24 or 28
Step-by-step explanation:
√a² + 12 + b
√(-2)² + 12 + 14
√4 + 26
-2+26=<u>24</u>
2+26=<u>28</u>
24 or 28
I think it’s not equal because if you took (1)(2)(3). You would need to multiply them not add them. It would be 9 = (1,2,3)
Answer: 1.18 dollars
Step-by-step explanation:
Given that:
E = Euros
D = US dollars
If the equation showing the relationship between Euros and Dollar
is E = 17/20D
To find the equivalent amount of dollars for 1 euros, substitute E for 1 in the formula and make D the subject of formula
1 = 17/20 D
Cross multiply
17D = 20
D = 20/17
D = 1.18 dollars approximately
Therefore, 1.18 dollars have the same value as 1 euro.
