Answer:
4v^2-25
Step-by-step explanation:
(2v+5)(2v-5)
Using (a-b)(a+b)=a^2-b^2, simplify the product
(2v)^2-5^2
To raise a <u>product to a power</u>, raise each factor to that power.
4v^2-5^2
Evaluate the <u>power.</u>
4v^2-25
Answer:
A = P ( 1+ i )^n
A = 10,000(1+0.025)^10
= 10,000(1.025)^10
= $12,800.84
Step-by-step explanation:
A = future amount
i = interest rate
n = number of years
P = Present value
i.e i = 2.5% , P = $10,000 and n = 10 years
<u>Answer:</u>
1 cm : 10.5 km
<u>Step-by-step explanation:</u>
We are given that two towns are 31.5 km in real and are 3 cm apart on a map and we are to find the scale of the map.
For this, we can use the ratio method.



Therefore, the scale of the map would be 1 cm : 10.5 km.
I think this is find the LCM, so the answer would be 168
Answer:
69
Step-by-step explanation:
If every 175th person gets free admission, that means
175th
175 * 2 = 350th
175 * 3 = 525th
person gets free admission and so on...
This basically means <em><u>"how many 175s are there is 6742 (for first day) and 5487 (for 2nd day)?"</u></em>
<em><u /></em>
We would need to divide and see the WHOLE number, not the fractional(decimal) amount remaining. So
<u>1st Day:</u>
6742/175 = 38.53
This means 38 people will get free admission
<u>2nd Day:</u>
5487/175 = 31.35
This means 31 people will get free admission
In the 2 days, total of 38 + 31 = 69 people will get free admission
