Answer: a) interest earned is $308.2
b) $1983.2
Step-by-step explanation:
a) Interest is calculated by Principal × Rate × Time
From the question, principal is given as $1675; rate = 4.6% = 4.6/100 = 0.046; Time = 4 years
Slot the values into the formula to get the solution
=1675 × 0.046 × 4
= $308.2
Interest earned is $308.2
b) Balance on the account will be Principal + Interest earned
= $1675 + $308.2
=$1983.2
I hope this is clear, please mark as brainliest answer.
For the answer to the question above, I'll provide a solution for my answer below.
x^4 - 41x^2 = - 400
<span>=> x^4 - 41x^2 + 400 = 0 </span>
<span>=> x^2 = (1/2) [41 ±√(1681 - 100)] </span>
<span>=> x^2 = (1/2) (41 ± 9) </span>
<span>=> x^2 = 16 or 25
</span>
So, therefore, the answers for your problem are
<span>=> x = ± 4 or ± 5.
I hope my answer helped you. </span>
Answer:
Katy's family got to the beach at 9:55am.
Step-by-step explanation:
In order to find Katy's family's arrival time at the beach, you need to first add amount the amount of time they spent on each activity. Since there are 60 minutes in one hour, you can add up all the minutes together and then divide by 60 minutes to get the total time in hours:
55 minutes + 115 minutes (1 hr and 55 min) + 105 minutes (1 hr and 45 minutes) = 275 total minutes
275 ÷ 60 = 4 hours and 35 minutes
If Katy's family was done with their activities at 2:30pm, we need to subtract 4 hours and 35 minutes from 2:30pm to get their arrival time. 2:30pm - 4 hours = 10:30am, now subtract another 35 minutes to get 9:55am.
Answer:
The answer is ;
9x/2y^2
Step-by-step explanation:
Here, we want to simplify as far as possible
Let us take all the numbers one after the other
All numbers on numerator and denominator;
(4 * 9)/(2 * 4) = 9/2
All x
(x^2 * x^2)/(x^2 * x) = x
All y
(y^4 * y^4)/(y * y^9) = y^8/y^10 = 1/y^2
So the complete answer is;
9/2 * x * 1/y^2
= 9x/2y^2
