Store A because 40% off of 120$ will equal 72.
Answer:
17ft
Step-by-step explanation:
What you're going to do is solve this backwards so to find volume the eqation is v=(pir^2)h, so what you're going to do is:
833pi=(pi7^2)h you cross out pi and square 7 833=49*h then you divide 49 from both sides and get 17
The money in the Felix's account will be $6798 when he is 21.
<u>Step-by-step explanation:</u>
It is given that,
- The amount deposited is $2000.
- The account earns 6% compound interest.
- It is compounded annually for 21 years.
<u>To find the money in Felix's account after 21 years :</u>
The formula used here is,
⇒ 
where A is the amount after 21 years.
- P is the initial amount deposited ⇒ P = 2000
- r is the rate ⇒ r = 0.06
- n is the number of times interest is compounded per year⇒ n = 1
- t is the time period ⇒ t = 21
⇒ 
⇒ 
⇒ 
⇒ 
Therefore, The money in the Felix's account will be $6798 when he is 21.
Answer:
Number 1 = 3, Number 2 = 1
Step-by-step explanation:
Create an each for the two number and make the sum of those two numbers equal to 4.
Number 1 we will make x
Number 2 will then be 2x - 5 (five less than two times the first number)
Equation is the sum of the two number and equal to 4
x + 2x - 5 = 4
3x - 5 = 4
Add 5 to both sides
3x = 9
Divide both sides by 3
x = 3
Test your answer.
Number 1 would be equal to 3
Number 2 would be 2(3) - 5 which is 1
Sum of the two numbers 3 + 1 = 4
Set the Ys equal to eachother them solve for X
3x-13=-4x+1
+13 to both sides
3x=-4x+14
Add 4x to both sides
7x=14
Divide by 7 to both sides
X=2
