2. Lorena is trying to choose between two different savings accounts at H-Town Bank. She will deposit $3,500 dollars and will leave the money in the account for 12 years. There will be no additional money deposited or withdrawn from the account.
Answer:
First of all, this question is not complete. So, we will be hypothetically create two accounts and try to choose the one with the greater profit.
Choice 1 = X = Final Amount after 12 years = $5600
Choice 2 = Y = Final Amount after 12 years = $6285.50
Hence, Lorena should choose choice 2, as it gives more profit over than choice 1.
Step-by-step explanation:
First of all, this question is not complete. So, we will be hypothetically create two accounts and try to choose the one with the greater profit.
Initial Deposit Amount = $3500
Time period = 12 years
Let's Suppose Lorena has two X and Y choices of accounts at H-town Bank.
X = simple interest of 5% over the initial amount for 12 years.
Y = Compound interest 5% over the initial amount for 12 years.
Solution:
Let's calculate the profit for choice 1 = X
Simple interest = 5%
Initial amount = $3500
Time period = 12 years
Formula = A = P (1 + rt)
where, A = Final amount after 12 years
t = time period in years = 12
P = initial amount to be deposited = $3500
r = annual interest rate = 5%
Plug in the values to get the total amount.
A = 3500(1+0.05x12)
A = $5600 = final amount Lorena will get after 12 years.
Let's calculate the profit for choice 2 = Y
Compound interest = 5%
Initial amount = $3500
Time period = 12 years
Formula = A = P [tex](\frac{r}{n} + 1)^{nt}[/tex]
where,
A = Final amount after 12 years
t = time period in years = 12
P = initial amount to be deposited = $3500
r = annual interest rate = 5%
n = number of times interest rate is applied or compounded. = 12
Plug in the values to get the total amount.
A = P [tex](\frac{r}{n} + 1)^{nt}[/tex]
A = $6285.50
Hence, Lorena should choose choice 2, as it gives more profit over than choice 1.

Given: 5x + 3 > 4x + 7.
Choose the graph of the solution set.
[tex]\boxed{\boxed{\pink{\bf \leadsto Option \ A \ is \ correct . }}}[/tex]
Step-by-step explanation:For the number line refer to the attachment :
A linear inequality is given to us . And we need to find the correct number line. So the given linear inequality is :-
[tex]\bf \implies 5x + 3 > 4x + 7 \\\\\bf\implies 5x - 4x > 7 - 3 \\\\\bf\implies \boxed{\red{\bf x > 4 }}[/tex]
This implies that the value of x is Greater than 4 . That is the inequality can have all the values more than 4. So when we see the given number lines we see that the first number line represents all values greater than 4 .
Hence the first graph of the solution set represents the given linear inequality.Answer: B is correct
Step-by-step explanation: Tried a on the test, got it wrong, then tried b and got it right.
The planet mercury makes its circuit around the sun in 88 days. Venus takes 225 days to complete it's circuit. Venus's travel time is what percent of Mercury's travel time?
Answer:
255.682%
Step-by-step explanation:
From the above question:
The planet mercury makes its circuit around the sun in 88 days.
Venus takes 225 days to complete it's circuit.
Venus's travel time is what percent of Mercury's travel time?
This is calculated as:
(Number of days Mercury take to complete it's circuit/Number of days Venus takes to complete it's circuit) × 100
= 225/88 × 100
= 2.5568181818181817 × 100
= 255.68181818%
Approximately = 255.682%
Venus's travel time is 255.682 percent of Mercury's travel time
Solve the literal equation for y.
2x – xy = 3
Answer:
Step-by-step explanation:
2x-xy=3
-xy=3-2x
y=3-2x/x
Answer:
[tex]y = - \frac{3}{ x} + 2[/tex]
Step-by-step explanation:
So we want y to be on a side by itself.
2x-xy=3
Subtract 2x from each side
-xy=3-2x
divide each side by -x
[tex]y = \frac{3}{ - x} + 2[/tex]

Oak Street and Elm Street run parallel to each other. When Main Street
intersects them, it forms interior 26, measuring 70°. What is the measure of
24?
Answer:
110°
Step-by-step explanation:
The consecutive interior angles theorem states that when two parallel lines are cut by a transversal, the pair of angles formed which lie inside the parallel lines on the same side of the transversal are known as consecutive interior angles. This consecutive interior angles are supplementary (that is add up to 180°).
Therefore:
∠4 and ∠6 are consecutive interior angles. Hence:
∠4 + ∠6 = 180° (sum of co-interior angles)
∠4 + 70 = 180
∠4 = 180 - 70
∠4 = 110°
Answer:
110°

John's family visited his grandmother over the weekend. the drive to her house was 2 hours at their usual speed. the trip back took 15 min longer because traffic was bad and they had to drive 5 mph slower. how many miles away is Johns's grandmother's house?
The distance to Johns's grandmother's house is 90 miles.
SpeedSpeed is the ratio of total distance to total time taken, it is given by:
Speed = distance / time
Let x represent the speed that John used and d represent the distance, hence:
x = d/2
Also when taken 15 minute longer (0.25 hours):
x - 5 = d/(2 + 0.25)
x = d/2.25 + 5
Equating:
d/2 = d/2.25 + 5
d = 90 miles
The distance to Johns's grandmother's house is 90 miles.
